  1. Yup, there's no way to drift in the new race with the shaft in place. Internal extractor would have to be very specialised as there are only two small cutaways in the register for the rave and the rest of it the register is wider than the bearing.
  2. If your swingarm bearings come out in chunks you need to replace them. If you want to you can spend ages chasing aftermarket ones but I've had no success as the 'Usual' design for these in RS format won't fit or work. Buy new bearings and new seals for the frame and then start the painful bit. First up you need to remove the driveshaft. This is retained by an expanding circlip on the gearbox output shaft. Get a podgy bar or large screwdriver and lever the front yoke back against the clip. Then use a copper hammer to deliver a mighty blow to the front yoke in a rearwards direction. This will pop the yoke off the circlip and the shaft will drop off, (It helps to have an assistant to hold the shaft.). Then you have to grind up a long, sharp edged, drift that can be poked through from the opposite side of the frame and be hooked up in the small cutaways in the bearing registers in the frame underneath the outer race of the bearing. Once you are sure the drift is engaged a few mighty thwack with a 4lb hammer should spit out the outer race from the frame. Clean it all up and then repeat for the other side. The new outer races can then be driven into the frame using an old outer race to biff them in. New seals can then be glued into the frame, packed cones inserted and the shaft put back onto the output shaft, (Make sure it is pushed on with sufficient force to ensure the circlip slips into place to lock the shaft.) after which the swingarm casting can be fed back up over the shaft and slipped into place. Once the swingarm spindle is inserted and tightened into the swingarm the castellated preload collar can be inserted and tightened down just far enough to preload the bearings. After which the two pinch bolts can be tightened, the boot re-attached and cable tied in place and the rest of the linkage and arse end of the bike reassembled. It's getting the outer races out of the frame that is the biggest shit of the whole job.
  3. Jaap, don't be daunted, it's really not that hard. Tie the front end down. Jack the bike up under the sump using a scissor jack and something to spread the load to get the rear wheel off the deck. Remove the exhaust, rear brake and wheel. Remove the side plates that hold the footrests. You have to disconnect the gear linkage rod and rear brake light switch to do this. Now you can tackle the linkage bolts. Note when you remove the one that goes through the shock to the swingarm there is a top hat bush in the swingarm. Don't loose it and remember it goes in from the inside adjacent to the shock eye! Don't forget the wishbone that pivots in the frame also has a bearing at the front that will need the same treatment and check the wishbone carefully for signs of damage. Take both wishbone and linkage over to the bench and carefully press the inner races out of the bearings. Not all the way, just far enough you can get a good squiz at the needles. If they look OK but just dry get a glob of grease on your finger and massage it into the needles before pushing the race back through the bearing and out the other side about the same amount. Repeat the greasing operation. Do this to ALL of the bearings. It is best to do this over a piece of white sheeting or the like as if you push the inner race too far it's likely the rollers, and there are lots of them, will tumble out. The reality is that if they do they will probably be rusty and buggered anyway. Note that in the wider parts of the linkage there are two sets of bearings side by side so be careful pressing out the inner race. If you find the bearings are rusty and beyond use, (On a 2008 bike, if they have never been inspected and greased this is highly likely.) you'll find it is about the same price to buy the entire linkage as it is to buy all the bearings, races and seals and then press the wretched thing apart and rebuild it. The savings in time/labour cost make it far more sensible to buy a new linkage. Just grease it properly before installing it. For now though leave it as you need to remove the swingarm. First clip the two cable ties that connect the rubber boot between the swingarm and gearbox. Remove the bevelbox after disconnecting the reaction rod. Then undo the pinch bolts that tighten the swingarm onto the castellated preload collar that preloads the swingarm bearings. The collar can then be undone and removed. Although a 'Special Tool' helps it's perfectly easy to undo it with a 'C' spanner as well. Once moving it usually unwinds by hand but wrap it in a rag as the corners of the castellations are sharp and ouchy! You then need to undo the swingarm spindle which requires a 14mm Allen socket or you can double-nut a suitable bolt to wind it out. Once loose it can be withdrawn from the left through the swingarm. Once it is out of the way the swingarm can be slid off down the driveshaft and removed. Take care with it. It is a very light casting and is only really designed to be strong in one plane! Do not biff, drop or otherwise abuse it! Once the swingarm is out of the way the swingarm bearing cones can be plucked out of the frame. Unless you are very lucky the chances are they will look something like the ones shown in the post above. If you are lucky make sure the inner seals are facing the right way and are secure in the frame and simply re-pack the bearings with as much bloody grease as you can get into them and stick them back in the frame. Check the shaft trunnions for tight spots or wear and if they're OK just spray a bit of chain lube up the splines and start reassembly. If, as I suspect, you find that the bearings are 'Donald Ducked' and the races are rusty and worn you'll need to replace them and this is where you'll enter a whole new world of pain! I'll cover that a bit later if you want me to? Pete
  4. Funny story. Couple of years ago they set the drug bus up on the hill coming out of Queanbeyan and were pulling over everyone. I was on the Griso with Mistral Hi-Pipe with dB killer in and the bloke in front was on an R6/R1 type thing. He had not only an open pipe but had tried that thing that 'tards do of mounting his numberplate inboard of the wheel in front of the shock. Oh my! That was fun seeing him get the third degree as they defected him on the spot, made him unscrew his plate, drug and piss tested him and then told him to @#!#$# off and walk home! They drug tested me but probably only because when they asked me if I'd ever taken narcotics I said "Shit yeah!" But then explained the last time was probably close to forty years ago and it was really shitty sulphate and I was ripped off! Not huge on the sense of humour that one! No issues with the noise though. Even though my Griso sounds like cheesgraters fornicating in an iron tank!
  5. But shitty ribbed tyres are 'COOL' Phil! Get with the programme! It doesn't matter if it handles like a fridge or you get coated in road shite because it doesn't have mudguards! It's 'COOL' because back in the 'Good Old Days' that's what motorbikes had and of course worshipping stuff that was considered barely satisfactory when we were young is all the rage because everything back then was wonderful! Or not......
  6. Definitely smallblock. V35 Imola 4V maybe? Or V75 Targa? Given its somewhere in SE Asia I believe it is most likely a 350 variant.
  7. Royalties can go to MSF. I am blessed with so much that I don't need the money from a few plates to fund my retirement. I'd prefer it went to a good humanitarian cause.
  8. Austria? Australia? WGAF as long as there is beer, motorbikes, comely wimmins and games you play with a bloody great hammer called the 'Terminator'! (I kid you not! There is a croquet mallet called 'Terminator!)
  9. I fear that we'd have to go to the bowling club for that, (Shudder!) but unlike 20-25 years ago when all the pubs in Queanbeyan were Friday night bloodhouses and DIY rhinoplasty centres most of them have been very nicely renovated and serve not only good scoff but some decent BWS! All is not lost!
  10. Oh dear. Someone posted a pic of a podgy bar! We're doomed! In a desperate attempt to do something to entertain ourselves in retirement Jude and I have been looking for a 'Sport' or 'Passtime' to get involved in. We know loads of people who are in to lawn bowls but they are all dull as ditchwater and as sharp as bags of wet mice so we ran away from that but in Queanbeyan, just up the road, there is a croquet club! Now yer talkin'! They give you a WEAPON, a bloody great hammer! Tops! Pete
  11. No spark or injector pulse screams phase sensor.
  12. As I've said, add ten bucks to the cost and donate it to Medicienes sans Frontiers and I'll be fine with that. If you can undercut the thieving turds at Guzzibits? So much the better. I know they have a 'Good reputation' but they are thieves and scumbags and I'd be happy to see them go bust.
  13. The design does what it needs to do, I haven't bothered modifying it. Crankcase pressure is always going to vary due to the 90 degree, shared crankpin design. The only way to reduce it would be increase the volume of the case or enlarge the vent. Pete
  14. Previous aluminium plates I've made for our old race bike were up to 1.5mm thick. To be affective as a windage plate as well as a baffle you run the oil just below the plate. Because the volume of the crankcase isn't constant as it lessens it will attempt to flex the plate downwards and as it increases the reverse happens so the plate will vibrate like the skin of a drum. The alloy plates all had a tendency to crack and disintegrate, hence the choice of stainless. Pete
  15. Stainless steel and yes they are heavy, but they won't crack and fall apart! They're going in a Guzzi fer Christ's sakes a few extra ounces isn't really an issue!
  16. Oh Jesus, not another re-hash of that tired old photoshop turd! It makes my brain hurt.
  17. This week we've got a Cafe Sport in and I'm going to introduce Michael to the wonders of V11's. Damn nice bike, it's that that prompted the new run of plates as it hasn't got one. The reason I stay with the 2mm plate is I'm a bit worried about vibration causing cracking if I go much thinner. I might just be being paranoid though...... Pete
  18. I've just had another run of plates done. Only got five done this time but I can up the number if required. Yes, the doppelgänger plate is an exact copy of my design and was stolen without my consent by the thieves at Gutzibits or whatever they call themselves. As I've said before, if they'd just asked me I would of said add £5 to the cost of each one and send it as a donation to Medicienes sans frontiers and it would all of been good. As it is they can go and roger themselves with a rusty star-picket. Oh, and sorry to anyone who tried to contact me about the plates. As mentioned in another thread a lot happened last year which meant I was a bit 'Under the pump', most of my work is with 8V CARC bikes nowadays and I simply didn't have the time or inclination to get more plates made. Now Michael is out of hospital and back at work, as long as my health holds together, I would be able to run up batches as required.
  19. That's my offsider Michael's workshop. His family also have a farm and have done for a long time, hence the old farm equipment. Since his return after his stack on his Aprilia we're working on making his workshop wheelchair friendly as he's now a paraplegic, (Last year was really a nasty one for us. Ron, Mark and Michael all stacked quite badly. Mark busted his Tib and Fib and is now full of Titanium rods. Ron bust something like seven ribs and a few other bits and was out of action for months and Michael bust his back, collar bone, nine ribs and split his sternum open and is now chairbound. @#!#$# 2018!) In our filthy socialist country our 'Green slip' insurance scheme offers Michael lifetime support so both he and Motomoda are getting a lot of help to enable him to continue working, not just in his current shop but in the new one being built next to his new townhouse that is being constructed on his parent's block in Bungendore. I'll keep his indolent, malingering nose to the grindstone! Pete
  20. Our efforts tend to be more road orientated, (That's Beetle sticking the datalogging kit on his 1400.) Our mate Ron has a dedicated track bike though. (Both of these clowns had serious stacks last year but thankfully have recovered!)
  21. Titanium exhaust valves, (Lighter.) but roller tappets, (Heavier.) and the POS still won't rev beyond 8,000! 85 HP? Kiss my huge, sweaty, antipodean arse! I part my buttocks and break wind fulsomely directly in the face of this insult to Moto Guzzi's heritage! On TI valves? I suggest you do some reading up on RSV-4's....... Pete
  22. Nobody's going to be looking in there again in your lifetime! WGAF what it looks like as long as the oil stays on the right side of the gorilla snot?!
  23. @#!#$# mate, I haven't even started! Nice project by the way. I've just sold all my pre-2000 stuff, all of it, but if I can help in any way, let me know. Pete
  24. Even without the poison dart of Piaggio ownership Guzzi seem to perennially shoot themselves in the foot. Why abandon the four shaft gearbox for example? While the six speeder in the CARC bikes is a good box and absolutely bulletproof, (In ten years I've never had one apart because it was broken!) it is longer and not as slick as the four shafter if set up correctly. Then they poisoned the reputation of the 'Nuovo 8V' with the flat tappet fiasco! They even tried to destroy the reputation of the smallblocks by producing a run of them with no crank thrust bearings! Now the styling and development is all being done by talentless spivs I hate to think what they will try and foist on us next! That's OK though, at least they did get to build the CARC bikes and they for me will remain the pinnacle of development and my muse. I'll be retiring ASAP once we have Michael set up to continue working and I can become a cantankerous old suspender-snapper and spend my time talking about the 'Good Old Days'! My arse.........
