Mikuzzi

Got the bike back and is running well. I also got back the offending bits of innards so thought I'd post a pic for interest. If this was a bad batch, most would probably have failed by now. I was staggered at how much material had worn off both the cam lobe and the tappet (lifter? what's the right term?). There was some talk at the workshop that inadequate lubrication in the area may also be an issue, based on the fact that the replacement cam had much larger, repositioned oil galleys.

How great is that! Gave me a grin that hurt- thanks Gavo

Thanks Mike -The oil pump has been stripped and checked amongst other items. Just in limbo at present waiting for parts to arrive from Europe.....waiting....waiting....a long way away, Europe...

I took my bike to a local race stand fabricator. He ran a measuring tape over it and made a stand based on the OEM item but with removable lever arm and, the whole thing is able to fold flat for storage. Not overly cheap but it does what it says on the tin every time - very solid.

Tom M thanks for the link – must admit I got a bit depressed about halfway through the read when consensus seemed to be that the engine was now shot and should be sent back as a warranty claim – no option there for the V11. Interesting magnet idea. Is there a magnetic sump plug available (I think my wife's BM has one)?

My Ballabio is undergoing surgery at the local Guzzi workshop. Tappet noise started to get quite loud during a fairly gentle (honest!) morning ride and it turns out that the microns thick hardening on the timing lobes of the camshaft has worn away and the tappets are chewing well into the metallic cheese underneath. The tappets themselves have also worn. The mechanic told me today that there's around 70 thou. of material missing – well, not missing, just now mixed with the oil. The bike was made in 2003/2004 and a search here says that was when the factory was outsourcing component hardening duties. So, what do I need to look for/be mindful of after repair? I've asked that the oil pump be stripped and cleaned and the mechanic's going to pop the shell bearings in the bottom end to check condition, flush the oil system renew filter etc.. Any advice? Btw, the bike has done just 14,000Km – a bit disappointing that.

I think the Voltage is stepped down to 5V, the adapters use a few mA even without the GPS plugged in but that's enough to drain the battery over 2 or 3 weeks, connect your multimeter in series you will see (provided that the meters fuse isn't blown of course, try it with the GPS installed to be sure) I'm getting 0.3 Amps with the Zumo in the mount and working, and 3.3mA with just the mount by itself (disclaimer - I'm using a multimeter that cost all of $9 so accuracy may not factor!) Even a $9 meter would be better than +/- 10% A 10 Amp hour battery would be at 1/2 charge 5/0.0033 = 1,500 hours (2 months) So...my Ballabio has a 13 AH sealed battery. The GPS mount will take this down to 80% charge in approx 4 1/2 weeks. Add the normal self discharge for these type batteries of around 2.5% per week and I'll get around, what, 2 1/2 to 3 weeks from full charge to 80% - I've got to ride more!

I needed the GPS in a hurry so wired up a Garmin Zumo mount directly to the battery - the supplied cables have an in-line fuse. Obviously the mount is live all the time so the GPS comes on as soon as it's fitted to the mount. I'm convinced that there is a small drain on the battery from the mount itself - at least the battery has started losing more charge between rides than before. Next job is to change the supply from the battery to a switched source.

Nice. Thanks Roy

Replaced the Metzler Sportecs at 10500 Km (not all my K's - they were on the bike when I got it) with Angels and liked them straight away. Felt much better - possibly due to fresh unworn profile, but made a big difference.

If the plug is the sort thats installed from the outside of the tyre then they are for short term emergecy use only and the legal requirment in Oz is the plugs with the mushroom head that must be fitted from inside the tyre. How do I know this? 4weeks ago and a week before a trip i got a rear flat the bike shop that repaired it said this was the requirment. I rode 2 up fully loaded QLD to VIC, started to go flat at Reefton spur (slowly) tore the rear up a fair bit, bought new pilot2 road in Melbourne> with the mushroom type it's physicaly impossible for it to blow the plug out but can you ever be 100% on what the tyre case will do when dammaged. Gavo, thanks - I hadn't considered the legal aspect, although in VIC we don't have to go through a yearly check at rego time like NSW (and QLD?). I'm taking the wheel to a bike tyre specialist tomorrow to get it plugged properly with the tyre off or, changed for a new one if it looks too manky from the inside.

The tyre pressure hasn't budged in 3 days and I'm pretty comfortable running on it for a while (and monitoring as suggested). I suppose I was interested to hear if there had been any known catastophic failures of a plugged tyre as opposed to the repair failing and the tyre losing air the same way as, say, getting another puncture. Thanks for your input guys.

On the weekend I had my rear tyre punctured with a 40mm long wood screw. I plugged the tyre with a kit that uses shaped rubber plugs (not the cord type). The repair got me home without problems, so the kit did its job. Checking 24 hours later the tyre is not losing any air and the plug looks ok. My head is saying, ditch the tyre and replace it - it’s a Pirelli Angel ST with just 1000Km on it, my wallet, though, is complaining loudly at the prospect. I checked an old 2007 thread on here where opinion was pretty much divided down the line between replacement of a plugged tyre or running through full life as long as the plug was good. My question then is this: Is there anybody here that has had a plugged tyre fail during “normal” use?
