    Hello to all , We are looking for wheels for our Le Mans Race motorbike. We are allowed to use 17" wheels because of the difficulty of finding race rubber. So to that end does anyone out there know of a wheel manufacturer building carbon fiber or mag wheels to fit our motorbikes. I can find 18" ones but finding 17's is starting to be a bitch and Guzzi OEM wheels weigh a ton ! Thanks in advance Rich
  2. Hello again,

    Sorry that I've not been on the form for so long.  Had a bad crash and I'm just starting to get going again.  Actually was starting when the Covid-19 got going.  Back at it again.

    We're building four motorbikes to race next season.  One is a Le Mans, Honda NC-30 and two 1982 GS1100s All to be raced in Vintage classes.

    First stop next year is Phillip Island Classic then the Mexican TT after that we are going to try for some of the UK vintage events.

    I kind of lost track of where we are here so "PLEASE " let me know if there's anything.

  4. I'll do what I can with getting pic's. This; I will admit is not my forte but I'll see what I can do/ Thank you all for the support. Racing IS FUN; but having folks rooting for you make it that much better. CHEERS !
  5. I have returned ! Bikes have all been loaded into their respective crate (Just a FYI we get our shipping crated from a PDI shop in Williams ,Ca Triumph crates seem to be the best) we dropped them off at the Brokers end of the week and they'll soon be on their way to Australia. Gina and the team will meet again on January the 22 at Phillips Island. There was quite a lot of discussion on the fueling problem we were having. As is often the case it proved to far simpler than one might imagine. The fuel cap did not match up correctly with the tank flange thus closing off the vent hole
  6. Hi Phil, Good to hear from you. Here in the states we're known as the Purple Gang. Being that the bike is purple and all. Name of my race company is Sportcraft. Do come and find us and say hello And Ciao back at ya,
  7. Time to bring you all up to date on the Moto Guzzi Racer. We last raced the bike at Millers then pulled the plug on our racing so we could get things ready for 2019. As some of you may recall the motorbike was build by Ed at Guzzi Power specifically to race in the Manx GP on the IOM. Because of the distance of those races and the very high speeds we had been using the tallest gearing Guzzi makes. On shorter courses this was costing us quite a bit in the top end department. At Millers we raced on a very short course; far shorter than I have ever seen at this track. It did show us h
  8. Checking back in. And again thanks for the ideas. The bike had spend quite a lot of time on the dyno and had never had a fueling problem so under these conditions I ask myself what things are different from the dyno run and running on the race track ? 1. Ambient temperature is different (high 80's verses 100's) BUT when we raced at Willow Springs it was in the 90's ?? 2. We were at 5000 feet in altitude Willow Springs is around 2000' 3. We were getting our fuel from a MotionPro fuel bottle rather than the Moto Guzzi tank 4. The Miller course was lots of short straights and tight
  9. JRD, Glad you like the write ups. We are not running OEM carburetors. As the rule allow for the change we have switched to Mukuni's. The reasons for the change is multi faceted; we already had a large supply of jets, gaskets, needles not to mention the Muki's flow better. We also are considering more heat protection for the fuel components. I am even considering making small (4" X 4") shields to go between the carbs and the cylinder fins. I totally agree that just looking at where the heat is generated and where the fuel is moving makes me wonder if vapor lock could be part of
  10. 68C, Not really how these carburetors function. Fuel tank is the large fuel reservoir and the float bowl is more or less the small fuel holding tank. Fuel flow between the two is controled by a needle valve and float. Fuel flow is from gravity. The carb needs float bowls because fuel use is always fluctuating. Electric fuel pump easily over power the needle valves and when used are controlled by pressure regulators set at very low PSI. After examining the fuel system our conclusion is that the problem (this is often the case) is from several inherent weaknesses. Remove any one and
  11. Chuck, Keeping in mind that nothing on the engine is OEM it can't be electrical as the ignition is all electronic. The engine does not really run totally out of fuel but rather goes into a fuel starve mode. What Wade told me was that it starts to fall off and as soon as he backed off and hit it again it would pick up. When I checked all the fuel related things, from the tank venting to the float height what seem most out of what I call spec is the size of the petcocks. Everything else was looking correct. The only other cause we consider would be vapor locking (weather was quite ho
  12. Back at Ya, Will see what I can do about pics. Tons of folks came by and were taking pics but I was kinda focused on the motorbike. I think that Eric on our team (Because of Gina's PURPLE tones we have become known as the PURPLE GANG) may have taken some. I'll chat him up and see what I can do. Thanks for your interest. Oh, almost forgot. As I went back over our notes from Miller I noticed that we seem to be loosing speed at the end of the straights. Talked to Wade the rider and he said that he would chop the throttle when she stopped pulling and then hit it again and she'd s
  13. Hello Again, After we returned from Miller the team all got together and took time to discuss the weekend and the results. The bottom line is we improved all through out the weekend but we are still getting beat. In the last race Wade our rider took on the entire field and got the bike into and through turn one in the lead. And that's the good news. After that we kept getting passed until we ended the day in third as I posted before. We finally have come to the conclusion that our problem is in the gearing. Gina (our pet name for the motorbike) was built for the Isle of Man, Wade has
  14. Again sorry for taking so long to reply to the forum. I was going over the oiling problems and the comments about same plus those regarding positive/negative issue etc. I began my racing working on a type of race car called a Formula Junior. These engines tended to pump oil out at a alarming rate. When I began seeing this problem starting to begin in the Guzzi I tackled it in the same way we did the F Juniors. "KISS' we first tried to release the crankcase pressure with venting. As oil will escape through said venting we created small inline catch tanks in the form of small in li
  15. Still at IT ! Sorry I have been AWOL for a while but life just gets in the way. Was first off doing a MERA (Motorcycle Endurance Riders Assoc.) event out of Salt Lake City. Don't ask how I did there; 36 hours with the temp. in triple digests and I bailed out and headed to a hotel with AC. We did race at Willow Springs and did OK for it being a new motorbike found and fixed some teething problems. Last weekend (Labor Day) we raced Utah Motorsport and got a third (not really a big deal and there were only 4 bikes) but did shave over 14 seconds off our times. Bike is running go
  16. Thanks for the feed back ! All the minds really do help. Each idea is more information and as with the oil problem allows us to come up with workable answers. KB: Thank you for the people and companies. We will contact them to make sure we end up with the best bits. Three years ago Wade popped an engine on the Island (one of the faster spots) a rod bolt broke and the internals vacated between the barrels and head. Oiled the whole bike as the leak was above the catch pan. When the corner marshals got to him all he could say was "glad to be here and alive" . We in fact headed over to
  17. Hello Again, We just got back from racing at Willow Springs (Southern California Desert for those on the right coast) racing with AHMRA. Good fun nice folks and more learning. It was rather difficult to get any real good lap time as the wind was rather errrrr, strong would be an understatement. If I heard correctly we were dealing with winds in the 40 to 45 MPH range and the bike has a full fairing so that even added to the trouble. Willow Springs is a great place to work on over all set up so we focused on that. Wade got down to a few 43's and for our class that puts us about
  18. Luhbo, Not sure of what you speak but will refer to Gina as a Motorbike in the future. I have a friend here in the states that is always busting me on my Italian gender errors so I'll be a tad more careful. Cheers
  19. Hello All, As any of you who are following the IOM Le Mans Moto Guzzi project we have begun the post race look see. Our focus was on the oiling problems. I might add that it was by no means terminal but was enough to get the tech boys hands reaching for the meatball flag. So for the most part we found that our outflow lines from the engine may have been larger then the vent from the catch tank and there for causing a slight over-pressure in the catch tank itself. Here in lies the reason for this post. Can one of you Guzzi brains explain what the rear hose fitting that comes fro
  20. Mark, You are quite right Red Bull is the new blessing for long distance motor racing transport. We also discovered that once south of the Mason-Dixon line the appropriate beverage choice was RC cola and boiled peanuts could be included as a dietary supplement. Cheers
  21. I continue to post to the Technical Topics because for me it has become more of an engineering adventure. It seems to just belong here rather than what my Moto Guzzi did today. So we are just back from Daytona. We raced our Yamaha R-6 in the 200 as a means of getting track time. That did not turn out as we'd had hoped as we were plagued with electrical gremlins throughout the weekend. The cause of the problems remain to be found but that will be on the back burner as we get ready for Willow Springs in a mointh. I'll hit the Forum with the R-6 fault as a FYI when we find the problem.
  22. Hey Guys, I am no where as conversant in the uniqueness of Moto Guzzi and their different models. My affair really started with the fact that I just loved the sound they made. This and the family way the factory goes about their business. This said I have no idea what the tank came off of. Ed at Guzzi Power (he has been sponsoring the effort with quite a lot of help and bits) turned me loose on a stack of used tanks. I picked one that looked period correct circa Guzzi's best racing years. I had been thinking that it must be some kind of fuel level sensor. Because of the era
  23. Hello again, Sorry to only hit the forum when I need help but I do have another question. We are putting the last touches on our race bike and the paint is drying on the bodywork and tank (weather here in northern California is just right for this kind of work) The bike should be ready to head to Daytona with even some time for testing before we leave the left coast., So my question is this. We are using a tank that looks like it may be from the late '70's early '80's it does not have a built in pad and the fill pipe is centered. It is fitted for two fuel petcocks at the rear o
  24. Hello all, Sorry it took so long to get back but with the holidays and trying to get bikes ready.........Well time fly's. The real tricky part of wiring in the S-H coils is that the +/- marking is very small and very light. Took a magnifying glass that would have served Mr Holmes well to find the blood thing. The two posts form a "T" the up-right of the "T" is the positive the cross bar the negative. The + mark is on the out side of the coil on the rounded portion. Bikes are close to ready for testing and then off to Florida. Rich
  25. Hello to you all, Thought I'd give you folks an up date on the Manx Moto Guzzi project. Bike is just about ready to fit the full fairing (Airtech has helped with choosing one that fits) and then we'll paint everything. Once the fitting is finished we'll pull the bodywork back off for paint and take the machine to Mark Saliberg (Factory Pro. Tunning Northern California) to have the dyno work done. We are planning on racing our Yamaha R-6 in the 200 and if we can find a class we'll try and race the Guzzi on Sundays races. Last time at Daytona we had driven straight through fro
