Oh yes that is some serious kit ! Beautiful. Thanks for linking to that article. It would be a dream to ride one of those just for a few laps, but I could never do it justice. 😁 Brian

My pipes arrived in the mail yesterday, approx. 10 days after ordering. I'll unpack 'em this weekend..... can't wait. Brian

I heard that COTA (in my backyard) is getting re-paved. It is a great track. Brian

Captain, would you point me towards a Keihin carburetor jet source, please? Brian

Please fire off a flare when this beautiful left-side exhaust is avail for 4th Gen ! I want one...... maybe two. Brian

Measure the o-rings and just buy them from McMaster Carr or a local o-ring shop. I choose Viton when possible to resist alcohol corrosion.

I know how you broke the scaphoid bone !! It is so difficult to learn to fall with a closed fist. Get well soon ! Brian

My last motorcycle periodical was Sport Rider way, way back in the day when Nick Ienatsch was the editor. When they fired Nick, they lost me as a subscriber. I am enjoying Roadracing News of late... Brian

Check with Joe at V4Dreams.com. He is a wizard at restoration. Brian

Well Ken, I believe that you are very much mistaken then. Nope, I definitely mean "ethanol" (aka 'ethyl alcohol'). Methanol is a bit too poisonous for me, plus, I can distill my own fuel (eventually). Yes, less caloric value PER EQUAL MASS, but you have to use more ethanol than gasoline (air/fuel ratio), so ACTUALLY, you make MORE horsepower. Yeah, most people "wouldn't" because they don't really understand the benefits (cleaner burning, more power, environment, maybe less expensive, cooler burning, much higher octane), but yes, the mileage MAY decrease a small amount. I'm pursuing it for the POWER. We get an 85% ethanol blend here, so it is available (maybe add "availability" to the drawback list). Did you know that our Indy Car racing series uses E85? They certainly make plenty of power. Also drag racers like it. The high (14:1 maybe 15:1) compression pistons take advantage of the high octane and greatly increase the mechanical efficiency (power). Yes, there are certainly risks to excessive speed (shame you have such a repressive government, us too. ), but the extra power also translates to quicker acceleration. You understand all of that as you want to overbore and change camshafts for more power. On to fairings, yes, there are some European manufacturers and THOSE would probably be cost prohibitive for ME. Understood, we'll pick the best 'local' sources. Are you going to paint or use vinyl graphics? A while ago, I saw a French graphics company had made an RC45 fairing decal, but I can't locate that company now. Decals would be easier/cheaper/more accurate than paint for me. I need to find a spare engine to fool ('fuel'?) around with before I tear into mine, but the fairings s/b much sooner if I can find that decal. My timeframe is probably a year or 2 on the engine plans. Brian

Ken, I, too, have the urge to make a faux RC45 from my '97. Focusing on the graphics; got any leads on vinyl graphics? I'm leaning towards Beasley Composites for the fairings. Thanks for the Mohawk camshaft lead; I'm thinking of custom high-compression pistons and ethanol, so different cams are possible. Pictures when able? Brian

Fastdruid, I'm curious about your special note of E85. Have you run such? If so, I realize this is a carburetion discussion, but did you make any other optimization changes (higher compression/boost)? VERY interesting topic (retrofitting FI to older VFR's) and I agree that it is probably the better way to go for those with increasingly complex modifications (E85). Please, keep this thread going ! -Smack-

I would like 2 sets, please. Anyone got an electronic manual for these Keihin carburetors that discusses jet sizes etc.? I have the '96 shop manual. Any idea if these diaphragms are the same size as used in the '86 750? Thanks for putting this idea together !
