I like your RD btw.
if I was going to vintage track race, I think that would be in contention,
although I'm not sure what class they would stick you in :|
How are the reed valves, do they lay perfectly flat against the cage? Stock original, replaced to your knowledge or aftermarket?
… was a part that made a significant performance difference on my 2-strokes.

Oil is still by injection, or are you running pre-mix ? I remember the RD's as being pretty heavy smokers :|
Also having a difficult time keeping the front end down, when it hit the power-band on a modified RD350 :)
… I'd probably be scared to do a high speed wheelie on a skinny tired bike now, been riding the fat Pirelli on the MV too much lately ;)
?:I do you see any missing fenders that would cause problems with the seat soaking up water ?
No fender on top of the seat to stop rain falling straight onto it in a car park or on the highway in a thunderstorm.
You put your fenders on top of your seat, :rolleyes: no wonder you won't posts pics of your imaginary motorcycles.

Good points - as those are tricky on these older 2strokes from what I've learned. The specialty shop that did the work on this RD installed the banshee cages and reeds - which really crisped things up.

The oil is still injection - with everything seeming to mix well still. A bit of typical 2stroke smoke on choke and warmup - but it settles in cleanly - even under WOT.

I haven't pulled too many wheelies on that skinny tire either - especially while still in partial lean out of a canyon corner here in Colorado :eek:, I save that for my Italian flavors that share the stable currently with the RD ('14 MV F4 and '10 1198SP). I'm sure you're loving that F3 - great looking bike.
:shock: you let other people work on your reeds ! ;)

what brands of 2-stroke injection oil have you tried?
Nice! Might hurt the top speed a bit, and limit visibility in high-speed corners - but who cares, you at least have a nice-smelling dry seat........ right Wit?? lol
?:I what, no pedals ? , would never work.

2 of mine don't have a seat, that works really well if you have a really comfortable fender :)
