Haha I was just looking into that. I’m thinking of first trying to change the rear to 38T and keeping the front at 14 and hoping to get a little more at top end. As far as getting a bore kit. I only know one that works with rc42 and it is a lot of mixed parts and gets it to 815cc but I’m not...

well I believe a 1994 rc42 is supposed to go 125. Given her age regardless of work done to re do the engine I would expect her to go a bit less around 115 120 but now with the sprocket change to gain torque which is now 14-40 I would still like to gain top end without hurting the torque. She is...

Are there other ways to gain top end besides changing sprocket and losing acceleration?

Do you know of anyways to keep the top end high and still raise the torque?

Yes I believe it is running on 14 and 40. Do you think that would explain top end speed? Torque is definitely nice though.

Hi everyone. I have a custom cafe racer with a stock engine running on 135 Jets into stock carbs. Bike runs great but fifth gear she is basically maxing out at 80 so mph. The sprockets are not factory and I believe are smaller in front and back which gave it more acceleration but I don’t know...
