[QUOTE="Bill Thomas, post: 105127, member: 485"] Hello Tim, I have been having a read up, Not like me !. With the high first gear, 55 mph = 5,000 rev's. With the low first gear, 44 mph = 5,000 rev's. So you can see, If you have the high one 27.5 mph = 2,500 rev's, That's near to your 30 mph ?. I think a twin should run nice at about 2,000 rev's, or lower ?, Which comes back to I think the Carb's or ign' are not spot on, As Albervin says, A lot of people put a 48 rear sprocket on, Which is cheap and easy to do. Cheers Bill. [/QUOTE]
