Yay! I could not figure this out. I am kinda looking for more of a mid range there are some steep hills in my hood but I don't wanna sacrifice too much on the flatsI think I have a shimano that is close to that I could swap in. I am looking forward to the centrifugal clutch (no more manual clutch) and it being watercooled! So cool. Cant wait to get it all put together and post that first picYay! Shift kit!
Your engine will LOVE you for it.
Use a 6t clutch sprocket.
Chain it to a 47t(#25h)jackshaft sprocket.
The 47t is 3.87" diameter, about the same as a 24t(#35) sprocket.
On the right side jackshaft, use a 9t(#35) Sick Bike Parts(SBP) sprocket.
Connect to a 36t outer chainring sprocket, freewheel and crank arm.
Use a 24t inner chainring SBP sprocket.
Your first gear(28t) ratio will be 36.56:1.
Your final gear will be 18.28:1.
38.1mph @ 9000rpm in 7th gear.
For more low gearing, swap in a 14-32 for 41.78:1 ratio.
You could literally climb trees with this stump pulling 1st gear.
