1320 Posted December 31, 2015 Posted December 31, 2015 My son is building his odysee and he is putting a chain drive on. He needs a large rear sprocket cause his new engine is a 6 speed. He also needs it to be for a 520 chain which I think most will be. His new engine is a crb250r....fuel injected and then turboed on e85. Anyways the mounting doesnt matter I have to fabricate that for him. He just needs something inthe high 40's low 50's cause I dont need him going 92 mph on the flats with a 42.... Quote
TIFFNAUB Posted December 31, 2015 Posted December 31, 2015 if you don't want it to have that much top end you need a small sprocket in the rear Quote
1320 Posted January 1, 2016 Author Posted January 1, 2016 Actually no, a smaller gear on the front or a bigger gear on the rear lowers your top speed. You can verify this by a goggle search....but ive been doing this for 30 years. Quote
