The deal is that it has little torque in 4th,lots of snort in 3rd,but 4th feels like mashed potatoes,as for 5th it's out of the question. There was a 33:11 final and I've switched to a 37:11 which gives me 11% more torque.This is a low mileage bike (18K) and dual plugged also put in a one notch higher main jet,a 50 idle jet and a notch down on the needle jet as I believed I was running rich in that range.All these mods have yet to be road tested being as I'm in Alaska and it's cold now.Question is: Anyone have similar experience with this engine with a sidecar.Like what to expect in in 4th and 5th speed torque wise.Thanks

You need to ask that question on the USCA forum WWW.sidecar.com There is a guy on that forum with almost the same rig and he is active enought to see your question.

Hi, I see that this is an older thread, but here is my experience. I have a R75/5 with a Dnepr sidecar. With the stock final drive I almost never got to use 4th gear, except on long down grades. I swapped to a final drive from a R60 and it did a little better, but then I found a R50 final drive and 4th gear is very usable, and a good match. I also have a Perry Bushong Sidecars triple tree that makes steering a whole lot easier.
