I have an axle mounted LSD G43 on my current bike.
I have a Flowsystem tuned pipe for this motor but can't mount it, where the motor is positioned it would be hanging off the left side considerably. I can just see myself smacking a pedestrian with it or something else and snapping the pipe/mounts or even the topend!
This is my motor on a GSR goped BTW.
If I move the motor to a rack I can have some new pipe mount tabs welded on and use it "fingers crossed" the topend has to be flipped to mount the pipe on a goped. I've since put it back to stock because my trans reverses rotation and the air filter/exhaust would've been backwards
My concept is this, fabricate a beefy rear rack for engine mounting. Find a splined #41 6t sprocket to fit my 5:1 trans and drive the 7spd cluster off engine power with the biggest best quality chain that's going to fit the derailer. The derailer may work as is, or may need repositioning IDK yet this is all in the planning stages.
My rear rim is a dual drive so the pedal power will be moved to LSD in a single speed, "geared high so I can pedal assist at higher speeds" as it is I can't assist past 15-18 mph. That doesn't suit my needs, I have had this single speed setup up to 50 mph "5:1 trans-11t pinion-44t drive and 4+hp" on a straight flat run.
Even if I leave my bike single speed I want higher pedal gearing. I guess my best bet is to increase the crank sprocket size instead of changing gear clusters?
If I do build the shifter I'll use a 16t on the left side drive hub and a bit smaller crank sprocket than I would have setup as a single speed? I'll have to get it together to test some gearing options and see what works best for me.
