As you will see, I'm really a newb at this and fairly clueless....Please bear w/me;
Trike engine drive sprocket rebuild - Got this 2.5 HF running fair but need to re-do sprocket gears. Could someone please explain what my best bet for gear ratio is on this. It now has a 10T #40 output sprocket at the MaxTorque clutch - goes to a 41T drive wheel sprocket. Doesn't have much power. Speed seems fair, after it gets going, but it takes quite a bit of pedaling to get it going in the first place. I think I'm burning up my clutch. And I'm told that's because my ratio is way off. And, if I'm not going to utilize some sort of jackshaft, I'll need a much larger drive wheel sprocket or I'll will burn up clutch. This is all very new and confusing to me.
I don't understand ratio's well enough or the jackshaft thing very well either. Is it that a jackshaft allows for a smoother transition of power because of having more sprockets progressively larger, as opposed to simply going from a small output sprocket to large drive wheel sprocket?
Looks like a big rebuild and re-design if I try to engineer a jackshaft into this...am I right? Can't I just install a bigger drive wheel sprocket? Like a 60T? Please, tell me I can! If my calcs are correct, (probably not), if I go from my existing 10T output sprocket to a 60T sprocket and change from existing 24" wheels, to 20", I get 6.0:1 ratio and at 3600 rpm = about 35mph. Is this right? And will this work? I like the 20" wheel idea for stability. The way it is now w/24", makes for unstable, high center of gravity - but that's a whole other topic...
If so, how should I attach it (new, big sprocket) to the drive wheel. Whoever attached the 40T that's on there now, didn't do it right, I don't think. Everything in that area is screwed up - bent, spokes and the sprocket wobbles too. It's a mess. Hope pics help explain. I need to order parts but not sure where to start. I really don't want to start tearing this thing apart until I'm more confident in what I'll find and what I'll need.
I've seen, like a sprocket kit for attaching drive-wheel sprocket to rear bicycle rear wheel (see atached jpg). But is there something similar for attaching a large 60T sprocket in this (trike) case?...and staying with the engine mounting as is?
Sorry for the long read hope it makes sense Thanks for looking!
Please see more pics....attached below. THANKS!
