 Re: Is there a clutch/sprocket combo available for 4 strokes?
The answer is yes, but you need a reduction of some sort to attain an approximate 18 or 19 to 1 at the rear wheel. Any centrifugal clutch that fits a 5/8" shafter will work, but they normally have 11 or 12 teeth meaning that the rear sprocket would approach 200 teeth without reduction.
Now, the reduction could be with a jackshaft. For instance, 10 tooth 40, then another 10 to about 48 would get you a little over 19 to 1...but think how much space that would take up. Now you see why they use gearboxes.
What gearbox did you have? Hoot or Grubee? Grubee is not perfect (none of them are), but it seems more reliable than the Hoot. Also, what went wrong with your gearbox?
Also Staton has an 18.75 to 1 gearbox and I'm sure that is quality piece. |
