Yet another gearing question

<< < (4/10) > >>

sandblaster:
If you want to build a torque monster, do everything that Alex (Alward25) recommends and... Drop your port timing.
You will loose on the top but you will gain it on the bottom.
And, Alex and I are working on a special set of drum valves to get all that top end back and still keeping the major bottom end improvement from dropping the port timing. Sorry, they are not available yet but we are working on it.. sorta..

Also, get a 38mm Quad vent air striker... more instant throttle response throughout the rpm range, and 1 hp gain to the rear wheel.

I didn't re-read the entire thread but a woods pipe also helps out..

A auto clutch is also a cool woods option...

Of course there is also the big bore option  :-o

But pulling stumps and towing tracked vehicles out of mud holes isn't for everyone  :lol:

umberto:
Is anyone making an auto clutch for the 500 anymore?  I'm asking for a friend.  :-D

sandblaster:
I'd call Revloc..

umberto:
These guys have them, for $925.   :-o

I think I am going to try stock springs in mine.  I thought I was just going soft until Danger came over, tried my clutch, and said, "d**n, that is hard to use!".  It made me feel a little less girly.   :-D

Foxx4Beaver:
I have an FMF Woods pipe that's in really good shape, that I'll never use again 1980mcneil, if you're interested...just pay the shipping and it's yours.
