I was wondering, I wanted to make my stock semiauto clutch engage at a little higher rpm on my 2001 wolverine. Will this give me back some of the low end bite I'm looking for? How do you drill it(size hole, where at, etc..) or how much does just putting heavy duty clutch springs accomplish?

I don't see any info yet Lucky 13. I don't have any either but am also interested. Would adjusting the increase- decrease control do anything to change when the clutch engages.

 

lucky i see in your signiture that you did end up buying the heavy duty cluth springs. How do they perfrom?

 

The clutch weight mod is a 3/16" hole drilled as near to the end of the weight shoe as possible, do NOT drill out the rivet hole, and use the first weight you drill as your template,use it to mark the spot on the other weights to make sure you put the hole on the same spot on every weight, to make sure the engagement is even. This will raise the rpm by about 400, makes a difference with bigger tires, and won't hurt top end.

 

Does this add a noticeable amount of low end for bigger tires. Also does this weaken them to where they could possibly break in the future.

 

i didn't do the clutch springs(it says valve springs). I'm trying to determine which will work better. If I drill the clutch weights, that should give some pretty good bite back, especially with stock size tires, shouldn't it?
let me know. Sounds like a lot of people are kinda interested in doing this mod.[img]i/expressions/face-icon-small-cool.gif[/img]

 

do you need any special tools to pull the clutch out to drill the shoes? Is there anything else I will need, gasket so that I can have everything at once? Is drill the clutch weight a hard mod to do? It doesn't sound bad.
