I have a stock BF 750 with stock tires. I've added a Dyna CDI and a twin air filter. The jetting has been done per Kawasaki service bulletin. Is there a clutchkit out there that can give me more acceleration and topend via theses parameters. Thanks.

 

Top end primary clutch mod or send it to VFORCE John. Get a CDI, disconnect the compression brake fork, get you a V-force Primary clutch cover. Change your Primary spring to the Almond or Blue/Orange & let her Flip!!!

It will flip if you don't get off the gas in time!![img]i/expressions/face-icon-small-happy.gif[/img]

 

Already have the cdi and am hitting 72 mph. How much faster with clutch mod from V-Force John, and how much faster with clutch mod and springs. Where do I purchase thses springs and how much. Thanks.

Is there a clutchkit to make BF 750 faster?
Vforce john hangs out on the other forums, info on primary clutch mod also in tech tips on same forum, You can purchase clutch springs directly from EPI or any Dalton spring dealer for around $20 each. Dalton also sells the primary cover called an "Over-drive clutch cover" http://www.dyno4u.com www.rockymountainatv.com OEM and Aftermarket Parts, Call 1-800-646-7612 or 1-800-646-7741 ronayers.com http://atv.dnsalias.com http://kod.gotdns.com http://www.smellofdeath.com/lloydy/jetting.htm http://www.700v.com ://www.rittercycle.com (618) 644-3211 BASIC CLUTCH MACHINING. Make sure the clutch is fulling disasembled!!!!!!!!!!!!!!!!!!!!! Mill 0.060 off the bottom of the free sheave, install in a lathe the other sheave attached to the shaft also remove 0.060 from the bottom of the sheave. On the face plate remove 0.110 off the areas that touch the spider only make sure the face plate is installed in a dividing wheel to have the areas equaly removed to reduce unbalancing of the plate. Cut one degree included angle off the face of the sheaves. This helps to get rid of grooves in the sheave and helps to ramp up the belt that much faster. For the venturous people you can drill 1/2 inch holes 4 of them in the triangle area inbetween the mounting bolts of the face plate. Go with smaller holes if the swiss cheese look bothers you, lol. This is a basic machine job you could gain in the neighborhood of 5mph on a stock machine to 10mph on a modified engine Don't know if you have the replacement needles for your carbs. Some brutes weere lean from the factory, missed at low speed, needed fatter/richer needles. Getting your Brute Dyno tuned and getting the jetting, needles/needle height, Air-fuel ratio correct and your belt tight, clutch tuned to shift at/hold that Peak RPM is the ticket. Then comes new Elka Or Works Shocks and a good set of light 6-ply tires will transform yur quad into a VERY different
