gunnin4elvis Posted August 8, 2017 Report Share Posted August 8, 2017 Hey all, a few yrs ago I built my bike pc by pc and I bought a clutch with heavy duty springs. I am rebuilding and I've got a lock up now. I want to use the lock up to do the work of the heavy springs rather than gorilla grip the clutch. What kind of springs are you runnin on a 421 to make this an easy day at the office? Thanks Quote Link to comment Share on other sites More sharing options...

trickedcarbine Posted August 8, 2017 Report Share Posted August 8, 2017 Six OEM or possibly the Barnett pack with 3 HD and 3 OE. Quote Link to comment Share on other sites More sharing options...

I don't have stock springs due to building pc by pc. I literally started with a chassis and empty set of cases. All the springs I'm finding are HD so obviously not looking in the right place. Any suggestions? Thanks Quote Link to comment Share on other sites More sharing options...

camatv Posted September 7, 2017 Report Share Posted September 7, 2017 if you buy stock springs they need tested height and spring rate. I have boxes of stocker springs they are all different heights. if you just have to have girly hands then buy all new stock springs. or use the 15% over that most kits come with 1 Quote Link to comment Share on other sites More sharing options...

Not critical for most guy's applications but if you're as anal about clutch tuning as I am for my asphalt bikes then dealing with variances in used springs is a real freakin treat lol.

trickedcarbine Posted September 12, 2017 Report Share Posted September 12, 2017 Special06 had a ton of clutch stuff a while back. Check the For Sale section to see if it's still there. Quote Link to comment Share on other sites More sharing options...
jlevasseur Posted November 8, 2017 Report Share Posted November 8, 2017 I think it depends on set up, rider weight and type of riding or racing.. I run half stock and half toomey springs in one of my cubs, with no added weight on the lock out. If you doing the track you can play with base pressure to achieve the best 60 ft, MPH and ET. Just my 02 cents Quote Link to comment Share on other sites More sharing options...
