you just got the springs from kawi then?

it is easiest just to buy the springs from a kawie dealer and they are not expensive at all. I would go with a maroon primary(gives a little bit of stall but not much) and a red secondary. I had this combo and it worked great for my 29.5 outlaws but I ended up putting in Dalton's fully adjustable kit.

 

[jgonie]

a epi red secondary spring is the must and a maroon, almond or even stock primary will work, all depends how much stall you want, almond or maroon are both good choices

 

[4byrookie]

Depending on where your located I could sell you a red secondary for a good price. $15 for the spring and depending on where you are you could either pick it up or shipping wouldn't cost very much.

so is the almond the biggest prim spring or the maroon?

Here's a spring chart (a few years old, so missing some newer ones) from Nyroc:

Stock BF750 and BF650 primary spring 2.5"-2.25"-1.25" ....0-13-152 lbs

Stock BF secondary spring 2.5"-1.25" ....62-205 lbs.


A low 2.5" spring force makes the engagement RPM close to idle (converse for high 2.5" force). If you want to rock crawl, or maintain driveability, select a spring with a low 2.5" force. Select at higher 2.5" force to raise engagement RPM for racing or competition pulling.

A high 1.25" force raises the RPM at shiftout, which means you will be reving higher as you accelerate. If you have modified you machine to produce power at higher RPM's than stock, a higher 1.25" force spring will help you use that power.

RPM between engagement and shiftout is determined by the tension between engagement and shiftout.

Channging the clutch weights will also affect engagment RPM, Shiftout, and RPM inbetween. Ask the distibutor of weights and springs for recommendations. Do not be surprised if what you change does not do exactly what you though it would. Many people use a trial and error approach to this.
