well I put the white spring in my primary on the 250 as advised and like what it did. Now which color spring should I put in my 400 to get same results?? thanks

 

Well since the white spring is stock on a 400 TB try either a Polaris green or yellow.The yellow will give you more rpms on topend but the green wont engage as high.

 

I'd try the yellow. The green has just a little more stall than the white, after that they both have almost identicle shift rates.

 

Thanks guys I think I'll try both.

 

The green and yellow are much different in the higher shift rates. The yellow is 44-185 the green is 42-142. So the yellow will have alot more top rpm's.

 

I put an orange one in my scrambler 400 with an hpd pipe and a RcR silencer. Will take it out tomorrow for the first hard run.

 

my 400 came with the white. I have ran the epi orange and polaris yellow.

to be quite honest when I made the change to the EPI orange to the yellow it seemed alot faster. I gained some top end even though it over shoots the power mark. The EPI orange is about perfect for a tame all out stock pipe setup.

I took the yellow out on the advisement of many of the clutch guru's in here. Also EPI has a yellow of there own. 95 engagement 145 shift.

 

I have a question about the orange spring. Just messing around in the yard I have noticed that I have to get on the throttle almost a 1/4 before I feel the belt grip and move the tires. Is this normal with the orange spring or am I going to have tranny problems soon?

which orange do you mean, polaris orange or epi?

im running the epi, I think it would be to low for the hpd pipe you have.

whats your clutching setup for that pipe by the way?

 

Anytime you change the primary spring to a more agressive one it will take more throttle to get it to move. Good for racing, fast trail riding but bad for rocks and slow technical stuff.
