I just put a K&N and white brothers pipe on my scrambler 500. I'm enjoying the power gains. I was wondering if I need to adjust the fuel mixture now that I have those mods. I also got a HSP clutch kit off of ebay and was wondering if you guys have any advice for installing it.

 

Hopefully someone with a W/B can confirm this, but I would say that you should be running a 160 main jet with the fuel mixture screw about 3 turns out from lightly seated. Did you clutch kit come with any instructions? If not, I think that HSP has instructions on their site. The primary springs and weights are pretty straight forward. For the secondary, you will need to pull it off. You will also need a friend to hold it still and push down on the helix so that you can get the snap ring off. You will need a good pari of snap ring pliers. Once you put the spring and helix in the correct postion, make sure you wind the clutch 1/3 turn, like the directions state. Then put the snap ring on. Also put a little bit of grease on the trans shaft in case you need to take the clutch off in the future.

 

Thats a affirm on the 160 although i think i have a 155 in mine right now i gotta go look. dang this racin stuff with the little man takin away from my time.
