I just bought a pipe for my 01 scrambler 500 4x4 off of ebay, its has no stamp of the manufacturer on it but it looks like a super trap, I was wondering what size jet to run in the machine and any tips on what brands to buy and installation.


Thanks for your help

 

Should be able to run the stock jet which is a #155.It comes fat from the factory.I did the same thing and it worked ok.If anything you will have to lean it out.

 

I agree, alot of times with a pipe change on a 4 stroke a jet change is not necessary, not always, but most of the time.
