I bought a 2001 DS650 and it runs great. I love how big it is and the way it handles. However, mine is very slow. I see people talking about it keeping up with raptors and yfz450s and what not but theres no way mine would even come close. My question is, what can I do to help it gain some speed? I was told a fuel programmer but I know nothing about them. I know a pipe and rejetting would help, so what pipe do yall recommend? Thanks for your help everyone.

 

Anybody able to help out? I'm not good on the technical side of things.
