I just received my White Bros. R-4 slip on for my DS. I need to know what size (number) the stock main jet is so that I have an idea of what size I need with the new exhaust.

Thanks in advance.

I think its like a 165. ???? Don't spend the money on the dyno jet kit ,just save it for the carb kit. You will be money ahead.

I was just going to try a bigger main jet. No Dyno Jet kit. Actually, have to save money for the Banshee kit. Oops, did I just let the cat out of the bag?!

 

seems 170 -180 works with the pipe.

 

Daren, when did you get a DS?

 

main jets are $2 each - the money you pay for a dynojet kit has nothing to do with the assortment of jets in it, you're paying for the r&d that went into the design of the superior needle they come with. if you want a smoother power curve get it, if not then just get a few mikuni mains.

 

Matt,

Bought the DS about 2 months ago. Are you shocked?? I sold the Banshee shortly after. Really shocked now?? I like the DS a lot, but I'm afraid that I may end up with another Banshee. The DS needs some company in the garage!!

I put a 170 main in it today. We'll see how it does. I just bought the 170 & 175 mains. Didn't want to spend the money for the Dynojet kit.

Thanks for all the replies.
