There are two types of Mikuni round jets....one round jet is bigger than the other....one is very small and thats the one you need.

 

You can also go to Jets R Us and they have jet kits for just under $35. Or individual main jets for 3.09 They also have the new screws for the bowl and pilot jets. What ever you need at pretty good prices. FYI.

 

520 chain picked up 6 mph top speed.Nice Mod.

 

Keith i did not get my clutch yet.I also have a Vortex on its way and i will soon be stepping my compression up as well.I will be adding a drag axle before the spring so with a lighter pilot than me i should have a real runner.

 

So do i simply install the new jet or is there some tweaking involved?

 

Yep just take out the old one and put the new one in. Just don't put them in the wrong hole. It will not run right guaranteed.[img]i/expressions/face-icon-small-wink.gif[/img]

 

ILOVELAMP, Ive found some sprockets in my left overs box. Ive got a 15, 16 front and a 40 rear. All my rides are 520 now so I dont need them. If you want them PM me your address and I'll ship'em out to you.

 

Scatterbrain, heu man thanks for the offer but i already ordered a pair of RM they were only like 7.99 But thanks anyways.

 

When i took apart the carb there were some springs that came out and now i dont know where they came from. i know the big one is for the slide, and then there is a <u>really small</u> one that i dont know where it goes. and then there is a medium sized one and there is another one thats kind of rusty so it makes me think it was on the outside any ideas?
