They'll sell kits to you, too.
are there any other places that sell jet kits for the later models? thanks
Drill out the air/fuel screw caps and set the screws to 2.5 turns out (may have to turn them out a little more for best tune) . Mine were set bad at the factory, from almost closed to two turns out. Set them all the same. Then get some washers from radio shack and shim the needles. I'd just get two #100 main jet and put them in 1 and four, two and three have 100's already. That will cost you about $20 for the two jets and bag of washers.Thats just my 2cents,....hope it helps
