I looked at getting the 3 with the adjustable leak jet, but got a good deal on the 2 on e-bay. Did't do much for my DRZ 400 bike. Followed the instructions and went with the stock settings on the accelerator pump, and upped the fuel screw a bit. Still have to raise the idle to help the low RPM flame out. If anyone has some imfo on better settings i'd like to hear from you.
I had a spark plug crap out on me in my raptor while warming it up. It was like someone flipped a switch, was running fine and just died. Try a new plug, even if it sparks outside the combustion chamber. Under compression can be a different story.
Well, one more to go! Big V pulled off the win this weekend, Bubba's officially done, crashed and burned while in the lead...again! Twelve points seperating Villapoto, Reed, and Dungey, should be a great finish in Vegas.
My guess is that it's not actually a "Suzuki" engine. Chinese branded ATV makers have been known to copy proven products, but use inferior materials in order to make them as cheaply as possible. They may look identical on the outside, but in reality are worlds apart in quality. Specs and tolerances are probably way off. Good luck with your search.
A good tire repair kit with tire plugs, patches, CO2 cartriges, tools, rubber cement can be bought in one convenient kit for fairly cheap. I've had to use mine more than once. Most valuable item in my opinion.
