I am thinking about getting an 200 yz 426. How is that compared to the '98 yz 4oo far as the weight and ease of starting. I am getting tired of the hard start. Also I always had good luck with you guys about getting tips on working on my 400, any body give me some advice on a '88 blaster, this I have a 1988 Yamaha Blaster the problem is that it was popping under load so it was rebuilt.I turned the pilot screw as the book states 1 and half turns out. The problem is now that it is hard to start when it does get going the engine starts to race up very fast where I have to kill it. With a little adjustment on the pilt screw the engine ran ok but stalls and I have to wait a little before starting it up What should I try next?
