I just installed a moose air filter, aftermarket reeds, and a fmf pipe. I've been told that I need to re-ject my carb and have no idea how to do this. Can someone point in the right direction with some advice or a website. My carb is stock and my engine has been bored once up. Right now I am having a major problem. I took my blaster to the track with these parts installed and got 3/4 around the track and when I slowed down it died. After kicking a few times and giving it some gas, which has never been needed, it started and died. I finally got it running and cautiously drove it to my truck and it died again. While I was on the track I noticed some gas leaking from the carb which I believe it was coming from the overspill line from the float bowl. I brought it home and installed the stock reeds. I started it and it ran ok and then it starting puttering and died like it did with the aftermarket reeds. Now it won't start, I checked the spark plug and it was pretty dark. I think that it may just be the spark plug, but I have some doubts. How can I tell if I have good compression if I don't have a guage? I'm going to reinstall the aftermarket reeds and re-jet as soon as I find out how this is done. If you have any advice please send it my way ASAP! Thanks

 

I got the FMF Fatty pipes with PC2 Silencer, and yes you will have to rejet. Sounds like you may be fouling plugs. Im still learning all this quad engine work myself and have learned quite a bit now. Rejetting isnt that hard but If you have never done it before you will prolly need specific instructions. A good person to email and ask for instructs would be at this url http://my.voyager.net/blaster125/
he is pretty experienced with the blasters.
Or you could ask your local yamaha shop.
Hope this helps.
