this is my first snowmobile. i bought the sled and it had br9eya plugs in it. it was running lean with them plugs and popping. so i put br9es plugs in, and 142.5 main jets in per tech section. i did the head gasket mod. and now i am fouling plugs after about 100 miles on new ones. what are the actualy plugs that are suppose to be in there?
thanks
thanks
it should have the br9es plugs, but make sure the are solid top plugs. The eya's are just better at not fouling. Maxdlx

I just went through a similar problem and I switched to the EYA's. Haven't fouled one since.

just switched my 600 sxr over to br9eix. sled starts awesome now. used to foul about one set per week on startup and take 6 or 7 pulls to start. now its never been more than 2 pulls and havent foulded a set since

those plugs are very high quality, but you definately pay for them. As long as they perform well and dont foul, they are probably well worth it.
