Hi All,
As some of you may know, I have been having some trouble with my Mach Z. For those of you who don't know, basically I have been fouling a lot of plugs (mainly in the center cylinder), and there was a bit of a skip when going over bumps and sharp corners.
Anyway, I took it to the shop and they were able to fix the skipping problem 100% (although I haven't ridden it yet to see). They said it was caused by a bunch of bare wires underneath the motor (see my post "What do you think is wrong" for more info on this).
The problem is that it didn't solve the spark plug fouling problem. It appeared to at first, but they took it out later on yesterday and blew two plugs in the center cylinder. Anyway, the shop owner talked to another guy that had a Mach and he said that he runs BR8ES plugs in the center cylinder. He also talked to a mechanic from Al's Snowmobile Parts Warehouse (some of you may recognize that place), and that guy also said to run an "8" in the center cylinder.
So he put a new BR8ES plug in the center and they took it for a ride. They put on 60 miles with that plug and it never fouled.
I have heard a lot of people say not to change the heat range of the plug that you are using....what do you think about this case?
Also, I should point out that the temperature yesterday was in the mid 40's. Maybe that had something to do with it also.
Thanks for the help.
