you can advance your timing without buying a degree key. All you have to do is change your stator plate holes with a dremel or somthing.
pm me if you want the full details.

 

how the hell am i supposed to kno im gonna buy one though lol but i love my new filter it works great just take it easy going throgh the muddy stuff and ull be alright i have yet to have a problem with it, much quicker, longer gears, and hell of alot faster

 

Have the head shaved. I dont know how much you can shave it before you have to adjust the squish but you can probably take enough off to make a difference. Shouldnt cost more than about 40 to just have it shaved. If somone tells you more just have a local machine shop do it.

 

tryin to keep this thing goin any other suggestions?
