Ok, I have some thoughts I would like some input on.
First those of you who removed the spark arrestor,
Did you check your jetting, and adjust the airscrews? and was it a noticeable increase in power?

Second those of you who took out the airbox restriction like I did, Did you adjust the carbs or anything? I felt a small increase in power, but did not have to adjust anything.

Third Has anyone went to a hotter plug yet?
If so what where the results?

Fourth I havent really looked a the tops of the carbs closely, So dont make fun of me when I ask, Is there a Balance Tube like on a Banshee, that could benefit from the addition of a Boost Bottle?

 

I cut out the plastic piece, and it made a little difference. I took the spark arrester out and it made a noticeable difference from third gear on up, the power justs hits and keeps on pulling. The plug looks good, i think it was jetted to rich form the dealer.

 

How did you end up pulling your spark arrestor? I tool of the chrome cover, then the bolt that goes up through the bottom of the spark arrestor, but it still wouldn't budge. I even tried hitting it out with a chisel around the flare where it joins up with the silencer, but no go. Any suggestions?

 

I didn't even take off the chrome end cap. Just remove the bottom bolt, then get a pair of pliers and a rag. I put the rag in the jaws of the pliers so i didn't mess the finish up on the spark arrester. Just grab the top lip and twist back and forth while pulling at the same time and it will come out. Hope this helps

 

So, after you took it out, how does it sound?

And have you checked to see how your plug is burning since you did it??
