Do you have to rejet when you up the compression. I have a 11.5:1 Piston and what would be some good rejetting tips?

Thanks

 

Anybody? I would like to know before I break in my new piston tomarrow.

I didnt even need new rings & pistons like my dealers said........the O-Ring in my intake swelled & wouldnt let any gas in.[img]i/expressions/face-icon-small-confused.gif[/img]

 

We are decking the head on my 703 this week which will raise the compression 1/2 -1 point and I was told that I may have to jet slightly higher so I would assume going from stock to 11.5/1 that you would need to also.

 

what elevation are you riding at? And are you running the stock carb? If you are below 3000 ft. I would go up just one step. Ride it then check the plugs. Don't look at the porcelin it is misleading, instead check the electrode. The closer the marking is to the tip, the richer it is, closer to the base the leaner it is. You want to be some what in the middle, but closer to the base side.
