only do that if it's humid. it was very humid here last sat. your best bet is leave timing and jetting alone and take a little fuel pressure out of it. when its hot there is less oxygen in the air to burn so you need less fuel. try a 1/4lb check plugs and mph. depending on how hot it is probably take a 1/2lb away.

Fuel is the power, I wouldn`t take it away to clean it up.Just add more to the spread, ie: you run a 4 spread make it a 5 spread to clean it up.When there is less o2 in the air, put your own o2 in the engine.My .02.

Should`ve put a HookerMaxflow on there,any "chamber muffler" will hurt power a little.Tested aerchamber against maxflow`s years ago and they were quicker, and not to loud.

Bullets been on there for the last few years,wentfrom maxflows to bullets and got nothing in et,more noise and a little less weight.
