Hi everybody, quick question. My DS burned down in a fire, I have a line on an 05 DS, and was wondering if my web 109 cams out of the burned down DS will give me any gain on a stock engine. My DS had a full TVI 720 engine in it. I haven't torn it apart yet, the head might be good, but I'm positive the cams are.

With the 109s, you are going to want a high compression piston as a min. They sacrifice a lot of bottem for the top end they gain.

 

I might be able to get my hands on a ron wood tm45. I had a vortex on the machine that burned down, should I go that route again or is there something else out there today? What compression piston would you reccomend using on a stock engine. I can't afford a big bore kit right now, but would like something that hits harder. I ran straight 110 race gas in my 720 so gas isn't a problem. In your opinion, what is the best exhaust system to run on these quads? I had a Trinity stage 4 on my 720, it sounded good but I wasn't real impressed with the power gains. I don't want a drag pipe so it will have to be a full system, just wondering what everybody's running. Thanks Guy's!

 

The Ron Woods full system is a good one I had one on my old bike and loved it.
