Aftermarket cylinders

[TideFan]

I was just looking at aftermarket cylinders to see if any help out the low end but they all seem to be more geared for duning and drag racing. However, I did run across these old ones. Anybody ever use or seen someone with the FMF powervalve cylinders? Here is a press release on avtsource, looks like around 2000. http://www.atvsource.com/articles/press_releases/2000/121900_fmf_powervalve.htm

thoes are trex cylinders.from what ive read they are a pita to get them running right, your better off with a cheetah or cub

What are you planning on doing with your bike? I would consider doing a 4 mil and port to gain low end.

Well it will be a while before I do anything. It is still all stock right now. I was just looking around to see what kind of options there is for when I do make upgrades. I was thinking that going 4 mil with ported stock cylinders was probably my best option. I just don't want to kill what low end it has now and an increase would be nice. Not any sand dunes in Alabama to run around wide open on all the time. First I need to get some pipes. I bought it new in 06 (its a 2005 model) and it might have 10 hours on it, but I'm planning on getting some riding time in this year.

get some pro-circuits first, boysen power or pro reeds to start. when you go to build, run a 4mill woods port. you can pick up a coolhead, too, and advanced timing really helps out alot. i like +5.5, but most start with +4. don't go crqazy on the carbs either- the stock size can hang in there pretty damn good, but have water issues, so 28mm-30mm carbs would be fine, but bigger than that, you will pull teeth to get decent lowend out of them. the closest pv cyls to having good lowend is the rz setup, but they all pretty much just add a litlle mid-low to dune to drag port cyls
