Sounds like you have a great machine. You will certainly notice a different between having 130psi and 165psi compression. But you may not need a rebuild yet, however, it wouldn't hurt to pull the head to check it out. Go through the whole thing, leak check it, tighten all the bolts, etc.

What are the best brands of piston to go with, I have seen wiseco kits listed.
I've probably bought 25-30 Wiseco pistons for my Quadracers and sleds and never once have I experienced a problem, missing part, or anything. Heck...I put the Wiseco "W" decal on my gage pod!
I got my last couple FL350 pistons from a website called Jawzy's Powersports. They sell 80-82.. FL350R kits for $149 shipped. And FL400R kits for $127 shipped.

Suprised to see you speak so highly about wiseco IMO they are junk, cheap knock offs, low quality POS they are "forged" all right a complete forgery.
They are made from a low silicon content alloy that makes them expand more than a OEM piston.
They use to have all kinds of problems with the locator pins falling out but they have seem to fixed this problem havent heard about one falling out in a while now but it still says in the instructions your suppose to check the pins before you install the rings to make sure they are not falling out, this is the only piston mfg in the world with these instructions and problems.
Wiseco gained is popularity years ago because they were cheaper than OEM now that the company that owns wiseco has bought out about every piston mfg in the world wiseco has raised their prices by about 50% to complement their monopoly.
At the same time they raised their prices 50% they also cut back on the machining of their pistons hold a OEM in one hand and a wiseco in the other you don't need a scale to weight them you can feel the difference they are way heavier than OEM.
I keep running into piston pin fitment problems and have to use a hammer to realign the piston pin bore their machining and quality control has went down the tubes about the exact same time they raised their prices by 50%
Wiseco pistons and rings also don't wear as long as OEM pistons this has been since day one and well documented by
Engine builders world wide.
You have to run more piston to cylinder clearance with a wiseco this means less power due to the piston rocking, the rocking of the piston causes the rings to scrub the cylinder wall more at TDC (Top Dead Center) that's why you see more wear on the cylinder at the top.
Dealers LOVE them because the PROFIT margin is about double what they make off a OEM piston that's why they keep pushing them and stocking them and NOT stocking OEM pistons, most guys want the piston when they walk in and don't want to order one, win win for the dealers.
Cant count the times I have seen a wiseco owner blame himself when the wiseco (seizeco) seized up in their Engine then they replaced it and ran their jutting so rich (less HP) they would foul plugs and leave a trail of blue smoke every place they went.
I could type all day about these junk POS knockoffs here is a video I made of the piston pin.
http://www.youtube.com/profile?user=Pil ... iew=videosWhat REALLY sucks is now Honda stopped production on the OEM pistons were stuck with these shitty over priced POS low quality too heavy wiseco pistons.
Spend a day search the web you will find a endless supply of wiseco horror stories, after spending a day reading ask yourself why you don't find the same problems with the OEM pistons.
