BTW, I've got a complete set of black excells, buchanan heavy duty spokes, yamaha hubs, pivot works bearings, etc. to make a complete pair. I'll sell them as a kit or laced up and ready to go, your choice. send me an email address and I'll forward some pics.

    262 kit and AMA rules?

    That's why I took the overbore pistons/kits out of my boy's bikes and went back to stock bore. By the way, you can check them out for sale at the "Auction site" http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=4559535204&rd=1&sspagename=STRK%3AMESE%3AIT&rd=1 http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=4559538828&rd=1&sspagename=STRK%3AMESE%3AIT&rd=1

    Ron Woods Intake Dyno! Terrible!!!

    LOL!!! I'm sorry if I misinterpreted your statement, but knowing you.....I don't think so! Anyway, has anyone hooked up an EGT about 1.5-2" off the exhaust port exit and matched it with an air/fuel number? Just a thought......

    Wiseco High Comp Pistons??

    I ran the Wiseco high compression 97mm in my son's '03 450 all last year with no issues. Took it apart and it looks like it's ready for more (needs rings is all) pin bore & wrist pin are fine too along with no damage to crank or piston skirts.. JE makes a great piston as well.By the way, the Honda "05 can use the '04 piston if you relieve it to clear the piston squirter (Hmmn, would the Wiseco also clear the crank if it would have been relieved/checked? ) Is CP currently making any dirt bike pistons? They will/should be good also. Vertex should be real good too, although I currently have no experience with their products. By the way, with the 97mm high comp Wiseco, Hot Cams, ported head & Full titanium Jardine system it made 53 rear wheel HP.

    You can try or do a couple of things. Yes you could "double up" the base gasket, or better yet get an aluminum shim style base gasket of the correct/needed thickness. Are you running the OEM Yamaha gaskets or Cometic? I've seen a difference with them "squishing". Or, you can trim the lid of the piston the necessary amount and run the base gasket you have (that's what I do). If it's only knocking at idele and runs well, I'd be surprised if you don't find light contact between the head and piston. By the way, you may find it only hits on a side (left or right) which could warrant an inspection of crankcase to cylinder and crankshaft all being "true to the world". Good luck and keep looking, I'm pretty confident with Wiseco pistons (JEs Too!).

    JE Hi Comp... which ring?

    Use the "gold" one with the "silver face" , the "black" one is the second (scraper) ring when you have a conventional 3 ring stack.

    How does "rg" always seem to want to participate like this ? Is he crying for help ? Does he want to "come out" ? Let's get back to the motorcycles

    If it were me, I would take a real good look at the top of that piston and the deck of the head. You may be surprised to find that you have some contact there (is it the high compression piston?). I really doubt you'll hear an audible knock with a piston @ .004 versus .0015/.003. Especially after it warms up (that piston will seek out the cylinder wall). But you will hear the contact of a piston contacting the head (even lightly) or if you have the high compression piston and the air/fuel/spark is incorrect and it's detonating. I'd look beyond the piston a little bit further. Just my opinion amd some experience, "been there done that".
