Britt, like I told you on the phone I really believe that the transfer ports are a much better idea. I dont think spraying the skirt with sub zero nitrous is a good idea!! I hope that bore scoring is from the trashed reeds and not your lazy air filter skills. Better check those bottom end rod/main bearings...

The bottom end feels fine.
About 3 months ago I found a hole in my airfilter (bettery rubbed through) and it sucked some sand but seemed fine, I think it trashed the bore tho![Sad :(](./images/smilies/icon_sad.gif)

sand doesn't just pass through a bottomend, it chills there for a while and grinds shit up!

those are dual stage reeds, and both the inner and outer reeds should sit shut and be able to open.aloha450x wrote:they sit flat but are both of them supposed to open? the petals and the part they sit on?

i dont see any reason you would get a performance gain, but spraying it into the transfer would be a better idea i think because it wont directly hit your reeds and side of the piston. there is a guy in phoenix that built a cr500 for drag racing that held a single cylinder speed record for a while, he sprayed into the transfer, you might check into tapping the transfers brit

Where though? The reed block takes up most of the space in the cast part of the intake.

A side from the cracks. When I had to replace the base gasket, my intake side looked the same, in that there is a lot of ware about an inch to either side from the center line. Almost looks like a crack on each side but not. Its obvious that the center of the piston isn't touching anything. Why is this? Glen, anyone.britincali wrote:I guess the 30 shot killed her![]()

I have said it before and ill say it again, (even if Bob thinks im retarded) the cool intake fuel air charge highly cools that part of the piston. This is why I beleive the cracks always form on the intake side right where Britts cracked. This also explains the lack of wear do to "shrinkage". When was the last time you saw the exhaust side cracked??

Ive ran more N20 through cast piston motors than I care to think about... ZERO failures.M.F.D.B. wrote:
Cast piston would have lasted about 1/3 as long as this Wiseco did, at BEST...
( Horsepower per CC was less though...)
I would run a 15 horse jet on one.
Cast would work with a wet kit, Boondocker, no way.

ya, cast would work, but if brits were cast, frags would have blown holes in the cases and ended up sitting in the sand!
I don't like losing piston peices on the ground...that really messes up a day of riding.
