tremor38,
Do you have any other information on the "Beet Japan" product line? I'm interested in their "315" kit.
Where are you located at? I'm kind of liking the screen name - is that indicative of the tremors that happen in Japan all the time?

Beet Japan Products
The above link is all in Japanese. They have a section labeled 'English' but when you click on it all you get is a message saying "coming soon."
This stuff is pretty pricey. Here are few of the items translated to give you an idea.
-315cc cylinder, pistion, rings, clips an pin are 83,790 yen or about $710.00 U.S.
-The cams are 42,000 yen or about $355.00 U.S. (315cc kit+cams=$1065.00 U.S.)
A 4.5 inch 7 row oil cooler is 43,890 or about $372 U.S.
Sorry about the wrong info I gave you earlier; the cams are not included in the price of the big bore kit.
Another thing to consider when adding cams is that they have no KACR. According to some people that is a blessing, but I'd rather not have the starter motor labor excessively to turn over the engine. Also, hot starting is a bit easier with the KACR.

Depending on which way you go with cams, that may or NOT be a problem. Some cams diminish "effective compression ratios" by not closing the intake valve until after BDC. Those cams usually need a boost in static compression ratio to have any bottom end power. Of course they work really well after about 8000 rpms.
I'm looking to build the motor for a powerband from 4000 to 8000 rpms. At present, my "sweet spot" seems to be right at 6000 rpms. The bike just sounds "happy" running there.
