Maybe he is referring to the such large displacement, I mEan it would probably be almost impossible to get a KA to revv to such numbers like some sr16ve motors and Honda v-tec motors at like 10k rpm.

Both adam.

guy in the usa was regularly fracturing the snout of the crank running > 7800rpm. I don't think he bothered balancing it all properly though.

either way, for those sort of rpms or greater, a BC full counter weight crank is cheap insurance.

Ran into a bit of a problem, motor is mostly together but I ran into a problem with the timing chain guides and tensioners....

1. Timing chain guide on the left is too short and doesn't reach the tensioner, only thing I can do is use the SOHC chain guide as its way too long and can be cut down the excess as the backing still touches the guide in the right spot.

2. That guide as mentioned above, is a little too "fat" and covers one of the bolt holes for the oil cover by about 1 to 1.5mm, than again, I can just shave that the 1 or 1.5mm also.

What did sleepa do ?
