kaw rider:
bdi
the aux exhaust ports short cycle. but that wouldn't be a problem intill kips open up. look at the picture i posted with the kips drum. what looks different with it.
BDI:
Well you successfuly got me confused. If your talking about the fact that the kips drums dont uncover the secondary exhaust ports completely thats a easy fix just a little grinding fixes that. I dont get what you mean by short cycle.
kaw rider:
can somebody post a picture of a oem cast piston.
BDI:
I have ben in the shop playing with a piston and cylinder to try and figure out what you are talking about. If you are talking about the cut out on the side of the piston causing the secondary exhauste port and the forward transfer port to overlap I think that is one of those two stroke things that you can't do anything about. :|
kaw rider:
yes you did find it. yes there is a fix. weld up both port around 1.5mm narrower. i do that done when have many other things welded on the cylinder at the same time. i done it on my current cylinder.
