G’day all, has been a while since my last update. After much fiddling with this cylinder kit I have finished up cutting a spacer to raise the cylinder to line up the bottom of the transfer ports with the top of the piston @ b.d.c. Having done that I had about 2.7mm machined off the top of the cylinder to keep it level with the piston @ t.d.c. The way it is currently, it is running ok though there is some bog over ¾ throttle but I think that will be sorted with correct jetting, (I hope). I am currently running a 130 jet so will try somewhere around 125 or 128.
I still feel there is a lot more to be had from this setup but I have yet to find out how. So, will continue playing with jetting and plug indexing, maybe even trying with more height adjusting of the cylinder.
I will try to put up two pics of the port maps, one with the cylinder as new and the other as the cylinder is now, they are not too good but you will get the idea. In the first pic the line through the ports approx. 1/3rd. the way up is the top of the piston at bottom dead centre, in the second pic. it is at the bottom of the ports.
It may take a couple of posts to get them up so please bear with me.
