So after a few start ups, checking the timing and some decent revs we have a lot less smoke. It seems I was clearing out all the extra 2 stroke oil in the barrels on first start up so that’s a positive. I was not looking forward to rebuilding the crank.
Took it for a 20 mile shake down and it ran great but there were a few things I noticed.
For seal leak a lot haha so gotta change those. I have them, just need to install em.
And there is a little tick noise I am hearing under certain conditions. If you listen closely you may be able to pick it up. Kinda sounds like a ping but it’s not consistent enough. It almost has the consistency off water dripping from the faucet and kind of comes and goes.
It may be something crackling in the left exhaust although I’m not sure. More investigation is needed.
Trying to keep the revs down under 5k for the first few hundred miles. Been a while since I’ve broken in a cast 2stroke cylinder.
I installed cylinder head temp gauges on both heads and while it may be too late to notice a real problem by the time the heads change temps drastically I did get good consistent temp reading around 250-275f with 10 or so degrees between sides so that was nice to see.
