Banshee launch issues

I've been somewhat disappointed ever since I checked compression after building it. Showed 130 new and 140 after 2 heat cycles. Maybe I don't know enough about all this yet but it seemed kinda low to me based on what I've read on here

I ran that for 10 gallons, the last mix was straight 93 once I came to my senses. I added the extra octane to combat the (at the time) 6 degree advance.

 

I have no issue mixing fuel to get what I need, just want to avoid going straight 110 on a trail bike

if you check your base gasket that will tell you if its the problem. the only way your getting that squish measurement with those dome specs is with a way to big base gasket. you can call 10 people or just go check it... lol

The hell with it, I'm busy the next 2 weekends so why not try to get it fixed now. I'll call Cam and get his opinion and see if he wants any other info and I'll tear into it tonight

So I asked him specifically about the quality of his crankshafts and he assured me that his cranks were fine, not saying that's the truth, and at this point I'm not backing him due to these issues. What I have is certainly not a HR crank

I changed his cylinders out for a set I ported,IMO every hjr set up I've ever tuned didn't effective pull gear hard, they rev quick just never went anywhere. I have diffrent porting principles I go by and his porting is too far hogged out an far gone for me to be happy with low compression and conservative squish. Now take that same design set it on kill with big compression, good fuel , + 7 or so timing and bigger carbs you might get to where you wanna be. . Surf can hook u up for sure if not hit me up . With my porting I shoot for a turbo effect when u get on the pipe like you just added another cylinder either way you might end up spending another 600 but you will shake when u get off the bike

I was going to give Kevin a call later on also and give him a chance to chime in before I go anywhere else. I'll always let the manufacturer of something try to fix an issue before I blast them. Not my style. If fresh gaskets and domes get it right, that's fine. From now on I'll go elsewhere though.
