BuckeyeShee21 Posted April 20, 2013 Report Share Posted April 20, 2013 Have 10 mil cub. Was on gas, stock milled head .04 squish, 156 compression in both cylinders. Converting to Alky so I ordered a noss head from Jeff at fast and had him cut me domes. I wanted to be around 170 psi or so. He said I needed 25cc domes. ( also running +10 timing) put it all together...... 125 psi in each cylinder. Don't know what I should do. Its strictly 300 ft quad. Oh and the squish now is almost .07 Quote Link to comment Share on other sites More sharing options...
BANSHEE HP Posted April 20, 2013 Report Share Posted April 20, 2013 You'll have a tough time detonating that's forsure. Not sure what your elevation is but here in Michigan a 19-21cc dome will get you near or at 170. And for what its worth .040 is mighty tight, low .50's would be more on track Quote Link to comment Share on other sites More sharing options...
possum Posted April 20, 2013 Report Share Posted April 20, 2013 22cc domes gave me 165psi. Quote Link to comment Share on other sites More sharing options...

Yea I know .04 is a bit tight. but now I'm at .07. Elevation here is about 1100ft. I'll have to call him but he was dead set on giving me 25's because of my timing.

BuckeyeShee21 Posted April 20, 2013 Author Report Share Posted April 20, 2013 I understand without knowing port timings And such its hard to estimate where you are going to be at.... just don't understand why its so drastically low Quote Link to comment Share on other sites More sharing options...
possum Posted April 20, 2013 Report Share Posted April 20, 2013 wheres your porting timings at? Quote Link to comment Share on other sites More sharing options...
BuckeyeShee21 Posted April 20, 2013 Author Report Share Posted April 20, 2013 Honestly I'm not sure. I got the motor off a member on here. Motor was built by d&m racing in Arizona. They won't answer emails or return any of my calls. I ran the motor all last season... ran strong on gas. I understand I'm asking for answers and don't have all the info needed.

crazycracker520 Posted April 20, 2013 Report Share Posted April 20, 2013 I'm pretty shure D&M went tits up! At least that's what I heard! A little while back I noticed an awful lot of there bikes on CL. Also heard they built a bunch of grenades and that's what did them in! crazycracker Quote Link to comment Share on other sites More sharing options...

Jereme6655 Posted April 20, 2013 Report Share Posted April 20, 2013 im thinking jeff may have realized that +10 timing on gas is a hell of a lot of timing. Either way i'd say just give him a call and see what he says. Quote Link to comment Share on other sites More sharing options...
BuckeyeShee21 Posted April 20, 2013 Author Report Share Posted April 20, 2013 Yea I heard some bad things about d&m but this motor gave me about 50 strong passes or so last year. I know Jeff will set me straight. He's a damn good guy and his motors run strong. What's the lowest compression you guys heard of anyone running a cub on alky? This being my first time with alky that's why I want to experiment with a motor that's already been used a bit.... that way if something happens its not that big of a loss.
