My new set-up has some 'different' combinations to make a 760 DS. I sent my crank along with a +4mm stroker pin to Robertson cycle in Nebraska for modification. I sent a stock cylinder and a 105 bore sleeve along with a 105.5 Pami piston to Craycraft motors to mate. I ported and modified the combustion chamber to fit a Pami 12.0 to 1 piston. For cams I now have the .450 lift Woods set and gave away my .395 set to biggerisbetter. For carbs I am running a set of 40mm Lectron carbs setup for alcohol. For my pipe I am running mbrp headers into an HMF can. I also have a +4 swing arm to help keep it down. My Dynos on alcohol with .395 cams, 11.5 woods piston, the dual carbs on alcohol were 51hp. This was @ 17 to 1 air fuel which is super lean for alcohol. I had a power jet stuck closed thats why it went way lean, I didnt realize until to dyno time was up. I noticed an immediate gain once I fixed that. I think about 53-55hp. But with this new setup what do you think as far as hp#??? 300ft times? Tell me what you think? One more question; if you take 8 ounces out of the crank lobes and 8 ounces from the counterbalancer it should still equal out right?

I would not put it together without balancing the whole assembly.JMO Dynamic balance that is.

 

forget dyno numbers- every machine is different, IMO they are only good for tunning - sounds like you have a pretty hot set up - run it against other built bikes that's the real test. So how does it feel? I have had my bike on 2 different dynos, the difference was 20 hp[img]i/expressions/face-icon-small-shocked.gif[/img]

 

I think they were about 29 and 49 hp werent they major??? LMAO
