AKheathen Posted June 27, 2009 Report Share Posted June 27, 2009 stockkers are between 22-25cc's, and .030 is the point where you will have to have the head re-chambered to prevent piston slap. coolheads don't really do much for cooling, but you can switch the domes to whatever you want. trust me, 21-20's will be fine on pump, and even smaller @ higher elevations. noss machine's website has a dome chart, if you don't believe me.

blanco25 Posted June 27, 2009 Report Share Posted June 27, 2009 the count down begins until you get a cub. 100,99,98,97 Quote Link to comment Share on other sites More sharing options...
Maul Posted June 27, 2009 Author Report Share Posted June 27, 2009 I got this bike with what looks to be shaved about .20 with that Im running about 140psi at 3500 feet. I do ride at sea level some times to and have never checked my comp there but seems to run fine on pump gas but maybe I'm pushing my limit there. What my plan is to put a cool head on this bike and put the shaved head onto my 88 when I get the cylinders back from being ported. Quote Link to comment Share on other sites More sharing options...
Maul Posted June 27, 2009 Author Report Share Posted June 27, 2009 the count down begins until you get a cub. 100,99,98,97 man you nailed that one one the head and if the funding was there i would have one now.

RILS Posted June 27, 2009 Report Share Posted June 27, 2009 (edited) man you nailed that one one the head and if the funding was there i would have one now. Anyone want to donate to the poor little white boy foundation. Ive got a set of ported stkers that overall run better then a cub in my opinion. They might not make the as big numbers but they dont rob your lowend either. They are for stk stroke they can be bought reasonable if somebody wants them. If I had to guess i would say they are making around 65-70hp with cpi or trinty pipes. Edited June 27, 2009 by RILS Quote Link to comment Share on other sites More sharing options...

Well thanks for the offer but I'm getting my cylinder ported right now for my bike but i'll keep you in mind if the wife wants to juice hers up a little more.

RILS Posted June 27, 2009 Report Share Posted June 27, 2009 (edited) what type of porting, who ported them?? what bore they on? and how much?? i am interested I dont remember the guys name that ported them they have something engraved on the side of them but ill have to look and see what it is the bore is 65mm and is very fresh but they have been sitting for a while so they would need a hone.If I remember right the exhaust is around 192 and the transfers are really opened up and raised too. The intake has been cleaned up pretty good as well. I was running these before the crank and cubs and these are a running set of jugs like i said i liked them better overall then the cub.

RILS Posted June 27, 2009 Report Share Posted June 27, 2009 so is it more of a drag port?? pistons included??? and price? maybe some pics.. lol Yea I guess u would call it a drag port the way they run on top but they have alot of lowend just pm me if ur interested and ive got a extra set of used wisecos ill throw in with them if u want.

toolman Posted June 27, 2009 Report Share Posted June 27, 2009 I was running 170psi on pump gas with a shaved head no problems. Pulled it apart for trans work and found the stock crank was coming apart. I just built one with a cool head and 19cc dome 180psi i will let you know tomorrow if it stays togather it has a welded crank. about 500 feet above sea level.

I don't think I was clear on what bike I'm thinking about the head for. I want to put a cool head on my wifes bike which is .80 over, stock porting and timing and put the head off of her bike which is shaved .20 onto mine when I get the jugs back from being ported Quote Link to comment Share on other sites More sharing options...
RILS Posted June 27, 2009 Report Share Posted June 27, 2009 (edited) hey no prob on the high jack you were still somewhat on topic Yall can do what u want but 145-150 is about the limit on pump any builder will tell u that as far as the porting goes it wont change it a whole bunch about 5psi at the most is what i seen. And if you are going to run it long especilly at high compression welding the crank is a must they are known to come apart. I would say 140-145 with 4 degress on the timing is about all I would go on pump. I may be wrong but if i remember right the stockers are 24cc and u gain about 10psi for each cc you drop.
