Tungsten Posted February 10, 2004 Report Share Posted February 10, 2004 I plan on porting my cylinders and I wanted to know if I need to hone them after I do this? I am going to buy the kit with the templets.... I also plan on porting the reed cages, +4 on the timing and a Noss head with 20cc domes. Is this going to be okay on the stock crank and pump gas? Right now my bikes is stock other then Pro Circuit pipes and a 2 into air filter. Thanks Jeff Quote Link to comment Share on other sites More sharing options...
Indubitably Posted February 10, 2004 Report Share Posted February 10, 2004 You should be good, but I would recomend you getting your crank welded just so you know it won't go out and ruin other stuff. Quote Link to comment Share on other sites More sharing options...
Just for fun Posted February 10, 2004 Report Share Posted February 10, 2004 While your puttin around and porting your jugs and cages I would get the crank welded. By the time its done you'll be as well and if anything you'll have piece of mind that your crank wont seperate and grenade your new port work and pistons/top end.

rebelbanshee2 Posted February 10, 2004 Report Share Posted February 10, 2004 20cc seems like too much on pump. id go with 21s. get that crank welded!! especially if its the original from 87. mine separated a ton. Quote Link to comment Share on other sites More sharing options...
Tungsten Posted February 10, 2004 Author Report Share Posted February 10, 2004 Thanks for the info guys, Whats it cost to have the crank welded? Quote Link to comment Share on other sites More sharing options...
Leadfoot350 Posted February 10, 2004 Report Share Posted February 10, 2004 I dont think you will be able to get away with +4 timming and 20cc domes. you can always mix a ratio of race gas. Quote Link to comment Share on other sites More sharing options...
bkabina Posted February 11, 2004 Report Share Posted February 11, 2004 After you port it your gonna need to chamfer the ports again to make sure the rings don't get caught,and then give em a light hone,that will get rid of any burs that may be left from the chamfering.You need to hone it anyway to brake the glaze and make sure you get proper ring seat.

96shee84z28 Posted February 12, 2004 Report Share Posted February 12, 2004 if you get the 20cc domes do not run pump gas. i learned the hard way that pistons with end up with a big hole in the middle after a few rides. Quote Link to comment Share on other sites More sharing options...
shee4202 Posted February 13, 2004 Report Share Posted February 13, 2004 I just recently bought a cool head for my shee and i was told that stock is 23 and the guy told me to put 21 in there and it runs great. I just got done tearing the motor down and the pistons looked good. he told me that when i go to get it ported that i should move down to 19.
