rjdgriff Posted November 13, 2013 Report Share Posted November 13, 2013 Get better pipes and it will be a blast Quote Link to comment Share on other sites More sharing options...
bluebanshee98 Posted November 13, 2013 Report Share Posted November 13, 2013 True and weld crank. Buy the stock stroke cub cylinders for sale on here and get some CPI or shearer pipes. Pods timing plate Ect. Boom much better Quote Link to comment Share on other sites More sharing options...
Pastrykiller Posted November 13, 2013 Report Share Posted November 13, 2013 I have a play bike that is a stock stoke crank with drag ported stock cylinders. This thing flat out hauls the mail for what it is. Peaky and always provides a grin on your face if you ride it like you stole it. Quote Link to comment Share on other sites More sharing options...
camatv Posted November 15, 2013 Report Share Posted November 15, 2013 welded crank, better main bearings, billet basket with clutch upgrade. plus transmission upgrade is a must. at least if i built it it would be... Quote Link to comment Share on other sites More sharing options...
rjdgriff Posted November 15, 2013 Report Share Posted November 15, 2013 I ran an all stock tranny on my 421 serval with no problems at all Quote Link to comment Share on other sites More sharing options...
camatv Posted November 20, 2013 Report Share Posted November 20, 2013 then why did you ask about getting the trans upgraded?? i'm sure there are peeps on here that say i ran my _______ ( random motor) with all stock clutch, trans, non welded crank, and completely stock bottom end and it was fine.. i know plenty of shops that never even recommend that stuff.. until after there are problems. i personally think there are more posts about failures from lack of a good build in this forum than any other. Almost EVERY issue in the help sections and --help me my ____ is fucked up! -- posts are results of cutting corners. almost all the others are maintenance related. or just plain ole shitty parts failures. ( hey SH it happens) of course this is my opinion.. i dont build unreliable crap... Quote Link to comment Share on other sites More sharing options...

I had asked you about it before because I was planning on a 10mil serval but since I just sent the motor with Cameron at the dunes I'm just having him do the tranny. With the 4mil serval it worked perfectly but I knew I would need to do something different for the 10 Quote Link to comment Share on other sites More sharing options...
