dajogejr Posted October 8, 2007 Report Posted October 8, 2007 I'm going to tread carefully here because I don't want to insult a very nice guy, good businessman and site supporter... I have never had good luck with an after market head on my 4 mil early last year, or my 10 mil this year. However...once I finally got my 4 mil sealed last year, it did run great without leaks for the last 3/4 of the season. My cub did have a dip in it on the deck surface last year (4 mil) and once that was fixed, still have stud leaking problems...got that fixed finally and it was good all year afterwards. This year, through my own fault...I didn't check compression or cc my domes before I built my 10 mil. Domes were too small...so I can't fault anyone but myself for popping o rings on my head early this year. However, before the bike was ever fired...it had sealing problems on the head... I drag race with a pretty large and regular crowd at our tracks, and several have commented to me they've had leaking problems too. Most of the guys I run with either run stock heads on their OEM motors and cubs. However...most of them don't post on HQ...they're over on PS. With a Cheetah or other cylinder (cubs and OEM excluded) you have no choice but to run an after market head due to stud location. As said...I've tried every way I know how to seal 'em, nothing pisses me off more than clamping the hoses on and having it leak water as soon as you pour it in. Not leak...but seep it out.... Quote
kawiking Posted October 8, 2007 Author Report Posted October 8, 2007 i have the k & t head ...... are the stock studs a pain in the ass to get out,and will i need to rejet ? Quote
dajogejr Posted October 8, 2007 Report Posted October 8, 2007 Luck of the draw...a stud removal tool, like any other specialty tool, always makes the job easier... Normally..with compression and timing changes you don't have to rejet.. HOWEVER.... As with any mod, a plug chop is a very good idea just to be safe...sometimes you may have to give it a little more fuel. Quote
RagunCajun Posted October 8, 2007 Report Posted October 8, 2007 My noss head works great. I only have one leak problem but that's due to MY mechanical error. I pinched it putting it on. Fixed it and now she runs like a champ. With so many happy customers of the noss head, i wouldnt use any other. Quote
RoostRocket Posted October 8, 2007 Report Posted October 8, 2007 i have run 3 heads a stocker milled a modquad and a prodesign... and i have to say that modquad one was a piece of shit. i had it for a week blew an o ring so changed them out everything was going good for a little while then the fucker blew another one. when i had my motor rebuilt the builder told me that they were junk and showed me the spurrs and defects in it. i have the pro design one now and have had it for 9 months or so with no problems its easy to change domes and very well built.

kawiking Posted October 8, 2007 Author Report Posted October 8, 2007 well i guess i'll throw in the 18's and see if i can get around the 165 lbs mark. Quote
XxMeltIcexX Posted October 8, 2007 Report Posted October 8, 2007 well i guess i'll throw in the 18's and see if i can get around the 165 lbs mark. Word. Im running 185 and all i can say is i hope it starts the first time, cause the blow back on that kickstarter the second kick hurts (If i'm wearing my sandles that is) Quote
dlnoss Posted October 9, 2007 Report Posted October 9, 2007 If anyone does have a leak problem (or any other problem), please give me a call. There is usually an easy fix. -David Quote
