dajogejr Posted January 21, 2009 Report Posted January 21, 2009 Just saw this for the first time... NO, I'm perfectly happy with my Chariot product. just curious as to if anyone has seen/used one. http://cgi.ebay.com/ebaymotors/Yamaha-YFZ3...sQ5fAccessories Quote
dragbanshee Posted January 21, 2009 Report Posted January 21, 2009 Never seen that one before, and dont think I like the way its set up. Quote
Bansh-eman Posted January 21, 2009 Report Posted January 21, 2009 humm never seen this before. Looks like they modified a YZ250 coolhead design and added a heatsink type precooler. Not something that really draws me in. :shrug: edit: oh and it looks like you have to use thier domes rather then your run of the mill noss/pro design style domes Quote
dajogejr Posted January 21, 2009 Author Report Posted January 21, 2009 First I've seen of it...can't say the mini radiator at the back of the head impresses me. Then again, I run a boost bottle..it might get in the way... Quote
2001Stroker Posted January 21, 2009 Report Posted January 21, 2009 Yea, I seen that a few weeks ago. Someone was asking input about it on HillClimbersForum. I didn't think it would be a good idea having one for trail riding, since mud could get caked up in it. Mud tends to hold heat, and that could possibly make it overheat. Quote
shanYE west Posted January 21, 2009 Report Posted January 21, 2009 looks similar to the rhino heads.. Quote
FireHead Posted January 21, 2009 Report Posted January 21, 2009 It seems to me that there is no reason for the additional parts count......... Beyond that, you might lose some thermodynamic efficiency (trasferring heat to the coolant) with all of the hoses and non-functional fins that are going on there. :geek: Quote
lowbuckracing Posted January 21, 2009 Report Posted January 21, 2009 Ive ran a prototyype for the 250r atc for him...he is a awesome machinist in moreno valley....All his domes are interchangable also....He does motor porting as well,nice guy.He likes doing the single head for each one so you dont have a uneven surface when you tighten it up....

kbone77 Posted January 21, 2009 Report Posted January 21, 2009 seems as though a single head would be stronger, when one piston is compressing and firing the stress is spread across both jugs, not just the one. if the deck heights aren't the same as mentioned in the previous post-you'd have bigger problems, the compression and port timings wouldn't be identical.. with my experience so far w/ heads, my original stock/milled head was my favorite.. that one head gasket was simpler then all the o-rings i'm f'ing with now on my cool head..

regalrocket Posted January 21, 2009 Report Posted January 21, 2009 (edited) I do like the seperate head design personally. I am not a fan of the goofy "precooler". A simple manifold or hose connections would have been fine for me. Edited January 21, 2009 by regalrocket Quote
njbanshee Posted January 21, 2009 Report Posted January 21, 2009 I don't like it. I think one solid piece would work best. Quote
dlnoss Posted January 22, 2009 Report Posted January 22, 2009 I'm not slamming it. It's kind of cool looking except for the finned part. If it does use standard size domes, I don't see how it would work with a Cub or other 68mm bore because it doesn't 'contain' the entire base of the dome. I've seen the Phat heads before for small 2-stroke bikes. -David Quote
locogato11283 Posted January 22, 2009 Report Posted January 22, 2009 i dont like it. it looks weird. too many fuckin parts. i like my NOSS way better. Quote
