blaster668 Posted February 10, 2007 Report Posted February 10, 2007 Ok guys, I'm building a 358 cub motor. I currently have FMF Fatties, I know these will not work that great on the cub. But I want to keep my CFM aluminum airbox, and I believe that neither the CPI or Shearer pipes will allow me to do this. Does anyone have suggestions? Quote
yamaha04 Posted February 10, 2007 Report Posted February 10, 2007 i think CPI will work my buddy ran an stock air box with his. i dont think shearas will work Quote
theshee Posted February 10, 2007 Report Posted February 10, 2007 I dont know what to say if you insist on keeping the airbox. I would ditch the airbox, get some nice pod style filters and run Shearers or CPI's. :thumbsup: Actually now that I think about it, my bros shee has CPIs and had the airbox till we took it off... I would just get some CPI's. Quote
blaster668 Posted February 10, 2007 Author Report Posted February 10, 2007 Also, here is a link that shows the cfm airbox and how it mounts. I need to keep the airbox for occasional water protection. http://cgi.ebay.com/ebaymotors/Yamaha-Bans...1QQcmdZViewItem Quote
06BaNsHeE Posted February 10, 2007 Report Posted February 10, 2007 CPIs will work with an airbox.I ran it like that for 7-8 months.Get CPIs Quote
Snopczynski Posted February 10, 2007 Report Posted February 10, 2007 What kind of riding are you doing? Are the cubs gonna be ported? Quote
blaster668 Posted February 10, 2007 Author Report Posted February 10, 2007 What kind of riding are you doing? Are the cubs gonna be ported? Just a clean up port. I'm mainly gonna be using it for large oval racing. Basically two drag races with a corner on each end. Very fast wide open tracks, not the typical tt type tracks. I will also occasionally take it out for a trail ride. I know, I know....cubs cannot be used on trails. I just need something to scare the shit out of me occasionally lol. But seriously, there are lots of dirt roads, old railroad beds, and wide open fire roads that I'll tear up quite a bit on it. I need some splash protection, because even wet grass and small puddles will cause problems with pods. Quote
06BaNsHeE Posted February 10, 2007 Report Posted February 10, 2007 I would definately go with CPIs then.And no im not the biggest fan of cpis.Im a SHEARES guy Quote
theshee Posted February 10, 2007 Report Posted February 10, 2007 Yeah go with CPIs for sure. Shearers pull on top way to much for trails, but you would be alright with CPIs. They are still a high reving pipe, but hit better in the mid, and not so drastic on top as the shearers. You will be happy with CPIs. :thumbsup: Quote
blaster668 Posted February 10, 2007 Author Report Posted February 10, 2007 Cool, I really like the way CPIs look too. Can anyone show me a pic of their CPIs with the seat off from the top? Also, any opinions on whether rockets would work? I'm pretty sure T5's would but I don't know if they'd be much better than the FMF's. Quote
r/atvshee Posted February 10, 2007 Report Posted February 10, 2007 not the best, but its all i have for now hope that helps :thumbsup: Quote
theshee Posted February 10, 2007 Report Posted February 10, 2007 I will get you some under the seat pics of CPIs tomorrow. :thumbsup: Quote
06BaNsHeE Posted February 10, 2007 Report Posted February 10, 2007 not the best, but its all i have for now hope that helps :thumbsup: Hey are you still runing 33pwks with those smallbore CPIs you used to run?Im just curious to see how you like it.I will be racing my friends 7mm cub like mine,I have Inframe BB shearers and 38pwks and he has CPI smallbore inframes with 33pwks.Hes really confident and wants to race 1/4 mile for $$$$$$.My gearing is 16/39 Quote
r/atvshee Posted February 10, 2007 Report Posted February 10, 2007 those were actually pj34's. they were nice and the throttle was snappy. but i switched to pwk 35's due to the cub. Quote
