dirtydownunder Posted April 24, 2012 Report Share Posted April 24, 2012 thats ages away, you will change your mind so many times till then. you can get aftermarket cylinders from any of the BHQ sponsors. i think you can get stock bore cubs, but you may aswell go 421 cub. +4mm stroke +4mm bore. or if your bike is stock, just get your cylinders ported and play with what you got. numura's are bottom shelf, i wouldnt bother with them.

Jereme6655 Posted April 24, 2012 Report Share Posted April 24, 2012 the 392 athena kit isn't prefered by alot of guys that have tried it before. alot of the guys come back saying the same thing.....didnt make as much power as they were expecting.... however alot of those guys usually wound up contacting a sponsor and wound up either with a strong port job or a different aftermarket kit from our sponsors and love every minute of them.

RiDeTRIKES250R Posted April 24, 2012 Report Share Posted April 24, 2012 (edited) if your going to be doing alot of ice racing or high RPM riding, a 350 cub would be a hell of alot of fun. I have built several 392's for people and they love them, personally I love the 400pv series cheetahs, they make incrediable power out of the box, and with porting touching 100hp is not out of the question on gas.

ticktock Posted April 24, 2012 Report Share Posted April 24, 2012 Really for that kind of money a port job will liven up the stock cylinders a lot, then you add new pistons, cool head and you are at the same price with just as much to work with.

UPbansheeRacer Posted April 25, 2012 Author Report Share Posted April 25, 2012 i think i will just send my cylinders out and have them worked on and ill throw in a new wiseco top end while im at it i got a chariot head with 19cc domes so i got cool head covered just need some cylinder work done going to do it before ice racing next winter how much does porting cost and what would be a good BHQ sponsor to send them to?

UPbansheeRacer Posted April 25, 2012 Author Report Share Posted April 25, 2012 i do like the sound of a 350 cub tho my bike is a trail bike and an ice racing bike i dont need a 421 or anything but the thought of standard bore cubs intrigues me what sponsor would you suggest contacting?

fuller1986 Posted April 25, 2012 Report Share Posted April 25, 2012 call brandon at wildcard racing, he is amazing, retarded smart about banshee, any questions and he will have an answer for you i called him and bought a full top end nothing but a top notch experience, hes your guy and very reasonable. but i do believe he said it was going to be 280 to port, but either way a phone call is free so grow some balls and call him you wont be disappointed i wasnt. thats my 2 cents Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted April 25, 2012 Report Share Posted April 25, 2012 I have heard decent things about Brandon at wildcard. I went with Jeff at FAST and I had an awesome experience with him as my motor builder. Hell, he even helps with other stuff like problems with your bike. Great guy in my book..... I have also heard good things about Kevin at hjr Quote Link to comment Share on other sites More sharing options...
Larry's Shee Posted April 25, 2012 Report Share Posted April 25, 2012 Be sure to be in contact when you get closer to your build so you can get it together and tuned by racing season, almost always takes longer than you think. Quote Link to comment Share on other sites More sharing options...
