Justintoxicated Posted February 22, 2006 Report Share Posted February 22, 2006 I have heard various answers as to which perform better with a 4 mil cub. I'm looking to get some new pipes for my 12-port (non stroker) but will be switching to cubs next rebuild. I'd like to see some dynos (preferably from the same place) that show one pipe vs the other. Shearers vs CPI's welcome also, but I'm thinking I want a little mroe lowend and smoother power to make it easy to hold wheelies up the big hills etc. I'm not into drag racing much. Thanks!

Thanks! 477415[/snapback] I have a dyno run posted of mine here with my old 12port, with shearers they seemed to make good power all around to me, the powerband hit really hard also. bigboybanshee rode my bike, pm him and ask his opinion. http://www.planetsand.com/ubbthreads/showf...true#Post250539 Quote Link to comment Share on other sites More sharing options...
Justintoxicated Posted February 23, 2006 Author Report Share Posted February 23, 2006 (edited) I rode my friends bike with the same porting and shearers and I did not like it, no low end and one hell of a hit on top, not going to be easy to hold wheelies up olds pattons china etc with them.. I want something that will work better than my Fattys with my porting but be more optimal for when I get cubs this summer. I know the shearers make more power, but I'm looking for a broader power band with a little more low end. I'm not making a drag bike, but definately not a trail bike either! for some reason non of the Dyno's are showing up on those links.

wesw Posted February 23, 2006 Report Share Posted February 23, 2006 you can ask bansheefreak he has rode my bike. it had low end. sure it wasnt like a 4 stroke but very broad powerband. and many others have also puddle jumper took me riding in trails in the woods that i would only take a 400ex to. it did fine. ask jim, he'll give you the best advice on what to get.

Justintoxicated Posted February 24, 2006 Author Report Share Posted February 24, 2006 so in that graph the red and bleu is what on what setup? heh you have a 4 mil right? my neck hurts from laying on my desk sideways I like the fit of the shearers better, but I would have to get them chromed someplace else cause their finish sucks and mounting hardware isnt great either...You would think by now I would give up on the chrome thing, since every time I end up without my parts for about 3 months.... I thoguht the CPI's gave more lowend. It's is diffucult and chalenging to wheelie a banshee up a hill like olds. While this may be easy on a 4 stroke you hit the gas wrong on a shee and you will wake up under your bike. I don't need lowend like a 4 stroke I need some nice smooth mid-top since that is where you wheelie a banshee, lowened just helps get back on the pipe easier (which is important when you mess up and have to drop the front end) but when I tried the shearers they power hit very hard, this will lift the front end up right away, but as soon as you ease off the gas a bit the front end will go back down, if you hit the gas again before the front is down all the way it will pull too hard and I could go under the bars. in fact I'm a bit skeptical of even putting cubs on my banshee, as this is already going to make it much mroe difficult than the nice smooth power on my 12-port. Ge anyone understand what I am trying to say? I'm looking more for a broad power curve than peak HP, the broadest power curve is what I want, it should be fast enough with cubs no matter which pipes I choose. I'm even thinking about sticking with my 33mil carbs... Quote Link to comment Share on other sites More sharing options...
Big Blue Posted February 24, 2006 Report Share Posted February 24, 2006 so in that graph the red and bleu is what on what setup? heh you have a 4 mil right? my neck hurts from laying on my desk sideways The red is before jetting and blue is the final result, this was a 12 port 350, +4 timing, 18cc dome, and 30mm pwks with pods. I dont know why it loaded the image sideways when I put it on planetsand. I didnt have any problem with the hills at little sahara OK, but these are tiny dunes compared to what you are riding on, I would almost say that you will for sure have to stay away from shearers, CPI's would be a little more like what you are wanting I didnt like the way they felt power wise on my bike, and I always burned my damn legs on them.

Justintoxicated Posted February 24, 2006 Author Report Share Posted February 24, 2006 I would have to say that your low end has alot to do with your porting, more so than just different pipes. I sold my 7MM cubs for this reason and went back to stock cylinders. 478492[/snapback] Yea, for sure, riding Inflames Banshee with same porting but different pipes there was a huge difference. THe power was all up top. Sure my 19C domes are contributuing and possibly V-force reeds, but still I think it was mostly the pipes... Damn CPI's are leg burners? Now I dunno if a 4 mil will be better with CPI BB or SB. I'm sure my current porting is better with SB, but im thinking into next season what will be better.
