bada450r Posted May 9, 2007 Report Share Posted May 9, 2007 ok fellas,i m looking for out of frame pipes,the problem is i cant make my mind up.i got on 1 hand jhon from sandtoyz trying to sell me a pair of small bore shearers outof frame with the triple crome both on the left side for 500,these pipes are used,and in very good shape,and as some of you know shearers on one side have to be costum made,therefor costing[$$700] a little more than cpis.on the other hand i got lynn from lc performance saying that cpis make more horse power,and thats all lynn runs on his bikes,and i can get a brand new pair of cpis for 550,small bore.what do you guys think?ill be running this on a 421 cub on alky.i want some personal experience.thanks.i know this is been talked about,but i dont remember ever talking about out of frames. :: :shoothead: :shrug: Quote Link to comment Share on other sites More sharing options...

I think I'll be grabbing a pair of CPI BB OOF's though. Also how does your cub do on Alky. I thinking of switching to alky soon. :cool: Quote Link to comment Share on other sites More sharing options...

I thinking of switching to alky soon. :cool: alky gave me about 11/2 to 2 bikes,atleast thats what i was beating a friend of mine on a cub on gas,but his like 80 pounds lighter than me,and before we would change wins.ofcourse he is now going to alky as well so we will see.also how much are you paying for the bb?and where are you getting them?

r/atvshee Posted May 9, 2007 Report Share Posted May 9, 2007 I'm hoping to find a set at R/atv. We are trading the t-5's straight across for the CPI's. I'm very curious about switching to alky and see what my motor can do, but i dont like how quickly it gets used. Quote Link to comment Share on other sites More sharing options...
dynodon Posted May 9, 2007 Report Share Posted May 9, 2007 Jon from sandtoz has never steered me wrong. I have shearer pipes on my 421 cub, and I also had cpi`s at one time. I prefer the shearers anyday. I wanted both out the left, but matt would make anymore out the same side. I would snatch them up if I didnt already get new shearers. As for the alky, I wouldnt go back, atleast not for draging. Once you get it tuned in, you will agree. Quote Link to comment Share on other sites More sharing options...

shanYE west Posted May 9, 2007 Report Share Posted May 9, 2007 (edited) I know different builders motors favor different pipes. I would run what the builders suggests because that probably what he used to test and tune the motor with. My builder suggested shearer because thats what he used while doing R&D on the dyno.

I have Shearer inframes on my cub, and love them... i know it's not out of frames, but I'm sure the Shearers hit the same way. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted May 9, 2007 Report Share Posted May 9, 2007 Yep...Sefarian is a helluva guy....I got my Marvins from him. I'm a fanatic about Shearer...however, always a good idea to run what your builder suggests, it's their name and porting on the line.

No Limit Powersports Posted May 9, 2007 Report Share Posted May 9, 2007 We have run cpi's and shearers on the 4 mill cubs and the shearers pull harder everytime. Quote Link to comment Share on other sites More sharing options...
06BaNsHeE Posted May 9, 2007 Report Share Posted May 9, 2007 My builder says the same shit.Shearers over CPI anyday.I also noticed that the shearers pull harder on top than my old cpis. Quote Link to comment Share on other sites More sharing options...

But im down for a cub against cub match. Even though im still unsure about switching to alky. Quote Link to comment Share on other sites More sharing options...
Malott 1 Posted May 10, 2007 Report Share Posted May 10, 2007 I have ran cpi and now have shear out of frames. CPI's will pull a little harder out of the hole. But there has been alot of dyno's posted showing the curve of both pipes and practically all of them show the shear pipes keeps making power in the top end after cpi's fall off. Both pipes are good pipes and I have seen certain bikes that the cpi's turned better times than the shear. I have a couple of friends that have recently purchased huge motors from K&T and the pipes they send with them are CPI's. If you go with the shear same side and your going to be out in the dunes be prepared for the pipe mounts to break that's a given. And it sucks after you fork out all that money for a nice chrome finish and someone has to go in and weld a plate for a new mount. Their mounts are brased on and they will not hold up to alot of movement. I know from experience. I love my out of frames but my bike is strictly a drag bike on the track. I am one who feels the louder the better. But if you plan on spending the majority of the time in the dunes an inframe pipe will give you alot less headaches. I know a guy who had a 4 mill stock cylinder bike that tried both inframe and out of frame pipes on a 300ft track and there was only a couple hundreths difference in his times.
