375hp banshees Posted March 27, 2007 Report Share Posted March 27, 2007 Do you have an air box, with or without the lid? what kind of air filter setup are you running?? Dave will cpi's have any benefit on A stock motor (or 1 w/ his mod's) than say fmf's ect. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted March 27, 2007 Report Share Posted March 27, 2007 Dave will cpi's have any benefit on A stock motor (or 1 w/ his mod's) than say fmf's ect. In my opinion....NO. A Shearer, CPI....or other mid to top or top end pipe is a waste of money on a stock port/stock stroke banshee. FMF or T5...even Trinity Stage IVs are a better choice. Hell, if he never plans on getting it ported (yeah, like that ever happens) even a T6 pipe. Especially with stock carbs to boot. To get the most benefit, dune porting, CPIs and some 33 carbs/intakes would be a very nice boost and complimented package.... Just my opinion....

dajogejr Posted March 27, 2007 Report Share Posted March 27, 2007 that's what I thought sorry to hyjack :biggrin: You've actually done this poster a favor. I've read a few posts where guys bought drag style pipes for a stock port OEM motor and were happier with their old setup, FMF...whatever. Now....if you're getting the pipes now with plan for the future...understanding it won't run to it's potential, go for it. (Or...if you happen to get a STEAL on some good pipes for a future build...LOL ) Again, your mileage may vary....and this is only my opinion.... :biggrin: Quote Link to comment Share on other sites More sharing options...

dajogejr Posted March 27, 2007 Report Share Posted March 27, 2007 Reeds generally improve midrange response... 200 for CPIs? Yeah, you did very well...nice steal. Normally....you may have to lean out your needle one clip position for VForce reeds...but, if it's running fine in the middle...don't mess with it. Is it blubbery at the top, or is it revving fast just not going anywhere. I'd bet you have to up the main jet 1 to 3 sizes...CPIs flow a lot more than FMFs. However, do the plug chop to be sure. If you do the chop right....and it still has no top end pull...well...time to get porting to fit better with those pipes. http://www.dfn.com/benkaren/plugchop.html Quote Link to comment Share on other sites More sharing options...

Reeds won't help top end pull. I'm estimating 1-3 larger mains only on my belief that CPIs flow alot more. Do you have stock gearing? Stock tires? 6th on a banshee is steep....are you running on pavement, hardpack dirt or sand? If sand...you probably simply don't have enough motor to pull the top of 6th gear. When my 96 was stock motor, I had pod filters, T5 pipes and advanced timing. it was spot on jetted. But...when we went for a trail ride in the UP, some of them were pretty sandy trails. My motor wouldn't pull 6th..it would just kinda hang about half throttle....no more. Hard Pack or pavement there isn't as much resistance....it'll wind 6th gear out just fine, normally...if in tune. Since you can wind out 6th gear (lucky you...) do the plug chop as described in the link I provided. If the plugs look good....you can either shorten your gearing (smaller up front or larger in back)..but, you'll be shifting more...or do some more mods. Again, reeds will give you more midrange, timing more bottom and mid. Both are great mods....but to be honest, I'd wait to buy vforce reeds until you get a ported motor...they benefit more.

FMF or T5...even Trinity Stage IVs are a better choice. Hell, if he never plans on getting it ported (yeah, like that ever happens) even a T6 pipe. Especially with stock carbs to boot. I am going to partially disagree with you. I think CPI's with stock porting might be tough to justify. If you have a port job, with stock carbs, on a stock stroke engine, I think CPI's perform fairly well. It all depends on where you are riding though I suppose. There porbably are better pipes out there for the this particular application, but if it's what he has, then it's what he has and we should try and help him. Stock carbs get a bad reputation because of the TORS crap and the slide to barrel tolerances. Beyond that, the stock carbs will allow more air through than several other brands/styles of larger bore carbs. (I know some one is going to get all butt hurt if I immediately mention which larger bore carbs) :ermm: Quote Link to comment Share on other sites More sharing options...

Needle and air screw adjustments will be something you have to fiddle with on your own.................................I see Plug Chops in you future.

dajogejr Posted March 27, 2007 Report Share Posted March 27, 2007 Oh yea....there is no doubt pipes hold up a banshee more than the stock carbs do... With stock porting, I don't think CPIs are a great choice. But...for 200...shit, I couldn't pass that up. I myself want Shearer inframe big bore pipes for my drag bike, but I'm getting a set of big bore CPI out of frames with silencers for 300. So..until I can get what I want, I'll get what I need for now... After all the jetting and working on stock carbs I've done, Mark....I honestly think PWK series are leaps and bound better and easier to work on. As said, they get a bad name from the TORS and idle and stuff...but, I like the simplified design of PWKs... Stock carbs can and have been made to work very well....there's no doubt!!! Just saw your post...Mark. 32.5 pilots I can guarentee will be too fat. I know riders that used 32.5 on alky.... 27.5 or MAYBE 30's...but 32.5 are way too much...even if he had a drag ported motor.... Plus...he said it runs great all the way till 6th is pinned....

For $200, even if you had to rechrome the pipes, it would still be a good deal. Why the hell don't I find good deals like that? :: I am pretty much up my own ass trying to figure out what I am going to do for pipes for my triple. :shoothead: PWK or PWK Air Stryker carbs are good carbs and they are much better than stock. My previous carb comments was reffering to some other Keihin and Mikuni carbs. :beer: Quote Link to comment Share on other sites More sharing options...
