Snopczynski Posted September 21, 2009 Report Share Posted September 21, 2009 None of the low-mid pipes are going to do anything for you but narrow your power window. You cant just slap a low-mid pipe on with 34mm carbs, and a drag port and expect it to work. Closest your gonna probably get is those cpi pipes. You need to swap out the cylinders and get smaller carbs to make it a trail machine. Quote Link to comment Share on other sites More sharing options...
Sammy Posted September 21, 2009 Report Share Posted September 21, 2009 Sell the Carbs, Cylinders, Pipes and Reeds to fund your TRAIL bike. Then buy 28mm carb, aggressive trail port, pro circuits and a nice low tension reed setup. Quote Link to comment Share on other sites More sharing options...
John Posted September 21, 2009 Report Share Posted September 21, 2009 I agree with what has been said by both previous posters. I just wanna ask you this, what did you think was going to happen when you went and had a drag/dune port done to a bike that is gonna be in the woods? Along with adding those carbs to the mix as well. Quote Link to comment Share on other sites More sharing options...
RippinShee Posted September 22, 2009 Report Share Posted September 22, 2009 Just work the clutch a little more, and you'll be fine. I have that setup and if you stay in the powerband it runs fine. It's not a four stroke. It takes a little more work to ride, but it can be done. Quote Link to comment Share on other sites More sharing options...
bbcmudtruck Posted September 22, 2009 Report Share Posted September 22, 2009 If you pay for the shipping you can try my t5s. I ride in the woods/trails and have a 4mil dune port with 35s and t5s. I get along pretty good with that setup. Quote Link to comment Share on other sites More sharing options...
coronakidd Posted September 22, 2009 Report Share Posted September 22, 2009 i wood ride my 4mill cub cyl. with vforce3s billet intakes and 35 carbs i run trinity pipes and love the way it runs i ride tight virgina woods and even cut trails with it.My shee hits you in the back of the neck as soon as you grab the throttle and twist it open. I think your problem is the port job. I just have a clean-up port on mine and you said its not tuned quite right those two problems alone can give you lag or slugish feeling off the bottom and into the mid range of the power curve the way the cylinders are ported there could be nothing until you hit the top which is what you want in drag racing full wide open throttle power ( just ride it like you stole it balls to the wall bounce off the trees and keep going youll never notice the low end loss) Quote Link to comment Share on other sites More sharing options...
volcrano Posted September 22, 2009 Author Report Share Posted September 22, 2009 well i am an idiot thinking that if i went for all out hp in a drag port i would get through the woods easily.well im stupid cuz the power curve is poop.i had t5s,and they were better but i tuned it on the street and thought the cpis were better.i needed to tune it in the woods-the t5s were prob better for my app.well before i ship my cyls-id like to try another combo.i want to try pro circuits-and maybe throw my 26,s back on-just to try guys.should i take off my intake w built in crossover too?just wondering if that spacing helps or hurts low end.im going to try this because if im going to cahnge pipes and carbs-id like to salvage the season before i rip into jugs,but ill already have the other parts id need anyway.thanks for the help guys-but i absolutly hate using the clutch when its possible to rip without with the right combo.

coronakidd Posted September 22, 2009 Report Share Posted September 22, 2009 (edited) what gear you runin and tire size swap pipes out get your jetting right i used to run a 13 40 with 18 inch tires back in the day now im running a 14 40 with 20s i would leave the carbs and intake take a bunch of jets with you on a woods trip and jet while you ride nobody cares how long it will take to ret carbs or how many times you do stop to rejet if you have enough beer Edited September 22, 2009 by coronakidd Quote Link to comment Share on other sites More sharing options...
coronakidd Posted September 22, 2009 Report Share Posted September 22, 2009 got 2 thinkin if its tuned right dont matter where your at its right i tunned mine in the drive way never touched it since need to tune for riding style i dont tune my drag bike the same as i tune my woods bike two different ways of thinking on tuning styles but same still goes for the above post if you fell you need to tune in the woods while you ride then due what suites you best Quote Link to comment Share on other sites More sharing options...
bbcmudtruck Posted September 22, 2009 Report Share Posted September 22, 2009 I will trade you my t5s and some cash for you cpis. Did you try to bump the timing up? How much compression are you running? More compression as well as timing will help you on the bottom end. Quote Link to comment Share on other sites More sharing options...

How much compression are you running? More compression as well as timing will help you on the bottom end. timing at 0-when at +4 the bottom was better but top end blew-thats all it has now.called motor buy who ported it-its not a dune/drag but is aggresive trail/dune.hes hard to talk to-no real answers for tuning.he ported for t5s but said i could run cpis with no mod to his porting?i just want a snappy bike that rips and went the wrong way.compression is 155 psi per cyl-again timing at 0.it has 20cc domes.what pipe will be good for ported motors-in the woods thats not a t5.i already ran those-not too crazy bout them.gearing is 14/41 with a 20 inch holeshot-that actually looks 2 inches bigger than all my buddies 20,s-the old style holeshots.

papa_smurf49319 Posted September 22, 2009 Report Share Posted September 22, 2009 paul turners are good woods pipes, but pricey. Have a set but they need some work, theres some dents, and one is bent a little bit. Have fatboy silencers also. Quote Link to comment Share on other sites More sharing options...
