dtmf Posted May 27, 2009 Author Share Posted May 27, 2009 dtmf, looks like your handy with bikes. keep up the good work and let us know how you are getting on drewps thank's drewpy . it's been 10 year's since i've had my hand's on a bike. this one was a real mess . it had alot of problem's . ran like crap the idle screw was missing it was just using the throtle cable adjuster to get idle . had a bad exhaust leak i was afraid that side was toast . but as luck would have it it's ok . the light's and key switch were a mess of cut up wire's stuffed behind the headlight . i had to redo all of it lot's of solder and heatshrink tubing . master cylinder had no screw's it was "glue'd "on and leaking badly . the whole front aftermarket faring and headlamp where held up with coathanger wire . i could not belive someone owned this raty snotty mess of a bike . all of this and more have been fixed the right way . i've bin lucky so far . the carb's still need some work pod fiter's are a must i hate that air box btw anyone know where i can get the valve shim's and the tappet locking tool . a good vavle adjustment will realy help me get this 400 in tune dtmf Link to comment Share on other sites More sharing options...

flutterball Posted June 8, 2009 Share Posted June 8, 2009 DTMF, Have the exact same bike, but my exhuast is in rough shape, was originally just going to paint them with black BBQ paint, but like the cut down look, so how did you cut down your mufflers? Did you have to make new ends, baffles? How much louder is the bike? would it pass inspection based on the noise level? Sorry lots of questions, but could end up following this root as well. THanks in advance Link to comment Share on other sites More sharing options...

THanks in advance i cut the pipes @ the weld just after the foot peg's . you could cut them about 3" longer before you hit the baffles .i did this mostly becuse the baffles where cloged up bad and cuz i like loud bikes . i'm going to get the mac 2 in to 1 pipe set and fab my own "muffler" in a few week's . as for noise it's realy loud and would never pass a noise polution test .i would do the inspection then cut them .it may not be wise to run like this for a long time with the decreased backpressure im not shure . post up some pic's of your's i would love to see it Link to comment Share on other sites More sharing options...
Moderator YamaHead Posted June 9, 2009 Moderator Share Posted June 9, 2009 i'm going to get the mac 2 in to 1 pipe set and fab my own "muffler" in a few week's . That Mac set-up isn't too bad for the $$...... Vance & Hines also makes a sweet 2 into 1 for this bike. Link to comment Share on other sites More sharing options...

dtmf Posted June 14, 2009 Author Share Posted June 14, 2009 i did a front shock oil change today . there was only about 1/2 a cup or less in them and it was black an nasty .very easy to do as long as you got a buddy to compress the top cap while you get that sob c-clip out . i went with 7wt feel's alot better. i can now "feel" the road . i'm still waiting for my EBC brake rotor and pad's to show up along with all new cable's and ss brake line's . the carb's are still a bit snotty Link to comment Share on other sites More sharing options...

flutterball Posted June 23, 2009 Share Posted June 23, 2009 Looks like your moving along on the re-build, know the idea is to get the bike on the road at a low cost, but would suggest you pick up a side panel for the bike, will make a world of difference in looks (does on mine), and ones available for a good price on ebay right now: item #260431337597 .

dtmf Posted July 19, 2009 Author Share Posted July 19, 2009 so i got some time to work on the pipes this weekend .i was going to get the mac 2 in to 1 but i just went ahead and cut up the old one's and welded some new pipe on then wraped them up . i cut out both xover's so now they are just straight pipes . the old pipes were double wall so i had to weld a bead around the inside where i cut them so they would not rattle around . they sound sooo loud i may baffle them . my new jet's and pod's from mikes xs will be here on monday then the tuning fun begin's . here's some pic's and a video enjoy Link to comment Share on other sites More sharing options...

dtmf Posted July 26, 2009 Author Share Posted July 26, 2009 i got the jet's changed out today also put on some pod's . cuting out the air box was a big pain . i made a new box for the battery out of sheet metal . since ive done the pipes and even after the jet change i still have some bogging in the low rpm's . in 1st gear @ a stop when i take off it feel's like it lag's a bit then pick's up halfway thru 1st and then it's fine i went one size up from stock on the main's 117-120 RH / 127.5-130 LH the pilot jet's where already up alot past stock . they where like that when i got the bike. stock is 35 and thet both had 42.5. my mixture screw's are out about 3 1/4 turn's and they are new got them when i rebuilt the carb's afew month's ago . here's a vid of her with with the new change's enjoy here's some pic's too Link to comment Share on other sites More sharing options...
