New Guy, New Project

A wheel swap to a 17" wheel would in fact be a much better setup. They manufacture purposed dirt track tires in 17" and 19" sizes. While this 16" tire I'm running works great, it'd be simpler to run the 17" dirt tire. Of course a 17" with a wider availability of sprocket choices would be a perfect world, I'm not holding my breath.

EDIT: I'm also checking other manufacturers parts at random just in case they have one that'd fit.
 
Hey everyone, I just bought me a 82 XS400 a couple of weeks ago. No title, no front wheel, no handlebars, no controls, no seat, no fenders, no front brakes. . . Perfect for a flat track race bike. Been pulling off relays, flashers, kickstand kill switches, and other fluff. I have spark, she's fired for me with carbs off and a puff of starter fluid shot into the boots, the wiring harness has been cut down to the bare minimum. Just now getting ready to start cutting extra weight off of the frame and getting my controls set up. I have a line on some renthal handlebars to use. I need a throttle and to rig a bracket on the carbs because someone decided to remove the stock one. Gotta bend the rear brake lever to clear because that was missing as well, using a take off from some other jap bike I had lying around. I'll throw up a bunch of pictures in the next day or two.

Hey I am building a Road race bike out of a 1082 xs400 are you going to do any engine mods I am green to the xs400 I used to race big bores where do I begin I thought about fresh rings and milling the head or deck height 50 thousandths. What do you thing are you really friendly with the xs400 internals

Ant:thumbsup:

Hey Ant, I'm not doing any motor work just tuning the carbs and building exhaust. If you really want to disembowel your motor and hop it up, check out this thread. These guys are going pretty in-depth with modifications.
 
Ok, here's the full update on what I've done since the last round of pictures.


So Eventually the bike was ready.


It ran and everything (Video, clicky)


Held up to field testing which I'm sure the neighbors adored (Video, clicky)


Of course the first time at the track we were pretty slow (Video, clicky)

while trying to go faster I lowside and break the shift shaft in the middle of the case.


Went to the track a couple more times



Like any good project it needed some tweaking



Finally it looked like a real flat tracker
 
The big problem being, I'm never happy. I just chopped the exhaust apart, I have to change the way the #1 pipe is routed. As it is in that last picture, the tire rubs against it when the suspension is compressed. I'm thinking about routing along and having that side cross over under the engine and then join and then both swoop back up into a high pipe.
