Nice set of bikes there
thanks man, hope to get back on it and find a solution for my leaking issue. Once that's sorted it'll be time for a new carb (going back to two possibly?) then some fresh paint.

Well work on the bike came to a stand still this winter after moving but starting to get back into it, almost have a solution to my oil leaking problem figured out. I'll post up the fix if it works, then if the works out its on to the carb and paint.

hey man, i came to check out your bike after you commented on my thread.  i love it!  the mono carb setup is a cool idea, i've never seen that done on a twin.  how's it working for you?  also, that new seat looks SO much better, it really gives the bike a nice look.  keep updating, i'm excited to see what happens, especially with paint!

Thanks man, the single carb is so much simpler, there is a kawi twin owners forum where I got the idea from and alot of guys run them. My carb is old and the slide likes to stick a little so I'll be replacing it probably with either a vm or tm mikuni before to long. got some work to finish on my car before I get back on the bike though.

i may have to give the single carb a try someday!  also, i was at my parent's today messing around in the garage and i took a look at those forks for you.  they look to be in good shape, but i forgot to take a camera, so i'll have to get pics of them later this weekend for you.

alrighty, snapped a bunch of pics for ya.  the only marks on the fork tubes were left by the yokes and are easily removable.  i was able to scratch through them with my thumbnail, so they are not permanent.  other than that, the only problems are a single crack in each of the dust covers, and there are caps for the tops of the tubes and one is missing.  lastly, i know i have the triples somewhere, i just wasn't able to find them tonight.  i didn't go crazy looking since i wasn't sure if you needed them or not, but if you do, i'm sure i can find them.  ok, on to the pics.  enjoy!

Awesome man, I don't know if you are in a hurry to unload them or not but I am definitively interested in them it just might be a few weeks before I can get them had some unexpected expenses pop up this month. And I would just need the forks my inter tubes are the problem with mine as they are pitted pretty badly above the fork seals, the work fine just look like crap.

And got a fix for my clutch rod shaft. Here is what we came up with.
brass bushing and valve seal

Had my buddy turn down the bushing to fit the case and the ID to fit the seal

Tapped the seal into the bushing then the bushing into the case. Turned out pretty good, waiting on my new clutch plates to get here to put the motor back in the bike


So now hopefully I have an easily replaceable seal the is relativity cheap

Thanks, I wasn't about to waste more money on a 30 year old seal again so me and my roommate came up with that. Seems to be holding up so far.

Just got a new vm32 from dime city, still working out the jetting. Rode down to the moto gp race in Indy over the weekend and it was running rich the whole time. I'm thinking my intake design is to blame for some of it, the inside diameter is a little larger than the carb holder so I think it may be dropping fuel in the intake as the air slows entering the manifold. Don't know for sure have to play around with it some more.

I've got a question about your 440 swap.  Just pistons/jugs/head and cover?  all the other parts are interchangeable?  also, you notice a big difference in overall power? low mid high range?  I have an old 440 motor I got for free from a friend wasn't sure what to do with it I have all the parts for it except valves and cam.  Would I be able to do the swap same as you?
