Yamaha XT 600 single carb + KTM shock - How it was made
 

Starting point: A Yamaha XT 600 3UW year 1993.
A picture says more than a 1000 words, so there will be more pictures than words in this thread (I’m terribly sorry about the quality of some of the pics. Apparently I chose to use an extremely crap camera).

Preparation:

Welding of re-enforcement (A good part of the metal that sits between the 2 vertical frametubes where they meet the ”spine” had to be removed to facilitate the carb. Furthermore I had to move the upper shock mount approx. 5 cm back to make room for the air inlet tube):

My homemade manifold. I initially bought a 2-1 manifold from a Grizzly, but it was way too long and the carb would be located too long back. Furthermore the manifold bending made the carb hit the startermotor.

I had to fabricate a new inner fender as i’d removed the airfilter/batterybox :

An airfilter is also needed:

Hehe yearh you're right. Although it actually worked on the preview. The pics are uploaded to docs.google.com and retrieving the links was a nightmare. I'll try to upload them somewhere else

Now the pics should be showing :D

what kinda air filter did u use for the carb dude?
now we are expecting to see a vid or something man :P

Just a k&n clone from a car. What I had lying in the workshop

First start-up with the Carb. Bike has now done 3000km since and has been tuned in:

Sounds amazing... can't wait to put mine on!! Your Carb is a mechanical moving Carb right?

Yepp. A Keihin fcr 39 flatslide with accelerator pump (which is not working on the vid. That's why it stalls when I give it fast full throttle. It,s now fixed)

If mine doesn't work properly u will hook me up with one too? :D:D:D

By the way do.u have detailed measurements? Did mine with a ruler so they're not accurate...

Actually I also just used a ruler and a Dial caliper. Use a piece of papir and draw up the intake mounts and holes on the paper. Then transfer the Drawing to a piece of metalplate approx. 5mm thick and build it up from there

http://youtu.be/3B8oBMBV7LY just converted mine... whole day yesterday I was trying to adjust the carb... I've got some un burnt gas and when I open the throttle really quick sometimes it lags... smaller fuel jet maybe? I've opened up the Carb and put the the omega safety on the top notch on the needle...

Bravo. Good job :). I see you Got the manifold mocked together. What carb are you using? Remember to only tune one thing at the time :). How much did you have to alter the frame? It sounds on the vid That you have some piston or valve rattle. Jakob
