Default Mikuni install problems

Was wandering if anybody knows how to attach screaming eagle air cleaner to Mikuni carb. The adaptor lines up ok but the mounting plate(which also is the breather bolts) isnt in the right spot. Do I have to have the breather to run, or can those be sealed off? If I could eliminate breather tubes, I could use washers and just have mounts shimmed to the right location. I'm kind of stuck on install until I figure it out. Thanks

The breathers are for the motor.. You can't seal them up.. I'd message DK Custom Products and see if they have an adaptable breather arrangement for your setup.

Yeah^, the engine still has to breathe. There are various banjos with hose barbs that can be used to replace the factory horseshoe and bypass the air cleaner. DK, Kury, and others sell them.

Make sure the intake donut seal doesn't roll into the throttle bore when you push it on. Open the slider to look in there and verify.

Don't forget to cut off the cylinder fins that hit the fuel bowl. They can keep the carb out of alignment and crack the mounting bracket...or worse...

Default Mikuni breather fit

Thanks for the help guys. Just as a follow up, I was able to flip the breather tube backwards and it fit on after that. Just had to run a new rubber hose back to the other side to reach the air cleaner back plate. Thanks again for the help.

Sounds like you have it sorted out, but here's the only picture I could find showing my backing plate, breathers, and Mikuni somewhat visibly... A short hose attached to a small K&N filter hangs off the downward-facing fitting on the left side of the breather hoop.

Hey man I just bought a night train that has this exact back plate and mikuni carb. The guy broke the back plate and I cannot find one to replace it, do you happen to know where to get this or a part number or something because I cannot find anything other than this thread so far lol.

I'll try to make a note to look. For some reason I'm thinking I have one.

Isn't there a part# on the back of that plate?
