Big Red carb acting weird...

[Thorpe]

Just had the carb off my BR. Pulled it down, cleaned the snot out of it and put a new choke valve and a rebuild kit into it... Put it back on the trike, gave it one kick and it idled about 200 rpms high... Pretty darn minor... Took it for a test ride, and in low gear, from idle to 1/4 throttle it has a little bog, and then it pulls like everything. Its not as noticable in second and third. Even get a occasional burp out of it in those low rpms, but runs great through the mid to top end. My question being, does it sound like it is a needle adjustment issue, crap in the low speed needle, or what about the synchronizing between the butteryfly and the slide....? Any suggestions are greatly appreciated...

You should have checked the sync between the butterfly & the drum, but you should be able to do that with it on the bike. Are you running an air filter? Is it clean & oiled properly? Air filters can goof things up.

Brand new air filter, and oiled... How is the sync supposed to be set up? I have it set so the slide and the butterflys are at the same time... I probably have a .005 gap at the adjuster. Is that not correct?

[smvorndran]

That should be good. I think the manual says no gap, but .005" probably isn't anything on drum/butterfly sync. ????????
