To make sure they were clean I had to unscrew them and take them out. Thanks for any help you can provide.ĭid you clean out the small pilot jets (idle circuit) I had to poke a small wire brush bristle through mine to get them unplugged. Could these be causing my problem?Īny other ideas? I am by no means a mechanic, so I could be missing something obvious. I haven't the slightest idea of why these are there in the first place. I couldn't find replacements for these, so I left them as-is. They were mostly hard, and probably not providing good seals. The only thing that I skimped on were the two rubber plugs at the bottom of each jet block. Even if I missed a couple of the passageways I would expect it to run better than this. I know about the seafoam fix, but I would assume that since I thoroughly cleaned the carbs, I shouldn't need to use the stuff. Any hint of throttle and this thing dies immediately. I have tried backing off the choke while very gradually increasing the idle via the idle adjuster, no luck. I read that these bikes don't like to run without the airbox, so I installed that and encounter the same problem.

It will run just fine with the choke on full up to 2500RPM or so. I was relieved when the bike started, but after warming up, repeated attempts to take out the choke fail. After re-assembly, I balanced them by sight on the workbench and got them back on the bike. I completely dismantled them, soaked them in carb cleaning solution, blew out all the passageways, and replaced all gaskets, o-rings and damaged diaphrams. I decided to give the carburetors an overhaul. It was no surprise that it would not run for me when I got it home. That's of course when he stopped riding it.
He says that it was running kind of poor, so he did some 'fiddling around' with the carburetors, and then it wouldn't run at all. It has since been sitting in his garage unused. I bought this bike from a co-worker that had ridden it up until about 10 months ago. Hello everyone, I am the proud new owner of a 1983 Yamaha Venture Royale.
