Hi

hello i just purchased a 1988 vulcan 750 about a month ago and i figured i would join this forum for some good advice. i love the bike! its comfortable and has some good looks!

i got the bike with only 8400 miles on it. it had sat for 3 years though without running so it needed some work to get goin'.

fortunately, 3 years ago before the owner put it up he had $1600 in maintenance done on it. new forks seals, oil, coolant, carb rebuild, ngk plugs and wires, etc. and it just so happens the guy that worked on it 3 years ago helps me with my 72' honda.

i have got the bike running after a thorough carb cleaning and an oil change and new plugs. (btw those carbs were very difficult to put back on lol) it runs but still not perfect. on occasion it wants to die when i give it gas after it has warmed up and a little bit of white smoke comes from the exhaust on the front cylinder. i am guessing the carbs need to be synced together? the adjustments were not tampered with and im not sure if they will need to be re done or not. i read the forum thread about syncing them and i got some good info but i was just wondering if there is anything else i should look at?

any help will be appreciated! id like to get this bike on the road asap! thanks

Welcome to the forum and all it's benefits! I'm sure others will chime in on your questions, or you can repost them in the specific areas of the forum that apply.

I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!

Check out Knifemaker`s post #4 on this thread: https://www.vn750.com/forum/showthrea...ight=carb+sync

It appears that a two cylinder engine with constant velocity carbs, like the VN750, seldom requires a carb sync. Before doing a syncronization, check that both carb throttle linkages are starting to move at exactly the same time. If that doesn`t correct the problem, you can then constuct one of the inexpensive sycronization manometers mentioned in the various threads on the subject.

Usually white smoke is a indication of a possible bad oil ring. You can try a compression test on the front cylinder. See if the rings are worn.
