86 vfr 700 extremely hard to start under 70 deg.

um have you taken the fuel lines off?
sounds like you have the vacum line and the fuel line swappede?

 

750 vs 700

You will never notice the difference between 700 and 750.:thumbsup:

 

I have not had the fuel line off but that does not mean that someone else did not mess with them. But would the bike run fine once its at operating temp if the lines were swapped? I'm telling you this bike runs flawlessly after the initial start up.

 

if you take your carbs apart, pull your pilot jets out and clean them as well, that and richen your idle mixture a little bit, my 84 750 was doing the same thing and once i enrichened the mixture a little the problem went away

 

Carbs

Have you cleaned them yet? Just askin. If you would like I would gladly go through them for you.If you do them yourself it is not that hard and would be glad to help in any way. I don't charge to work on VFR's......

 

Muuther bluuuudy Theresa, ain' it guvna' ??

Make sure he washes his hands aNd cleans his nails and uses hand sanitizer b4 he touches your bike.......,,,,flu, don'tcha know !

PRE-sanitize and
disinfect !!!

 

Just read this thread (unless you have it handled already) and the first thing that popped into my head is float level. It's not exactly intuitive on these since the carbs sit at an angle and I frequently find it off spec. If it were a little high, it could tend to 'splash' fuel into the combustion chamber...especially on the kickstand. Try leaving it on the centerstand, and see if it helps.

 

Thanks for the offer Toe but I think I'm a few thousand miles away from you, but that would make a nice road trip lol.:biggrin: I have not had a chance to pull the carbs off yet but will soon I was reading the manual I had yesterday and it had a different startup procedure than I'm use to it says between 50 and 80 deg. to start with full choke no throttle run for 30 sec. then gradually decrease choke. I'm going to give this a shot and she what it does I will keep you all updated. :thumbsup:

 

Ups

I have another one....ok two more to do in the next month so if you mailed the carbs to me I could test them on a known runner and make sure the are dialed in and send them back....could turn them around in a day or two.

 

My bike needs an oil change in about 3,000 miles. If I leave now, that should get me there in about 3,484 scenic miles. :crazy:

Hmmm....

Sorry for the hi-jack Eddie. Good luck getting her up and running perfectly.
