87 VFR700 Problems

I just bought an 87 Interceptor, all body panels were apart, and the bike has been sitting for 10 months. Picked it up for $300.

I changed the plugs, new oil filter and oil, fresh coolant, new battery. I can sometimes get the bike to fire up, but it can't hold an idle for more than 10 or so seconds usually, and with the choke on the idle doesn't always goes up, sometimes up and down.

It's hard to start. When I did get it running, I couldn't get it to rev up very much, I had to give it just the slightest throttle blip and it would sometimes go up to 5k or so. When I had it WOT, it would bog down.

Suggestions? Fuel or spark problem? It has fresh 87 gas in it, the top box on the intake is missing along with the air filter.

Any and all help would be appreciated, I can't wait to get it running and together!!

 

Great price. My '87 had hose rot in the California pollution equipment that caused vacuum leaks and poor running, so I am in the process of taking that off.

I'd bet carbs need attention, probably full of varnish.

Don't run it for long without an air cleaner... of course you don't want to invest a lot of money until you know it is basically good.

 

Carb cleaning is next on the list.....

VFR won't run right without air filter.

 

Will a fuel pump from a VFR1000 work?

 

Getting it cleaned tomorrow (the carbs)

Anyone know where I can source a gas cap? I can't find any on ebay, mine is junk and looks like this:

 

Mine had a scratch, so I polished it, came out near mirror finish, pics don't show well.

 

That looks good.

However that's not my problems, I need a new one, the piece underneath it is busted and the lock part is too. I mean, will it seal like it is now?

 

Post a need a gas cap thread, if that don't work .....I emailed everyone on ebay that had a VFR700/750 part for sale, I needed a centerstand....most people said (good luck) but 5 hours later one was on the way.

 

Will do, thanks!
