1996 vfr

Hi i have a 1996 VFR750, and am looking for some tips and parts. I bought the bike last year it had been sitting in a barn for several years with just under 7000 miles on it.
I got it running, put new rubber on it and changed all the fluids, filters & plugs.
Last season i tried to drive the varnish out of the jets using several different fuel system cleaners. Seafoam worked a little, I did put just over 2000 miles on it last year with cleaner in every tank of premium fuel.
So i don't know what forum to go to and ask about jet cleaning. The bike runs fine at idle, though it does not seem that the choke is very effective, through just under 4k (it is weak right on the edge of gasping for fuel in the lower revs) then it goes flat until it finds 7k and then pulls like a mule until redline. So i am missing the meat of the powerband. Can i pull the carbs and use spray carb cleaner in the jets and be effective? Or will i need to pull the jets and clean them along with flushing the carb bodys?
Any tips or ideas would be appreciated. I am hoping to do this without separating the carbs. Make some choke & throttle cable adjustments and resync carbs.


Also i would like to find a new aftermarket windscreen for it. The original is scratched , cloudy and looks like hell. Any tips on where i can find one, opinions on double bubble & touring screens would be appreciated.

Thanks for any and all help, Kirk

 

You need to remove idle jets, main jets together with their tubes and clean ALL holes with a bit of wire + carb spray + compressed air.

The long brass tube that draws fuel into the choke circuit needs periodic roddong-out with wire too.

As with anything that's been sitting so long, you need an inspection for fuel tank rust, and you should thoroughly flush the tank of particulate matter, water, or left-over varnish and consider a new fuel filter.

Might be helpful to remove air filter and watch vaccum pistons moving up and down in response to throttle while engine is running cuz they get sticky sometimes and may cause a problem like yours.

A check of the air filter is another necessity as small rodents ofter build nests there or use the airbox as a nut stash.

 

See? There you go. Answers. And don't fucking doubt the Squirrelman! He's a guru too, you know. lol

 

Thanks boys that has been great help

 

Does the bike have an after market exhaust, a jet kit or is it bone stock? Be very careful if you do use wire to clean out a jet. I would only recommend very thin copper wire strands if at all. Carb cleaner and compressed air is your best bet (many a jet have been ruined with wire that is too hard or sharpe). If it's weak up to 4k the pilot jets may need attention and or mixture screws may need adjusting. 2 -2 1/2 turns out should be in the ball park. Run the bike up to 4k with the choke partially open and see if it runs a little better or worse. that'll tell you if it's starving for fuel down low. Over 6-7k the main jets take over and it sounds like your good there. AND NEVER EVER SEPERATE the CARBS from the Plenum!!!!!!!!
