    Well after nearly 2 1/2 years I finally put the final touches on my VFR750. I have waiting since 1990 to own one of these pups and today is the day she is ready for the road

    Being in Canada there were not that many sold and fewer survived in good shape. I purchased mine 2.5 years ago and being from a province that does not have a safety inspection program I

    went through the whole bike to check and upgrade any issues

    Forks rebuilt

    Front brakes redone with new pads, fluid etc

    New tapered steering head bearings

    Rear brakes redone with new pads, fluid etc

    Clutch flushed with new fluid

    New plugs

    Engine coolant replaced

    New thermostat with new rubber hoses

    Upgraded the regulator with a Roadstercycle FH020AA Regulator, bypassed the old regulator plugs and wired into stator as close as possible, ( now 14.4 volts at battery ) and the new regulator has no heat

    where as the old regulator you could hardly touch

    Rebuilt the fried starter relay wiring

    The carbs were completely stripped with new gaskets, o rings, fuel lines etc etc,

    Shimmed the carbs for a little richer mix

    The bike had an aftermarket seat cowl and I was lucky enough to find a as new one sitting on a shelf

    As you may have noticed the side stand cover is missing but I am in the process of repairing the screw mounts and she will be 100%

    IMG_0474.JPG Man, there are times I wish I lived in the U.S. I think I could use some ones expertise like squirrelman#1 in carb building or buy another set, between the Canadian exchange rate of 35% and the high shipping costs to another county it is hard to purchase state side.

    I just got my 1990 VFR750 on the road after 2.5 years and just had the carbs cleaned and synced. I know it has been a long time since I rode a bike but the carbs have to be off. The other day I started it up cold with out any choke , it fired right up and it idled for as long as I wanted, but at times if I tried to bring her off idle it felt and sounded like she was stumbling, after the revs passed 2 grand she would rev to the heavens.
    Once she was really warmed up If I held her at say 5 grand than let go of the throttle ( or rotated it closed ) she would drop her revs until roughly 3 grand and then she would hang there for a few seconds before she settled down to a idle. In the past week I have driven it roughly 60 miles and the fuel consumption seems high. At this point I guess I will have to pull the carbs and see if there is something out of place or not hooked up right from the carb rebuild and if everything is ok there start going through the carbs.
    I should noted that the bike has a full Yosh exhaust with a K&N air filter, the jets in the carbs are marked as stock sizes, there is a thin washer under the main jet needle ( I guess to help with the installed pipe). I wonder if the main jets are truly stock, I have heard of guys drilling out the stock jets, if this is something I should check what is the best way?

    The needles have stock washers from factory. I wouldn't drill any of the slides of any of my personal bikes. Consider getting the factory manual for this model. I bought parts for mine from people in Canada as well as the UK. Its a World bike. Peace
