    After the excitement the '86 VFR750 brought me - memories, etc., it was hard to stop... An opportunity presented itself to pick up an '87 VFR700 in the very cool dark blue color - from a gentleman who is local and who posts on this forum quite frequently.

    This one is a bit more challenging than the last one - not running, with recently overhauled carburetors and a rusted out fuel tank. Some updates:
    • Ran electrolysis on the fuel tank for 2.5 days (sodium carbonate/hot water) followed by a pressure wash
    • Changed coolant
    • Reinstalled carburetors, air box, new air filter (needed a new bike for the extra air filter)
    • New battery

    Next up:
    • Overhaul the clutch master cylinder
    • POR-15 for the tank (already getting flash rust)

    On the horizon:
    • New fuel tank cap (Ebay special didn't cut it; need to go OEM)
    • Minor repair to right, front cowling
    • Tire replacement
    • New chain and sprockets
    Took out lots of crud from the tank. The bike looks nice in full regalia. The satisfaction of bringing them back to life is addicting...

    Looks great! Just cleaned my rusted tank with Metal Restore and it came out great. Didn't harm paint and let it sit inside for 3 days. I'll be following this post, those blue and silver are so rare in good condition. Good luck

    The blue VFRs are so pretty. Buddy had one right when they came out. Watched him flip it doing a wheelie, then it smashed off of the upper cowl and windshield and then flipped back forward!!! I then watched it ghost ride a half block right into a concrete staircase of a dance club in front of a crowd of people. It was awesome and terrible.

    Good job so far by the way.

    Holy crap - hopefully this one won't end up like that. My wheelie days ended with the '86 750 back in the late '80s, so perhaps not something I need to worry about. Ordered new gas cap and some claptrap for the clutch master cylinder today - should hopefully be receiving toward the end of the week. The goal is to have it at least running by the end of next weekend.

    A quick update:
    • Spent Thursday on the battle of the tank - using POR15; attached photographs (probably the best possible without a borescope) show that the treatment generally worked well
    • With the battery installed, I turned over the engine with the starter

    Next steps:
    • Waiting on POR15 to cure; should be ready on Tuesday morning
    • Also waiting on fuel filter and OEM gas cap (very expensive, fortunately still available) - should hopefully arrive sometime early next week
    • When cured and fuel filter/gas cap are received, will install the fuel tank, add some ethanol-free fuel, and attempt to start-up

    In addition to the above, should be receiving the clutch master cylinder plunger with the fuel filter/gas cap - this will hopefully get the clutch to operational status. With the bike fired up (hopefully not getting ahead of myself here), focus will turn to the chain/sprockets (the chain is FUBAR), the tires ('06 vintage Metzelers) and checking the brakes/adjusting the carburetors.

    Some comments on POR15 (certainly others have more experience than me with this stuff):
    • The tenacity of the material is reminiscent of Duracoat with which I have much more run time
    • The masking process, which I spent three rolls of masking tape on was a waste of time - better to cover the tank with plastic than to use masking tape - there's staining on the exterior of the tank, most likely due to the phosphoric acid reacting with the clearcoat
    • The treatment appears to be generally effective, with the keys being cleaning, thoroughness of the etching, and given the viscosity of the coating, to SLOWLY (as noted in the instructions) roll the tank to ensure adequate coverage
    • Adhesion of the coating appears to also be dependent on a dry tank interior (see photo)
    The 2.5 days of electrolysis were probably extremely helpful given the condition of the tank - I can't see doing this without having pulled out 10 gallons of rust particle laden water beforehand.

    This morning (morning after the application), the coating was hard to the touch and appears to have adhered to the entire tank interior. No pooling was noted. From what I can tell, the coating didn't blind the vent screen inside the tank, though I also purchased a new petcock and low level sensor o-ring and will be replacing these once the curing is complete. Overall, the treatment appears effective, though, as others have recommended, most people should allot a full day (8-10 hours) for the treatment and set aside a dedicated space to ensure plenty of elbow room while operating. I used a shallow plastic container about 2.5' x 4' x 6" to hold the tank. The dirty part comes at the end (I'll be waiting 3-4 days for my skin to slough off my hands to get the paint off even though I went through about 8 pairs of nitrile gloves).

    The bike runs! After the tank cured, received the correct OEM fuel tank gas cap and also a filter. I was able to plumb the fuel filter and add about 2 gallons of ethanol free gas. After powering up and opening the petcock, I could see fuel in the filter. After about 20 to 30 seconds of cranking (10 secs, stop, then another 10 or so secs), she began to fire. The previous owner had fogged two of the cylinders every week, so there was smoke everywhere. With the choke on, the engine was up about 4,400 rpm - I adjusted the idle set and after something of a warmup, I brought the idle down closer to 1,500 rpm. After smoking up my garage, I turned the bike off and moved it outside and it restarted very easily.

    Afterward, I installed the connecting rod in the master cylinder (between the handle and the plunger) and couldn't get any flow: apparently the plunger/seals are bad. I ordered a clutch master cylinder rebuild kit and some spark plugs. Next steps:
    • Install new spark plugs
    • Replace the oil in the engine
    • Replace the plunger, seals, etc., in the clutch master cylinder
    Also, I'll have to read up regarding the carb adjustments to find out if they could be contributing to the smoke - the bike seemed to idle fairly smoothly and throttle response was fairly crisp, all things considered. Besides the above, the bike needs new tires and chain/sprocket. Hopefully there won't e any need for an engine teardown due to worn rings, etc. Stay tuned...

    I have no experience with POR15 but read where it appeared to have affected the paint on your tank even though you masked it. A thought popped into my head that is obviously too late for you, but could be useful to someone planning on using it in the future.

    For what it costs, maybe buy a rattle can of Plasti-dip paint and give the tank's exterior a good covering with that stuff before using the POR15. Plasti-dip dries very much like rubber, and really peals off easily. I have used it on my seat cowl and top of my hard bags to protect the paint from my kicking them when getting on and off the bike. After it was all marked up, I just peeled it off and the paint was good as new beneath it.

    Plasti-dip comes in a few colours including clear. Dries with a semi gloss finish. People here have used it to change the colours on their bikes such as the wheels, just to see what it would look like before they take the plunge and repaint or powder-coat

    Great points and something I'll definitely consider if relining a tank in the future. My feeble attempt with the roll(s) of masking tape didn't quite yield the desired outcome.

    I'm currently waiting on a new voltage regulator/rectifier now that the bike starts up very easily and I've apparently fixed the clutch (overhauled the master cylinder).

    After that, the next step will be to take the bike for a ride around the block then I'll probably be replacing both tires and also the chain/sprockets. The bike should definitely be street-ready by then and I'll concentrate on cosmetics, which include the sagging turn signal stems and sourcing a trim piece for the front windshield - the two clips are there, but the trim piece is long gone.
