    Ah yes but Lego bricks are made of ABS, you melt them in Acetone to create a plastic putty

    This then melts in to what you are fixing and becomes part of the original,
    ABS molecular structure comes apart in Acetone and as the acetone dries out the Structure returns to how it was originally

    So you can make your own plastic parts using this method, tricks learnt from 30 year old Porsche restoration, if you thought Honda parts were expensive think again

    There are several methods of working with ABS or even "welding" it or mixing in fillers. Probably no wrong answer, depends what you're trying to accomplish/repair. The plastic epoxy is closest I've found to be ABS-like and easier to work with, no harsh chemicals necessary, good working time. I'd suggest you go get a syringe of the epoxy and add it to your arsenal, it's very useful... stick to the Permatex brand, not JB.

    well had an hour or two today, so went to the garage, 5 litres of Shell Super Unleaded, carbs back on, new fuel filter, secondary fuel filter, fitted by someone else,

    battery is charged, and she burst into life after a bit of cranking, to the carbs time to fill, now running on all four and sounds pretty good, discovered what the random switch is for, the rad fans, so whats the solution for the fan switch as I cant buy a new one anywhere?

    Is there a replacement for it, from another bike or car?

    The direct radiator switch is a pretty common mod for many V4 Hondas, Interceptor, Magna, Sabre, etc. If it works, keep it at this point. If not, any 2 pole switch should work to replace it.

    Bought my VF500 new in 1987, had many riding friends with V65, V45, etc. then and over the years. Never did a single oil and/or cooling mod to any of our street bikes. They all lasted well bey0nd our use. The bits of "must do" mods, folk lore, etc. never cease to amaze me about Honda V4s. Take it all with a grain of salt IMO.

    I have bought a new thermostatic switch for the rad fan,

    I would rather have it how it should be, I can see me forgetting about a manual switch

    Wire the switch in parallel so you can also turn them on earlier, it can be nice to have control.

    Took the top part of the fairing off today

    [​IMG]
    Left hand indicator mounting point, bit broke but serviceable

    [​IMG]

    The right hand side, missing with half a hobby box glued on with hot glue and silicone, time for some drastic action

    [​IMG]

    Start by forming a frame with some 3mm ABS sheet, I borrowed a hot air plastic welding gun

    [​IMG]
    Fit a back plate and get the cordless Dremmel out and get some shape to it

    [​IMG]

    A little prep and some fine filler, and some Meteor Grey paint and it’s should be good to go

    Some gorilla glue on the inside of the screen, managed to get that off, the screen will clean up nice with a DA machine and toothpaste

    Taken ages but I have managed to plastic weld nearly all of it back together

    Even new tabs on the rear frame

    So I have ventured out on to the road on the bike just to test the brakes after testing the brake fluid and discovered it was 11% water,

    Anyway it seems to run ok ish, below 5000 rpm, but that’s as far as it will rev, it just goes into misfire meltdown,

    It also seems very rich all the time, think the carbs will have to come off again and get another cleaning out,

    Does anyone know when it switches from slow to mains in the jet department,

    And it’s booked in for a MOT on Saturday the 29th, time to find out what else I need to fix,

    Impressed with the insurance cost of £58 full comp

    possibly non-working carb diaphragms if it won't rev over 5k. take off air filter and see if slides all rise equally in response to throttle inputs with it running.

    how did you decide it's too rich ? did you drain and flush the petrol tank out ? any signs of rust ?

    I did not take any of those off when I cleaned out the carbs first time, I will have to take a look, thanks for the pointer

    I have be careful as the needles are different in the rear carbs I have read somewhere

    Is it possible to buy new diaphragms? If so where would you suggest

    i recommended a test for diaphragms, and since they often don't go back together properly, i don't recommend taking them apart unless they fail to rise. new ones are available in your country from jbm industries, but fitting them isn't so easy.

    Yes indeed that’s what I meant by take a look, use your recommended test,

    It seems to pop in the exhaust on tick over and I can’t get the tick over below 1200 even with the idle adjust screw right out, so I have something not quite right, I really appreciate your time to help me out a bit with suggestions

    My 1990 carbed ST1100 was a resto after being parked up full of fuel for 10 years. Once I got the carbs, tank and fuel pump working I had a misfire above 4000 rpm. Pulled the carbs 6 times but no improvement. In my case the fault was corrosion in the plugs that fed power to the right switch pod and back to the ECM, low voltage resulted and hence poor ignition at higher revs. If you've not already done so, try pulling the connectors and cleaning them. My bike also responded well to some nice new spark plugs even though the old ones cleaned up and looked ok.

    How much do you want me to dismantle, just the air box off or carbs off the bike

    I don’t think I will have time to remove them tomorrow, the wife has plans for me “groan”
