    ben, the primer and top coats need to be compatable so what top coat are you using? the paint supplier will recommend. just use a good etch coat first.

    You should glass bead blast aluminium. Sand blasting is too abrasive and will remove metal. You can just take your aluminium parts that you want to be polished to a metal polishing business and have it done professionally.

    Hey Blair,

    Yeah I can do that for the engine covers, all good there. But what about in between the fins? I need to get rid of all the rubbish on the surface before I paint

    Get some etch primer onto the bare metal as quick as possible, the sand blaster should have done it straight away. Try not to handle the metal too much, use gloves. etch prime lightly first, then a few good coats of a primer, even sand between coats to fill any imperfections then top coat with a few light to moderate coats to avoid runs.
    Be very careful with the engine if your going to sandblast it assembled, only takes a couple of grains of garnet to destroy an engine if any gets in. Take the head & barrel off if you can, your going to this much trouble anyway, that way you can be assured the engine will be ok. Nothing worse than an engine blowing when your at high revs & high speed ! It just ruins a good bike.
    Get a quote from your local panel beater to do the frame & tank with 2 pak, some of the acrylic laquers just done handle petrol on them.
    Keep up the good work

    I've found an automotive painter with my vision in mind, he is going to paint the frame, engine and rims for me. He's sending a primer so that the sea air doesn't surface rust the frame too much in the meantime.

    Does anyone know of a carbon fibre supplier in Melbourne? I want to make my tail and seat pan on the weekend.

    Just had a thought, maybe a tail loop should be made? Benefit being I can attach things like brake lights and license plates right?

    carbon fibre cloth is sold where they sell fibreglass and you need the 2 part epoxy as well.to get the shine you need to have a waxed mould..

    Hi guys,

    Thanks for sticking with me you've all been so great with your advice and help. Its been a short wait for parts around silly season, but my rear shocks and seat pan have arrived. The seat pan is listed as a "ducatti SS style" and I think the flat trim on the sides almost matches the gsx tank.

    When my tail loop arrives from Mostyn in brisbane i'll measure up what I need to make the support for the seat. With the leather on the pan to widen the rider end a touch it should match the tank really nicely.

    What do you think?

    Nice work, gunna be great
    The carbon fibre adventure was a bit eyebrow raising, its expensive & a **** to work with.
    Good to see the primer, just be careful not to get any oil or silicone or anything on any of it, wrap up the tank at all times, keep it dry & away from oils & sprays.

    Alright, so christmas holidays are over! Time to get building again

    I'm headed down to a workshop called Kustom Kommune to use their sandblaster, griding and polishing equipment and hopefully someone can help me weld the back of the bike together. I'm going to sand and polish the forks, engine covers and blast the brake caliper. I'm sandblasting the engine as I couldn't find anyone with a high pressure water process to take off the corrosion or the clear-coat. I'll then paint the engine and mount it back in the bike

    I need to find someone who cuts aluminium to size so I can sort out this seat pan, that way I can attach the tail end, get the frame painted and get the upholsterer booked. The exhaust looks to be coming from Japan next month as i'm out of cash, but its a stocky short pipe that goes under the bike with a muffler built in, and its matte black.

    Some parts arrived over christmas:
    Master cylinder, bearings for wheels and steering, rear shocks, tail lights, light brackets front and indicator brackets front, pod filters

    On the way:
    Clip ons, guages, throttle grip, switches, mirror

    To get:
    Exhaust (webike.net) indicators and switches, new headlight, brake line, ignition, foot pegs, tires, engine bolts,

    Looking forward to getting this finished!

    good update Ben, looking forward to hearing how you go at the Kommune, I saw the crowd sourcing request to get the project off the ground, it seems like a really good idea and I wish we had one in Brisbane.

    It's begun. I tore down the head yesterday. Let me tell you why...

    So Jimmy and Richie at KK were extremely helpful. After some deliberation and deciding that the whole block won't fit in the media blaster, I decided its best to do a teardown of the head. It's not a complex bike and its going to be easier to enamel and bake the individual parts for the paint. Also I can be sure of the state of the rings/pistons/valves for tuning later on. So I excitedly flung the manual open and got started.

    Good news! Its not a lemon. The rings and bore are in great condition with no scoring, the valves all seem to be fine with your standard carbon and flaking. Wouldn't hurt to replace them so I might do that. Piston heads need a wet/dry and some carbon cleaner, thats it for them. And the rings all look to be in good condition.

    Bad news, someones been in there before and stripped a few screws, that was a headache. I need to get some replacements before I can continue.

    Now to blast parts/ wash them all (on the fins) and start the enamel spray. Remember the engine covers L and R and sprocket cover are going to be polished.

    PS Check out the before and after shots of the header cover after a light blast with the media gun

    And check out how my forks came up after a light sanding with some steel wool and then wet/dry

    AND check out how my covers came up after a buff!!!!

    (sorry i'm just really stoked)

    Making great progress there mate .... it will look tremendous when its all glued back together.
    Taking the time with each individual piece , even the small things, makes it worth it when it is all together.

    Give those covers plenty of metal polish as apart from the shine it will give them some protection from the elements.

    Hey Ben
    Well done, I am a tad surprised by your reaction to the status of the engine, this is a Suzuki, one of the finest motorcycles, extremely easy to work on with what some call ( bullet proof engines). The tear down and blasting of parts looks great, think your bike is going to be a WINNER!!!!

    Good job, now you've got the bug that'll last a lifetime.
    Keep the updates coming.
    Valves are expensive, talk to the mechanics about just lapping them in again, they should be in good condition

    Top advise there, valves should be OK.

    Got home from polishing my covers, I can almost see myself in them. Too many deep gouges to get back to original, but it kid of adds character a little whilst still looking "cared" for.

    Yeah, but as this is my first ever engine/bike and with some obvious work done previously I wasn't sure what I was to find AT ALL! It's been such a good project


    LOOK WHAT ARRIVED WHEN I GOT HOME!!!!

    So my rec reg is stuffed (said the guy who sold me the bike) and a new one is going to set me back $100, wrecked and shipped from the states or brand new. The later models seel to be a different shape and the pins are in a plug instead of free like mine, so i'm not sure if they'll work, but they are half the price

    I did find this reg/rec however:
    http://www.shop.modernmotorcyclecom...ator-rectifier-12-volt-200w-single-or-3-phase

    I was wondering if (Dave, Grey, Lite, Kiff, Will) any of you had any experience with whether these 12v rec/regs are pretty standard or not. All the wiring looks to match, and in the manual it gives me test voltages for a multi-meter but I don't have it hooked up to test anymore.

    Any tips guys?
