    G'day

    I had this GT750 for about 8 years and decided it was time to restore it. I've also decided to attach an old DJP sidecar to it. I was going to do a long winded build report like my old XT600 resto but decided I would restore/build to almost completion before putting up a report.

    Most of the report will be about the resto because the sidecar build was pretty straight forward (done enough of them over the years).

    I decided to use the DJP as it's period correct. Some of you may recognise the sidecar. It was Snayles. I swapped him one of my Ali bodies for the DJP.

    Here we go.......

    This is what I started with. It's a 1975 Suzuki GT750.

    I will put some more photo's on soon. I just want to make sure they are loading.

    I have taken heaps of photo's but will just put up the stage by stage photo's. I won't do a CLANCY and stretch it out:lol3:lol3:lol3

    I tried to do everything myself. Got the frame powder coated. I relaced the wheels. First time I've ever done it. It's not as hard as you think. Most of the parts required have come from specialist shops especially from Discount Bike Spares in England. If you need any parts for old Suzuki GT's they are the people to speak to.

    [​IMG]

    The engine was actually in pretty good nick. All I did was put new crank seals in and pistons and rings. Pistons only cost me $100 for the lot from Cruizinimage. Brilliant website if you are looking for cheap engine parts for old Japanese bikes. Not a big range the big ticket items are super cheap.

    [​IMG]

    Engine in frame. I sodablasted the engine cases and painted it in cast aluminium. Not sure if that was the correct colour but looks pretty close to me.

    [​IMG]

    Getting the gear indicator was near impossible (my was missing) and the one I could find was fairly expensive but luckily I also have a GT550 waiting to be restored which also had a gear indicatior which thankfully is the same part. I wanted to make sure it works and it does, for all gears. I restored the gauges. Trying to get the chrome ring that keeps the 2 halves together is impossible short of spending 100$$$ to get them done professionally so I got an engineering friend to lathe some up out of stainless steel and $20 later and all is good.

    [​IMG]

    After getting everything chromed I have got it to the stage where the motor is almost ready to fire up. Will put the radiator on tomorrow. I put the old tank and sidecover just to see how it came out.

    [​IMG]

    Here is the finished sidecar chassis. I blasted the wheel and got the same bloke who polished my engine cases to polish the rim. Came up real nice. All I have to do now is paint the whole thing. I'm going to paint both bike and sidecar body in the original Gypsy Red, a candy colour. I've never tried to paint with a candy colour but will give it a go. If I fail at least I tried (unlike the Aussie cricket team at the moment:huh)

    Anyway that's the condensed version of the resto/build. Will post more photo's as I go.

    Hi Ray. No I'm not keeping the old exhaust. No idea what make it was. It was too loud anyway (not for me but for the cops:D). It was in bad shape anyway. I tried to get the baffles out of the original exhaust but they are stuck fast but hopefully after getting them dipped for the chroming they will get spat out on the first ride:evil.

    Here's the link to Discount Bike Spares if you are looking at restoring an old GT. He has parts for all models eg-750,550 and 380. Also has parts for some GS's.

    Back to the shed and start preparing the bodywork for painting.

    Great work 3 legs, I have always liked those GT 750 water bottles and the DJP is a perfect match of the time! Don't know how long the resto has taken but it looks like a heap of work! Again great work:clap

    I love those old 2 smoke triples. We also called them stink wheels.But loved their simplicity and in their day they were untouchable (every stroke a power stroke). I had a Suzuki T90 and GT380 in the 70s loved them both

    Did you try lots of heat?
    Or caustic soda? S'pose that's what the chromers will use.

    I've even heard of people dropping some fuel in and attempting to (quickly) burn the carbon off. Not something I'd be attempting, there are braver folk than I.

    Pity about the chambers. Just another example of how a triple is the best sounding engine, as long as the pipes are decent.

    Where is the auxilliary fuel tank going?:lol3

    It lives, It's alive. There'd be fire in them barrels. Started it up today. Bit rough on idle but smooths out with revs. No smoke whatsoever. Just needs a fine tune and she should be right. Mind you, using 3 month old fuel wouldn't help.

    Anyone know what octane fuel to use. I had some 98 ron sitting around so I use that. I think it might be too high. Not sure.

    That's not necessarily a good thing, is it now? :eek1
    On the upside, the new 2 stroke oils really create less smoke than 20 or 30 years ago.
    Pre-mix at the moment? I have clear oil tubes from the oil pumps. If it fails it will probably be whilst I'm riding it, so I wont be looking at the clear oil lines.:huh

    Do we have ANY good fuel in this country? Two strokes have low compression. I'm not afraid of using 91 in mine, as long as it's not got that ethanol in it. I also use 95 and I'm afraid I can't tell the difference in mileage, power, smoothness or anything in any of the cars orbikes I have.

    Hi Dave

    It's under a cover at the moment. I've just started preparing the body work for painting. The sidecar has heaps of holes to fill in so there is a fair bit of work involved. I doubt that I will get it painted in the next month or 2 but fear not once done will post photo's.
