that looks awesome, it's it in as good condition as it looks on my phone? I'd pressure test the crankcases to make sure there are no leaks, then strip and clean out the carbs. I think all the GTs had disks, but the drums look better so just rock that. have a look on dtt, there's a guy who really went to town on his 250. it's a really long thread and all the way through I was thinking "fuck he's ruined it, no it's coming together awesome, oh shit he should have stopped he's ruined it again" cafe racer is the obvious choice if you want to customise it, but for the summer at least, just get it running sweet and ride the shit out of it. Google for info "ozebook" and "sundial forum"

Thanks, might go talk to them at least.

Unfortunately there are no known substitutes, it's an unusual gearbox design. The only new ones are from a place in England that makes them in TR500 ratios and it's something like 1400 pounds

I was so excited yesterday when the courier arrived with my replacement gearbox. Only, it looks the same as the original one with wear on 4th and 5th. I've been told that gears are hardened, but once you've worn through the surface they'll wear really quick. Anyone can confirm/deny this?

I had another look, the yoko is all cracked, the good tire is a dunlop TT100. Let's see if it's still food for 100mph around the isle of man!

For me, these are soooooooo much better than paint stripper http://www.smithandarrow.co.nz/html/Products/Abrasives-for-Metal-5/Poly-Strip-Discs-13/index.html I use the 7" in a polisher, but the smaller ones in a grinder work too, just don't press hard or they won't last.

Thought I'd add a quick update to this.. The bike is completely stripped and I've been slowly cleaning up all the pieces. This should be pretty quick because it's just a bike, but after 15 years in a damp basement it's a fair bit of work. The T500 had a known problem with chewing up the 4th and 5th gears when the oil level dropped a fraction. This was fixed later on by installing a rubber dam in the spot where it would overflow into the clutch housing, and the capacity was increased from 1200 to 1400cc My bike didn't get that fix, so the gears were screwed. Luckily I had a spare motor in pieces which had a holed piston. Unfortunately whoever diamantled the motor put the gears in an icecream container with some water and they got seriously pitted. So after 2 months of searching I found another gearbox in Invergiggle. Also picked up a nos seat cover from England, engine seals and carb rebuild kits from Japan, squish heads from Palmie... Still need swingarm bushings (anyone got some phosphor bronze I can have?) steering head bearings a seat pan that hasn't rusted apart a gearshift lever footpeg rubbers and tyres Hopefully I can get it all back together before the summer disappears.

Congrats on winning the big one. My titan has a sweet yoko from the 70s on the back, no cracks or anything. Half considering riding it but the rubber feels hard as. Might just be good for burnout duties.

I have a lathe, but it's a little myford so only really good for machining struts on r/c cars. useful post this.

?

turbo leone has vented discs

also make sure that whatever moves inside the Bush is nice and smooth cos if it's all rough and rusty the Bush won't last very long

I've read in the past that seam welding requires cert on road cars for this reason. what some people do is get a spot weld drill and drill between the factory spot welds then plug weld them to add rigidity.

I did a welding course at tech, and got a certificate saying I attended the course. Can I now rent my ass out as a certified welder?

I ended up replacing my chinese tig with a used 250A Lincoln inverter for $650. It's liftarc which is a bit of an ass, and I had to make up a box to control the gas so I don't waste it all, but it does a nice job.

good luck, that bike looks mad fun

Had a nasty accident in one of these once in dunedin. good times!

Well I started stripping it: The motor looks nice and big now it's not hidden by all those unnecessary items like the pipes and fuel tank. I can't believe people actually put screws back in when they get this bad. These were on the timing cover: Fortunately the impact driver shifted them. I tried tinfoil and vinegar on the chrome, but it was too much hassle so I knocked together a bath for electrolysis. Basically you buy, steal or make something to hold enough water to soak the parts you want to de-rust. I made a box out of scrap wood big enough to put the pipes in, then lined it with a cheap tarp. Fill it with water then add something to make it conduct electricity. Normally people seem to use washing soda, but I didn't have any around so I used dishwasher powder. Put the item you want to de-rust in, and hook it up to the negative lead of a battery charger. Hook the positive lead to a piece of scrap steel and throw that in the wash too, making sure it doesn't touch the other hunk of metal. Turn on the power, and it de-rusts all by itself. I should have taken more photos for before-after, but this headlamp bowl thingy was pretty much covered in rust: If only it would bring the chrome back .... I like that they put this on the exhaust: Of course I won't!

replace the ignition coil with a12v bulb. turn on the ignition and turn the crank with a spanner the direction the engine runs. when the bulb turns off is when the spark happens so check the timing marks then. edit: duh! electronic ignition now so this may not work

Some head gaskets need to be retorqued, don't know if it's just old ones but when I rebuilt a crossflow engine the gasket kit said to retorque after 500 miles or so. Never had to because someone stole the van before I'd even refitted the carb. Could also be PCV valve stuck causing oil to be squirted into your intake. Check and see if your air filter is full of oil / check the PCV is ok.

I don't have money to be spending on this at the moment so it'll be a slow build. I'm not sure what the bars are off, everything else looks pretty standard. They don't look too bad flipped upside down, so it sets the scene for a bit of a cafe style: I should have a brand new set of chambers in black, but the owner gave me a box with guzzi pipes by mistake so I'll swap them with him sometime. I'll give the guards a bit of a chop and find some small indicators for it, grab some rearsets off a katana or something and ride the shit out of it. I'll stick with the useless drums cos they look so dope. Who wants to slow down anyway? I'm considering lightening it a little with the angle grinder because it's 187kg standard, but not sure I have the heart to do it.

sweet ride. my first bike was a z250 but I kept on having near death experiences on it so I abandoned it when I moved up from Dunedin.

I've seen an sc12 setup where the clutch came on when the secondary opened on the dgv weber. It was a nice little setup.

Just picked this up. It needs plenty of work but I've got most of another bike for spares. It's a 69 T500 Plan at the moment is to strip it down, rebuild the motor, repaint and see how much I can clean up the chrome. It needs a new seat, not sure on shape but it has to carry 2. Give me some suggestions. Like the colour scheme of this bike: so might go for the red/white theme too. I quite like the red frame. I'll just tickle the motor a bit, nothing wild.

needs original white plastic grips and white vinyl seat.
