Yes, I’ve got a couple of historic bikes already, very satisfying when the tax comes up as “Amount due 0.00” isn’t it these are they, any excuse to show a photo!
V straightforward in that case . If you have the German equivalent of the V5 you don’t need the dating certificate . DVLA will keep the German doc so take a copy if you want one for the history file
R40 is for 4 strokes , R30 is for two strokes , and if you want the lovely smell ,just put a teaspoon full in the tank .
Snags so far; Clutch dragging so much it stalled the engine when put into first gear Fix- Pushed the bike up and down the driveway a couple of times pulling the clutch in and out, eventually it freed off, doesn’t drag at all now, I have now oiled/greased the clutch actuator, oiled the clutch cable, changed the engine oil, the clutch now seems good (but I’ve only ridden in 1st on the driveway so far). Front brake light switch not working. Fix- disassembled the switch, removed 40 plus years of crud, made a new bridging contact, now works fine. Clutch lever clamp bolt broken Fix- fitted new clamp bolt Engine very smoky on startup. Fix- 2 stroke oil in CCI tank siphoned out, a clear thin oil, might’ve been 2 stroke oil, might’ve been 3 in one! , I replaced it with Silkolene oil designed for CCI, now much less Smokey, not sure if the oil check valve for the RH cylinder is sticking a bit though, still seems to smoke a little too much on the RH exhaust on startup, it soon clears so I’ll leave that until it’s been run on the Silkolene for a while and see what happens. Left rear indicator bulb blown Fix- replaced bulb. Indicator switch, the bit you press was missing Fix- made one out of a lump of black nylon, need to source an original item Loads to do but so far no nasty surprises, not saying there won’t be any!
Good luck with the project, great little bikes, I loved mine until it was stolen from outside night school. Keep the pictures and updates coming.
Mixed memories, had a mate back in 79 who had one. He upgraded to an X7 but tragically was killed on it.
It was the Gt range that first got me into bikes, one of my sisters boyfriends had a GT 185, i will never forget my first ride on the back. I went out and bought a GT50 as my first bike.
Today’s improvement was to fit a sidestand, it was killing me lifting it onto the centre stand!, designed before they invented the “step on lever”, couldn’t find a GT250A one so took a punt on a cheap GS750 one , fits perfectly! Also I took it for a quick 1st and second gear ride on a “private road”, the smoke has cleared up, must’ve been all the starts & running on tick over that was causing a buildup of 2 stroke oil, anyway a successful day, now she’s in the garage having a rest. PS the wooden blocks are there to keep it upright, it gives me more space to walk past in the garage.
The front brake was dragging a bit, so I disassembled the calliper, sliders ok, pumped the piston out a bit, looked good, then it wouldn’t push back in again!, put a clamp across it, felt hydraulically locked, this must be a master cylinder issue I thought, anyway I undid the bleed nipple, pushed the piston back, then bled the system, now it works perfectly, my best guess is there was a blockage in the oil return in the master cylinder that was dislodged when I bled it, anyway it works now so that’ll do!.
Mine was quick but the crank couldn't cope with the power. Ran 34mm Mikunis and was flat as a fart until it hit around 8k revs then hard and fast round to 11k plus. Frequently followed by a loud knocking as another crank bearing failed.
Today’s improvement was to put the battery on charge , I’ve checked the charging system with a multi meter and it works (on a 45 year old selenium rectifier), but I’m not riding it so giving it a boost.
I like to start with “today’s improvement” but today it’s “today’s bodge”, temporary repair to the fork stanchions before sending away for rechroming in the winter, I’m fitting new seals tomorrow so that I can get it MOT’d in a few weeks time. Several pits in the chrome which have sliced the seals causing the forks to leak. Fix - Go over the edges of the pits with a fine oil stone, and then 1800 grit Emery paper, then 2000 grit to smooth the edges. Mask off then apply Araldite, smooth down with 1800 grit then 2000 grit. The end result is visible but absolutely smooth, it’s impossible to feel the repair once it’s smoothed so the new seals when fitted should be fine, here’s all the right photos, not necessarily in the right order.
Doh, the fork seals are the wrong depth, I’ve contacted the seller, the ones they sent are 10.5mm deep but the ones in my bike are 12.5mm deep, I’ve emailed the seller.
Did nowt today but found this useful link , putting it on here in case anyone else gets a GT250A, plus there’s some interesting stuff on other old Suzuki’s on the homepage. https://www.oldjapanesebikes.com/mr...YFgPRe_Lavml2QQAgLSHQaOo1oj6iLhUfo4WlVAKWGfsc PS if you’re using a touchscreen you can just tap between the pages in the manuals.
I seem to remember that the GT250A was faster than its ram-air predecessors (or the T250 Hustler before them) and had the effect of being the last straw that broke the camel's back, helping to trigger the massive change in the law that stopped 17 year olds from being able to get a provisonal licence and getting straight onto a bike that could do around 100mph. Suzuki had form in this area having belatedly brought out a "moped" faster than the FS1E (Suzuki AP50 -faster?), and 50mph "mopeds" for 16 year olds didn't last long after that.
I think all of the 250’s of the time we’re too fast for 17 year olds (with the exception of the superdream which was of course too slow ), the successor to the 250A , the X7 was very nearly a true 100mph bike, but from memory it was the Yamaha RD250LC that really was the final nail in the coffin as far as the law makers were concerned.
The Fizzer that was faster than an AP has never been made. My red Suzuki sixteener ate purple horrors for breakfast! LOL.
