PM sent! I’ve not managed to remove the stator despite struggling with it. I think I need a superfine thread on that 10mm bolt, nothing I’ve tried so far will engage.
A spare engine will see me right I think, there are so many issues with what I have that a build of the 2 would be ideal.
I have found somebody who can rebuild the crank now, but until I know I can see the engine through the rest of it will have to wait.
Also, heretical I imagine, but there must be a front end swap from something more modern that will go on? I’m not interested in originality, I want something to use and those1970’s brakes are truly terrifying, esp in the wet. And the forks on mine are also yet another ruined item!
Anyone any ideas? Single disc, modernish forks, similar geometry. GN250 maybe?

Like this you mean~
(Clicky Linky)
My mate's take on a GT200/SB200 hybrid. Remember that a GT200 is basically an upgraded SB with 5 gears.

Note the colours and you'll understand the name on the tank.........

At Grampian Engineering (Another clicky linky), they completely strip and rebuild a GT185 crank while you nip down the road and have a breakfast. Good prices too. They also do T500 cranks and triples as well.

That looks useful and fun, Put some ace bars on it, a pair of expansions and it’ll look a bit like the crayon drawing I have up in the garage to guide me through the rebuild I’m doing!

just checked the thread in the end of the rotor and it's an m10 x 1.25 thread. same size and thread as the bolts that hold your brake caliper on. to remove the rotor you will need a bolt with at least 30mm of thread to reach the end of the crank and start pushing the rotor off :up:
cheers, dd.

Excellent tip! I’ve rushed out to the garage and whipped off the Caliper bolt....looked promising, but it just won’t engage with the thread no matter how much I try. It looks and feels too big. There’s plenty of thread though it does look a little stressed..
PM sent!

I think it's the same thread as the front? wheel spindle too. I just cut a piece of 8mm round bar that I had spare, popped it in the hole in my 550 crank and used my wheel spindle to pop it off. Just 'nip' the bolt, then twat it with a rubber/wooden mallet and off it plopped! Similar technique on yours.

hi alan, i think you'll find the front wheel spindle is m12 fine. having said that, there are 3 different rotors [and probably stators] for the gt185. ignore the part numbers, they are different. the 2 i've got are both m10 fine, so it looks like his threads are knackered :(
cheers, dd.

Must admit, I haven't stripped a 185, but thought that the smaller bike would have smalker wheels and possibly a smaller spindle, it would still do. Mebbe not then, but always worth a try.

Yep worth a try and all good ideas welcome. I’ve taken the spindle out and tried that, too big. Felt the same as the caliper bolt, in that it’s absolutely not engaging, but also not ‘snarling’ (technical speak for not fking it up) with the thread. Really frustrating! It must be a smaller size, I think DD said there are 3 different stators (the big delicate heavy thing with the copper windings whaever) this maybe a very late model just before the X5. So....
I’m confident the thread is intact though bruised, but wtf size is it??

have you thought of running a bottoming tap down it? you've got about 30mm depth to play with. still reckon it's m10 fine though. perhaps some peasant has tried tightening an m10 coarse bolt into it? get it sort of back with a proper sized and threaded tap. there again, you could always [carefully] helicoil it :D
cheers, dd.

Yes, that’s what i’m trying to shortcut by asking, but I think I’ll have to get a good set of taps and dies to, literally, get to the bottom of it. All part of the fun though, and why I bought it in the first place!
