Gave it a squirt of CRC, got it hot with the hot air gun, sat it flat on the vice with the broken stub between the jaws and gave it couple of whacks with an old axle and hammer. The puller thread bit has seen better days.

I was guessing the crank end was broken in an off. fracture is jagged to say the least.post a pic
PS. Broken axle.........


Actually the crankend internal thread had a odd bolt and large assortment of washers on it, as well when i found it.......I took them off before i sent it,buggered if i know why they were on there? Certainly didn't look factory...........

[husaberg]

Look no more for the inlet anyway......found all the bits will do the measure thing tomorrow..........the inlet actually say 3ln so i are guessing that's what it is
The rotor has lKZ01 on it plus 037 000 2110 11 FZ

Got the bits from Husaberg. The stator and pickup are all good and I managed to get the end of the broken crankshaft out of the rotor. I now know that Yamaha used at least 3 different crankshafts in their FZR250s. The rotor that Husaberg sent has a taper that is 20mm across the large diameter. The one off the crankshaft in the engine is 21.5mm and the good rotor I have off the other engine's crankshaft is even bigger. Still I can get going with wiring and checking the timing of the trigger teeth on the rotor. Both rotors have the same tooth layout so at least something looks consistent.

So, still looking for a rotor.

OK the one still on the engine seems to be marked LKZ23 03700-3060-1YN the inner taper bears the number 51 i never noted what the inner number was on the one i sent you.

Slowly making progress but still need the correct rotor. I know which rotors it isn't.
037000-2110 11FZ LKZ01 &
037000-2660 2KX LKZ12 aren't the correct ones. If anyone has a FZR250 alternator rotor with different numbers on it I'd like to have a chat.

037000-2110 11FZ LKZ01 looks to have the same inner hub outer dimensions so there could be some swapping of pieces to make a good complete rotor.

Husaberg, any chance you could have a look at that other rotor. I have the whole bike together and will take it to the track tomorrow for a couple of slow laps. Not willing to take it over 8000rpm or so with the wrong rotor on the crank. As per the Ecotrons thread I've got it running not too bad from cold and blipping it to about 8K. I'm going to give it a run tomorrow, I just can't help myself.

After that I'll start on the exhaust plumbing for the turbo. I'm at a bit of a loss as to how to connect it all. I think it'll need a reservoir built into the exhaust and I was thinking about 1L. The pipes will sweep left to the reservoir then back and up to the turbo sitting where #1&2 cylinders used to be. I already have the water inlet and outlet connections and the oil to the head is via an external pipe with banjo fitting so that is easy. I've fitted a plate to blank off the crankcases so the oil can drain straight down into that. I'm thinking the plenum will need to be about 1L as well. Someone is bound to have experience with this sort of thing and I really welcome advice and suggestions.

Fitted the regular FZR fuel tank, ran fuel lines, worked all the air bubbles out(I thought) and took the bike to the track for a gentle few laps. Unloaded it and fired it up and immediately thought it sounded flat/off. It sort of petered out and basically that was it. Checked the ECU when I got home and the program load was OK so was pretty sure it must have been a fuel feed problem. I've now jacked up a 4L container with an outlet in the bottom feeding the filter and then the pump. Return fuel tips in the top. Little bit of jiggling round to get the bubbles out and the bloody thing fired up straight away. It may have developed a little problem as it warms up around 40degrees but apart from that it's back to being sharp. I was snapping the throttle to 100% from about 3000rpm and it just picked up real quick.

So, lesson learnt is that it needs a small always-full reservoir to feed the injection pump so there is no chance of bubbles getting into the fuel system.

Husaberg, any chance you could have a look at that other rotor.

Didn't i send you the Number on it? If ness i can whip it into the bike shop and see if they have the correct puller i guess?
But i are in Wellywood for the next couple of days, so it would likely be next week at the earliest.

[speedpro]

You did send the number. Only problem is that I only know what numbers it isn't. Your one is different so it'd be worth a look at the larger diameter of the taper to see if it matches. Sounds like it might be a bit of a pain for you. Rob's down that way soon though and I'm sure he wouldn't mind bringing a heavy magnetic lump back if you could get it off. Actually I could give him the rotor puller I made years ago for these rotors. It was my first attempt at thread cutting on my rickety old lathe. First attempt at thread cutting ever actually. That way you could remove the rotor at your leisure.

I've located some new MB100 cylinders, pistons, pins, and clips for US$30/set. Quality unknown at the moment. If anybody is interested PM me and I'll put an order together. Freight is on top so the more the merrier. I need to check the quality but will also look at supplying a kit to make a bit of power - cylinder, head, piston, & pipe if anyone thinks it might be worthwhile. Should see high 20s I'm thinking. Clutches as I'm using in my bike I can already do on an exchange basis.

[speedpro]

Oook! I've got a cost for shipping 10 on top of the unit cost, and expecting GST on top of all that and it comes to about NZ$63/set - cylinder, piston, pin, clips, and gasket. Those still interested should confirm with a PM, and I'll try and catch the missus in a good moment and drop it by her. Sorry if the original US$30 was misleading.

That price is still a total bargin. Don't suppose they can supply a couple KE125 cylinders?

[speedpro]

Pretty sure they would, I'll check. You need to buy 300 as a minimum but at $1 each it isn't really a problem. The same place also does MB crankshafts. I'm thinking of getting some. I'll let F5 be the first to test one as he is fond of Chinese conrods.

I'm not even keen on Chinese food

it would be worth it just for the crankwheels....... i was thinking of asking you about them but i thought it would be too cheeky

Yes, but I'm not 'They'


I'm part of 'We'.

And We' call it Chinese food.

And its not often very nice. Now the Thais, the Thais know how to cook. Heck even the Malaysians beat the Chinese hands down in the food stakes.

When your national cusine is considerably worse than the Mexicans, who rely heavily on Beans, Rice & flatbreads, then you know that you're a bit sad. People think of Mexicans as lazy, but it isn't a good stereotype esp when the Mexican woman is concerned as their food preperation is quite labour intensive.

Indian food can be spectacular. But its Mexi tonight & now you've made me hungry.

And a little thirsty. but I'll have to go all crosscultural on the beer

but I am going to the supermarket. . .hmm.

That's a lot of gross generations there. BTW ya missed insulting the French, Swiss,Greeks and Italians.
The Chinese (well the ones that can afford a decent diet) wouldn't even serve it to their Dogs....... Oh sorry that's more Korean isn't it.

I am so Hungary i could eat a Belgian.......
Sorry to waffle on a bit..
