Variomatic

Have you checked that the battery is accepting a charge? Make sure it's actually not putting out voltage. It could also be that the stator has given out, also check for bad grounds, lose wires, all the usual stuff

Lower displacement Yamahas are kinda known for having this issue, sometimes if you leave them in the sun for a long time on a hot day the fuel pump starts acting up, opinions vary on the solution online, but when this happened to mine last year I replaced the pump and it worked fine. You should be able to find a replacement pump on ebay relatively cheaply, and they're pretty simple to change yourself.

Tried replacing the plug, didn't think it might just be a plug cap. I'll give that a go and see if it helps, it seems in good condition but a brand new NGK part is only a few pounds so won't harm anything to give that a go before forking out for a new OEM coil.

Yep, he's got an imported bike from California(As far as he can remember, the plate it had with it has long since gone missing). As for the repair idea we took it to a local bike shop and they gave repairing it a go, took a while but it's totally oil tight now. But holy Jesus Christ griding it into a part that looked reasonably nice was a pain in the ass, in fact this entire fiasco has been a pain in the ass. Thankfully it's over now

Long story short my uncle is retarded and forgot how to tighten a sump plug, so now I've got to find a sump for a KZ900, problem is anything Z related is like fucking gold dust. Anyone know of a UK KZ specialist that might have one for a reasonable price? We where planning on just having a new thread tapped into it, but it seems the sump is cracked, or at least it apears that way, could be a casting inperfection but he doesn't wanna risk it.

"cheap". Nope. Like jimmy said, you're decades years late. Classic Bike Imports is a good website to gander around, every now and again they have something interesting come in. Other than that the only way you're gonna get a cheap XT or RD is with a load of good luck honestly. You're gonna have to move soon, as soon as the sun comes out again bike prices are gonna rocket.

My bike was being suspiciously reliable lately, it must want something from me, a wash maybe. Anyway, this week after not getting what it wanted it threw all it's toys out of the pram and started stalling, usually just as you go to open the throttle. Not only this but it's down on power (when you've only got 9hp you notice a missing 1/2hp), and under heavy load at higher RPM you can hear the engine breaking up a little, definately not a fuel problem, so I'm guessing the coil is on it's way out. I would test it but my multimeter also threw a tantrum and a new coil is cheaper than a new meter. What do you guys think?

Let's be honest, it's a cool idea but it's basically a fast Piaggio mp3. (Just having a laugh ) Dual front wheels, 3 cylinder 900cc engine, 115hp, adjustable front and rear suspension (from what I can tell from the pictures on the Yamaha website) looks like a bucket of fun. And like Cynic said, it might be a pain for filtering, but I know loads of people who filter on a GS1200 (which I think we can all agree is not a slender machine)

It's kind of a shame, but at the same time the GSXR750 is as common as muck, and in time their will be ones better than factory, just like any other bike once collectors start restoring them, IMO it's better that the bike be used than sit in a garage forever. Nice that it had all the service history, I've got every single receipt for anything my bike has ever had, even down to bulbs and copper washers, it may be an all year round hack but at least it's got full service history.

I was wondering if this was an early April fools but it seems not, at first I thought "Ohh god no", but actually I suppose it's a good idea. A hell of a lot more fun than a normal trike for those who need them, or returning riders, older gents ect. Who knows, maybe they've created a new market like Suzuki did with the Bandit?

That Units gotta be filling up fast, you never seem short of a project Absolutely love the XS, definitely wouldn't have been my first choice to turn into a classic track bike but holy damn it's nice

Only possible solution I can think of is either a kinked line when you bolt everything down, or maybe a metric fuck load of air in the line, all I can think is bleed it again paying particular attention to making sure their is always enough fluid in the reservoir. Sometimes breaks can be a complete bastard, but I don't see any reason they shouldn't have pressure when lose as opposed to bolted down.

Have you checked that you haven't kinked the line? Perhaps when you let it sit loosely it's not kinked, but once you bolt it down it flexes the line and crimps it closed, worth checking that. Something is clearly shifting when you bolt it down, and whatever it is it's got to be quite severe to stop hydraulics from moving. Stupid question but have you checked you actually assembled everything correctly? It's easy to miss a fuckup when you throw everything back together quickly, god knows I've done that before.

Compression on the cylinders (left to right) is 105-130-135 (and yes the valves are sealing and the clearances are right) so the engine was basically fucked anyway but it'd be nice to not have to do that just yet. I tried flushing it with diesel like slice suggested, managed to get a metric fuck load of swarf out but I think it wasn't enough because since it happened the engine has been sounding really sketchy, this morning it sounded ok, but after a short spin it doesn't sound happy, and for some reason the clutch has started slipping (although we think this is coincidental) We're thinking about ripping it apart and trying to make one good engine from it and a spare engine we found on fleabay fuck a fucked gearbox, not sure though. Might be up for sale soon if anyone wants a really fucked XS750?

My neighbor has an XS750, the tacho stopped working two days ago and he asked me to have a look, when I got there this morning I took the cable off and found out it was totally seized (Like not from rust, from fraying and tangling itself up it seems), put on the cable he bought as a replacement and it still didn't work, on closer inspection we found the drive gear wasn't turning. I took the valve cover off and to our horror we found out that the drive gear has totally eaten itself, the bevel drive on the camshaft is basically gone. Now the real problem. All the shavings seems to have been swept into the depths of the engine. Do you think it's game over? I'm guessing a couple of extremely frequent oil/filter changes might save it but I'm not really sure. What do you guys think?
