What alloy does the MT9 engine use?

I'm not very optimistic about anyone being able to answer this, but I was wanting a welder to weld flanges onto the (badly rounded off) exhaust ports of the cylinder head (so I can use proper steel bolts instead of aluminium thread, and what moron ever thought aluminium thread was a good idea?), and...

Re: MT-9 Headstock steering bearings question

< ...grumble... > Yeah, you're right. Aluminium's soft. It wouldn't last long, and then I'd have to pull the whole damn thing apart again. I'll take it around the welder's tomorrow, tell him I'm looking for a fit that needs to be tapped on with a hammer. I'll also get him to do the same with that be...

Which is tighter than what I've got. Maybe if I wrap a strip of aluminium foil around it, to bulk it out a little...

Re: MT-9 Headstock steering bearings question

What benefit do you feel the ball bearings give over tapered rollers with the sidecar? Because the only difference mentioned online is that ball bearings have less resistance and are therefore better at high rpm, while rollers have a bigger footprint and so are better dealing with more weight. Since...

Re: MT-9 Headstock steering bearings question

Good question. I bought them from sidecar pro a couple of years ago, so I can't remember any details, but looking at his site, and the numbers on the bearings, it's these: http://sidecarpro.com/BFA-tapered-steering-column-bearing.html He told me it would also suit my bike. So the internal diametre o...

MT-9 Headstock steering bearings question

This may seem a stupid question, but how tight should the steering bearings on the steering rod and bearing nut (aka "Jesus Nut", for some obscure reason) be? I pulled my headstock apart when I noticed how shaky the front was under braking and tightening the bearing nut wasn't helping (I could tight...

Re: Oil Leaks, Dodgy Charge Lights, And Lost Posts, Oh My

Is there any easy way to check if the crankcase vent is blocked. I'm assuming it's that tube coming off next to the generator. I tried blowing and sucking through it (not while the bike was running, obviously), and there was reasonable resistance, but I could do it, but I don't know it that's a wort...

Oil Leaks, Dodgy Charge Lights, And Lost Posts, Oh My

NOOOOO!!!! This bloody thing ate my post! :shock: I had a long, descriptive (maybe a little rambling) post, and it's gone. :cry: Took me like farking hours... OK, I'll re-write it, but massively abbreviated. Long story short--On a ride, had distributor trouble, ended up riding home 20kph on one cyli...

Re: Proper Oil pressure for Dnepr MT9?

Sorry for not getting back sooner. You know, Christmas, hospital visit for surprise abdominal surgery, the usual. And thank you for the oil pressure information. Managed to get another engineer's appointment, at which point he told me that he also wanted the seat moved back 40mm, and one of the rear...

Re: Proper Oil pressure for Dnepr MT9?

Well, got the gauge and had a measure. That was interesting. First, a little background. The reason for this will become apparent later. (Flashback) The PO (previous owner, I believe?) at some point tried to convert it to 12V, but quit part way through. I reverted it back, by getting some parts and ...

Proper Oil pressure for Dnepr MT9?

Does anyone know what the oil pressure should be for a Dnepr MT9? And at different engine speeds? I was about to take my restoration to the engineer's for approval, and found my oil-light lighting up when accelerating and at road-speeds, but no problem at idle / low revs. I'm buying a gauge to check...

Re: Grinding noise in gear

Update Time! The clutch plates were in backwards. I found a You Tube of someone taking a K650 clutch apart and paid VERY careful attention. Ordered some new plates, waited very patiently and totally DIDN'T check the parcel tracking twice a day every day for weeks, despite what lying liars who are ly...

Re: Grinding noise in gear

Oh, what the fark?! I am going to hunt down and kill whoever the arsehole was who had this bike before me! :machinegun: Some of his innovative solutions were amusing, like how he had decided to convert it to 12V, so he put in a car alternator, and hooked it up to the gears using a bit of garden hose...

Re: Grinding noise in gear

A can of silver spray paint and a star stamp will run about $10, to some questionable sellers, that would constitute a "Rebuild" and upgrade. This is true, but there comes a time when you've just got to trust your supplier. I dropped one or two who I didn't, but I like Magnus . He's given me no rea...

Re: Grinding noise in gear

Don't remember. I'm thinking about it, and when it's in gear, but the clutch is pulled, is the only time when the engine-side and gearbox-side parts of the clutch are moving at different speeds to each other. When the clutch is released, then they're obviously joined and moving together, and when it...
