Hiya folks.
I've recently acquired a nice XBR and I love it. I have a query though. When I start it up, the first time I stick it in gear it goes CLACK! like I've knocked it into grear without clutch. After that, gear changes are fine. Is this a common thing? Is my clutch knackered? Any ideas?
Cheers,
Dave

Sounds like sticky plates, I'd try an oil change and make sure the front brake is on first time I engage gear in the morning ;-)
You *could* open it up and have a look at the plates but if it were me, as long as it behaves the rest of the time I'd just ignore it and crack on :-)

Easy things first, perhaps you have too much freeplay in your clutch cable and the excess slack needs adjusting out. Or maybe your engine idle speed is set too high.
If they are ok then yes the clutch plates are dragging, might be clogged up with gacky old oil residue,might be able to strip down and clean off plates with a solvent, but while you have got it all apart might aswell fit new ones.

My NX650 does that, but only if the rev's are a little high as I'm still on partial choke. Find sitting there with the clutch held in for 1/2 a minute helps, or wait till I can leave her on normal tickover. gets worse if she's a little low on oil too, infact clunky pull aways normally alert me to check oil level

Thanks fellas
Its just had oil change and oil filter and I know the previous owner changed the oil very regularly. I've done the obvious noodling with the clutch cable adjustment etc but no joy. Also, letting the bike warm up before I go anywhere doesn't seem to help. Tickovers pretty low too - I don't think its that. So mucky/worn clutch plates seem favorite then. Cheers for the help.

Aye pigafetta,
Give it the old Triumph treatment.
Before starting, pull the clutch in and spin the clutch over on the kick start. Just breaks the oil film between the plates. Works well on the SRX.
If you do decide to 'strip' and plates are within tolerance for wear and not warped, degrease all plates with brake cleaner, remove burrs from drive lugs/tangs and buff out any 'picky' bits on the metal plates with Solvol, cleaning off with degreaser afterwards. Remove any burrs from the clutch drum as well.
Cheers, Bill

Ignore the worriters, it's normal. All GBs do it, so I'd expect XBRs to do it, too. Nothing to worry about.

Thanks all. Much appreciated. The kickstart thing sounds like a good plan. I'm not gonna strip the clutch for the time being anyway and see if it gets worse or not. The bike is running lovely at the moment so I'll leave well alone.
Cheers.

Aye Dave B,
Final sentence in your last post says it all.
Cheers, Bill. ;-)

Not just XBRs, most Hondas seem to clunk into first. Seems a small price to pay for solidly engineered pinions, wouldn't all you SRX boys agree?

Point taken, last time I saw pitting as bad as on my SRX 5th (20,000km since the previous one) was in the BMW R100 I had a few years ago. Now it had the worst of both worlds - majorly clunky box that fell to bits regularly........
