Clutch drag

[MarkCR750]

I've got a bit of clutch drag, not major but I can make selecting first a bit noisy!, before I start taking the clutch apart is there any value in adjusting the pushrod, I can't find anything about it in my Haynes manual, the lock nut below is very tight, but before I start using heat etc has anyone adjusted this with good results?, thanks Mark .

Before you do any more, are you aware that the pushrod adjuster is left hand thread, which will break if you keep trying to "undo" it by the usual anti clockwise way!

[MarkCR750]

Ha, no wonder it was tight! , (well it is now), thanks Hairygit, I knew there was something amiss as a locknut shouldn't be that tight so I stopped, perhaps it was too early in the morning for me to think that it might be a left hand thread!, anyway thanks again you've save a lot of swearing and crying at this end.

Ignore what I said about the left hand thread, closer inspection of the pic you posted shows it to be a conventional right hand thread, I got muddled with the adjuster on the C50/70/90, which IS left hand thread.

No worries, I had just tried and there was a slight click of movement but it felt like it went tighter so I stopped, had a look at photos of second hand ones on eBay and yes definitely R/H , think I'll try some carefully applied heat to the locknut.

[hairygit]

Using heat may damage the oil seal in the casing, so be very careful going down that route! Probably better to try and stop the arm moving forward while undoing the locknut, for example using a pair of mole grips to hold the arm still.

Yeah I was using a soldering iron directly on the nut, so far I've tried penetrating oil, heat, filing off the burrs at the edges of the slot on the screw thread, very gently tapping the sides of the slot towards the centre of the thread in case it's splayed outwards, making a screwdriver bit to perfectly fit the slot, it's sunny though so stuff it I'm off for a ride, I'll try immobilising the arm when I get back later cheers.

If you get the lock nut sorted the adjustment procedure is described in the CB750 Shop Manual in the Cb750 mega download in Ash's Dropbox (p183).
It might not solve your problem but at least it will tell you how Honda says it should be set.

if you going for a ride might see you at CMC clay cross, I will be there later around 12.30 / 1pm ish

[MarkCR750]

Ok I had 1 last go, wedged the arm with ally blocks, success, I was being an idiot trying to stop the shaft rotating with the screw slot, anyway I've turned it in three quarters of a turn and clutch drag is gone, I'll get off for a ride now and see if the clutch slips cos 3 quarters of a turn is probably a lot , thanks Hairygit for saying immobilise the arm.

Not going that far Greebo, my wrists are complaining quite a lot!, it really does remind me of why I sold the blade,  I'll just go 10 miles or so to check out the clutch, then have a week on my other bikes whilst my wrists repair!.

[Greebo]

I noticed how your clip-ons are well turned in obviously because of the fairing, but I think that must be the problem for you....mine are set more straight & I don't have any issues with my wrists...I did think I might have some discomfort at first cus I am riddled with arthritis, up to now all is good wrist wise, no problem with the neck, just got an issue with the left hip aching after a few miles,  going to get that sorted out the back end of the year.

I will do anything to stay in the saddle for a few more years..

[MarkCR750]

Ha yes, nothing more important than riding, all bikers prove this by riding in the first place , given the dangers, I can get the bars a bit more turned out but I'll have to move the choke pull, I used to suffer on the blade though so I think it's just old age (it's not the age it's the mileage 😀), I'll have a look at moving the choke later today .

Had to pull over and readjust the clutch, slipping like mad , turned it back out half a turn and seems good now, I'll have a look at setting it properly later as well, still clunks a bit going into first but I'm told they all do that!, doesn't try to creep forward now though.

[MarkCR750]

Well I didn't move the bars Greebo, I had remembered wrongly it's not the choke pull but the clip on clamps that foul the top yoke, I would have to drop them down the legs an inch to get more rotation and I'm pretty sure that would put even more pressure on my wrists, anyway I've been busy removing the girly round bit from the gear shift cover, turned out OK IMO but doh!, I just found one of the cover location dowels on the floor when cleaning up, had a bad day today ! (It's staying off!)
PS I'll have to reroute the loom at some point to make a tidier job.
