Clutch Basket adjustment help please

[DahDit]

Oh fonts of all knowledge.....

Paul, our son has got his 18th birthday present a little early to allow him to enjoy the off term time and build up some experience before the bad weather arrives. It's a YBR 125, very low mileage, fresh oil.

I've setup the free-play at the lever, the clutch operates as it should whilst driving away with a nice light action, but there's a couple of issues I hope y'all could help me sort out.

1. Neutral is a bugger to get. Going from either 1st or 2nd to neutral takes a wee bit of force to move the gear lever and you subsequently tend to pass neutral and end up back in gear.

2. With the bike on the centre-stand, clutch lever pulled back and 1st engaged, the rear wheel will spin from the clutch dragging with sufficent force to make it uncomfortable to stop the tyre with a bare hand. There's not enough clutch drag to move the bike's own weight however.

The above to issues I hazard are most likely a result of the same set-up issue I guess.

I'm planning to drain the oil and take the clutch casing off. The bike is Chinese made (as are the Honda CBF125's) so I've also got some EBC friction plates and some new steel plates on order which I may or may not replace the OE whilst it's exposed trying to fix the issue.

I'm just after advice as to how to adjust the clutch basket (locknut & pushrod?) to eliminate this drag when it's in gear.

Rgds,

Neil

Most Chinese bikes are Honda based engines, I've have a few , currently a 250 Skyteam, based on a Van Van which is a Suzuki with a Suzuki engine from Japan.

If the rear wheel turns then you simply haven't got it adjusted correctly, and I have to say finding neutral is a sod on many bikes but it shouldn't be that heavy either.

My Aprilia Mille has a quick shifter but can still play up finding neutral, which may have contributed to an accident I had on a Futura , which the same engine box. I hoped the Futuras successor a Cagiva 1000 with Suzuki engine box would be sweeter, however maybe due to new replacement boots I have to ensure my big tootsies are positioned right to find the next cog, then it is.
Ironically the Chinese bike has one of the best gear changes experienced on any bike owned.

This is a Yamaha YBR and like the Honda CBF they are both Japanese name bikes made in China. It has a Yamaha designed engine..

Unfortunately it's not just "simply" mal-adjusted. If it were easy to remedy by either the lever adjuster or cable free play adjuster all would be peachy.

What oil have you put in it?

Other than that, I have heard that the gear change mechanism can be bent and cause gear change problems.

The bike only has 700 miles on the clock, the oil was as supplied by the previous owner. I will be using 10w40 synthetic when the case goes back on.

It will probably get better with more miles then,

Could just be sticky clutch plates,

Don't think there is any 'adjustment measures' you can do to the locknut/pushrods mechanism in the clutch other than checking the torque on the nut of course, could have worked loose ?

Think they are fibre friction plates so if oil is the problem, which I doubt, with that sort of mileage, may be worth changing if you've ordered some. If it was mine I'd just try an oil change and perhaps have a play with the positioning of the gear change lever itself before stripping the clutch. Just another thought, but the chain tension is ok ?

Good luck and keep us updated.

Ps, 18 eh? Bloody 'ell, doesn't seem two minutes since he was learning to ride a pushbike!

[DahDit]

OK, I was wondering if there was anything that could be backed off regards the pressure plate to remove the dragging.

The gear lever has been adjusted so that it's in the right position for him, it's got full, free movent. Chain is adjusted too.

I'll give it an oil change first before opening the case then. Thanks Gents.

Yep, 18 in October... Gulp.

Looks like an oil change has improved things - he's gone out for another ride tonight so we'll see when he comes back.

Either way he's loving it! Passed his CBT on Thursday last week and he's been out every day for a ride
