Pv adjustment help

[finnerz89]

@spanners have you adjusted the lever properly as per the manual? Could just be that it's set up wrong

[declan]

@spanners no it must be 24 hrs the implications are you will burn up your friction material they won’t soak as the oil goes to the sump and does not sit in the clutch cover

[Spanners]

@declan
Oh bugger!

[Spanners]

@finnerz89
The bike apparently had a top end rebuild before l got it so l have not messed with anything to do with that. I will have a read and investigate tomorrow.
Thank you for your help!

[finnerz89]

@spanners you should have about 3mm of free play at the lever as a rough figure

[Calum]

Could be the clutch springs not torqued up properly.

[Spanners]

@calum
I bought a full clutch kit we replaced everything.
All springs are new and we adjusted it to the best of our knowledge and skill.
Maybe the problem was with the repairers! Ha-ha!
Clutch seems pretty solid apart from the power valve, you would have thought if it was slipping, it would do it through all the gears?
I’ll get it up to full speed in 5th to see if it slips, then back to the old drawing board......

[oldman]

It's frustrating innit! Just as you think the end is near something else crops up! Good luck and hope you find the problem quickly,

[finnerz89]

@spanners it's more likely to do it in the higher gears.
I'd follow the Haynes manual procedure for setting up the clutch, then worry about the power valve after.

[Calum]

@finnerz89 It's more likely to do it under load in the lower gears, where the ratios are smaller and you're trying to accelerate. I would have thought.

[declan]

@calum yeah I would agree with that after all it’s where the most torque is

[finnerz89]

@calum in my experience it does it in higher gears when you're accelerating. At least that's what it did on my 650 and 1200

[Calum]

@finnerz89 It'll slip under load. So in the higher gears I guess you will be exerting more load onto the gearbox,

[finnerz89]

@calum yeah. The way I've always checked to see if a clutch is slipping is roll off the throttle in fifth or top, then snap the throttle back open. If it's going to slip then that's when it'll do it.
With a 2 stroke it's obviously a bit different, hitting the powerband would replicate that though I guess.
Much higher load on the engine in the higher gears

[Jens Eskildsen]

I have never soaked clutchplates for 24, nor seen anyone do it.
Just assemle with a coat of oil will do the trick.

And yes, clutches are more prone to slip in higher gear, because the load on it is way higher.

[Spanners]

All! Big thanks for all of your replies and assistance.
My clutch problem was indeed a adjustment issue, half a turn on handlebar adjuster.
I guess soaking them for 24 hours would be better, but according to the Haynes manual not necessary as it just says cover them in the gearbox oil prior to installation.
But god darn it is a rocket for a 125cc! Considering l have a 700cc bike it still made me smile as it squirted up to 70mph! Ho-ho!
But l have to say l had to push her home, l now have another problem!
She died on me......
Starts all fine, put her in gear and she just dies!
What the cluck could be causing this?
P.S l am not gonna give up on this bike now, as it is practically new with all the parts I’ve changed!
Again that’s in advance for all of your help!

[declan]

@spanners usually the kickstand switch

[Spanners]

@declan
Thanks, l found a post from earlier this year with a guy having the same trouble.
Unbelievable a little switch can cause much trouble. Should have a light to say the circuit is broken.
Been years since l pushed a motorcycle home! Ha-ha!

[declan]

@spanners it happens lol

[declan]

@calum it’s playing up again out of the blue I had to blindly adjust pv when I was out got it going properly after a bit went through a bit of water and then it started playing up Again I did wash the bike yesterday so I think it’s probably water the wires for the stator are exposed where they go into the cover Any ideas otherwise
