Pv adjustment help

[Calum]

@spanners Sounds like either the chain, or the clutch is slipping.

I had a mate with a 2001 DTR said the same thing to me, didn't realise the chain was spinning on the front cog believe it or not. I took it for one spin up the road and was like F me mate that is deadly. If it slips and coils up Bye Bye engine as the chain smashes the crank case together.

If you've put Castrol Magnetec oil in the gearbox, the clutch will slip.

@calum
Thank you again for all your help!
The clutch plates changed when l had the water coming in the gearbox from the water pump seal, could be a bedding in issue?
Both sprockets and chain brand new, changed as a full kit.
Oil in gearbox is Rock oil lite, bought from Wemoto, someone suggested on a forum and definitely not magnatec!

@finnerz89
I can’t be fully confident, but are brand new clutch plates.
Could it be a bedding in issue?

[Calum]

@spanners Did you soak the clutch plates in oil 24 hours prior to installing?

[declan]

@spanners are you sure your pv is set up mine was like a rev limiter on and off power around 6.5k

[Spanners]

@calum
We cover the clutch plates in the gearbox oil before installing them.
It was in accordance with the Haynes manual.
Should they have been soaked 24 hours?
If so, what are the implications of not doing this?
Have they not been soaking in the gearbox oil since installation?
How do l stop the clutch slipping from now or when it wears will it natural gather more grip when the high spots wear?
If not I’ve got a dangerous reving rocket! Ho-ho!

[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
