Pv adjustment help
-
@declan Cool, so with that being the case, if it's still not reving past 8K, you now at least now it's not the PV. To test that properly. Let the PV line with the port, then disconnect the servo. It should red line unless there is another underlying issue.

Hi All........
Remember when l first joined the forum and said there would be some stupid questions.
As you all know l have been making good my DT 125 and today l actually was able to take her for a spin.
Now l have no doubt that the PV is doing something but when it come in it feels like you are clutching it?
It is wild, at 6000rpm all hell breaks loose, but it just feels like it is not operating properly.
I hope l explain it properly, it’s not a rush of power more like your dipping the clutch to create more RPM’s?
Any ideas, is it too a set up issue?
Sounds stupid but how should it feel?

Sounds stupid but how should it feel?@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.

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.

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! -

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

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......

I'd follow the Haynes manual procedure for setting up the clutch, then worry about the power valve after.Current bikes:
DT125X '07
Street Triple R '11
Aprilia ETV1000 '02Previous:
DR650RSE '96
