YPVS tips

@calum it's a brand new cylinder! Surely it's going to need some sort of lube to last as long as possible and minimize wear?
-
@irongamer727 No?
I mean, you use components that wear together. Brand new cylinder, brand new Powervalve bushes. Both will wear together.
But the idea is that the bushes have O-Rings on them, so there should be very little metal on metal contact. It's not a highload component. Therefore, wear is minimal.
You could put some white lithium grease on the components upon assembly, but it WILL burn off and eventually become a dry item.
As said, they get caked in carbon and two stroke so it's a moot point anyway
-
@calum will normal grease do? Such grease you use on the wheel axles for example?
-
@irongamer727 Yeah, as said, I really wouldn't go mad on it, cause it's going to burn off any how. Two stroke will probably be the best option here.
-
@irongamer727 I used 2 stroke on mine so do as I did as I think the grease is highly not needed and I personally would not trust the grease as I’ve heated grease up general purpose ad it gets quite waxy and may even combust
-
Didnt bother lubing my PV after rebuilding, ensured all surfaces were very clean and mirror polished, it doesnt do a full rotation and moves as much as say a rev counter or speedometer, the bushes would well outlast a piston un lubed, the thing you should really worry about it carbon sticking to the powervalve, so keep it clean and if you can be arsed mirror polish it.
-
@glynn123 when cleaning the pv. Should you always buy new o rings or can they normally be reused? How many km until you should inspect and clean?
-
@irongamer727 Pretty sure it comes with the Athena gasket kit.
I can't say I have ever gone out my way to replace the o ring or clean the valve.
-
@irongamer727 when Im cleaned mine , I had new seal and old seal in hand and couldnt tell the difference.
-
The Haynes manual says you need to make sure the pv is mounted correctly and not 180° wrong. Is it possible to mount it wrong? I mean it only fits one way?
-
@irongamer727 I guess it’s in the manual for a reason but I don’t actually know
-
@irongamer727 It means ensuring it's not upside down....I'd imagine.
-
Yup, it seems you can fit it upside down, thus restricking the bike.
Im pretty sure some bikes where sold in a restricted version like this. -
Can you twist and turn the servo motor for the pv without risking causing damage to it? I need to do so since the current setting is not optimal.
-
@irongamer727 Your servo is fubar anyway right? So can't see what harm it would do.
-
Nope have a new one
-
-
my question is wheather or not you could "rotate" the servo manually in order to adjust the pv better. The 2nd pulley is obviously a bit too far out.
