Cylinder Head O Ring

ectomite · 08-18-2018, 03:00 PM

If anyone could tell me where I could get this rubber o ring I would appreciate it and if I could get it locally would be cool. Megadan if ur looking at this I could use your help I know you have recently done this job also Thanks guys.

Just go to the hardware store or auto parts and match it up.

ectomite · 08-18-2018, 04:50 PM

Well I went to orielys the original o ring is flat all they have is round not sure if that matters.

Round or square section dosn't matter...
as long as it is 1/3 of the o-ring section above
the resess that it fits into it will be ok...
that stud is the oil passage for the head...
so make sure the O-ring you use is fuel/oil safe...

ie... if the head resess is 2mm deep you should use a 3mm
section O-ring...

Oh, wow thanks I have no idea if its oil safe oriely didn't know if it was heat or oil resistant. evidently the one they put in at the factory is neither because the bike only had 1000miles before it started leaking and that o ring was in prices crumbling a lot of guys have this same leak I'm thinking this is something rps needs to look at.

Omg, guys not going to believe this but I got that cylinder head back on and everything so all I got is the exaust left and I look and the gasket below that one is leaking also. It was not leaking before at all I'm wore out and did all that for nothing really. cause I got 2 rip it all back apart if I want that fixed and im not sure if I'm doing it. This has been a nightmare. bike problems after problems its ridiculous everything is horrible quality on this thing. Cannot believe all these gaskets leaking.

pete · 08-18-2018, 11:14 PM

don't give up...
pull it apart again... it will be worth it
once you have it sorted....

Thanks I'm calm now lol, ur right I shouldn't quit after some research I found that since the top cylinder head bolts also hold the bottom piece on witch has the bottom gasket that is leaking now. When you take them bolts out it ruins your bottom gasket seal in the process so its recommended to change both out. Good lesson for all of us. So I don't have any piston ring compressors so I'm just going to see if it leaks when I start it up since really it should be tourqed down. Does anyone know what these bolts torque should be? can't find the specs pic included.

ectomite,

I'm feeling where your coming from. I'm stalling out on a speedo install and nothing is working out. just gotta learn to step away for a while, regroup and tackle it with a clear head later.

Right now I'm too mad to look at my bike so I thought I'd come on here and see whats going on, now I have come up with two more strategies for tomorrow.

I was told you should replace all your gaskets with fresh ones everytime you dig into her....well... not if you go back in right away. I had to change my side head gasket two times this week. Bad oil cooler cover tearing up gasket

ectomite · 08-19-2018, 12:57 AM

Thanks craven good advice I'm going 2 cool down the rest of the way 2nite and mess with it 2Moro. Coincidentally I need 2 do the Speedo upgrade and it looks a little hard with all that's available rite now but ill deal with it when I get 2 it. Sorry your having trouble also I hope you get everything sorted.

Megadan · 08-19-2018, 04:01 PM

You don't always have to relace the base gasket when you pull the cylinder head. If you are careful to not disturb the cylinder and unseat the gasket then all is well and it shouldnt leak.

ectomite · 08-20-2018, 03:25 AM

Hey, megadan ya I don't know wat happened but oil leaked out but I got great news after driving it around for 3hrs its not leaking I must have lucked out. I just hope the little o ring does not fail like the last cause only choice I had was oriely auto parts.

pete · 08-20-2018, 04:14 AM

Buy yourself a O-ring kit....
everyone that works on motors should have one...

ectomite · 08-22-2018, 02:26 AM

Thanks Pete I did look at them I think I will definitely invest in a set. I'm just thankful I'm not ripping that engine apart again not very fun.
