Bike seems to leak coolant from kickstand ??

[mbmO8]

Standard barrel and derestricted but factory head and I torqued them to the best of my ability due to the tight space some of the bolts are in

[Calum]

Yeah it's a nightmare trying to get the torque wrench in, can help to drop the front engine mount bolt gives you a bit of wiggle room.

Just go over the bolts and make sure none of them have rattled loose again.

Often these things come from a very simple place. So just double/triple check all coolant hoses/unions etc.

I had a spare head gasket from the gasket set I got from yambits I know it’s not Athena but I’ll order one up and it’s on now and seaming to be fine thank you lot

[mbmO8]

And that didn’t last long …

The gasket has started leaking already after maybe 80 miles. Going to order an Athena one later tonight and I was wondering if it would be worth skimming my head and barrel mating surfaces?

[Calum]

Yeah, I've never had any luck with the pattern ones.

[mbmO8]

Is that not too uncommon for them to go that soon? As I’m starting to worry it could be something else causing them to fail so often

[Calum]

Only use Athena, Genuine or Vertex head gaskets. The white ones blow straight away.

It was a black/gray one from a top end kit from yambits but even when I installed it it didn’t leak coolent but didn’t hold compression

[Rallyfinnen]

I suspect the head or top of cylinder is not flat if you're having issues again and again. I would take cylinder and head to a machine shop or do it yourself if you have the equipment.

[mbmO8]

I think that will be the plan for now. I’ll get the barrel off and order new studs and I will check the reeds too

[SpookDog]

Have you lowered the coolant level in the expansion tank to the centre marking.

Also try measuring the head stud length that is protruding. Then again between the barrel top and washer with the dome nuts screwed down.

I’ve got the same problem with gaskets blowing. In my case it’s getting sucked into the chamber causing white - grey smoke.
Trouble is i don’t trust the local mom&pop engineer firms. The last job was a re honing shit show.
PJME skim heads?

PS Same issue, bottom of gasket is dry and the top has oily wet channels…
