Have a look at the camchain, guide & tensioner.

Carefully!!! Take the end nozzle off, thread the gun into the caliper carefully. It's a different thread, but it'll go in far enough for what you want to do.

Give it a go!

If you can't get them out, squirt a bit of something like Waxoyl in the hole before fitting a new nut. Hopefully, it'll clag all the loose bits together at the frames low point.

Well, don't be shy. What worked for you?

Impressive times!

PM'd.

Have a look in The Vault.

Turned out nice!

Nice one @Joseph!

Gonna wheelie like a bastard with that wheelbase, Ricardo!

Yes. The 850 top end will fit fine! But, as 1460 says, it could be badly seating valves, among other things.Make airline connection up for the plug hole, bring to tdc, and stick some psi into it. Inlet & exhaust valves leaking ... self explanatory. Hissing in the oil filler ... rings. Air outa the head/barrel interface ... head gasket.

Like it!

If you can't find an edge ... ?

Check 'The Vault' out.
