Yeah ok must check reeds then as can feel air coming back out through them.. Yeah bike was running 100% started first kick was just using Coolant and pressurising cooling system hence why I did the gaskets.. As for comp gauge it's brand new and reads ok on my car..

Cheers for the reply but that wouldn't explain the low compression I'm getting and the air coming back out through the reeds I'm thinking maybe bad rings?

I did the compression test with the carbs off altogether but beforehand when they were on yeah choke tube was on tight..

First post on this so apologies in advance for any mistakes.. Problem banshee was pressurising cooling system (blew pipe one day) and air bubbles in radiator so I assumed head gasket? Striped of head had it skimmed and repaced both top and lower gaskets and retorqued 22fp.. Tried to fire bike up wouldn't start finally got it started by putting bit fuel through air intake but no bike revs nearly full throttle as soon as I fire it up which I'm assuming is an air leak? I did a compression test and both cylinders coming up 70psi which I know is low but when I put my hand over reeds when doing comp test I can feel air coming out through them is this normal? Why would I have such low compression after replacing gaskets maybe rings? Any help would be appreciated thanks..
