Are the seals on the intake boots OK? (the bit between the carb & the head) make sure there is no leak there first, they have a rubber o-ring.

yes they are fine.i have put fuel down the inlet on the carb boots and the bike tries to start but it seems to be firing back through the carbs cant figure it out got the manual and been through it several times setting the carbs still the same though.could it be a timing problem. help?

You had a plausible idea...

yes you should put gas in the engine.. but not through the inlets... Remove the sparkplug and put some through it, refit sparkplug, and fire her up!

I think your problem is the fuel pipe from the fuel tank to the carburetor is cracked or similar and is letting air inside thus not creating enough vaccum to suck in all the needed fuel!

also, try increasing the idle screw!
and for god sake, use the choke!

Give us a bit more info, was it running fine & then,,,,,?

Is this bike new to you? or some other knob cocked things up?
