If it has no compression at all, I would be taking the barrel off and checking the piston and rings. Either that or you have adjusted your valves incorrectly.

spark plug done up tight?

yeah its done up tight

have you checked the spark? pull the sparkplug out and put it in the sparklead.... hold the plug in you fist and kick the bike over...
If you don't get a shock from it you have an electrical problem

 

[Moto99]

nahh its got spark, thanks for the help

Go over you valves again make sure you didn't do them at valve overlap.

Was it blowing any smoke the last time it was running?

Also what did you adjust your valves too?

 

[sean01]

no compression can be from the factory decomp on the camshaft.. i have seen these play up alot.. take the front (large cover that holds the head and barrel on) rocker cover off and have a look, if your not sure then post a pic of it

just run over everything as said above, failing tht take motorman's advice

 

[Moto99]

Yeah will do tomorrow, but when i seem to kick it it sounds like theres air escaping from the barrel
if that helps?

 

[motophreak]

yeh same as mine....if you take of the cam cover it sounds like more air is escaping yer?? most probably the valves

 

[Moto99]

Yeah sounds like it, will have to check cheers!

 

[mattbombers]

well, check ya gaskets and also your valves

 

[Moto99]

Yeah ive brought brand new gaskets, so thats not a problem

so you have fuel / spark / air .... it should start... but no compression points to valve problems

have you tried winding up the idle a bit... and turn the fuel screw all the way in then back out 1.5 turns this will get our carby into a setting where it will start any engine if in working condition

when you cleaned the carby did you blast out the jets with an air compressor? andhave you made sure t float bowl is filling with fuel? also it will help to completely drain the fuel tank.... flush it out with fresh fuel.. then fill it up again

using a new sparkplug?

when you try to the start the bike does it fire at all? like does it sound like it wants to start or is it more like there's no fuel and your just kicking a dead engine?

 

[Moto99]

It sounds like it really wants to start but it aint starting, might have a bent valve of what not cheers
