Hello all, well to start off my bike is a 94 cbr 600 f2 and ran before putting in the new head gasket. I had rad fluid leaking into the exhaust so I changed the gasket. Bike ran before and now after i can get her to idle with choke but can not rev up. I have checked the timing and cam shaft position and they are fine. Any input would be awesome on what anyone thinks could be my problem.

 

what happens when you rev up and why did you remove the head ?.

This could be carbs so take them off to strip and clean.
check you cam chain tensioner but if this is faulty or incorrectly set the bike should either rattle or not turn over.
did you check the valve clearances when you had the valve cover off ?
did you have the head leveled when you removed ?

I would do a compression test to start, remove the spark plugs and turn the bike over with the kill switch in the off position to get a compression reading of each cylinder.

I am a complete amateur so wait for the other more experienced guys to give their thoughts as well.

welcome BTW

 

ok, i decided to do a full vacuum check and found that the cylinder #1 vacuum hose was not connected to the petcock, after connecting it she took a bit to fire up but now there is no problem. was my own fault for not seeing that hose disconnected. but thanks for the reply tho

 

ha, the one thing i didn't say start at the beginning hey.
glad its running

 

Glad you got it figured out. Ha always the simple things we overlook. I've been there plenty times.

 

I had the killswitch off after a shake down run, started shouting at the sky i was so angry it wouldnt start :-)
