Maybe a clog in the fuel joint that connects 1&2 to 3&4. Is there any gas in the 1 or 2 float bowls? Could be many things. Unfortunately..... keep at it. I really don't know much about the carbs. I've never had mine out except to install jet kit a long time ago.

are the pilot jets clogged in the bowls? What are the mixture screws set at? It looks like a long time of improper storage that caused that. As far as your fuel issue, the easiest way to tell if theyre not getting fire (if the bike runs) is when its running, just put the back of your hand close to each header pipe of the exhaust, if the perticular cylinder is firing, you will feel ALOT of heat off the pipe as in you wouldnt be able to touch them or youd scorch your hand. I had 2 cylinders not firing once and the pipes got slightly warm, just adjusted the mixture a bit and it sorted it self out.

those are your valves, and i can pretty much guarentee you that if the bike runs at all they all move. that wouldnt be your problem, you still havent specified if this bike runs or not.

yes it does run but when its cold it is really hard to get running i try to start it . it wont start

i try to pop start it it wont start

i wait , try again still wont start

i wait try again it wont start

wait try , wait try wait try ., hours pass

i wait try again it starts and acts like its not getting gas, ive cleand the carbs and they were dirty but still dosent seem to help start when cold .

i think the carbs are toast . the guy who had it befor me killed them when he try to clean them . i looked for used ones on the net and they look like they would do the same thing and i cant afford to buy more stuff tht dosent work . i looked at new carbs @ honda and there was 2 kinds . 1 was 900$ and the other was 1,400$

once it warm it starts no problem

thank u all for the input and suggestions u all have been a great help and i really appreciate it. wouldnt of made it this far with out all the help . thank u again guys

Are you using the choke when cold? Is the idle circuit clogged? I doubt the carbs are "toast", most anything can be fixed with the right knowledge. Keep at it and keep us updated.
