Hey, im new to this site, quick question, I have a 1998 Honda CBR F3 that is giving me some trouble. Its got a hard time starting, i've cleaned the carbs, and gas lines, new battery, checked the timing, replaced plugs, checked all vacume lines for clogs, changed sparked plugs. If i finally do get it over and i take her out it only lasts 15 min before it dies on me. some times i can bum start it or boost it but it doesnt last. Any suggestions would be appreciated. Thanks.

 

Have you drained the gas tank and put new gas in it?

 

this is my 4th time trying... do a load test on the battery. Sounds li.k.e bike is dying because of there being low voltage in the electrical system. Also check your regulator/rectifier R/R . There is a thread on how to do this... I will put it up as soon as I find it.

 

is the choke choking?mine will not start cold without the choke.

 

I would check to make sure your fuel petcock is not plugged. Pull the line from your tank and open the petcock to see if fuel runs out. It should be a fairly good stream of fuel, not a trickle.

Also, next time it wont start, pull the plug on the bottom of carbs float bowls. (should just be a screw) and see how much fuel runs out. This should tell you if your getting gas to your carbs.

 

Here are the links I was talking about.
