1994 CBR F2. My problem is that I can ride the bike on short trips uneventfully but when I ride long enough the bike will die leaving me on the side of the road. The exhaust note changes followed by loss of power and then complete shut down. If I try to start the bike it will crank with no start. I give it about ten minutes and it will start with hesitation then I rev it through the rpm's and it takes off like it never happened. I run 93 octane if that has any significance? Any ideas?

 

My f2 used to do that too....it was a charging problem for me.

My battery wasn't being charged so it would die on long trips or in stop and go traffic.

New regulator/rectifier, stator and wiring harness....and new battery [&o]

 

It could be one of a few things. Check your fuel line off the petcock...make sure it is not pinched in any way. Then check for spark...just pick up a spark tester at autozone or any auto parts store. If you are getting spark and it will not start then you are not getting fuel. If you are getting spark and your fuel line is clear....try bleeding the carb bowls...then try to start the bike. If it starts you could have the bowl breather tubes blocked off some way. Hope this helps in some way.

 

Mine did the same thing! The problem with mine was the 2 vaccum lines from the tank that just hang. Make sure that its no pinched!
