Just bought a 98 CBR 600 f3 it was wrecked and the previous owner tried to change into a Street fFghter. When I got it home it would not start.... I have got it running and it will idle fine first gear is good but when shifting into second I lose all power and the bike bogs ... I have cleaned the carbs but know that it is a carb problem..... it can be the floats are not working correct or air-fuel ratio needs adjusting, any suggestions will be appreciated
Hey Mata,
You have purchased a project that may be complicated... Internal combustion engines need only three things to run..(if it was assembled correctly)
1. A properly timed spark
2. Compression
3. Proper fuel ratio
..NOW - First, You need to run a full compression check on all cylinders.. this will eliminate a compression issue that would prevent the engine from running right! Compression should be 120+psi MINiMUM with the throttle held wide open and the engine spun for 6-8 seconds.(on each cyl) ..If you have more than 20PSI difference between ANY two cylinders you have a problem.. and this MUST be repaired before proceeding - Next, take the carbs to a qualified professional and have him check, clean, and set the carbs... once you get them back, make sure you have fuel going to the carbs..If all is correct, and you have installed NEW spark plugs.. it should run..and run well..

wow, 7 years without use! try to check if the fuel pump motor is still working... also check the fuel lines if its clogged.. I hope you get your bike up and running again... feel that adrenaline rush when going 100+mph.. hehehe.. have a good one bro...
