Hi all,
After spending eons surfing through web sites and even this forum, I have given up and finally decided to post my problem. There are actually 2; I am hoping they are not related. Its obviously not a new bike compared to what the others are riding in this forum, but I am hoping your expertise surpasses the age of your bikes.

Problem 1
I am having an intermittent starting problem with my CBR. It starts up fine some days regardless of the weather or whether its been on a long ride or just sitting in the garage for a few days. However, on some occasions, the bike will not start no matter what. The starter turns over, but the engine does not fire. If however, I push start the bike, it fires up pretty easily. The carbs are clean, the fuel pump is fine, the jets are clean. The battery is new and I did replace the rectifier a little while ago (close to 2 years ago maybe). The spark plugs are clean and have a nice brown colour to them. They do spark when grounded on the bike.
Now, I make it a point to park the bike somewhere near a gentle slope in case I need to go for plan B ! Its very frustrating and I am losing confidence in the oldie.

Problem 2
Now we come to the choke. Does not work and only ends up bogging the bike on all settings.

Any ideas, suggestions and comments would be more than welcome.

Maybe your fuel filter is clogging up, or the fuel pump also.

 

Thanks for your reply. Now, would that explain the success with jump start ? Also, if the filters/pump was faulty, normal riding would be hampered too.

 

Mine did the same thing. At the end of the carb assembly theres a little **** for lack of teck terms, that the choke pulls out, adjust the choke to be snug at this point. Also lubricate cable and adjust. If the carbs are bad, I like to take off tank, connect my dirt bike tank to the carbs, expose the intakes and use seafoam, man that stuff is great. Also adjust idle.
