I just got an 03 CBR600rr ran great till a couple a weeks ago.. after i start it and ride up the street sometimes it just dies. Now i have an even bigger problem, it goes into gear, sounds fine... revs up but dont go like it should, i mean i can barely break 30mph. I havn't rode it much now that this has happened, in fear of creating an even bigger problem. The fan works and everything sounds good but i dont know what to do!! help please
Thanks

 

Sounds like a clutch problem to me.

 

Thats what I was thinking.

 

i hope not, i changed oil and filter.. then siphoned the gas outa the tank. I filled it up with reg fuel not premium 93 octane, bein a newb and not knowin it would make that much of a difference, so im hoping that will do it.

 

umm...so this started right after an oil change??? What kind of oil did you use?? I highly doubt putting in 87 or 89 octane is going to dog your bike like your saying it is. The wrong oil however could be the culprit.

 

well i believe i did put the wrong oil in it... my step dad step mom dad mom brothers... everyone has bikes and they made fun of me and said i wasted my money... so i changed the oil again with honda 10w-40 oil the recomended stuff, and put the right gas in it. Im happy to say its startin to run like it should. thanks for the help though

good to hear it was easy as that.

 

You put energy saving oil in it.
