Hi, I have a cbf125 2009 9k miles, it has always ran sweet as a nut besides the sart up. Ever since I bought it, it
never run for over 1 minute after its started it would just loose revs and then eventually die. But once its hot it
would never die and ran fine. So after searching for a few answers I found that the problem could be the tappets being
way to tight and not alowing cold air to come through? Anyway after much research I set out to adjuest the tappets.
The first time I did it it wasn't right but I found that out before I started the engine. The second time im fairly sure I
I have adjusted them pretty damn correctly. However now when I start the engine the is a small tapping noise (loose
tappet?) and an irregular 3 beat tap. Its hard to expain but basically the tappets are rattling I thing. The rattling
noise only ever happened after I atempted to adjust them. On the plus side the engine now doesn't cut out which is
what I set out to achieve so I guess something good came out of it. Im going to try and fix it with any suggestions
tomorrow and if not reluctantly take it to my local dealership to get it sorted. Thanks
