I have a 1986 Ninja 250 that I bought from a friend. Long story short this bike has been raced and abused. It was also highly modified for that purpose. I have been working on getting it back to stock. one of the problems that I am having is that It will not rev over 5000 RPM's or if it does it bogs really bad. Very slow to come up to speed. Not sure if I used the right jet needles in it or not. The ones that I am using come from a rebuild kit. The ones that came with it were the clip style but it does not want to start when using those.

Took it out for a quick spin the other day and a mile down the road it lost power and died. Not sure what to check and work on at this point.

In addition to it not revving up, there is a popping/ticking sound coming from the right upper side of the engine that only happens when gassing it up. At idle it is fine. any help with these problems would be greatly appreciated.

Thanks
Tom
