My cbr400

[alecks69]

i think the cbr's droperd a cylinder. was riding it (it did need chronic carby tune/work) stoped for a quick break started it up and she was making a bad tack/tocking noise.

i think this is due to fowl plugs due to the untuned carby well heres hoping.

i rode it to the nearest garage and its siting there.
any ideas please ask questions i will strive to give you awnsers
