during my practice session today it became apparent that i had to give it more and more gas just to pop it up. now it wont clutch up in second anymore or even do a power wheelie in first with -1/+7. i did notice that my spark plug cap on the right side of the bike (sitting on it) is rather wobbly and very easy to pull off. does the loose plug boot sound like it could cause that much power loss? other than it missing a bunch of ponies it still runs as it did before, smooth and screaming with a little popping under high rpm engine braking or deceleration

 

Yea if one of ur pistons isn't firing ur gonna lose alot of power Atleast noticeable power. Change ur plugs and check ur coils. Make sure everything snaps back tight. I had a 91 600 f2 I loved it.
