RE: knocking during acceleration
 
yeah i put in the octane boost and it didnt help. ive heard alot of stuff about seafoam, maybe ill try that aswell. the plugs i got are honda oem so they are already pre gapped 9's aswell, just have to wait for my wrench before i can rule them out as a problem.

the bike only has 14k miles on it, dont the ccts usually go out around 20k? the only thing stopping me from getting a new cct is the fact that i only have 50 bux left on my creditcard before i max, and i need gas too or none of this even matters, haha.

anyone happen to have a spare one laying around that i can pay shipping for, or maybe swap you a part? :)

i didnt see any metal flakes in my last oil change, so does that rule out worn piston and cylinder?
how would i go about making my mixture less lean?
the fuel qaulity is not it.
carbon build up, i bought some sea foam, thatll rule that out right?
ignition timing, ill open it up and make sure the timing is on the f mark.

and with the seafoam, is it ok if i mix it with octane booster?

i just filled up and put in the octane booster, so im curious if i need to drain the tank first then fill up and put in sea foam

ok, new fuel, but this time i used seafoam. i put about 4.5oz should seem resonable? let her idle for a bit then took her for a quick ride around downtown to feel for any changes and inspect the noise some more. the knocking didnt go away, but i noticed that it only knocks when the bike is pulling wieght, i read on a forum some where that if your chain is too tight itll do that. anyone else heard of this?

Is it possible something happened in your recent wreck? Did it bang the bike around a bit?

i high sided on my right, smashed the mirror and snapped off the brake lever, etc.

but i just went out and checked and my chain is tight, way too tight. so tomorrow it looks like im waking up rise and shine and heading to home depot to get a socket for the rear axle nut. any of you guys happen to know the mm of the socket?
