have you read the "dyno`d today" thread.....might be worth a go 

I would have a go, when my bike is fixed. What's the point of going on dyno, when bike runs like ****?
I thought that dyno it's just for adjusting, tuning, not the fixing, right?

My money is on fuelling here.....as a couple have mentioned earlier - check your breather pipe. You say it only started recently and it kinda coincided with you blocking the drain pipe. Sure it's the drain pipe and not the breather?? Also, why did you need to block the drain pipe in the first place?Make sure both are unblocked and you can blow through them.

Breather pipe it's clear. Drain pipe is blocked, because of fuel leak (possibly corroded inside of the tank).

Of course that's the theory. The way I've determined which one it's the breather and which one it's the drain, was just assumption that breather pipe can't leak.
