Didn't realise till I got the exhaust off but it seems to be suffering from a case of over ventilation
I thought it always sunny in the States, they must have rain like us
funny you should say mouse pee cos as the all 3 exhaust down pipes had been off for while by the look of it while it was layed up in the states so when took the pipes off you could make a dozen loaves of bread with grain the grain that came out. NOT THAT YOU WOULD WANT TO!!!!!
I ve read articles where people have said they used to drill small holes in the bottom of the exhausts to improve breathing for the exhausts when racing the bikes but that holes a tad large.
I love the smell of two stroke in the morning; its the smell of victory.
