620s racers...have you? Airboxes/crankcase breathers: Have any of you disconnected the crankcase breather from the expansion tank, thrown the tank away and then blocked the connection from the airbox to the expansion tank? Dumping warm oily air from a gearbox into an airbox is done for pollution and emission regs but, it's generally thought to be pretty bad practice as far as performance is concerned. Back in the mid-80's my CBX550 had such an arrangement. When I removed the gubbins it gave an instant performance increase amounting to about 5mph at the top end. It made it a bugger to warm up though (knew nothing about jetting in those days). Frames: I am breaking on of my 800's for spares. It happens to have a bent frame where the forks have quite clearly hit the frame tubes as the steering turned forcibly back in a crash. I understand that this is a common cause of writing the bike off. The frame is a bit soft. Anyway, on this particular example, although somehow the forks have contacted the frame tubes, the lockstops were not broken in anyway. It might be worth your while adjusting the stops to reduce the amount of steering lock you have to give that extra margin just in case. You also might want to consider putting some thick rubber pads on the frame to absorb any energy that might come from contact with the forks in a crash. |
