Reply To: old GT250 valve clearance
it looks quite expensive to get a shim kit 7.48mm
It is, hey? I was suprised. You can get individual shims of 7.48mm. Write down the SHIM for each VALVE in your bike. The SIZE of the SHIM is written on the top. There’s an A, B, C & D stamped inside the head assembly so i write down Front A-170 B-175, etc. Then i bought shims that were slightly bigger & was going to put them in but it won’t be right. Getting feeler guages to measure the gaps & buy the exact shims required for each of the 8 valves.
I’m well & truely sorting a troubled 2008 GT250R out. It’s going to be very lively when the gaskets arrive & i put the head back on. If you want i can help you get that bike running well without it costing you much.
