exup bearing price shock

[solorider]

i did a bit of comparing the old and replacement parts and one thing i found was the exup valve seems to wear more than the collar,my old exup valve was very worn and there is a groove mark on the pulley end,it did need replacement and the exup valve is not a cheap item,there was a new one on ebay for £222 and that is a lot cheaper than one from a yamaha dealer
