I thought i would post this pic,its a ST4 my mate has just bought tax and tested...luckly he was stripping the bike,this is wot he found removing the belt cover,just shows you never no wots inside,its always worth checking your belts occasionally.
That's up there with the worst I've seen.... Just a note though. The tensioners have been done up wrong. They've been rotated clockwise to tension but should be done anti clockwise. That is the most probable cause of the carnage he has found in there.
yes anal canal i think,the bike was shitty under the fairing....i would imagine the seller had just had the belts done.
