Hi Mark,
Looking closer do have fitted a non standard rear chain guide? If yes what is it and how easy was it to fit? Do you have a closer picture of it?
Thanks and regards,
Dion.
Sorry but i seen this photo on TWITTER. now and again i type in Yamaha TTR250 on twitter and check out TTR adds or photos. There also an old FACEBOOK page that hasnt been used since 2012. Now and again people throw in photos on the "post to page section.
They would need to make there own with the size of that rear sprocket and the chain guide looks to be sitting on extender block aswell I have extenders on mine to clear the sprocket aswell.
