I bought one of these but it actually has 12mm and 14mm ends and not 12mm and 13mm as it says in the heading As an alternative would it be possible to fit a 12m or 14mm nut in place of the origin...

It's THAT time of year again for my TTR.

Every year, in the UK, a vehicle has to be licenced (road fund) and if over 2 years 11 months and 30 days old it will need an MoT certificate. Together with insurance it all adds up! In order that my bike stands a reasonable chance of securing an MoT certi...

I have a 2003 TTR 250 which seems to have an oil leak either from the "o" ring on the starter motor or somewhere close by. There also seems to have oil seeping out the grommet with 4 wires coming out of it, just in front of the front chain sprocket. Thank you Terry.
