Hi all
As stated in another topic I am likely to sell the X9 Evo 125.
To be fair to a new owner I will change the transmission belt.
Question.
Is it as simple as the info on this site and the Haynes manual state? It look as if it is not necessary to remove body panels or would it be better to remove them?
Note, I have worked on motor bikes and changed primary chains and manual clutches so it's just the 'catch' I might run into. Good tool selection available and engineering background before retiring.
Thanks in anticipation.
Regards

You will also need the tool for holding the variator when tightening the variator nut to the correct torque as its unwise to use the impact driver to do this. ( Although you might get away with it if you mark the position of the nut before you loosen it). You might be able to make this tool if you can't get access to one, but beware of damaging the outer pulley and fan blades. Another common issue is getting the belt trapped too low in the front pulley so that even when the nut is correctly torqued the assembly is not fully home. It then comes loose once you start to run and can wreck everything. A certain amount of brute force is needed on the back pulley halves to twist and pull them apart to get the belt down enough to give you some slack at the front. ( twisting is needed because the rear pulley moving half is on a worm drive). Once everything is back in place and looking right turn the engine by hand or run it briefly before double checking the variator nut.

Solo can do it blindfolded at the side of the road in the dark and when it's snowing...so you should be able to do it without any problems. A holding tool is better on a 125 as it helps support the shaft from bending forces as well as stopping it turning. The Buzetti ones are cheap enough on Ebay.
Note the belt may have direction markings, the 500 ones do.
