Hello Khalil,

This bike is indeed a little bit tricky, when it comes to camshaft timing.

First, you have to remove the small cover at the right-hand end of the crankshaft (three #3 Philips screws). Next to it there is a plug, remove this too (flat-headed screwdriver).
See Picture one.

In order to be able to turn the crankshaft, you will need a M8X40 allen head screw, and a M10 17mm-Hexagon nut. Pass the M8 screw through the M10 nut, and bolt it tightly to the crankshaft end. You will see another, smaller hole, where you have to insert a small screw or pin, to stop the M10 nut from turning. If everything goes well, turning the nut will turn the crankshaft.

Through the hole of the plug, find the "T" mark and align it with the arrow on the crankcase.
The marks on the camshafts are center-punch like, and they are next to the sprockets.
Align these marks with the marks on the camshaft holders. See picture two.
Put everything together, including the cam-chain tensioner, turn the crankshaft two full turns
and recheck timing.

If I can be of any more help, don't hesitate to get back to me...
Good luck.

Best Regards,

Motorcycle Repair
