Can't wait to ride it...
Happy and healthy new year folks! This place is a treasure.
Thank you for the kind words.
Helping GasGas riders in this way was what we were going for when we started this forum as "Talking Smack" on my (now closed) shop Smackover Motor Sports's web site. Jeff (the webmaster) has been great in keeping it going here.

If you take off the right powervalve cover and watch it as you rev the engine, you can see if the powervalve is moving through its full rotation.

Good Riding to You!
Jim
