baldilocks Posted June 3, 2017 Report Share Posted June 3, 2017 (edited) Every gas gas I have had takes 3 kicks to start hot or cold. Jetting normally ok but at sea level it may pink a little about 1/4 to 1/2 throttle. If it does then a number 3 slide will cure it but they are about £60. Most people just put up with it.

What will the number 3 slide do ? It is hard to start just thinking there is a technique or jetting or timing is out Edited June 4, 2017 by Markws80 Quote Link to comment Share on other sites More sharing options...
baldilocks Posted June 4, 2017 Report Share Posted June 4, 2017 Number 3 slide is richer ( more fuel / less air ) than a 3.5 which is the standard slide. Kicking may well be a technique issue, get the kickstart to the top of the stroke and kick it quite hard. All I'm saying is it was always three kicks so don't expect much better than that Quote Link to comment Share on other sites More sharing options...
baldilocks Posted June 4, 2017 Report Share Posted June 4, 2017 Yes call gas gas uk and ask to speak to factory kev. They'll put you on to someone else as factory kev left in April to go self employed..... Look up Kev Hipwell on Facebook. Quote Link to comment Share on other sites More sharing options...

GasGas pro is known to be not an easy starting bike....a lot of owners say the same Technique= Choke on..no throttle....fast kick. So do you want us all to stop replying to questions in future as in your view we don't know as much as a Gas Gas Mechanic ? It's an Internet forum, owners and riders share their experiences. Nobody's saying you have to take anyone's advice but it's a bit strong to imply the poster should disregard people who take the time to answer his question.

cragvale Posted June 4, 2017 Report Share Posted June 4, 2017 I went through the same pain with my sons bike, gas gas pro 125 I could start it ( not first kick ) he could not easily, excellent bike in superb condition, just hard to start, bit the bullet and bought Sherco 125 which starts first time. Whilst it is definitely a matter of technique, Gas Gas are clearly not the easiest bikes to start. Ironically the gas gas was previously owned and maintained by factory Kev, it was his Sons bike.

Markws80 Posted June 4, 2017 Author Report Share Posted June 4, 2017 (edited) Thanks I just wondered if anyone had a 2017 250 whose play with jetting and got a good setting I done a trial today and I think I've got the hang of starting it There seem to be a bit of pinking Edited June 4, 2017 by Markws80 Quote Link to comment Share on other sites More sharing options...
