Hi all 1st post here.

New to trials & have jumped in with a new 09 125 Gasser which is fab-only problem is that if it doesn't start 1st or 2nd kick when cold you can be turning it over for 10mins or so before it finally goes.Have checked plug which is always dry.

Once going it starts 1st kick all day long.

Any ideas?

Is it kehin or dellorto?

[sectiononecleaner]

dude, if your having problems on a new bike, ring your dealer or importer, surely they will sort for you.

Dellorto

Any help appreciated

hi we too have an 09 gasser and it starts well. The only thing is it is very different to sherco and betas we have had that the gasser needs a very 'sharp' kick. push down gently to find compression then kick down sharply. I have been told to be careful with the kickstart mechanisms as they don't like continuous kicking. Hope this helps

When i got my 125 sherco 08 new it done that and didnt tick over but we just had to adjust the revs and stuff and then it worked perfectly like sherco's do

Assuming all other things are good (connections tight, including the plug cap screwed on well, a good plug gapped to .024", .6mm, absolutely fresh premix etc) you might try a larger "starter jet", which is the jet on the brass tower that feeds the starter circuit. Some come with a #60 and they seem to work better with a #80 (or you can drill out the jet with a .031" drill). Be sure to NOT open the throttle when kicking it over as that defeats the starting enrichening device. When kicking it, be sure to engage the racheting mechanism easy before putting weight on the lever and the parts will last as long as you have the bike. It's the slamming down on the kickstart lever that breaks parts.

I'm guessing you are opening the throttle like a four-stroke carb when you kick it cold.

Jon, here in the uk we don't mess with jets too much, think the gassers are pretty much spot on for jetting.
factory kev and shirty will sort this problem if it is one, but my first trip would be to the dealer.

However, assuming you know how the choke works and you have new clean fresh petrol and have a good spark then first check float level then the banjo filter. If not it may be the choke.

Thanks, Nigel.
Here in the Midwest U.S. we ride in some pretty cold weather and the #80 jet seems to help cold starting. Riders on the East and West coasts also find the stock jetting works well, as you mentioned. Kev and Shirty are very sharp and should find the problem in a couple of minutes, I agree the first trip should be to the dealer on a new bike.

Cheers.

i was having a look at the choke mecahnism today, and whenever you pull the choke lever up nothing realy seems to hapen to the engine.when i pull the choke up the the brass rod beneath it doesnt move but if you pull it a little further the brass rod starts to move and i was wondering if you have to lift the choke lever untill it points to vertical because we have only been lifting it to about 10 degress?

The lever needs to be vertical to open the starting mechanism, 10 degrees will not usually start to open the bypass orifice which the starter jet feeds. If you drill a small hole in the end of the lever arm and attach a small ziptye, it will be easier to pull on the ziptye end as the upright lever is hard to find with gloves on.

so could this be the problem then? me not pulling the choke up fully.and that would explain why it starts easy once warm and not when its cold?

That's my guess. The 125s are easy to light off, just be sure to not open the throttle when kicking and expect it to idle a little higher with the "choke" on.

Cheers.
