Look at the needle to smooth delivery out. Try up and down a clip, or then alternative. Usually a bigger base diameter.
Don't you look at my accountant.
He's the only one I've got.
I put an FMF Gnarly pipe on it so I don't wreck the original and it saves a load of weight. The downside is a bit less bottom end but a lot more mid range and top end. Or their would be if I looked at the needle, it fluffs at high revs.
I only notice it fluffing at Vinduros, belting across big paddocks and open tracks trying to out drag KTM's in the trail class, otherwise I'm riding in gnadgery.
Putting the original pipe back on would bring the tractor back.
Next time I'm out I should set aside some time to play with the needle and see what happens. Apart from losing screws in the grass..
Thanks for the reply.
Come to think of it, I've never even checked the plug since I changed the pipe...
Lazy git.
Manopausal.
Think only of throttle position on 2 stroke carbs. Not revs.
Write that down on garage wall.
Drop a size or two on main should fix fluffing. If it was bitching it would be lean. And you would go up.
Clean Pilot jet out, replace plug before you do anything.
Consult garage wall.
Try screwing idle mixture in and out to see what happens in the off closed to slightly open position.
If you go too far in or out change Pilot that direction. In is richer..
Experiment with needle one position and see what happens. Clip up drops the needle which means it is leaner sooner. That can't change the base diameter.
Consult garage wall.
The jetting will help the pipe live its best life.

Haven't squeezed in enough bragging.
Ohh eee got 'lectric leg!

Clean out your fuel tap and filter and stop riding a two stroke at constant throttle
if you mean its wooly or rich ie spluttering but you could also drop your needle lower or use a fatter esp in the lower profile.
if its a mikuni (which i guess it is)you can try a new needle jet as the one you have will be worn oval by now.
if its a PWK keihin these aren't generally replaceable you have to use a fatter needle to compensate.
ps stop stealing out mud. It absolutely pissed down on Friday night here.

Kinky is using a feather. Perverted is using the whole chicken
I probably have the right needle downstairs we were going to try on my mates Race. I bought it for the XTrainer as it is one people recommend, but once I changed to the Fatty the surging (at about 1/3 throttle, I briefly had it legal) disappeared and it is just wonderful everywhere. Still might try it just to see.
Anyhoo I'll look up the number. I also got a NEDJ at the same time as it works well in other 300s (RM250 option).

So what needle and jetting are you running in your Xtrainer? I have removed the airbox lid on mine-36 pilot, 160 main needle dropped on clip IIRC. A wee bit fat in the lower midrange esp on a constant throttle opening. Symptoms more noticeable when it is warmer. Air bleed has been opened out.
With std setup it surged as described and was pretty gutless compared to my GG300.
I fitted a Fatty pipe and bought a couple of needles to experiment.
And rode it. Wow. Two mates said wow, one went out to replace his GG the next day with a Race (he's taller). The other still raves about it.
More powerful everywhere to my GG which went well. Strangely it seems to go a little better down low than the Race, but we haven't played with its jetting. Same engine but 38mm carb vs 36. And factory pipe. Vs FMF Fatty.
Carb remains unopened. Might have tweaked the mix screw. Pipe just seems to suit it. It is more vulnerable, but. . .

Better everywhere compared to std pipe. Thought Gnarly would be the way to go but they only list Fatty. No regrets.
