Just about out ideas...
I've had my gas gas for about 5 months and haven't been able to ride it properly yet...
The big end went bang in May, and I've replaced this, new piston, new crank and bearing set, rebuilt it and it runs like a dog. So I've taken carbs off and cleaned them, same problem. Replaced the supressor cap and plug, same. So now I'm looking at the stator for timing, I've read every post on here about it, but I can't see how I can change the timing? I think is a 2k-3 by all the descriptions? The bike starts fine, revs out fine, and sounds brilliant, until I put it in gear, it dips a little, which clears with a little reving, but then riding away it dives on revs, almost stalling, then splutters like its starving for fuel, which it isn't. As the carb is full. I think it might be firing a little too late? Help...

To be honest, I'm not sure of the size, I have only cleaned them out, it did run before it went bang...
Just looking more at the stator, is it me or can they burn out? It looks very black and possibly burned out? Having just put it back together, I now have no spark at all...

that i don't know, what i would do is look at a wiring diagram and see what wire coming out of the stator does what, with a side light bulb and some wire test to see is there is a spark, then check all the loom clean and has no brakes and WD the connectors. clean the earth on the coil and WD the bolts and connectors.
work your way up the loom testing it at the connectors for a spark, if you have another 2 stroke or a mate who has one try and swap the coil if it fits. it does sound like feul but you saying the spark has gone changes it, i had my reeds brake away and it ran like a twat. with out being able to see the bike its hard to say what it is, worst case i think there is a stator on ebay. buy it if its not that sell it on. best of luck mate grant |

Since your this deep into it.. test the excitor coil of the stator. The sinle black covered post. This has the connector that goes up to your ignition/cdi. The spec should be the same as the KTM, below 14 ohm resistance between the two wires going to the cdi/ign bad. if you have a good hairdryer and the specs are lower of close to the 14, 14.4-15.5 good, heat the excitor coil up with a hairdryer and retest. Does sound like reed or powervavle not connected correctly after reassemble tho. Good luck!

Found the problem with the stator... A severed wire behind the plate!!!
One step closer, souldered it up, I have a big fat juicy spark... Now, all the dicking about with the jets and carbs, needs reverting, as it's drowning at the moment lol

Hmm, one of them is quite crispy Chris, didn't notice a smell though. When I do get this thing running, there won't be one thing I haven't dismantled and rebuilt on tho bike. I've had a huge learning experience... But I'd quite like a riding experience some time soon!
