I see a 2K3 and an older carb. Can tell by the deep bowl on it. I'd be interested to know if you got one of those flashy CDI units.
 
Very nice , out of interest did it come with a spares kit

In terms of spares/accessories, this is what was in the crate:

Plastic container with 1 needle, 1 pilot & 4 mains.
Extra XC graphics set, with rim graphics.
Tool kit with GasGas fanny pack.
Hand guards(not heavy enough for the type of riding I do.)

Bike is now insured and street plated.:D

Haven't pulled the tank off to verify, but from the side it looks like the one in Glenns pic in the other thread.

I'm not yet familiar enough with the Airstriker carbs to know which is which yet. This one appears to have a screw top though.

The ASII has a shallow bowl and a flat top. See attachment.

You can tell which flywheel you got by checking the position that the cables leave the case. At the 2pm position its a 2K3, and at 10am its 2K2. Also visble in the attachment.

Have they moved the CDI from out of the airbox now? Looks like you might have scored a 2K2 if you didn't get an e-start. I think thats swell that Glenns bike arrived just how he wanted it.

BJ got the estart bike, so it's a 2K3. I would have expected the AS II on an estart bike, with the AS I on race models. Obviously there was a shortage of AS II carbs OR the factory decided the older version was the better unit.

History tells us the AS I is easier to jet.
 
I doubt they selected the carbs using any logic and more so on availability. Same thing happened in 2011 with 36/38mm ASII. Different numbered slides (with/without the notch). Varying degrees of spacers and mounting setups. Some with philips head fasteners, others with allen heads. With all the variables no wonder we all ended up with different jetting specs, but not denying the ASII is sensitive to minor changes too.

It seems Gas Gas is a low priority to Keihin and as such either takes what its given or whats available after the other big buyers take their cut.

Jakobi, what is the difference between 2am and pm or 10 am and pm on a dial clock? are clocks in OZ different? My clock is in the same position at 2am as it is at 2pm. ;)

But surely 10 and 2 are different positions, regardless of am or pm.
 
Yeah but its different times jeffs so while it appears the hands are in the same position, how can they be?

Haha! Good pickup mate. I didn't even recognise I had done it, and in hindsight I have no idea why I went with one at am and the other at pm. It was clearly am in Aus when I was typing it. Mostly likely pre morning coffee.. 09:37am to be precise. Its a hard life I tells ya!

You're right Noobi.. It makes no difference to the thread but must admit its pretty piss funny that I'd type it.. I'm going to stick to 24hour time now!

LOL! I read his post and didn't even catch that. Funny!
Even if Jakobi has a different clock he is correct about the Kehin supply issue. I believe the old regime at Gas Gas owed Kehin some money that was eventually paid. Apparently Kehin hasn't forgiven that sin so now GG has to pre-pay months in advance and it is not unusual for Kehin to under deliver. This is one of the main reasons for the Ossa alliance, too.
 
I have a different take on this whole EFI/DI thing than some of you guys. When you start a race and the carb is working correctly, it continues to work correctly all through the race. EFI/DI can quit suddenly and there's not a damn thing you can do to fix it. Ask Mike Lafferty about the TX National last year when he was leading until the 4th section and his Husaberg stopped running. I just don't think EFI/DI is ready for our dirty and hot off road world yet.
I really like the Smart Carb thing because it allows external adjustment with the turn of a button but has no electronics to die. The API Smart Carb guys are going back to Spain next month to do some more testing with the factory.
I believe it has the best of both worlds. They claim lower emissions and better fuel economy due to better atomization of fuel where EFI squrts fuel into the engine.
 
I for 1 DO NOT want a fuel-injected dirt bike, not until there have been several thousand more of them sold to others who are willing to be beta testers to work out all the bugs.
 
IMO, as an engineer, the problems are largely thermal due to packaging. When my friend brought his EFI 390 Berg home I had a close look and told him to expect issues. My Cannondale, despite its many flaws, had a very reliable system once properly insulated. Cheap to fix with off the shelf parts (no $500 fuel pump). The reason the in tank pumps die in these bikes is they cavitate in the boiling gas from a tank right over a super hot header. A two stroke would not have this problem, or a four stroke with an external fuel module(pump/regulator/filter).

I like the simplicty of a carb, and agree on bypassing the EFI two stroke, but would trade it for the power and lack of a large pipe that DI would allow.

GMP, I'm no engineer so this part of your post intrigues me--DI would allow a different shape of pipe?
 
I'm no expert on this, but from what I have read yes. Maybe not a straight pipe but not a bulbous chamber either. Fuel is injected under high pressure after the exhaust port closes, and in one of the latest designs along with some air to increase atomization. No reverse shock wave needed (the purpose of an expansion chamber) to prevent mixture form blowing out of an open exhaust port. Some of the dyno results were incredible. I'll try and find the link.
