AIR FILTER BOX RUBBER and CARB Fitting (ec200 2011 sixd)

[eliasn101]

When I removed the expansion ch. I saw that the fitting of the carb was very poor. I tried to correct it by removing the air filter and loosing the clamps both front and back of the carb. I could not fit it!!!! It seems that the air filter box is not long enough and anyway not "quite right".
The part number on the rubber box was "BE2501280017". In the gasgas parts list I have the p.n. is somewhat different. "BE250128017/2"
Are you aware of a change in the part in order to address this issue?

Its well documented. The best result I have found is to remove the air filter completely, loosen the top swingarm bolts, and remove the lower swing arm bolts. Remove the silencer/expansion chamber (or both). Then swing the whole subframe up. Remove the airboot from the airbox. It'll come out like a large gromet. Drop this part into a bucket of warm/hot water for a little while until it slightly softens. Then quickly install back into place and fit on the carb.

The other option is to just use a bit of heat from a hair dryer or heat gun to soften up the part you need and stretch it over some more.

So I'm not the only one with this issue!!!
The solution with the air gun is what I thought too. I will go that way but I'll try to find out if the difference in part numbering means something.
Thanks again jakobi!!!!!

I had the same problem with my 2011. I went the more extreme route and replaced the stock carb with the lectron carb which is about 7mm longer. I'm sure the heat gun will do the trick also.

My 2011 EC250R seems to fit fine.

Has yours got the plastic spacer on the carb Rick?

Mine never did and was a much better fit than the photo above.

I have the insert.

Perhaps I will change my tune when I have to remove and reinstall it.

After using the thermal gun in place. I removed nothing (to much work to bother) but I used the gun with great care since the plastic is rather soft and near alot of other things

I thing the result is OK.

thermal gun 12eu VS new spare part 16eu
learn to work on your bike and not letting the "specialists" robe you: PRICELESS
Also, accepting help from people that have the same interest with you 5000km away: Also PRICELESS!!!

What is the reason for the carb to air boot adapter? Is it a 36mm to 38mm carb thing? On my transformation I used the 11' air box boot (later part #) and it fits directly on the carb with no adapter.

 

[AZRickD]

I'd like to know as well. I saw it when I first rotated the carb to re-jet and wondered what problem this addition was supposed to fix?

Your photo makes me wonder if the AS I (round cap) is shorter than the AS II.

Info on the boot part #'s

The air box boot # BE250128017 is the boot GG has used for years (2001-2009). It has the bolt holes around the outside for mounting to the air box (01-06 used the holes). Boot #BE250128017/2 is the superseded part #. It does not have the holes drilled around the outer rim. This is used on the 2010-2013 bikes. I ordered the BE250128017 boot but was shipped the BE250128017/2. I doubt they service the older # anymore. If being mounted to an older bike you would just have to drill the holes for the mounting ring.

I think that the plastic black back-end of the carb is needed in order for the boot to "reach" the carb. The boot end is not that long.
Also, by using the adapter, they can use the same boot no matter the carb used.

So nknudsen gave us the solution to the big mistery of the part#.
Thanks.

All I can says is it's an improvement over the 2001 200 carb air boots
