Annoying Air Box

Featured Replies

Picked up a cheap 2001, 290 as a project. (what was i thinking ?) Stripped it down totally and ordered new parts as required. Postman Pat has applied for planning permission near my front door !

It's not too bad at all, dont think its had a hard life more an uncared for one.

Anyway, biggest problem that i have is the air box boss that connects to the carb rubber has broken away from the main air box body. Cant afford a new one and cant find a used one. Help !

Has anyone run one without the air box by using another system ?

If you still have the piece that has broke away, would it be possible for you to melt it back on with a soldering iron? :thumbup:

Thats a good idea. Think the angle may be critical though. Thanks.

yeah, the angle would be preety hard to get. it's hard enough to get the rubber hose over it when the airbox is fine!

Thought about a longer rubber pipe from the carb into the box then seal it. not really sure how to proceed.

You`ll have to spot plastic weld it together when fitted to the bike then remove it and complete the weld and re-fit. Angle problem solved.

Hi, after welding I'd think about reinforcing the welded joint in some way. Also think about doing the spot weld thing as mentioned and then taking it to a shop that does plastic welding, just an idea good luck.

Had my 01 airbox rewelded when I still owned it, a decent plastic welder will be able to make it much better than standard

Hi guys, thanks for all the help !

Fired up the soldering iron, with the air box in place, tacked the broken boss in a couple of places then waited for it to harden. Removed the air box carefully then proceeded to 'weld' all the way around. I 'pushed' the melting material from the outside of the air box and then repeated this by 'pushing material from the boss until the plastic met and melted in the centre. Took a couple of hours and it worked ! After cooling it left a very strong joint. The angle is not perfect but it works just fine, everything fits and tightens up well. Another forum victory thanks to you all. Cheers, D.
