Cota 348 Airbox

Featured Replies

Hi..

just bought my first trials bike in over 20 years..

A 77 Cota 348 thats missing its airbox..

can anyone point me in the right direction to where

I may locate one..

Thanks

Pete..

I had problems here in Australia finding the airbox. Could not find one and ended up getting one of those foam pod ones and no problems in rain, dust, etc.

Hi,

Ive got 2 349´s one is missing the airbox and I´ve fitted a universal foam thing.

If you want to get one a chap in Germany has reproduction ones www.montesa.de (there a bit expensive for liking).

The airbox isnt a common part to fail. There seem to be a number of bikes being broken.

My advice if you have time is to set up a search for montesa parts on Ebay.

Even consider looking for bikes being broken on Ebay and asking the seller privatly if he has an airbox left over.

Airboxes do come up now and again and rarely are bid on unless in 'new' condition.

I would be interested though to hear if there are any pitfals to using a simple foam filter. The airbox is a pain when it comes to removing the carb for clenaing, removal of the exhaust system. It would be easier to not use one.

there is one on ebay today.
