rm twinair box
« on: March 30, 2011, 08:59:04 pm »
I have just fitted up a twin air single sided airbox to my rm465 and just wondering what others have used for a filter to suit . I am thinking that an 84 rm250 filter would go close but I cant get to my 250 at the moment to check.

If you find one let us know. I couldnt find one for mine but i think i heard a YZ 80 filter fits ??? Or the only option is to DIY one out of some foam.

Do you know if anyone makes a new rubber boot? Mines perished.

I made mine up from sheet foam that uni filter sell,I think that the DR400 filter is a close match. If you get your boot remade,I need another :-[

Will check mine tomorrow. Not sure its even good enough to copy. Would be great if 4 robs was still going, infact i think he already used to do the rubbers. i think there are more than one type of rubbers too. I think this airbox came off a PE175 but i think its the same as 125 anyway. Not sure about 250/465/500.

Yeah, they fit all the 125,250,465/500. I think fernando at husky parts does the rubbers now  ;)

Craig,no I think that he would be able to replicate on if he had a sample. The one I have is really for a 125, so if some one has one for a 250/500 maybe they could send that one off. What about Scotts ???

Mine is not too bad, just a couple cracks i might be able to fix with Sicaflex.

I now know there was at least 2 rubber boots. This one and there was one with a square chamber in between the air box and carby.

Poly-Air also made these air boxes but i think they were all made by the same company and just re-branded by other compainies.
