I got a deal on my 250r it had a holed piston from being lean. I found out the air filter was half off since the rubber tube was crushed in.

Does anyone know what size the inner diameter of the air box tube?, was thinking I could buy some pvc and cut a ring to put in there. I know they make em but I'll be damned to buy a $20 piece of something I can make myself.

 

Don't waste you time I tried to do the same thing. I believe the size is 4" OD. The problem is that the pvc for a pipe that big is very thick causing a huge restriction in the air flow. I know this because After installing to I was way rich in my jetting.

Look on e-bay some guy is selling them single for about $10, I too don't see the need for two of them at $20.

 

Thanks! I guess I will buy on of them..

 

not sure but i read this somewhere. a bottle off one of those hand held torches will work. same size. cut of course.

 

Thanks!
