Since you asked, here's my 20 year new baby/Bansheep killer.

1985 ATC 250R, ESR 310 kit w/TRX 9 Porting, 38mm Keihin Air Stryker, Boysen Rad Valve w/Pro Series Reeds, K & N Filter w/ Outerwears (no air box), Hinson Clutch Basket, FMF Pipe, DG Type II Silencer, Misc. Billet Parts; ESR Head & Exhaust Flange, Nac's Parking Brake Block-Off Plate & Kick Starter, Pro Design Shifter & Case Saver, Handmade Rear Brake Pedal (2-of-a-kind, thanks Red Rider), Renthal 400EX Bend Bars. Dry Weight: 277 lbs.

K & N Filter w/ Outerwears (no air box)

Did you use one of those airbox eliminator kits or did you just rig it up yourself? Got a pic of it?

I'm gonna do it myself real soon. I run with no lid anyway so it's pointless to have the airbox on there.

[Blown 331]

I would keep the air box and just run with out the lid. I think it gets plenty of air with no lid and the box keeps the filter much cleaner than no box at all.

[Mr. Sandman]

Sorry, no pics, but the filter mounts to the original air box mount and the box mounts to the frame the same. I just cut away all the surrounding plastic. I ran no lid for years but when I rebuilt the bike from the ground up, one of the things I was trying to acheive was to lighten the bike up as much as possible and even though the plastic doesn't weigh much, every ounce counts and that's how I got it down to 277 lbs, versus the 291 lbs. stock. Since I only ride dunes, I wasn't concerned about the filter getting too dirty.

[BigGreenMachine]

What else did you remove or replace with lighter parts to achieve 277 pounds? Very nice looking R by the way.

I don't ride in wet conditions so it's really pretty useless. The only thing I have to worry about is dust.

[Kintore]

really, I always thought it was bad to run with no lid... will it reck it the R? does it give you more power?

If you run with no lid make sure you clean your airfilter alot. Make sure its always sticky. Then you shouldnt have a probmel. It will only have problems if you dont put in the extra maintince it will need.

It'll give you a little more power if you're jetted properly for it. Won't hurt anything as far as being exposed as long as you have a good filter and keep it clean and oiled (I always use K&N filters). An outerwear sleeve is a good idea too.

[Kintore]

thanks for the info....ill try it with my R but I dont know if I will keep a lid on or not. I do mud running and everything so ill have to see.

[Mr. Sandman]

Thanks BGM. Basically everything that I replaced with the billet aluminum parts is where I saved the weight, plus the ITP wheels and lighter tires helped too. Losing the stock pipe and silencer shaved at least 10 lbs. right there.

Removing the air box lid and running a better breathing filter such as the
K & N will give you a slight power gain, but if you ride in mud and water it's best to leave it on.

[RideRed250R]

hey? wat does a k/n filter in a 85 stock air-box look like?
adam
i just got mine and it sits sideways in the box and iam confused it doesnt look like a k/n it looks foamy?

[Dammit!]

Here you go.

[Kintore]

does k+n make a filter for 84 R's?

[Mr. Sandman]

does k+n make a filter for 84 R's?

I'm sure they did, but can you still get one is the question. It's possible the 85/86 filter might work if they have the same air box as the 83/84. Anyone know?

[BigGreenMachine]

By any chance did you see the article on losing weight on a 250R. I belive they shave about 40 pounds which gave the bike a better power to weight ratio and also helps the suspension and handling characteristics. They used light wheels and alot of replacement aluminum parts as well as a +1 Cal-Fab (aluminum) and an aluminum sub-frame that was available.

[toyota200x]

Here you go.

Is the filter in a 250r mounted sideways like that. On my SX it is not like that? Just wondering
Thanks

[Dammit!]

Well that IS a 1986 250R so... yes. :D

[RideRed250R]

so is my 85
and a 84 is mounted straight off the back of the carb so no... but they do make a 84 R air-filter
