Air filters, LeMans 1

Stock 36mm pumpers.

I love velocity stacks, but know better. What's the collective wisdom on which air filter to use? Any that allow some kind of stack inside the filter?

TIA

Fred,

She sounds nice. I'd get a couple of these: http://www.knfilters.com/search/product ... rod=R-0642 I've used them on a T-3 and they work well. I'm not sure if you can fit a "stack" inside unless you can find a straight pipe section that will screw to the carb body. Perhaps you can acquire some PVC pipe of the correct diameter to thread onto the carb and take it from there. It may require using some type of union/adapter to have small enough pipe to fit into the air filter.

K&N's are difficult to fit over velocity stacks, they normally touch the frame on the LH side. You loose a fair amount of torque at lower to medium revs when you replace the stacks with filters (because you effectively shorten the inlet tract) even when properly re-jetted.

Try the original stacks with these:

Problem is Fred you can't have looks/performance AND good filtering :lol: .

If you plan to ride mainly where it isn't dusty K&N's are OK, they aren't that good at filtering out anything other than small birds and infants but they look sort of OK and don't upset the performance of the old tank too much. Better filtration will be provided by oiled foam filters but they are shit-ugly and will hinder performance and they clog fast but they do filter pretty well so if you're planning on riding across the Kalahari on it they'd be good. FAiling that you can tape a couple of layers of yer missus panty-hose over the bellmouths. That'll fix it!
