I've searched but not found any information on modifying the stock zenoah air filter to allow more air into the engine. I think drilling holes on the outer side, where the cooler air would be, would help more cool air get into the filter, but you'd have to be careful to drill where the air would still be filtered. Has anyone experimented with this? What were your conclusions? Where do you recommend drilling?

Thanks much in advance for reading, and responding if you can.

IF the engine can breathe a little better it will perform better. How much better, you'd have to ask Bill M.

First time I've ever seen those. Will they fit a 643? Do you know how the filter is held onto the trumpet? If it just fits over the trumpet top, it could be dislodged in flight by a large bug, etc. I'm interested in them, they're really nice looking. The website doesn't have much info. on them, though, do you have anymore info., or any pictures of one disassembled? Thanks much for your time, Rick

The trumpets dont have a filter, they are a "velocity stack" the filter foam is a little sleeve that fits over the filter assy and is removable for cleaning. I'm sure the filters will fit the 643 - it's still a walbro, you take out the two carb mounting bolts install filter manifold with the bolts and then the filter housing slides on over the manifold- its a really tight fit, it wont come off unless you want it to.

There are a bunch of cool bling airfilters/velocity stacks here to.

I bought my 603 carb from them and they were good to deal with.

I have a BIG K&N from a scooter store on my gasser. I think I loose about 15 KTS in forward flight due to air drag, but it looks cool!

It has a velocity stack that bolts to the carb, then the K&N clamps to the outside of the stack. Check out the scooter store sites and tell them what carb you have. They will match the ID of the stack to your carb.

It works great in dusty, sandy conditions

I read that the walbro carbs do not do well with velocity stacks, not sure if it is true. The point was that the carb was not designed for such a smooth flow.

Personally I switched from the velocity stack that I got from Larry Bergen to the NEW Vario air filter setup which uses the same K&N filter but uses a simple sleeve housing instead of the big clunky holder with the built in choke lever. My 644 carb has the choke in the carb anyway. After fiddling with the tuning it is running really nice. I am keeping the stack in case the filter won't fit into my pending fuse project slated for these mechanics.

By the way, I was advised NOT to use the air filter oil on the KN filter for best results.

A lot of us are running velocity stacks, although a downside is, in a crash, you may suck up dirt and debris into youe engine causing a major rebuild.

There also seems to be noise coming from the carb (intake roar) that can be a litle disconcerting

It does, however, run very well, and keeps the fuel moving into the carb instead of "splashing" out.

Should you wet the air filter element with oil?

This used to be the norm in teh past. If not, why not?

thanks, Hermann

No reason not to. It will trap more dirt. K&N performance filters are oiled and can be washed and re-oiled.

We typically do not recommend oiling the filter as it may restrict the air flow too much, giving unsatisfactory performance,(my big words of the day )
