I'm not sure if this helps but I bought one of the pre-filters from D&M for the spike intake. It is supposed to be waterproof, but I have yet to prove that theory. I live on the Gulf Coast and it helps out tremendously with the sand down here. I too would like to get an answer for this particular question.

:choppersmiley: Someone on the site has to know the answer...it's the monsoon season in the Rockies, so the chances of me testing the theory are very good.:cry:

Raywood has ridden his through massive downpours, with no problem. He doesn't have one of the spike filters, but what he does have has the filter element completely exposed.

I had a Spiked D&M on my 2004 Ridge and got caught in numerous downpours and never had an issue. I searched all over at that time for the nylon prefilter and nobody was offering them. As long as the element is oiled up good it should repel the water just fine. If the filter is dry, it will start to take on water.

Okay after considerable research and several horror stories :loony: I've found a solution. The answer to my own question is 'yes'; water can get into the intake via the cone filter and cause considerable damage. The solution is a dry charger or some call it the rain sock. The most populer is the Wimmer Customer Cycles Rain Sock. Wimmer Custom Cycle intake assemblies can be found at several internet retailers and I'm sure Nelson can get his hands on them too.



Tomorrow I depart for my journey and fully expect to hit monsoon rain while riding through the Rockies. If so, I will let you know how the rain sock works.

Keep the rubber side down...

I have a Wimmer open cone style filter on my K9. I have been caught in mother fucker downpours and my engine nearly shits the bed. I did buy what Wimmer calles a "pre-filter/dust cover/rain sock" for my filter set up. I now keep it under the seat just in case.
So, to answer your question, My K9 will not run in heavy downpours. Perhaps guys with the "Spike" air filter have enough metal covering the filter element and sporting K&N oiled filter elements, as mine does not. That in and of itself might help keep enough of the water out during fucker rain storms. The filter I have with my Wimmer set up is not a K&N filter element and does not get oiled. You clean it with soap and water, let it dry and your good. It is a woven cotton filter element similar to K&N's but not oiled.

Both Knotso and I both have been in some very heavy downpours. I have a cone filter on a wimmer elbow. The filter will get saturated from the rain so when you go to give it some throttle it will cough while it sucks in the water but only for a second then it goes like it should.
Recently coming back from Sturgis I got caught in rain several times again and no problems.
Same with getting up in the morning after a rainstorm when you are at a campground without a garage. The filter may be saturated but the motor will dry it out quickly.
Oh, it's a "Green" filter which is oiled similar to the K&N's.
I don't worry about it personally!!!

:cheers:
 
i had a hyper charger, but junked, they suck. but never a problem in a down pour, and ive had to ride in few of them. k&n filters seem to really do well in rain, some coughing but nothing terrible

I took water in one time, but it was f-ing hurricane like weather in Michigan. Bike still performed but did stumble a few times.
