Re-drill the mounting holes 90 deg on the cover so the louvers are pointed to the rear , did that for a shovel running that Compufire ign. having similar problems once haven;t heard from the owner about that problem again .

 

I thought of that but the relative wind passing over the louvers would create a lower pressure inside the nosecone that would surley suck water in during a rain shower. Maybe your customer never rides in the rain? I was thinking more about some type of membrane below the louvers that would allow air to pass through but not water. There are "hydrophobic" membranes available which are used in high end waterproof devices. These are devices that need venting for heat dissipation or atmospheric pressure differentials but still need to be completely waterproof down to a depth of a meter or so.

Something like Gortex (will breath and has a certain amount of water resistance) might work also, but I'm just not sure it would vent air sufficiently.

Maybe I'll look it and I'll make the million dollars, LOL!

 

Funny thing is I leave the gasket intake behind the cover on all the builds I've done whatever the ign. system used and while some of them have crapped out it isn't because of water and I doubt heat is invovled to any degree . Some name brands & models seem more prone to faillure than others is about the only common cause I've really found over the years .

On an evo or shovel unless the front exhaust pipe is slammed up close there shouldn't be that big a heat problem with the ign. systems and if what your running is that finicky about moisture & heat I would suggest looking into a more user oriented ignition system period . I've never been a fan of Compufire nor the Dyna2000 series for those and couple other issues just too damn touchy for a hard daily rider and for the average guys bike there's zero gain aside from bragging rights . Worse hands down is anything Thunderheart they have made nothing but junk , good idea but but flaky hardware .

And ya could be since we live in CAL. the dude doesn't ride in the rain but guarantee he washes the hell out of it regular .

 

Went with the Daytona all is up and running great again took some tuning but running good now
