Hey all.
My Fireball is running pretty damned well lately. However, there's an issue I've been having with my air filter. I have the Ace airbox mounted, and after ruining paper filters in the rain, I switched to a K&N and Spectre re-oilable cloth filters. I never had a paper on for very long, but both the re-oilable filters exhibited the same issue: the rubber shrank and hardened, and in the case of the K&N, the oil on the filter medium disappeared very quickly, like within a ride or two.
My conclusion is that reversion is soaking the filter with gas. Any advice on how to fix this? It's the standard TM32 for a Fireball, with a 190 main (was getting fuel starvation WOT with the 185) and a P6 emulsion tube. Forget the pilot size...perhaps 25? I never changed it from the stock jetting provided by Chumma when I got it from Ace, anyhow, and it idles fine.
Do I just need to go to a bellmouth with a screen and forget my air filter issues???
