jaeger, i run the open at both ends airbox and open uni filter and have no compunction running rain sleet or what ever. the s.o.p. preformance was immeditely noticed (132/45/2;modified first gen tor's) (i want to try different needles(thruxton?) and drilling the slide(?) for throttle response) however, as mentioned before the filter gets dirty quickly and when she's dirty the tuning goes south. makes sense as you tune with a nicely oiled clean filter and a few weeks later she's gummed up. i am happy with the results even with the added chore of staying on top of the filter cleaning. better yet tune with a dirty filter and you'll happy at least 50% of the time!!!!!!!!!
