After my bike ride today I decided to pull and check the air filters, no issues but living in the desert I've made it a habit to keep an eye on them. I also decided after reading threads on here to run Seafoam through it, again, no issues just maintenance. After I get all done with it, I put the filters back on and take it out for a ride. 1st gear fine, 2nd gear fine, shift into 3rd and the bike falls on its face. 4th gear and still nothing, really wind it up and it starts popping and backfiring, even worse when I let off the throttle.
I pull off the road and come to a stop and let it idle, snap the throttle a few times and she is all there, no hesitation or backfiring at all. I take off and again 1st and 2nd gear she's all there, hit 3rd and she's done again. I start thinking that I fouled a plug or something since it sounds like most of the noise is coming from the left side.
I head back home and go back over the filter housings and vacuum ports to make sure I didn't leave anything loose. Can't find anything so I figure I'll just pull a plug in the morning and deal with it then. So I go ahead and button up the lower fairing and while I'm doing that I look at the filter housing and start to think what are the chances that it's getting too much air without the fairing blocking the fronts of the filter housing. Crazy thought but I figured what the hell, one more quick ride to see. Sure as **** she runs like a raped ape again.
Now is that normal or could something else be going on? Seems strange to me but it runs fine so.........
