'94 CBR 900RR Backfiring
So I came home Friday night from College for Thanksgiving week, and I started up my bike. There was fuel pouring out everywhere. My friend and I noticed it was coming from the carbs, so we narrowed it down to the o-rings on the fuel tubes that go into the carbs from the fuel lines. We replaced those and it there is no leak. Before this happened, my bike used to have a power decrease in the 5-8,000 rpm range or so, and then it would kick back up. Now after taking the carbs apart to replace the o-rings, the powerband has completely changed and I get a whole ton more power and it seems to be going the way it should be. It's no longer whimping out on me, however, now when I let go of the throttle, or downshift, it starts to backfire. Because my friend dropped my keyes under the tank the last day I was home in August, he came over a few weeks ago to take the tank off to get them, and he called me up asking where a hose should be attached that goes from the front of the air filter. I don't remember seeing a loose house before when I was working on it this summer, but when I looked at it on Saturday it was there. It just goes around the air filter and leads to nowhere. Also, there are some carb vent tubes that go to a plastic housing, and it has a port for the same size hose as the loose one, but there is no way it can reach it. Basically I'm trying to get rid of the backfiring, and thought I'd give as much info as possible to the circumstances. Thanks for any help and advice!
