...and after lunch I topped off my tank on the center stand of course. It was super hot out (95+). We were headed up the hill, goin hard when suddenly I lost about half my power. It stuttered, went hard again, then repeated the process. One of my buds stayed with me, the other two were off on an after meal food high, so we stopped for a sec, teeing to figure out what it could be. We took aft, hoping it was bad gas, or a clogged jet or so ethnic and would clear itself at high rev. Surprisingly, after running at a consistent speed for a while, it did seem to correct itself. I rode the rest of the afternoon, with no problems. Then, on my way home, same thing, except this time after stopping for a minute, I took off and it tried to die, sputtered, grabbed and if I feathered the throttle it would start running normally again, unless, I got on it hard.
This is what I know. It was definitely brought on under high temp/revs. Then seemed to correct itself as it cooled. My first thought was coils, but I have never heard of coils failing on a gen1. So that leaves fuel right? Bike is fairly low miles (18k), so carbs should be fine.
I got home, dismantled the top and checked all the fuel and air lines. Checked all the wiring for grounds and arcing. Took off the fuel filter and blew it clear. In the end I ended up with the fuel pump in my hand. This is one of those ridiculously expensive Mitsubishi ones, so Im Standing here trying to convince myself I'm wrong. Am I?
Really would appreciate any input you can give. Checked spark by the way, and it's good, but it's cool now and at idle... I took out the air filter and it's dirty but not bad. There is some king of tube that ends inside the air box that seems to be leaking a little fluid that kind of smells like gas. What is that, an overflow filter or something, to keep the gas smell away? Anyway, off topic!
This bike has never had problem one. So I'm left praying it's not the clutch, although this would be the oddest way I have ever seen a clutch go? Only slips at high temp and revs? No, that's impossible now that think about it because of the instant power loss. If the clutch was going it would scream up in revs, right? Gotta be fuel!
What do you think? O mighty forum gods?...
