Nope, all that sat still. I think I want to change all the airbox sensors out though while I'm randomly wasting money stabbing in the dark for a fix.

All vacuum lines have been checked too btw.

 

Well my bike still runs like poop but it's looking better haha.

Put my rearsets and passenger pegs on today. Passenger pegs are off a 3G R6 (no exhaust mount since I have the OEM 3G exhaust).

 

Bike just gets sexier and sexier...

 

Now if only it could run right...

hmmm sounds like it has to be fuel or spark. check all the electrical connections having to do with the coils and maybe do a plug cut. by that I mean pull the plugs and make sure the all look clean and nice, but its better to put new ones in for this. then take it out and make it do the breaking up for a bit, hit the kill switch and coast it to somewhere safe, then take it home and pull the plugs. look for anything different than they were before or than the others. that will atleast lead you to what cyl the issue is in. go from there based on what you see, if its black. its getting fuel, if its whiter than others it might be a fuel issue.


just a idea


lots off food how to's on plug reading online too.

 

My old spark plugs looked good, a little out gap spec, but fine. Yamaha tech pulled them when he had the bike the other day and said they were still fine. I almost want to say it's fuel. I know it's getting spark, and I know I'm firing and in order and such. Sprayed the headers down with water and watched em. Nice and even evaporation. The only thing is sometime when it's idling it almost sounds like it's missing.

I can't prove it yet, but the other day I rode 24 miles with my gas light on. The whole time it was running pretty good. Under 4k it was great, and at 8 it was a little shitty, would hesitate for a second and then go like normal.

So I realized that it seems like it always runs well right before I get gas...so I only put a couple gallons in to see, and it's running kinda shitty again. Will see what happens when it gets low. What sense does that make?

 

Mine does the opposite and gets shitty, I'm guessing due to sediment in the tank and the ratio it's getting into the carbs. Have you looked into the tank? How about the fuel filter ? My mower had an intermittent problem like that and when I took off the old fuel filter I had to cut the line and found a piece of some plant in there that had I'm guessing been moving around at the filter entrance.

 

Yeah, that's what I mean, it'd make more sense if it ran shitty when low. My bike doesn't have a fuel filter, it's all part of the pump assembly.

I think tomorrow I'll pull the tank off and drain it and inspect the pump assembly.

 

Better pic of the powdercoated stuff, don't think I ever showed the bar ends...
