Okay all here we go AGIAN!!???
Quite a while ago I thought I started a thread about this and thought the problem was rectified BUT I guess not. I'll try to keep it short any help would be more than appreciated. I'm sorry but I couldn't find the original thread that I posted so here goes:
Since I joined the board I have been grappling with this issue and I am pretty much at my wits end.
I initially thought that I had a "water in the fuel lines problem" but I'm not so sure that's the problem now. In a nutshell here is the problem: When I am cruising along at above 65mph for any length of time ie. more than 2 minutes or so the bike starts to peter out. What I mean is that I'm cruising along happy as a clam about 62 mph or above and then the bike feels like it starts sputtering and losing power more and more. If I just hold the throttle in place sometimes it will sputter a little with the concurrent lunging and dip of power and then subside and run as normal. Most recently, yesterday, the same thing started to happen and I gave it more throttle and the power loss leveled out, but the engine sounded like it was popping or sputtering but deeper toned. So I held the throttle there and the first time it subsided and turned back to normal operating power and sound wise. The second time, as I was cruising along about 62-3mph it happened again but this time eventually puttered out and I had to stop. Upon several cranks of the starter and a few revs it did start but sounded still starved for fuel but eventually returned to normal. Arrrgghhhh I don't know what the deal is and I don't feel good about riding at any speed above 55mph because this keeps happening.
So far this is what I have attempted to do to remedy the situation:
1) A mechanic told me to drain the carbs due to the possibility of water collecting in them. Action)Drain the carbs. keep the tank almost always full and turn off the fuel when parked.
2)Problem still arises occasionally. Action)Keep draining the carbs fairly often. Result) Problem still arises
3)Fuel additive (HEET to be exact) regularly added when tank full or not and the problem still arises
4)Join this board find out about Sea Foam problem still arises
What I have assesed and what I feel is not an issue.
(I am not a well accomplished wrench but know my way around the toolbox)
1)The tank is in good condition, no rust, gunky stuff or other in the bottom from what I can tell.
2)When the carbs are drained there is nothing fishy about the fuel coming out of them. ie. no particles, discoloration etc.
3)Have tried several treatments of SeaFoam, not a full bottle treatment yet but close.
4)I have run the tank on reserve just to make sure there's no bad gas in the bottom of the tank.
Next plausible solution that I can gather is to run the tank almost totally dry of fuel except for the reserve, and add at least a whole can of SeaFoam, run it for a little bit to make sure the bulk of the SeaFoam is in the carbs and let it sit for a while. Then later on fill up the tank and keep my fingers crossed.
