Exclamation BIKE LURCHING?

Ok so I'm getting ready to go to work this morning I do my pre ride check list and all fluids are within range. I ride off down 1960 and have no problems bike is shifting normally and running smooth, as I merge onto the I45 HOV I accelarate to about 50 and there is a bus infront of me going about 35 I attempt to pass and about half way past the bus it's like the power wasn't there I managed to pass the bus safely but as I try to accelarate away the bike is struggling at around 60 mph if I roll on the throttle more I'm actually losing power and speed. So I find a sweet spot where the bike maintains power but it seems to be lurching between losing accelaration and gaining it I know I'm not low on gas cause I filled up 2 days ago and the bike was not ridden yesterday but for a few blocks to Motorcycles Unlimited for a new tire the bike was not overheating and like I said oil is within normal range so what could be the issue? is it my valves? carbs? what?

Fuel filter or carbs of you have them. It sounds like dirty carbs to me.

Carbed? Clean the carbs.


FI? Check TPS signal for dropped signal(fuel injection slows, starves bike) or fuel pressure(ok at idle, low speeds but no volume producing pressure when bike demands more)

If its carbed you dont have a pump. Its gravity fed.


If its sat, likely gummed up carbs. You can try running seafoam through low tank to get to the carbs immediately to clean it up on your ride home but only way to cure that is to disassemble, clean the jets/needles and reinstall, sync etc.

Fuel filter is easy to bypass w a straight hose if you wanted to rule that out or take it out, blow through it in one direction. It will likely be ok and free flowing.

Thanks i'll try the seafoam route first if that doesn't help then I guess it's gonna be time to clean the carbs hopefully someone knowledgeable can be there to help me out

Pull the drain screws in each bowl. Use a straw on a can of Barryman chem tool. Let it sit 5 mins. and then drain it all out. You may need to repeat it a few times. Dont get that on the paint.It will clean that up without pulling the carbs.

Unfortunately if its already in the carbs, they are done. Bluewave has a good idea.

Sounds like the water/gunk that floats ontop of gas made way to the carbs.



Talk w DaveC about Saturday. Im not commuting w tools but if he has basic hand tools and you take the carbs off we can do a minor rebuild. Get about 3 cans of good carb cleaner, small water bottle to soak the carbs in and I'll bring some metal needles to clean the jets. Anything else or immaculate cleaning see Motorcycles Unlimited

On mine, if you run it long enough at the sputter spot it will eventually start flowing. But everytime you ride you'd have to play with it at that point/needle injection.
