Goldsboro, NC | Hey, all.
This problem has been getting worse... has been going on for about 6 weeks.
I start up my bike after work. I let it idle for 3-5 minutes. I gently run it about 500 yds to the traffic light, where I always sit for a minute or two. Then I turn onto a divided highway and run at 70-75 mph.
About a half mile to a mile down the road, I start to lose power. If I let go of the throttle and hold the clutch, the engine stops and I coast. I can start again by using my momentum to fire up the engine. Repeat one or two more times. The second or third try, I get a huge backfire and the engine runs well the rest of the way home.
I have also noticed that my fuel economy is 'way down.... about 30 mpg.
2008 Vision Tour premium, full stock.
Any ideas about what I shoould look at?
Thanks.

Jasper, MO | Two thoughts. How old is your air filter? A dirty air filter could cause some of those symptoms. Check the fuel pump pressure. It might be getting weak.

| Loud backfire comes from weak eletrical or coil or spark plugs.
So how old is the battery loose conection or plugs being old.
Maybe fuel pump but I dought that. |

Gainesville Fl Home of the Gators | Yup....time to check fuel pump. Insufficient pressure to atomoze the fuel causes low MPG, and loud backfire comes from reintroducing spark; to a flooded chamber. Should have 49psi |

Goldsboro, NC | So. I just had my fuel pump replaced, courtesy of the fuel gauge float drowning. Shouldn't be that. I threw up my hands and took my baby to the stealer. He claimz that it was the voltage regulator... for $300 diagnostics parts and labor
I'm inclined to agree. Anyone care to warn me I've been sold a bill of goods? |

Gainesville Fl Home of the Gators | Ummmm...yea.......not seeing it causing a performance loss issue without wildly swinging volt needle. Also there is an axiom in the repair bizz....New breaks too; that's why they make things everyday

| When you say loss of power, do you mean the bike is sluggish and anemic, or the electrical system is momentarily shutting down?

Re-reading this thread. I have to ask the same thing myself |

Loss of power at speed
