My Bike is Losing power

Hey my Honda VFR 400Z is losing power from 2nd gear go up

as the gear increase it slows down

no problems starting


so is it a Gas Or spark Plug Problem

out:

 

type of bike i ride

 

Really? where you at? Sounds like a fuel thing to me, look at all fuel lines filters and valves, even inside the tank for crud. But with out actually riding it, be hard to say for sure. need a bit of history too, has it been sitting? Hey here's an idea, sell me your bike? then I'll fix it. by looking at the photo must be a pre 88? carbs? looking at the wheels my guess is 84 - 87?

 

I love those dual headlights

 

Yeah thanks for the help
i will try it soon

 

Wow man that's a frickin cool bike, I haven't seen a naked one like that before!

 

you may find this a bit wild, but ive seen leaky or cracked CV diaphrams cause similar problems, this causes the slide to not open or open enough under load.(the rubber diaphram connected to the slide in each carb) and i second the fact that its a cool bike!!!

 

Nice bike...
Change the plugs and see what happens. It could be a fouled plug.

 

Hey you were right

there was something like sand in the fuel lines

dont ask how that happen

i would of never think of that so Thank you very mucheace:


And thanks for all your post..............i tell you how happy i ameace: eace: eace:

 

Can you post some more pics of your bike? That is the look I wanted with mine. But I couldn't get it together in my head. You seemed to have the same idea sooner and got it pulled off nicely.
