Suddenly wont go past 1/4 throttle

[Guest]

Hi all, on my way to work in the morning bike started acting up. All was good for about first half an hour was riding gently not really pushing it or anything first 5-6 miles were moving well then i hit traffic for about 4-5 miles when road opened up bike started bogging in every gear including neutral just wont go past 1/4 throttle. i looked everything over visually as but cant see anything obvious wrong with it. Where should i start looking this is on my 82 750E. Thanks in advance

Hi,

Make sure you have good spark at all the plugs. If so, then start looking at fuel delivery.


Thank you for your indulgence,

Ignitor (& trigger although they rarely go wrong), coils, plug wires & plugs. Petcock next I would think...

Petcock next I would think...

On this subject... Is there any reason why a PROPERLY working petcock would not supply enough fuel for the average GS850?? If it's working properly, it should flow plenty of fuel, right??

[salty_monk]

Yes... unless the filter is blocked or it's in fact not operating properly. You can also try running it on prime but with the tank off if you suck the vac hose you'll be able to see how much gas is coming out (watch you don't get wet feet!)

If it's working correctly then the hose will look like it's at "full flow" unrestricted.
