Seems like cylinder 1 and 2 are the only two firing...

[Defore]

I have a 1982 gs550 with 3190 miles on it NOT 31900 I say that to cancel out valve adjusting etc... It wouldn't run until I installed a dyna s now it runs if I hold the throttle full open and the carbs have been completely rebuilt with a dyno jet kit installed. What is goin on!?
Thanks.

You still need to go in and check those clearances. There is no getting around it on a bike that is 30 years old. Sorry, but those are the facts.

So is that my problem u think?

Defore, if you want your bike to run correctly all of the recommended maintenance that is listed in Basscliff's welcome package you got must be done first.

Hi,

Spark plugs? Plug caps? Wires? Incomplete carb cleaning? Have you tested for spark? Have you tested the coils? Have you tested the charging system? What are you using for an air filter?

Even if valve clearance is not your problem, they still have to be checked sooner or later.

Yes, cuz maybe they were never ever checked,or worser, someone did it wrong! Why not find out?

Thanks.

What is going on? Some person without the required knowledge is ruining an old motorcycle.

[Defore]

Wires are good carbs are good and coils are good. Ill swap caps and recheck the gaps and go from there. But I'm reading running k&n's. And tkent02 how am I ruining my 30 yr old bike?

[koolaid_kid]

When you pull the caps, if you don't see shiny copper at the end of the spark plug wires, cut about 1/2 inch off the ends of the wires. They do tend to corrode over time and cause issues.

What setup are you running, pods, exhaust etc?..
If all plugs are firing then I would put my money on the carbs being the issue.

Check the bowls to make sure they're all getting fuel.

[koolaid_kid]

I missed that one. An easy way to see if the plugs are really firing is to run it for a couple of minutes and then shut it off. Wearing some type of glove, see if the pipes are hot. Careful, though. The ones that are firing will be a bit warm.

Also, do you have a compression tester, or access to one? You can also do a compression check on each cylinder.

[Defore]

Well the ones that fire are of course hot and the ones that sou d like there not are still a lil warm. But yes the plugs when I pull them out are all wet.

[koolaid_kid]

Have you done the spark test yet? Pull the plug, ground it against the frame or the engine, and hit the start button. The spark should be a nice bright blue and consistent, not just once in a while. This is easiest done in a dimly lit place.

^^ What he said....Using new plugs, confirm that they are firing then go from there.

[Defore]

Yes I did that and all four are firing? Now what?
