Stuttering at constant speed
Hi there,
My bike does have problems with constant speeds.
When I am cruising at speeds like 50mph and 30mph the bike stutters a little.
Like I am playing with the gas constant.
with 30 its stutters harder then 50.
Bike acceleration is fine. The bike drove a total of 17 945 miles.
Who knows what this can be and how I can solve it?
Thanks.

It's hard to get them out the engine.
You get handy in it but it takes a while.
I will check the other 3 another day.
What if they are all good?

I mean that thing at the top off the sparkplug:

if all 4 plugs are the same brownish color, then it means the carbs are delivering the same correct mixture in all 4 cylinders. If one is white, it is running lean, or coolent is entering the cylinder. If it is black, it is running rich, or oil is leaking into the cylinder.
The cover on the top is just an adapter, so your leads fit onto the plug.
Some other leads on other types/bikes you have to unscrew the adaptor, for the leads to fit.

What should it else be?
BTW it also looks not running smooth in idle.
