Well folks, here i am again with the bucking problem. I set out on my 86 k75 last week to head up to montana for some good old brick-camping and hanging, annnnnd the bike sputtered to a stop on a mountain pass. Heres what happened and what i think, but im still new to my brick so id like to run it past yall. I was going around 70-80 (speedo dont work) and felt a little bump, like a buck but tiny so much so i thought it was something i went over. Then about a 2 minutes later, again, and again with increasing intensity and speed and as they increased i slowly dropped rpms, to the point where i was wide open and had nothing. Pulled over and the bike died, couldnt get it to start back up. So i post up, smoke a cigarette and try her again, and boom shes all good, though my first thought was vacuum leak so i look around the bike and find a single drop of something. stayed by it for a while longer to see if i was leaking and where from but cant find it and dont see any more mystery liquid I limp, keeping the rpms under 3000, the 10 miles down to butte misfiring the whole way and here i am. Now i reckon its either a fuel problem or a vacuum leak but those are both aspects that i refurbished when i got the bike.
New pump
new filter
new fuel lines
refurbished injectors
new rubber bits all around
etc etc
And body got a lead? I read someone had power loss when his exhaust valve went out, but i did a compression test before i left and clocked in on all 3 with 145. Also when i left i had a good amount of oil above the dot, now i look through the view glass and its at the dot. Could be unrelated but i thought it was strange. Taking the bike down to slc tomorrow where i can use a garage for the week.
