Another K75 no start
Have a 1988 K7s, around 50k miles. Have had ZERO trouble with it until about three weeks ago, started acting funny, like it was running out gas or something. It would start, then run a little rough or idle really low, then it would die, if you didn;t stay on the gas. Now it won't fire up at all.
Checked the battery, was just replaced in August, Has full charge, and test shows has good charge when bike is being started. Looked at plugs, they have some carbon fowling, but look good otherwise. Plugs also showing they are getting gas. Fuel pump runs, as does the starter. I did the starter test, tapping brakes to see if dash lights dim while starting, nothing noticable there. Checked the fuses in the fuse box, they're good. I did replace the crankcase breather hose, since it was badly in need of it, and was partly responsible for the rough running condition and fowling I am guessing.
I even put the bike in gear and rocked it backed and forth, after which it sounded like it wanted to fire.
I have pulled the ignition coils off, with the idea of taking them to the dealer for testing, thinking it may be something there that needs replacement. I plan to clean up the main ground as well. Other than that, I am at a loss. If not the coils, next step is to take it in to the shop, hoping not too, since it might be expensive.
It's been a great bike to this point, and hoping that I can experience the bullitproof reliability that I've heard so much about.
Any help appreciated,
