Dear gurus,
I'm the proud owner of an '88 K100 RS as of 3 weeks ago.
Since the purchase I've mainly been riding her to/from work to "get her going again after she spent years in a garage with very limited driving. A few issues as they have surfaced, I have been able to address them so far.
I have still not had the time to do the "preventive maintenance after purchase"-tasks that is well documented on the forum.
I'm seeking your advise on a few topics :
1) I experience an intermittently (and temperature sensitive ?) dead speedometer.
I am quite certain it's the electrical connector, If I tough the cable bundle while driving, it'll come back to life, but I have to do this while keeping my eyes on the road.
Can someone help me identify which connector / wire is the speedometer one ? (see attached pictures)
2) I had to access under the fuel tank to repair a leak, so I disconnected the fuel pump connector. After putting it back together, I experienced on 3 occasions a 'surge-effect' on relatively hard accelleration that I would thought was low-fuel, but I had 6 liters left in the tank when I filled her up. As I didn't have this problem before messing with the tank, I suspect the connector. I have not been able to reproduce the problem.
3) There are 2 lines coming out of the bottom of the gas tank. Overfill evacuation and ventilation, I presume ? They currently don't have rubber tubes running down past the engine block, as do my other bikes. Is this normal ?
4) The attached picture shows 3 tiny tubes with rubber caps on them, behind the injectors (next to the throttle assembly ?). The rubber caps are cracked and I doubt they provide an efficient seal. What is this ?
Your input is highly appreciated.
As I am just starting (little by little) to get my hands dirty and lacking confidence, I hope you can bare with me on these basic questions.
Best regards,
Einar.
