I was 50km from home and ready to roll. I had my daughter on the back. I went to go and the engine kicked and spluttered. I couldn't get it to rev over 1500. Being on a slight hill I could barely get it to even take off.
Two and a half hours later, I got home. It took me a while to suspect the throttle position switch but once I did, I got the hang of riding like that. With the computer thinking the throttle was closed, the motronic wouldn't allow revving but still had a small range of adjustment. I figure that when I rolled the butterflies open it tried to richen the mixture which gave me a sort of fake throttling. If I opened them too far, it would pulse and kick till I backed it up but I could go up gears and it would gladly give me enough power to stay there. I could not manage any more than 29km/h (yes, I stared at it for two hours ). This was level or downhill, unless the downhill was steep enough to disengage the clutch and roll.
This morning I decided to test my theory. I looked up the clymer to find out where this switch is, reached down and flipped the clip and pulled the plug. Just like that the engine started and ran like normal.
There is some corrosion on the connector but I may just pull the switch and clean it out.
