First I'd like to say I'm not terribly mechanically inclined but I want to learn. The most I've ever done one my scooter is replaced the mechanical seal in the water pump. I bought the scooter used and have been riding for a few years. My brother replaced the rollers and the belt for me about 5 months ago, and I haven't been riding it for a couple months now. (I got a motorbike and was riding it during the summer.) Now the weather has started to go so I'm back to my little buddy.
The Problem:
It's happened 3 times now, twice on the highway and last time when I was leaving my driveway. I'll be riding at about 60km/h and about 7 or 8 thousand revs when all of the sudden, I lose power and my revs drop. It idles a little lower than usual. When I say lose power I mean I can't get going any faster than maybe 5km/h. When I get off and put it on it's center stand and rev, it doesn't go above 6.5k. I don't see anything leaking and for the most part it sounds the same (the first two times the after-market exhaust sounded a little softer than usual.) There is about 20,000kms on it. (I don't know the exact number, my speedo cable snapped off a while ago and left a piece I cannot get out in the little socket where it connects to the front wheel.)
Has anybody had the same problem in the past with it just dying like that? The first two times I just had to turn it off and on again and it fixed itself.
Any suggestions are appreciated. Thanks.
