Crazy Rev Counter

[Manxjim]

Hi All!,

Just took my L1 for a blast to the dentists, and noticed the rev counter was reading along at 8000 rpm, when I was barely revving the engine. Took it out the road, really openned the throttle, and the neddle went past 16000, but the engine wasnt doing more than about 10 I would guess, she wasnt screaming at the red line as the roads were wet and the tank was almost empty.

Now, I have recently (6 monthes ago) added new headlight bulbs, which are higher powered, philips xtreme or something, 60/55 rating.

Havent had any issues till today. Any ideas what may be causing this? I did a search, but didnt find anything readily useful.

Cheers!

A few people have had this issue, and common issue has been the battery.

Prob worth chacking the connector blocks for cleanliness and see if that fixes the issue first.

check your CDI and fuel pump relay connections, the feed into the tachometer comes from there.

As Rob said, usual suspect for erratic rev counter is duff battery
