Hello all. Firstly introductions. I have returned after a long absence of several years. I traded my F650 in a while ago and have since gone through a few other bikes (a couple of R1100S and a Fireblade, which I still have). Well I accidentaly bought a Pegaso (2003, fuel injection) a couple of...

What a day! Arrived home on the back of a truck - says it all! Been going for a couple of hours with no worries. Out of nowhere there's all kinds of hiccuping and cutting out going on. The rev counter is reading like 6500 rpm when I know for a fact that it is at about 2500 tops. Any time I...

I appologise in advance for yet another question on my recently purchased bike but here we go anyway.. I notice a slight what I can only describe as surging when I accelerate hardish to overtake etc. At first I thought the clutch was slipping as the revs seemed to go up about 8k then back again...

My Dakar runs smoothly with its standard 16 tooth front sproket fitted, but when I change it for a 13 tooth sprocket (for off road use) I get a surging between 5,000 and 7,000 revs which makes motorway riding a real pain (Motorway is used to get to the greenlanes). Anyone had a similar problem...

Hi all, yesterday's fantastic weather prompted a very long ride out (two-up). Went down to stonhenge the AA sujested route and back through any road that wasn't straight :-D Anyway had a go at a long motorway stretch with my lady on the back and a topbox. I noticed something puzzling. when we...

Hi all,having problems again with surging,last time it happened the battery conections were loose and ive changed to a iridium plug,this time the battery conections were a little loose again but no joy its still the same.It seemsbetter with a full tank of fuel and worse after 80-100 miles or so...

I am aware that the early injected bikes suffered from surging and stalling. Mine is a 97 ST with carbs. When I got it, a few thousand miles ago it was a stolen / recovered one with the petrol cap wrenched open. So of course I had to remove the carbs and tip the water out. I fitted a new...

Took the 51 F650GS for a long test ride before I bought it, and for the first 100 miles or so everything was fine. Problem is, I don't know whether I've read the faqs at f650.com too much and it's psycosomatic but I'm convinced I've got the surging half of the S&S problem now... It happens at...
