In gear, the engine can be heard to be increasing in speed for the first few hundred or so RPM above idle, then the vehicle suddenly jumps forward. Makes for a very dodgey time trying to get this up ramps onto a trailer cross-ways. On the ground, the vehicle is fine once the system engages.
The owner reports the vehicle has always been like this (bought used 6-8 months ago, approx 1500 km.) He thought it was sticky throttle cable. I don’t think so.
Since this was first noticed by the group, we’ve driven 1000 km across Newfoundland on the old rail-bed in 12 days. The problem still evident, but no worse. (800 was actually pulling a small ATV trailer for about half the trip.)
I suspect a clutch issue. I’m a capable mechanic with zero experience on these machines. Any thoughts?
Thanks a lot!
