- April 13, 2015, 18:23:59 PMI don't think it's an injector, since the fuel pressure goes up under a heavy load, due to the fuel pressure regulator. I would be more concerned about ignition issues. How old are the plugs? Is this more noticeable on a damp day? Heavy loads and worn spark plugs will make a miss fire that can really feel interesting. Since the 1500 has dual plugs, each fired by a separate coil, one of the plugs miss firing could give you this feeling. Damp days and 15 year old plug wires don't mix well. Possible one or more wires is leaking to ground. Again, a heavy load will reveal this problem. The fact that there is no issue when operating at reduced load indicates an ign. problem.

- April 13, 2015, 17:32:15 PMI have a strange fault on my 1500 drifter and just wondered if anyone else had experienced it. The fault is under hard acceleration and only in second gear the engine suddenly surges starts pulling then surges again, it is quite unnerving especially if you have a pillion. During normal riding it behaves as it should,just under fairly hard acceleration. Any suggestions would be most appreciated.
