[Chris Jennings]

Ok rode today and the lurching came back. Seems to do it from 4500 RPM in all gears. Rode HARD this past weekend and had no problems at all. Started today after ambient temps got up around 80. It was cooler than that all weekend and it was warm when it started doing it last week. Engine temp seems to stay around the middle of the gauge. I'm at a loss. Please HELP.... Here is a recap of the original problem 93 KLR with 45,000 miles

Now that really sound like petcock pulsing or cap vent. petcock pulsing I think would be from a bad petcock hose to carb/head boot or not-so good petcock vac diaghram. --- In DSN_KLR650@yahoogroups.com, "Chris Jennings" wrote:

Some people believe problems like yours occur because the gas line between the petcock and carb gets too hot. I've seen a klr with insulation rapped around that line. I've also heard that some in-line gas filters can cause lurching. Are you running with one of these ? Could it be improper vacuum in the petcock ? You could defeat the vacuum feature in the petcock by taking out the spring and other stuff and installing a solid gasket. You could make one out of just about any plastic. We fashioned one out of a tab on a key ring. Good luck, Bogdan

Me again. Before I'd do anything else I'd conduct two simple tests. Put a spare key in the gas cap. When the lurching starts open the cap to see if that helps. Also, when it's lurching engage your choke and see if that does anything. Again good luck, Bogdan

No filter. I opened the gas cap and it did nothing to help it. Have not tried the choke thing yet. The last time I had the tank off I did disconnected it from the top of the carb instead of the top of the petcock wonder if I did anything that may have moved the fuel line closer to a heat source? I'll look at that closer and check out the petcock as well.

Anyone have experience with the Acerbis Rally D/S handguards with integrated turn signals? Sold by Dual Star. How good are the turn signals? Visibility? Wiring etc.? Thanks, Rob
