copper canyon 2008 trip report

Here's a link to my recently-completed ride in Copper Canyon: http://www.advrider.com/forums/showthread.php?t=315178

2007 with K&N air filter seems like it is starving for fuel when run at 70 (speedo) mph for more than a few minutes. The bike will hold back then run and so on and so on. The only other carb mod I have done is the tee. I live in Florida but I do not think the heat has anything to do with this as it will do this on demand in any kind of weather. I have removed the carb and tank and cleaned them and the petcock thoroughly in case it was dirty fuel but the problem persists. It is not like I drive at this speed everyday but when I do it is really aggravating. Any thoughts would be helpful.

Make sure all carb and tank vent lines are clear and flowing freely. You mention the K&N, did this problem start when you put the K&N on? If so, it might be over-oiled. Try the stock filter to see if the problem persists.

Have you tried putting the original filter back on? If so do your symptoms persist? K and N filters are less restrictive and would generally make your bike run leaner than normal. Alan A13 Ia Russ Coley wrote:
