I vary between 240 and 300lbs, usually at 270. I have done a few 750 mile days on the stock seat, but 400 miles is really the limit of comfort. I have been using a flat Corbin for the past 7 years, and I have done a couple 1000+ mile days, and many, many 500+ mile days. It is so comfortable for me that the factor limiting my riding distance is my eyelids more than my ass. Mark

Does the KLR have a device that automatically releases compression pressure when starting. Old Brit singles had a manual switch that opened the exhaust valve slightly to make it easier to turn over the one big piston. Do we have something similar? If so, where is it and do you really need it? Dave

Yes, It's called KACR (Kawasaki Automatic Compression Release) in KLR lingo. It automatically props open a valve at engine speeds under around 600 RPM. It is internal to the engine and (in my experience) largely maintenance free. -Jeff Khoury From: "hgyrmliun" To: "DSN KLR650" DSN_KLR650@yahoogroups.com> Sent: Wednesday, June 8, 2011 8:05:59 AM Subject: [DSN_KLR650] compression release on starting?

Yes. It is called KACR (Kawasaki Automatic Compression Release). It is on the exhaust camshaft. A pin along a lobe for one of the exhaust valves increases the duration the valve is held open thereby reducing compression until the engine gets up to somewhere around 800 RPM then the spinning counterweights move the pin out of the way of the lobe for normal operation.
