<><><><><><><><> <><><><><><><><> Luc, Sorry for the late reply but I've been on the road since Wednesday morning and just got home this evening. To the best of my knowledge if your KLR650 is running well you don't need to do anything more for the 685 install than resize the cylinder and resize a new headgasket (the hole will be too small on a stock gasket) and reassemble with new o-rings and gaskets. Carb jetting and valve clearances etc should be fine as is. Oh, coolant change would be needed at the same time as the 685 kit install. Stuff you might want to consider could be new valve seals since the head will be off. I think cost of each seal is about $11 or so and you'd need four. A Thermo-Bob is a good add on for a KLR as far as I'm concerned. I know Wattman and he was instrumental in helping me information and advice with both my Thermo-Bob like stat housing construction and the dual radiator conversion on my bike. I know both mods work and I think the Thermo-Bob should garner serious consideration for bikes ridden in temps below 70 degrees. I suppose a doohickey check would be easy to do if you felt like it as would an oil screen cleaning. I'll be adding a torsion spring to my KLR when I do my 685 kit. I swapped an EagleMike long doohickey spring for a short spring about 3 months before the torsion spring became available. It's finally time to add the torsion spring with my next engine work. If a guy wanted to do head work for more power that could be done. I don't think the cost is worth the results so won't be doing it to my head. Hope this is helpful.

That's a pretty subjective view there, Jeff. You're looking at more than a 7% (41 vs. 38 horsepower) peak increase according to this chart: http://www.patmanracing.com/Image%20host/eXcel-dyno-chart-A.jpg This page is pretty comprehensive regarding power gains through different mods: http://www.patmanracing.com/klrdyno.htm Looks like it is pretty evenly spread across the whole rpm range, too.

<><><><><><><><> <><><><><><><><> Stu, Yup, subjective alright. : ) I took a very quick look at the dyno results. I didn't see where headwork along was documented. Although the dyno results show improvement I stand by my view that the head work isn't worth the money to me. The 685 kit is worth the money in my opinion if a person wants to stop an oil burner or gain a little extra power. No matter what mods you do you still basically have a KLR.
