Good question!So What are the differences in thermo’s being sold? Watt man v Procycle
Thanks for sharing! Glad your engine endured those miles before the modification.Somewhere between 60,000 & 63,000 miles around about 2011-2012, IIRC.
Damocles, Yours is the First I've heard of anyone suggesting the addition of a Thermo-Bob would correct the so-called "ovalized" bore. Did you just make that up? Interesting thought non the less.Thanks for sharing! Glad your engine endured those miles before the modification.
Back during the excessive-oil-consumption disaster of 2008-09 models, some opined the lack of a Thermo-Bob was responsible for this oil-guzzling phenomenon. Others insisted (and, probably still insist) the lack of a Thermo-Bob results in distorted (i.e., "ovalized") cylinder bore cross-sectioning. Don't know if those of this persuasion consider installation of a radiator bypass corrects this bore anomaly or not.
Regardless, the Thermo-Bob appears responsibly marketed, performing as advertised (stabilizing coolant temperature more fully and at a higher nominal operating temperature than the OEM cooling system), AFAIK. The 100,000-mile 2008 model of my riding partner proudly sports a Thermo-Bob!
In my post, I intended disclosing my own ignorance of whether the concept was harbored by anyone or not:Damocles, Yours is the First I've heard of anyone suggesting the addition of a Thermo-Bob would correct the so-called "ovalized" bore. Did you just make that up? Interesting thought non the less.
Does the lack of a Thermo-Bob distort engine cylinder bores? On ALL KLR650s running without radiator bypasses? If so, in the service life of KLR650s, early installation of Thermo-Bobs appear critical, if the ovalization is not corrected by the device.
If a radiator bypass only PREVENTS cylinder bore distortion, I'd wonder whether any non-Thermo-Bobbed engine has a symmetrical cylinder bore; if the bore geometry remains true without a bypass, I'd wonder why. Don't know if the vendor claims avoidance of cylinder bore distortion from use of the product, or offers any test data to that effect.
Just for the record, I think evidence suggests incorrect piston/ring design and/or construction was responsible for the excessive oil consumption of the circa 2008 model KLR650s, not the absence of Thermo-Bobs. What evidence? Fewer instances of excessive oil consumption reported after re-design of pistons and rings by Kawasaki, say, on circa 2009 and later models. My opinion only; YMMV!
Just curious, dallas (I basically favor a, "free market"), what factor(s) influenced your preference for T-2 over ProCycle?After further review...I see that the T-bob 2 is similar to the ProCycle version I purchase in March 2015. If the T-2 would have been available back then I would have purchased it instead.
