Food for thought,
The MC Mod advances the Exhaust Cam shaft. The Exhaust Cam Shaft has the Kawasaki Automatic Compression Release (KACR) attached to the R.H. end.
If for NO Other Reason, owners of reluctant Cold Weather/Cold Morning starting 2008 and NEWER KLR650's, Should Consider This Mod!
Case in point, '09 oil burning KLR650 29,435 miles. 88 PSI, Cold Cranking Compression.
Recent Schnitz 685cc rebuild, with valve seats as 'Perfect' as I could justify. OEM gaskets, not the oil leaking 'Hi-Compression' Cometic Gaskets.
MC Modded, (exhaust cam advancement), Freshly assembled per Schnitz Instructions, (As in, I can't believe how DRY they want this thing!) NOT Yet Started (Wednesday 4-29-15)! 124 PSI.
Started instantly! As in, was at TDC compression stroke. 2 full rotations of the engine, 4 Cycles! Down on the 'dead' power stroke, Up on a wasted Exhaust stroke, Down on the Intake stroke (full carb, on full 'choke'), UP on the Compression stroke and Running!
Rode it a 100 miles Thursday evening and changed the oil and filter.
Modify at "YOUR OWN RISK"!
Still riding my 1987 KL650-A1. 85,000+ miles & counting
