Did this upgrade about 2 1/2 years ago or about 23,000km. I have to say it completely fix the oil burning issue, now not a drop. Always nice to use a forged.
I have installed a couple of these over the years and it still remains the best big-bore kit for your KLR. It includes everything you need, from gaskets to a comprehensive instruction set.
The first kit I installed was on my own bike, years ago. I have now done more than 90 000km since then and the bike still doesn't use oil.
Thanx for doing the KLR community a great service.
The only question you will ask yourself is, why didn't I do this sooner. The toughest part of this rebuild was finding a machine shop to do bore and hone, because it is a large bore job. It's just over 4" and the shops around here didn't have a bore bar that large. You are going to be amazed at the extra power... Not a tub, but enough to ease up the front tire in 2nd gear... Mine never did that before. Another and quiet. Might as well get the thermo-Bob while you have it torn down. GET THIS KIT!!! You won't regret it!
I ride this kit for 6 years, still delivery strong power, no oil consume.
Hard trail, including Moab.
I found the pictorial guides indispensable. I did struggle with carb removal in tearing the engine down, and avoided the battle on re-assembly by simply removing the rubber boot from the intake manifold, attaching it directly to the carb, and then re-attaching it to the engine.
Very high quality kit! Went together easy with one exception, wrist pin clips were a pain. Please include tips on installation... Runs great!!
