09 KLR oil burning and tested @60psi compression

Last summer my brother and I decided to buy brand new KLRs and have had a blast so far. My bike has had no problems and runs strong. My brothers on the other hand has been somewhat of a disapointment. To start off, our first oil change @1500 miles his bike only had about a quart of oil come out, if that. It has been like ever since and burns oil like crazy. He contacted Kawasaki and they said to go get the compression checked before anything was to be done. Well the results came back and his compression was only @60psi, he called Kawasaki back and they said that was not good, but not bad enough to fix. They said he should have called them after the first oil change. He has a couple months left on his warranty but he has just given up. My question is should this issue be pushed or should we just accept the fact that we bought very cheap bikes and got what we paid for?

Have a dealer perform an oil comsumption test. Kawasaki will rebuild the top end if it uses >1qt./1K miles. Take advantage of the waranty while you have it if you can stand to be without the bike for a extended period of time.

Unfortunately most of the reports I've seen say that the bike will still use oil after the rebuild. The only real cure is the 685 kit.

Don't give up. Contact Kawasaki again and if you don't get the answer you want ask for this issue to be escalated. I have spoken with a representative Kawasaki for the western states and he is very concerned about the '08 and newer KLRs. He has seen the engine problems and knows what they are and how they should be repaired. Sorry but I cannot give you his name but there are regional representatives with the same concerns.

it is to the best of my knowledge that 60 psi is not good enough to run. these bikes have high compression being thumpers and i would think the new motor would be around 150/160 psi compression. its possible the bike wasnt broken in properly and the rings have been compromised, but that would 99% of the time result in a seizure or soft seize and or broken ring/scored cylinder. its possible the top end wasnt torqued properly from the factory causing the low compression but youd be seeing oil all over the bottom end of the motor, usually. either way, its the dealers issue. press it. press the issue. it might not be under warranty if not broken in properly, but theyd have to prove it. i would think!

if you did the compression test, the tool may not have been sealing properly or perhaps it wasnt administered improperly.

i would think it would start with 60psi or if it did it would be VERY hard to start, not want to idle well and not perform well.

I dare entering a CONTROVERSIAL AREA!

IN MY OPINION, a conventional compression test on a KLR650 engine yields questionable results regarding ring and valve condition, unless historical compression test data is available for comparison.

Why?

Because KLR 650s have KACRs (Kawasaki Automatic Compression Releases). These devices crack an exhaust valve at cranking rpm to facilitate rapid initial spin-up (if you know what I mean ). Since the initiating angle of KACR activity remains imprecise, Kawasaki publishes a WIDE RANGE of acceptable compression test psi values.

Then, what to do to obtain more meaningful compression (ring-and-valve condition) information?

A. Disable KACR, perform standard compression test, compare value with typical engine compression psi values, or:

B. Perform a leak-down test.

Again, my caveat: Controversial issue, debatable opinion expressed; regardless--no offense intended anyone. And, as always: YMMV!

I'm missing something here. You said that at the first oil change, only one quart came out.

So, either it was delivered to you with a very low oil level or it leaked out or it burned off.

If it were run with very low oil, that could have caused internal damage ?

Did he keep an eye on the oil level during the first 1500 miles ?

How could only a quart have come out and he not known prior ? Surely the sight glass would have shown very low ?

Guy's, "chanceafrica" has resurrected a thread from 2010!

Check the dates before posting chanceafrica.

But to help answer your questions, concerns.

Because of mis-timed KACR's from the factory it is 'possible' that the OP's engine may have had up to 185 PSI of actual cold cranking compression with a temporarily De-Activated KACR.

There could have been numerous reasons for it to be burning oil.
