Options for oil consumption problem was created by xplorer
I have searched this forum and others, but most of the info is older than six years old.

My 2012 model with 68500km oil consumption has now become ridiculous so I need to consider all options.

I have been recommended to get the Schnitz 685cc upgrade kit at US$309 ex-works USA with all the gaskets, or $376.15 including shipping to SA.
I could do the installation myself but might consider paying someone who has done it before, depending on costs.

But what other options are out there, and their associated costs?

I am less concerned about power increase and much more concerned about resolving the oil consumption once and for all.

Over-sized piston and rebore the cylinder? Cost thereof?

Any other options to consider?

Keen to meet and ride.

Out of interest:

Did you buy the bike new?

Service intervals and which oil did you use?

Which air filter are you using?

What is the current oil consumption ?

My bike is approaching 105 000km so this thread is of interest to me.

Did you buy the bike new?
Nope, it had 12000km on the clock.

Service intervals and which oil did you use?
All according to the manual.
Castrol Activo

Which air filter are you using?
Original air filter.

What is the current oil consumption ?
About 3ml per km

Blue smoke visible upon hard acceleration under load, especially uphill.
No smoke upon cold startup after standing overnight or longer, so I do not think its the valvestem seals.

I recently changed over to Actevo and the consumption went down significantly. Over the 3000km since service I had to add 500ml which is a big improvement from what it was.

Good luck with your decision.

Chat to Jorge AKA CapeKLR on this forum. I have done both Schnitz 685 and 0.5 mm OEM Kawa piston and TBH the OEM Kawa bike has lower oil consumption than the Schnitz.
If you do want the extra power tnen Schnitz is the way to go but you can go smaller and leave space for an extra re bore in the future if needed.

My opinion is that the reduction in oil consumption is due to the quality of the engineering and the way you run it in afterwards, which is why I would suggest you contact Cape KLR or Groenie to make sure you use an engineer that knows how to clamp and machine a KLR barrel.

This is the most important part of the rebuild. I have had barrels rebored where the bike then used more oil after the rebuild than before.

and the way you run it in afterwards,
Also important, but the engineering work is more important.
