Mine burns about a quart every 500 miles when slabbing it, yes it needs a rebuild badly.

I'd suggest www.eaglemike.com for the 685 kit. He just updated/improved his whole line of big bore kits. I've installed a couple doz kits on the KLR and his new 685 has improved rings and even lighter weight piston. I was amazed at the difference with vibration compared to previous kits. Also, EM only supplies OEM gaskets. Schnitz is aftermarket gaskets and I never had best of luck with their base gaskets. If you already ordered Schnitz just substitute their base gasket for the OEM from your local dealer.

As for the head...generally just a quick lapping of the valve seats along with an overall clean up is all thats needed. I can generally get less than 5% leakage when done. Replacement valve guides are inexpensive and a good practice but I've found the OEM guides to be pretty robust even in long term oil burning engines. Its the valve seats that take a beating. Just make sure whoever laps the seats goes easy...only takes a little to clean them up.

The cams look great, as does most everything else, except:

one of the valve lifters didn't want to come out.
The piston has a nice big lump of carbon / burnt oil on it, and the underneath of the head / combustion area is BLACK. SO much burnt oil.
The spark plug was almost indistinguishable from the head, so much grey ashy crap built up on it.

The bike only has 27,000 KMs on it.

I'm liking the lower centre of gravity...
I went to 685 at 10k miles. It was not a great oil burner, but since I had a rear counterbalancer bearing going out and had to split the motor I went 685 too. The motor now has 50K miles and is going great! The valves and seals are original. Only time I needed to adjust the valves was at 2K miles - they are still in tolerance 48 K miles later.

Certainly have the head cleaned - or clean it your self and check in the ports to see if the valves have excessive carbon on their underside. If they are not too bad, you dont need to have it taken all apart. If they do, then you will have to have everything ground, seated valves adjusted and then in a few K miles the valve tolerances checked again. I presume that you checked the valve gaps before you took the head off?

There is no need to change jetting in the carb. It is fine at stock settings. Schnitz have the original assembly suggestions that Cary posted.

What you absolutely must do as the 1st step is check the ring gaps before you think of any assembly. Whomever is doing the boring might do this for you- but still check them. Also follow the post boring cleaning suggestions.

I recently cleaned up a used head which was carboned up (not as bad as yours tho!). A friend gave me a spray can of Yamaha de-carboning stuff. Couldn't believe how it softened the hard carbon deposits up - made it much easier to refresh the head assembly. I disassembled the head for inspection and found the valve guides in good condition. Suspect your head won't need anything other than de-carboning.

I have new sprockets and chain I want to install today. I don't have the right tools to break the front counter sprocket nut.off. Not the right one to put the new chain together. Here's to hoping I can find someone with the tools so I can get this stuff on my sexy beast

Everyone to their own. Each has its own personality.

A large number on this site have migrated here from the 'other' sites for a variety of good reasons. Reasons are many but also because they have, 'been there, done that'. Not actively trying to improve the KLR as a whole...? That is a wide generalization. Less tribal knowlege and endless repetition of the same issues here.

Many of the 'knowlegable' ones stay on those sites for economic reasons.

Not to concern yourself. EMike was very involved in all of the development stages of the 685 with Cary of Schnitz. In fact when Cary passed, all of Cary's technical notes were sent (Willed) to Mike. EMike is one of the very best to deal with. Either company is excellent to deal with.

Eagle Mike is the God of the KLR world in my opinion. Next time I am in LA I am going to find him and shake his hand and buy him a beer!

Certainly, your literary preference must be respected, XpressCS!

Only one question: Why are YOU here, with, as you say, such more trustworthy and superior knowledge and information available elsewhere?

Just wonderin'!



-------------------

As to excessive oil consumption by KLRs, one must agree with your premise: High-mileage engines generally consume more oil than lower-mileage machines. However, an anomaly occurred in KLRdom with the release of the 2008 models; at that point in time, even some brand-new KLR650s used excessive oil, according to their owners (if I remember correctly).

Men say further refining of piston-and-ring manufacture and design, post-Generation 2, has staunched effectively this low-mileage excessive oil consumption syndrome on later models.

What do the "other forums" say about some early Generation 2 KLR650s' oil consumption history? Excessive, in some cases, or--the same as for previous models, from 1987-2007?

A great person with exceptional business ethics. An excellent and thorough engineer too. Enjoyed many long technical discussions with him. Another is Bill Watt - of T-Bob fame. Bill and Mike worked together on the T-bob and Mike does the milling for it.

His shop is in San Diego, you missed by 100 miles or so.


Mike really is an extra-cool guy. Generous and helpful to a fault.
The Oracle of all KLR mechanical knowledge, for sure.

Entertainment value dear Watson! And Shiny Things draw my attention.

I don't pay attention to the 2nd gen bikes, they're fugly But I do know the 08 models had a particular issue. Most gen1 owners switch to the 685 kit to cure their oil thirsty engines.

More specifically in El Cajon. He is now within reasonable driving distance of me now, er that of which my butt can handle on the KLR

Went to a friends who is very smart with motorcycles to install my chain and both sprockets today. It went way easier than I imagined. I basically did it.all my self too which was awesome. He just gave me pointers, frimded off the old chain and I took care of mostly everything else. Im very happy. Got a new 15t front and 43t rear and an x ring chain. No issues with the installation or putting the cover on for the counter sprocket. Those wires up front are VERY tiny and I can understand how people can pinch them or get them disconnected.
