In Ecuador. KLR excessive oil usage gen 1. Piston/ring kit?

Fellow riders, I am traveling in South America and presently in Equador. Gas is cheap here. 2.20 per gallon of 92 octane. However if you use 1 liter of oil at $6-7.00 for every fill up like I have to it is no longer cheap.

I am looking for a fix. Its either the rings, the valve stem oil seals or both.

As all you gen 1 owners know, the rings are no longer available for this bike. What rings or piston and ring kit does anyone recommend for this bike and what is it likely to be that is causing it to use so much oil. I am told that it might be broken sections between the rings on the piston and unlikely to be the valve oil seals.

Also does anyone know a good place in Ecuador where I can do the work. Someone that can help me maybe

Thanks guys
Nick

Saw a thread recently (will try to find it) where a guy from somewhere in SA said it was common thereabouts to use a Honda (IIRC) piston and rings. Same diameter, but slightly shorter, which lowered compression only slightly, but cleared the valves anyhow. He said these pistons were used in KLRs because they were readily available, and relatively cheap, compared to OEM stuff.

Search the forums; maybe you will find it before I do.

Edit: it's the Honda Dominator NX650 piston...check your thread in the "other" forum...there's a reply there that covers it.

Good luck!

You might also be able to find a supplier who offers rings by dimensions. We used to source rings this way for all sorts of things but those businesses have apparently gone away in Canada because of not enough volume. We often bought rings which were a bit wider and recut the ring grooves to deal with worn piston ring grooves. Those were different times but you may find some of this going on in less developed countries because labor costs are lower compared with parts costs. That's what used to drive these options in Canada.

I should get off my butt and do some looking as it might help someone.

Another aspect is excessive piston clearance, especially if the cylinder needs true-honing to clean up too much taper or out of round. We used to knurl the piston skirt to expand the piston, then re-fit the piston. There were varying views as to clearances and whether it was better to put one together very tight with the knurl as rolled in or to draw file to specified clearance. I've done it both ways and found both to work well. One does need to watch temperature during initial break-in if fitting a tight knurl.

I might do my own that way here but not likely someone else' bike. These may be decent options down your way.

Question: Do you have the piston out of the engine? If so, how much taper & out of round? Piston clearance?

Do the rings look good? i.e. No scoring or chrome peeling, chipping from the oil rings, that sort of thing? If end gaps are within specs and other condition looks decent, it may be worth simply deglazing the cylinder and doing a hard break-in. I did one last year like that and oil consumption went down to normal. Apparently it was babied or otherwise lost ring fit. Just a thought as it would only take a head gasket and some time to find out. Assuming condition is decent.

Interesting option, Clogan, thanks! I wonder if a high compression piston is available for the NX650 which might do?

You were responding to help out a fellow traveller. Being a business or individual doesn't make a difference to us from a Moderation stand point. It would appear differently if you started the thread. It's all good and hope you can get Nick's issues solved.
