KTM 690 Engine Overall (Any Thoughts???)
« on: February 05, 2015, 07:36:22 pm »
Hi Dogs,

Any of you had to redo the motor on a 690 yet, you know con and big end that kind of thing?
I have a few questions for you.

If so around what mileage did you do it on and what condition did you find the motor in when opened up?
At what mileage would you suggest opening it?  Assuming you did opened it and found a bit of a surprise on how bad it had actually worn?
Which parts did you find the most worn and what do you think the costs would be to overall the motor?

I just want to prepare myself for what is inevitably going to happen, a bit of insight as to what's in-store could save me a few surprises along the way.

Thanks,

Just done a rebuild , piston started breaking at the edges , but the whole job was about R18k , absolutely nothing aftermarket available .
The 2012 and later are more reliable although I suspect the particular bike I did was more down to owner abuse , I have rebuilt 2 other engines for him in the not too distant past .

What mileage can be expected before a 690 needs its motor opened and looked at?

The motors wear well, its mainly component failures that will cause a rebuilt.  I know of an 08 that has done 110 000km.  Other than pathetic electrics, the main mechanical issue is rocker arms, but they are only about R600 each.

I have come across quite a few mechanical failures , but all different things and all on the 08/09 models , no specific item that is know to fail , some have had less than 10 000km , but most have decent mileage with no problems .

Thanks for the reply, what mileage was the bike on and also what year model?
What was worst off, the chipped piston? If something has to be replaced first what would you start with? To improve the life of the motor?

What happened to the chipped off piece of piston?

The bike was a 2011 with 12 500km , the piston had unusual damage , the top ring was missing , my thought is that the engine had been opened before and they had broken the ring so removed it altogether . This weakened the top of the piston to the extent that the edges started collapsing .
Preventative maintenance is pretty basic , service at recommended intervals , use a good oil , and get the bike warm enough before riding hard , no rocket science just common sense .
