if it's "jetted right on", it shouldn't be smoking a lot.
there is a seal on the KIPS shaft...part number 92049-1238, and if it's worn/leaking, then it will show a little more black oil than normal when you pull the cover.

you could have a bad clutch side crank seal too...which would allow it to suck tranny fluid and burn it, causing the excessive smoking...a possibility.
and if it does have a bad crank seal, you'll never get it jetted correctly.

There is a lot of oil. It poured out when I pulled the cover. I have been lucky not to pull the cases apart but I think its time to just do it.]

yup...then you'll know what you have, and can start fresh with a tight motor.

When I pulled the exhaust valve cover this is what poured out... Not good! 


Ive been putting off splitting the cases so I decided it was time to replace the bearings and seals through out the engine so I know it would be nice and tight.

Motor pulled, trying to decide if I want to powder coat the frame while she's apart.


Motor pulled and it begins..

Pulled the cover off and they had no gasket, so there is a little bit of a mess I need to clean up.

The cases are looking pretty rough on the outside.  I planned to send these to member sandblaster to have these done but unexpected expenses causes me to save that till another time.

So I have been working on these with scotch brite and some elbow grease.  My fingers are sore!

Has anyone had experience with power coating their frame?  How lone does it last and is it durable?

I have always repainted with color rite paint and it of course doesnt last to long.  I am debating going with the green frame as I was never a big fan of the gray frame that came on this originally.

Looks like that will be the next project on this bike maybe for the winter.  Time to get it all back together and ride for now!

Im pretty happy with it, lots of hours of that manual labor...  I had picked up a few add ons as you can see that made it look better than stock.  I am just waiting on a couple motor mount bolts that needed replaced and she will be back in action! :-D

I have searched for this all over but cant find the offset for the triple clamps on my 2004 KX 125.  Does anyone know where I can find this or know what it is?
