Recommended break-in procedure and fuel ratio
Did a search and nothing turned up.
What is the recommended break-in procedure for a fresh top-end on a KDX 200? Would 40:1 motul 800 work ok?

The heat cycle method is:
Start bike and run it until cylinder feels warm.
Shut it down and let it completely cool

You get the idea.

basically just dont overrev/overwork/overheat the engine at the start. you need to warm it up then go for a 15mins ride, let it cool down and repeat this for 3 times and you are ready to full bore the bike.
I will just use normal fully syntheic 2T oil. motul800 seems thick.
you can find a detail running in procedure from justkdx.com

My recipe, FWIW...
First tank was Dino oil, warmed up 10 minutes at varying rpms nothing crazy just little blips here and there. Rads warm to hot.
Went for a 10 minute ride on the streets getting on the pipe only slightly. Put it away for the night.
Took it to the trails, 10 minute warm up routine. Then RODE IT LIKE I STOLE IT.
So about 30 minutes of babying and full on after that. Kind of a hybrid approach to the break-in methods.
Synthetic oil there on out.

That is what I usually do. It won't want to rev out cleanly at first, I guess because the motor is too tight or the rings aren't sealed in or something. I'll bump against that "rev limiter" a bit here and there. After 15 minutes or so it'll clean up and go like stink.I bet you could just start it, warm it up, and then ride like normal and it would be fine.
I guess I use the " rode it like you stole it" aproach

The rings would never seat if you did that...Ipaman wrote:I bet you could just start it, warm it up, and then ride like normal and it would be fine.

These engines actually have to 'break-in' as there are no rings and the aluminum piston-brass sleeve is a matched set just tight enought to move, and loose enough that it will 'break-in.' Break in on a modern, accurately clearanced, precision motor is simply ring-seat. Nothing needs to break in except the rings. I 2nd inda on the ride it like you stole it...It's been proven too many times to provide superior ring-seal, compression(power), and longevity...key in the process is that the rings must be under load to seat the best possible way. I also 2nd the use of non-synthetic during break-in as the synth prevents wear IE increases time for rings to seat. Inda is right you can feel it....When they seat, you are done....Howver I'll keep riding until my 1/2gal-1gal of break-in gas I used starts to run out. Ride it hard, and also vary RPM range motor is getting flogged.I learned it form my RC cars.

Interesting. Any recommendations on what pre-mix oil and ratio to use during and after break-in?fuzzy wrote:These engines actually have to 'break-in' as there are no rings and the aluminum piston-brass sleeve is a matched set just tight enought to move, and loose enough that it will 'break-in.'
