How should I run in my rebuilt KX500 ?
dangerous dean:
dont run synthetic? im sorry i have never heard of that one before????? to be honest i wouldnt take the chance of having any of the old crappy non-synthetic oil hanging around in my engines...mainly because the 2 dont mix and you will end up seizing something, i might be totally wrong but really i have never heard of that...maybe higher beings can enlighten to why?
kaw rider:
I had a fresh plate job not seat the rings because of it. And i have used this plater for a long time and this time i was in a rush and used synethic and had only 60 ibs compression. Had the plater look at the cylinder and install new rings on non-synethic oil on pump gas on had 210ibs compression.
I think on a used cylinder or a plated cylinder thats has some hours on it, it's not a issue.
race gas and some oils have additives that glaze over the rings.
kaw rider:
This is what my plater recommends.
What kind of oil should I use?
For 4-Stroke engines we recommend high quality petroleum based motorcycle oil. Many of the non-synthetic OEM engine oils work well and allow the rings to seat quickly. Do not use full synthetic or semi-synthetic oils for break in they are too slippery and keep the rings from seating on the bore. For 2-Stroke engines we recommend Yamalube R mixed at 32:1, we have no confidence in wild 50:1 or 80:1 claims by oil manufacturers. Oil is cheap and piston and cranks are not.
dangerous dean:
sorry still not convinced, why do manufacturers recommend using the same oil as they come out of the factory? i had a orange 300 and that baby only ever run on synthetic from new and as for 150psi difference in compression from non-synthetic to synthetic mmmmm was there a ring missing or the head not torqued...

My 2002 KTM new came with petrolium based oil.... in the manual it straight out said to use petrolium base for the first oil change also.... from then on... full boat syn.... KTM engeneers know more than me... so ....
