Break in?
« on: December 04, 2003, 04:11:32 AM »
I was wondering the best way to break in the 500. On my 250, I would do a 5 min warm up and complete cool down. Another warm up with light ride(no wide open rips). Another light ride and that would be it. Never had any problems. The shop I bought the 500 from recommended light riding nothing over 3/4 throttle for two tanks of gas.
I know not to run a synthetic pre mix during break in, I have always used Yamalube during break in(but is a semi syn.) What pre mix are you guys using during break in?

Yes, What IS the best/proper way to beat in a 500? All the manual says is to "Avoid full throttle starts and rapid acceleration". Any one with any info?

20 min ride, cool til the cylinder feels cool, 20 min ride, cool again, run it easy for 2 more gallons, then punch it...!!  Easy throttle, not too low, not too high during break in.  Dont short shift, and dont stay at one RPM very log - up and down the RPM range smooth and easy....Dont be timid, just dont make it pull too hard or too high...

I use Golden Spectro at 50:1 - never had a problem in 20 years so I'm afraid to switch...

Question!...
Why should you not use fully synthetic pre-mix when breaking in a new motor?? I got a '04 that hasn't been broken in yet and I've already bought some Royal Purple TCW 3 pre mix for it.

^ not enough friction to break in the rings properly.

Interresting point! I always break in my 2-stroke engines using the same synthetic Belray I normally use with no problems.....however, I just broke in a new motor in my truck and specifically used non-synthetic oil so the rings would seat.  I never considered this for a 2-stroke. I wonder what is best??  Cam.

I just gave it some thought.  I think the difference might be the amount of fuel wash on the cylinder walls (more prevents glazing during breakin).  A 2-stroke ought to have lots. Cam.

So, what you're all saying is to not use synthetic mix but, rather use the good ol' cheap stuff for the first couple rides. I really don't want to screw my new motor!!!

I would use regular oil for break-in. That is the industry standard. :)

Since I've ever had a two stroke, I've broken them in with synthetic. I've never had a seziure so far, except fort a rod bearing falling apart after six years of service. I broke my K5 in with Klotz SuperTech without problems. Maybe luck, I've never heard of not using synthetic, as I've used it for years. News to me. :-)

I have to agree with Gowen.  I have broken in bikes with regular 32:1 mineral oil and with my usual Belray 60:1 synthetic, and in both cases broken them down later.  I'll stick with the synthetic.  With mineral oil, I recall the occasional mild seizure on a high spot; tear it down to poilish it up.  Never happens with synthetic. Cam.

Gabe, how are the bones healing?

Slowly  :(

But I'm enjoying the time to fix up the bikes and make sure they are all ready for the go day. BTW, got a KX green cast.  8)
