I was searching more info on my '06 RCM 125sx Zongshen engine. I came across this site that has a warning not to use 100% synthetic oil in the Zongshen. Anyone know this to be an issue? I just made my first oil change with Motul 100% Synth. No big deal to swap it out but I was wondering if anyone can give reason to this.

You saying the 100% synth oils are not good for the clutch? I know moly-b based oils are bad for and clutch but synthetics?

Amsoil guys claim that it will not hurt wet clutches and it seems to be fine in anything I have tried (100s of bikes and quads by now)

i run full synth in my cbr600rr and all my dirtbikes.....no problems and they seem to run much much smoother

clutch slppage would be the only possible issue, but would this engine really slip it? No trouble with my RC51 (130RWHP) and full synthetic AmsOil.

OK, with zero experience on the subject, I have spoken out of my arse! My pit of a bike has been slipping without using synthetic, I've been reading here in PM that I should upgrade the clutch springs, which I'm ordering soon from Dratv.

mototroy · 03-04-2006, 06:15 AM

I think I've heard enough. I'll leave it in and run it.

Thanks for the input.

Most moto oils have synthetic aditives designed in them to minimize clutch wear, I ve use synthetic in a gsxr6 one time and ended up with virtualy no second gear, I ll never use pure syn again in a bike.

dirtracers warning would be enough for me.

It never occurred to you that there might have been a problem with it before the synthetic? Hundreds of thousands of motorcyclists use full synthetic and almost all racers use full authentic. Now do you think they would compromise a win for a DNF? I don't think so!
As for your shifting problem, you need to check the Suzuki recall list. On some model years 2000-2002 I think, they used an inadequate shift shaft that was hollow and they were having severe tranny failure. The parts are warranted by your dealer and repaired free of charge. I am not positive of the exact years of the problem but I have done the replacements myself.

I believe the warning is based on gearbox action. It seems some mini-motors shift smoother on dino-squeezings compared to full synth?

That's funny you would say that I was running Castrol dino for break-in on my XR80 and recently switched to full synthetic and it's harder to do clutchless shifts now may go back to dino-oil and see if it get's better. All my big bikes shift better with synthetic? Weird.

mark said not to use synthetic oil with the four speed knock off trannys becuase from 4th to 3rd it catches a flase nutrel

I have only use synthetic on my big bikes all of them my gsxr1000, my 636r and my old gsxr1100. never had a problem!!

after my 110cc locin was broken-in and has had sometime of use.. I switch to synthetic.. and the trans is smoother engine runs like a champ. my other 125 gpxs are not fully broken in but I will most likely use synthetic in them too.

thorwarrior915 · 03-06-2006, 11:14 AM

I always use non-synthetic to break in an engine, like everybody else. I have never noticed a difference switching back between synthetic and "dino" oils. I think some of you guys are tricking yourself into believing that your bike acts differently with different oils. I run usually a super cheap non-synthetic oil during break-ins that behaves the same as the synthetic amsoil that i usually run.
