RX timing is screwed most of the time. My RX100 is bone stock no modifications were done anywhere it rolled off in 1992 so it's not one of the 6v to 12v cases. The motor was rebuilt this February ran the damn thing in just fine, been using excellent quality 2t oil. I did a WOT run recently the damn thing did not want to cross 80kmph came back home only to be greeted my old friend piston slap lol I am dead sure the clearances were set right because I read the numbers from the workshop manual and made the machine shop guy run those numbers down for me. With this grime in the back of my head I posted my query on what I like to call one of the best automotive forums on the internets, yes the RDD. Anyways for the doubters and haters ima post a bunch of clips I just got down from my phone let the marks speak for themselves but guys put your RXs under a timing light and if there are any problems dial your timing in because screwed up timing WILL trash your motor in no time.

a 2 stroke should never kick back my RX kicks back like a bullet would that's the first sign of wrong advance at idle. Need to work up a good number coz if I go crazy with the retard part I'll loose the low-mid end grunt but that should give me a good top, at least that's what theory says. As of now the top end is totally crap and need to sort out the jetting part as well OH! So much to do so little time!
Just marked the idle and max advance on the rotor started her up 2 observations, and I can tell you everything that Ron says about stock timing is nothing but the truth, anyways without further digression they are:
