    I got the bike for 700 dollars and it's fine for a play bike rlly strong I need to know how much oil to mix I've heard 4 oz to 1 gal but i don't know and it dosent want to ride a wheelie so is it I'm running the wrong sprocket size I'm running a 51 now and I have a dent in the header pipe and it has been welded so how would I get that out I've heard of freezing it but it can crack the pipe so yea but I don't wanna heat it and it explode so what do I do?
    If u could leave a comment or whatever it's called thanks have a nice day
  • I'm not a two stroke guy but most of those older bikes ran around a 30:1 ratio I think, some of the newer ktm's run 50:1, I think it depends on the oil too.  As far as the gearing goes I run 13/50 on my 250F and I have to pull pretty hard to bring 'er up in 4th, I'd think 13/52 would be good gearing for a 125 smoker, and the dent in the pipe is easily fixed with a spot welder and a dent puller with some heat applied to the pipe so it doesn't crack when you use the dent puller ( the pipe won't explode, you can take it off the bike if you want)

    Thanks
  • Run a 32:1 or 40:1 mix those are the best and most common mixes, as for the wheelie i dont think its the bikes gearing or mixture you just need to get used to the bike and find the balance point.
