Just installed some new shock bearings & rear wheel bearings and a heavier rear shock spring on the yz250... set my race sag at 100mm but there is next to no static sag obviously the spring is not as heavy as it needs to be... however the bike was running 6" of sag previously (had know idea it was that easy to set) so it should be a godsend even if my ass cops a flogging

Can some1 help I run my 125 at 32:1(625ml of oil to 20L pet.) I used motul 100% synthetic 2t 800 oil and it doesn't seem to be as smokey as normal. Has anybody had this problem b4?

I just built a cr500af ! If anyone wants to buy a afcr500 frame with mounts fitted, just need to fit ur motor ! ! Pm me

One for you 2 smoke boys Fuel injected CR500 !!! http://www.youtube.com/watch?v=TE5ENcMH1ZI

and another http://www.youtube.com/watch?v=Y91Jm...ature=youtu.be (http://www.youtube.com/watch?v=Y91Jms6MyCY&feature=youtu.be)

that thing is an animal....Good to see someone is finally tackling 2 stroke injection on a dirt bike. Even better that it's 500.

What mix ratios do you guys run? I've got a YZ 125, and we run it at 65:1 with a fully standard expansion chamber and muffler. Have had no dramas with it in the 2 years I've had it

cant beat the sound of a 2 stroke 500cc at idle ting ting tinngta ting,and then wrapping it on whilst hanging on for grim death,i ride a 04 yz250 and rode a mates 3 day old rm450 and i gave it back to him extremely disapointed

I had a yz250 pretty sure my mix ration was 30-1 ---------- Post added 20-01-13 at 10:28 ---------- There's no way I'd run 65-1 not enough oil

Its as lean as I'd go, but its not a harmful ratio. You will seize however if u run aftermarket pipes or a modified engine, mine still dumps oil out of the powervalve drain hose after a ride. Basically, a 2 stroke will use the same amount of oil for lubrication whether you run 30:1 or 65:1, so if you run say 30:1, your engine will take in a certain amount of oil and then burn a heap that's left over. So running less oil to a point means that the motor will just burn a little less excess oil, not lack lubrication.

mixtures obviously depend on what the bike has been tuned to run. My RM250 was 32:1 and my current bike is 40:1 ...... obviously if you are doing WFO riding then then more oil for lubrication is the go. Woods riders can quite often run up around 60:1 as they aren't at peak revs constantly. I'd run what you feel comfortable with and tune it accordingly.

2 strokes r more fun and cheaper to rebuild than 4 strokes every 4 stroke I c in a bike shop is getting valves done the new 4 strokes r **** boxes

I rode their FE450 and the power delivery is so smooth and easy to control, plus it felt like it pulled forever. I'm a fairly average rider and I could power slide the thing around corners with both feet on the pegs and it would never feel unstable. 4 strokes definitely inspire confidence. Keep up the preventative maintenance like valve shims etc and they can go forever.
