I was referring to the direction of this thread (Bees and their concept of time??!!)\, but that turn sounds like fun too. :lol:

haha, I thought it was the thread direction too...also went back to watch the turn in the video and still got wow'd
Found this, seems to be a decent deal?

Seems pricey, but a very nicely turned out bike. Could be worth it if you want that particular setup. Would cost more to recreate.
Offer $3000?
Sweet motorbike. I agree w/ the price. Although clean-ness and the choice add-ons may make it worth it.
Wasn't there a new frame in '12? Maybe hurt the value a bit?
He says 1-year only because it is 6-speed, PDS and a close ratio XC? Was that not a normal combo any other year?
FWIW my 200 is a XC-W converted to XC.. so also PDS, also 6-speed, also XC and I love the damned thing!
Just increasing my post count. Feel free to ignore me.

might as well put this up here and the chainsaw thread.

Took my new-to-me KDX220 out today for my first ever dirt ride. Went surprisingly well, no crashes, only a couple tip-overs.
Previous owner didn't own it long, but he said he ran 32:1, so that's what I ran. Seemed to run great, lots of power, lots of smoke.
Sure wouldn't mind a magic button though.
Total noob to 2-strokes here.
Is there any harm in me switching to 40:1 or maybe 36:1? I've read other KDX riders run 40:1 or even 50:1.
If it's jetted for 32:1, would changing it affect anything? Does ratio even make a difference for jetting?
With trials around here being very technical and me being super slow, would a lighter oil ratio reduce the risk of fouling a plug?
who the F knows :spit:

get a lectron!
Going from 32:1 to say, 40:1 is going to effectively richen the jetting. If you're running good oil, not Wally World discount weed eater premix and desert topping, I don't see a big risk other than possibly fouling a plug from the additional fuel, maybe.
for reducing smoke, try the various smokeless oils and see if any offer improvement.
On my YZ250X, the manual says run it at 32:1, I ran yamalube synthetic at the recommended ratio for the first 5 gallons. It smoked like a pig, felt boggy, and I fouled 2 plugs. I switched to Motorex synthetic and went to 50:1 ratio and couldn’t believe the difference. Crisp throttle, very little smoke, little to no goop out the exhaust pipe, and no more fouled plugs.
I run Maxima synthetic oil @ 50:1 and jet by the book in my KTM 200 and am delighted at how it runs.
I have never experienced a fouled plug. I always thought the plugs fouled from oil, not "additional fuel". But as I say, no experience there. I believe my toolkit has a plug in it per advice from when I put it together. But its never been used.
Interesting topic. I just mixed up some fuel for my '07 CR125 this weekend. I have a gallon of Blendzall Gold Label that I wanted to use up. The recommended ratio is *16 ounces* per gallon. That is 8:1.
We will see how she runs...
So, after a lot of testing on 125GP racebikes, they found that power is best at a pretty high ratio of oil. I can't remember the exact number but I want to say it was like 15:1. I'm not smart enough to understand the reasons why. I always ran 30:1 in my GP bike as per Honda's guidelines, and 50:1 in my KTM as per their guidelines. Less oil=less smoke and generally cleaner running. If I still ran a 2T dirtbike, I'd run 50:1 with the least smoky oil I could find a la R7s suggestion.
More oil is basically liquid dynamic compression ratio booster / ring leak down remover. Those 125GP machines are single ring screamers having to run larger ring gaps and piston to bore clearances because of the RPMs and thermal loads they're putting on them. More oil helps seal'em up. Also, back when that test was done, premix oils were of a VERY different composition then they are now. I'd love to see the test repeated on a modern MXer or woods two stroke with a two ring piston setup and a power to weight ratio that isn't squeezed to GP levels with modern oils.
50:1 on my 2006 ktm 300. I think it calls for 40:1 up to 60:1. Runs great at 50. Haven't bothered experimenting. No sploog out the exhaust.
If you could have an rpm data logger on a 125GP bike and a 125MX bike I bet the GP bike would have more periods of sustained full throttle?? Never been on a 125GP bike but in MX you will have shorter straights (for the most part), varying rpm as the rear wheel leaves the ground for jumps or whoops, and rpm robbing sand or loamy soil(track depending). Could that cause the GP bike to run 15:1 vs an mx bike at 32:1, 40:1, etc? Also on the GP bike you have a finger on the clutch to save you if the engine seizes while on the MX/dirt bike you have a finger on the clutch to fan it and get the rpm backup. Basically saying the 2 engines are "run" differently and therefore the oil ratios are different. Of course I haven't touched on brand of oil, jetting for temp/altitude/oil, and the oils available then vs now. In the 80's many of us in the NE ran spectro in everything from 80's to 500 cc one bottle to 5 gal of gas. I think that's about 50:1.
