I couldn't get it dialed with the mag weights so I put my mds adjustable weights in @ 77 grams and it's a lot better..I usually ride around 7-8k feet. Let me know how you guys set up your clutching and let me know how it runs I was told to set up the mag weights 1-2-2-1 from heal to toe, it ran really good if I pinned it after 5000 rpm but out of the hole it would just fall on its face. I premixed the first tank and I thought maybe it was just running super rich so I drained that gas, changed the plugs and put fresh gas (2.5 gallons of 110 the rest 91 non ethanol and it still wasn't running good on the bottom but last night I put my mds weights in and it ran really good. I think it could still be a little better we'll see how it goes.
