Load it up!! it will pull it. You will be surprised!!
BC.
a stock tune won’t pull a 73g dalton dtya profile. Not even close.
I’m running 8LR00 weights loaded up to 73G on a stock sidewinder with Cr straight pipe last season. Worked awesome . Pretty much bang on 8750 rpm climbing in deep snow.
Secondary spring setting at 3-3 60 degrees
I have not used the daltons. Just thought I would put my input in with the 8LR00 weights. But makes sense.
I have the stock MTX weights loaded with heavy rivets now, will just wait for my 8LR to get here, it seems to be a proven combo with stock tune. I will be trying the Dalton black/orange secondary spring, probably start at 3-3. My sled was a belt eater last year, so over summer ended up machining 3mm off secondary to get it to Yamaha specs, also kept flat spotting secondary rollers so put a billet helix (OEM angle) in so now at least all three are contacting(at rest anyhow). Will see how it goes. Riding around 6500’
