I guess I look at this way. At least greg(jaws) has a heat shield. It does it's job keeping that pipe hot to get the hp/tq we want. No one other company offers a heat sheild?
I remove enough material to get 0.83:1 ratio ( max overdrive)
It's not just about that. It's straightening, machining so no binding and smooth operation
My opinion
They want a 1:1 ratio mostly and for any over drive, that becomes a liability.
Ive had belts flip from machining to much overdrive. That's the liability I'm talking about .
1:1 is good enough for Polaris.
For us , no, never enough, lol
That's depends on a lot of things.
Like you're weight, lug height, gear ratio, suspension set up, clutching in spec
But usually , a 50/44 fp or 48/44 fp is a safe bet for trail riding in most cases. A 48/42 fp is more conservative for heavier riders and taller lug heights
Me haulin and doc talked about the driver change and hacksaw a couple/few years back. Timing systems don't lie. I just won't switch out the cobra as I like it to much.
Flatter, no bowing in track under load, etc...
The places you ride. We go there too. :D
For you're lug height and were you ride and how you ride . Get the Dalton or cpc set screw adjustable weights. Nothing better for ease of adjustment. Also, ditch the tss-04 secondary and get a P2 or tied. Way way better for upshift and backshift.
Docs sled and set up works very well as I drove it . It's all about rolling resistance, friction and weight. 3 key factors to get you ahead of the next guy by huge lengths .
The only thing I won't change, or haulin-the-mail,Is the cobra to the hacksaw.We'll sacrifice some rolling resistance...
It's a gearing/driver calculator
Left is 1.74 ratio with 9 tooth
Right is a 1.95 ratio with 10 tooth
