quick primary spring question for m8

[sonmtn]

Putting a new clutch on my 2007 M8 running 68 weights (6000-9000 ft) and was wondering if the stock yellow/white spring is fine or if there may be a better choice and why you like it if so. Thanks

That spring is OK. I like the Speedwerx 125/340 for that sled.

real close to the same engagement is see but is there a notable diff on the top end?
And also what is the take on titanium vs. regular?

titanium is better but more expensive. I like the yellow/white my sled rips with it and pulls 70 gram weights up high with a speedwerx pipe.
