M8 Stage 1 Jumping to Stage 3
#11
Thanks Oz. I understand what you mean now. Last question I have is, is there no more distinction of torque-or-power improvement in stage 3 anymore, like in stage 2? Since in the description it states that both power and torque get improved. I am wondering if the distinction (power vs torque kit) is only relevant in stage 2.

Thanks again Oz and everyone else who answered. Oz, I appreciate you sharing your knowledge and clarifications. I am more confident in how I want to proceed before this thread because of you.

You are welcome brother......can’t recommend enough though to get the dealer to put in the new 8 lobe pump.....I’ve done mine. The kit for the pump is part number 6240024.....

You are right on, Stage 2 offers two different cams as stage 3 comes with I believe tha 498 only. and agree. If yours id 2017 road king have them change oil pump. Tech center im Milwaukee did my stage 3 and left original oil pump. Had dealer change cam this summer and lucky for me they noticed it and no labor charge since they were already in there.

You can have the torque cam installed with a stage 3, a few had it done and have posted on here...

My question would be "why?" I had both the 107->114 stage 3 and a stock 114 bike with the S2 torque cam and the stage 3 made both more HP and torque then the 114S2 bike did, by a substantial margin. The S3 kit includes heavier valve springs to account for the higher lift of the S3 cam. Doesn't make sense to me why one would do that. Do you remember the logic behind why that was done?
