Not going to offend me. Customer bought the kit and brought it to me. I had him take back the SE tuner because he already had the same tuner locked to his bike. I had him return the lifters and pushrods. He originally had the 259e and after a quick conversation about his riding style I suggested he trade the cam for the SE 585. Not my cam of choice and this is the first I have tuned, but of the 2 cams that were the option. This one suites him better. This is based on comparing the 585 to the 555tqster and the TW57. As for as the top end HP. What is the limit of stock CVO heads, what's the limit of the 585 cam, and what about the limit of the stock ventilator AC for the SE58? I think that AC would be much better if they would of designed it to suck air from the front of it also.
Glad we can talk freely, some on here are easily offended and then you have to go underground on PMs.
The SE-585 has a nice and low overlap number, but it also has a relatively short intake duration compared to the SE-259E. I understand the customer’s constraints though when you’re trading parts. I cringe at the missed opportunity to change a $32.71 0.030” thick head gasket and get another ~0.2:1 compression. 9.9.1 --> 10.1:1 with stock heads. You’re probably right about being near the max flow of stock CVO heads with an 117ci. The stock ventilator AC cannot be helping either, but it is what is.
There are several head porters that might chime in on the max flow capabilities with stock CVO heads.
Thanks,
