The 14 and later Rushmore come with cams very similar to the SE255.

The 259 needs about 10.5:1 compression to keep from having a soft bottom end. IMO, I wouldn't stick them in a stock engine without bumping the compression.
What about the poor fuel, i jus rebuilt the carbs on a ninja and let it set and yep they're fouled again, piss poor gas.
I figured a good compression on a hawg at 9 to 1 or 9.5 to 1 maybe, with cnc head porting stainless valves roller tip rockers adj pushrods, solid lifters, and a cam to match, oh and a bore job, maybe make a 88 inchers pull a trike, ? maybe, ? jus one Ive got on the table eyeballing, (93flhtc) I still think a v rod would be great, (kill the heat) too bad no lower end, that and the mid range is where i live. best to ya.View attachment 30616
1969 Harley police motor, yep original numbers.`This my trike i built in 1975 4 time show winner with a different paint job, and a hand made box from ash paneling by a cabinet maker, my neighbor, at that time.
Roller rockers are only needed when you get into the .600 and larger lift cams, most of the bolt in cams people use don't need them.
Sharp looking trike you have there.
I have a 2011 trike with the 259e cams. But you need to bump your compression to 10-1. I also have the stage 4 kit minus the bigger throttle body. They didn't offer that in 2011. I have the SE ported and polished heads. V&H Power Dualls and High Output Mufflers. Do not put stock lifters in with this set up. They left the stock ones in when they built the motor and it trashed the lifters , rear cam and oil pump. So what did the idiots do, put in stock lifters again. Same thing happened again. I took it to and Indepentent that used to own this dealership and he rebuilt it with S&S bottom end,bored the jugs 5 over, put Competion cam lifters in and SE oil pump again with a special relief valve in the pump and now at idle it runs about 15-20lbs of oil pressure. No problems with the motor now. I have 100hp and 108lbs torq.
