Is it really that much cheaper?
Best thing about this is you have a whole extra motor when you're done, right?
Well, what about Pieces/partsing something together that would be the equal or surpass this build.
I've been compiling some parts lists Let's see if I forgot anything. Also using retail pricing.
124ci
SE Pro Crankcase assembly ................ $600
S&S 4.625" crank from Darkhorse ......... $1600
H-Beam Connecting Rods ................... $550

Assembly by a competent engine builder .. $1500 (rough guess)
Dyno Tune ................................ $300
Total in the bike and running ................. $8900
Contrast this with the SE120R
SE120R Motor ............................ $5500
Throttle Body ............................ $450
Intake Manifold ........................... $90
High Flow Fuel Injectors ................. $140
Total Parts ................................... $6180 (Only a thousand different!)
Installation into Chassis ................ $500
Dyno Tune ................................ $300
Total ......................................... $6980
You save on labor with the SE120R, so ~$2000 cheaper. But it won't be put together as tightly. Likely won't be as reliable or make as much power as the full build. And both scenarios leave you with a full extra motor to sell on ebay
So is the SE120R really such a deal? Am I forgetting something in my calculations?
