Hey guys just adding a little about the Transmission myth of the 120HP DSSC system since at this moment I'm having mine worked on. I recently (July '16) had my engine worked on had heads done, cam work, jugs, carb, whole top end built from scratch and all. My dyno run was 122HP and 134ft-lbs torque, at work now so no paperwork to prove that but that's what it was. But in Feb '17 after only about 1000 miles on new motor mods my front head went. Sent the motor to S&S Cycles to determine the root cause of failure. Come to find out workmanship. And of course the damage to motor is so bad they would rebuild it, but it would be cheaper to buy a new motor. So, I ended up buying a S&S V124, which comes with 128hp and I'm thinking 138ft-lbs torque. Well I seen the post by Curtis about the DSSC system. I contacted him and he confirmed the motor is to much for the trans, but said he is working on a fix for the problem but it may be a while. He suggested going to the new main shaft design and using the hardened shim, nut and washer. So, I called Baker and asked what can I do about beefing up the trans and the guy agreed with Curtis on the things he said to do, but the guy from Baker said the only issue you'd have after the trans mods would be my clutch assembly, because they too will not handle that HP. So, now I'm having to also install the Baker 2.4 Belt drive system. And with all the trans mods, baker belt primary that will make my trans good up to 130 HP. So the Baker guy has said I'll be walking a thin line depending on how I ride. So, guys with beefed up motors if your bike is older than '07 cause mine is an 06, and you've not went to the new shaft design, using the hardened shim, washer and nut to hold the clutch basket on your main shaft, your trans will eventually breakdown.
