EBR(LAP) lists a big bore kit (with or without exhaust) I assume this is the kit for the 1125? Part number 1190.13AZ Big bore kit 106mm. Can anyone confirm this is the right number? | ||

yes that is the correct part number. I bought a kit in February. They just removed the ECM and exhaust from the complete kit to make my order. Shipping was $28 to Ohio. | ||

@Mrlogix Thanks, I appreciate the info. I assume with the pipe and ecm the tune is plug and play? | ||

@Mrlogix Very cool, something to think about. Are you building yours yourself? I assume good rotax mechanic/tuners are a somewhat rare commodity? I know Ski doo used rotax motors in their sleds for years. So maybe a good Ski doo mechanic would work. I guess the big bore kit is a somewhat standard build besides the particulars of that specific motor. But I assume the tuning would take some expertise. | ||

Yes, I will be doing the building myself. I bought a used motor (08' CR) and plan on doing all the build on it and keep my original motor in case I decide to part with the bike. My bike already has the EBR race tune and Dean Adams full exhaust. I am hoping that it will be sufficient point to start with. I am going to try to tune it myself just to get it running and then take it to a dyno shop for the fine tuning. | ||

Cool, make sure you post some pics. I for one would love to see the progress and results. (Message edited by Zhen13 on April 28, 2016) | ||

How difficult can it be? Pull the heads, jugs, pistons. Reassemble per manual, torque to spec. Ride the shit out of it 😊 | ||

The big bore kit makes a nice different in the torque. It increases across the power band which makes a big difference seat of the pants. With the EBR exhaust and a big bore lots of guys were seeing upper 140's for hp at the rear wheel on pump gas. |
