Message Making more parts.

This is the coupler to connect the R1 motors output shaft to the jackshaft carrying the drive sprocket.

This is the housing that holds the bearings supporting the driven shaft/flywheel.

Modified R1 output shaft with flange to mount flywheel.

Chromoly flywheel after facing.

Machining step for friction surface.

The bearing housing/driven shaft/flywheel/clutch.

Chain to housing clearance.

The housing has a counterbore to hold a 47mm OD bearing and a 62mm OD bearing. There is a sleeve between the two bearings so that the thrust load (from disengaging the clutch) is shared by both bearings.

R1 output shaft coupler.

When I welded the sprocket to the coupler the splines shrunk and the sprocket would not fit the R1 output shaft. I machined the splines away and machined a counterbore for the second sprocket to center in and bolted two together to complete the coupler.

24 tooth sprocket welded to flange welded to splined shaft out of '04 R1 gearbox. This shaft will be shortened on both ends.

The coupler will be welded on this end.

This is a rough orientation of these parts.

R1 engine fully mounted in the frame.

Removable upper brace/engine mounts.

Coupler in place.

Location of bearing housing.

The 24 tooth sprocket (not pictured) will drive the 14 tooth driven sprocket for a 1.714:1 ratio. This will provide a geared top speed of 172 mph though there is currently not sufficient power to push through the drag created by the roadcourse aero package. By changing the gear selection in the R1 gearbox the overall gearing can be adjusted to suit different driving situations.

The right side tie-rod was bent so I set to work making a replacement.

After I cut the ends off.

I was unable to locate replacement ends for the tie-rod so I machined the old parts away from the tubing.

New tie-rod.
