No. Cent. clutch with a jack shaft thru the bottom bracket. I rebuilt this 72 B&S 5hp engine but am looking for a reasonably priced IC 5hp to build for this bike. I removed the Gov. on this motor so I can use a Mikuni 22mm carb. Should move along nicely at around 40mph. Once I get the IC engine built I can most likely hit 60-70mph. I went whole hog and spent the money for Gemini racing rims to ensure I don't melt the hubs. I will be installing one hydraulic brake on the rear and two on the front with a possible foot operated emergency brake for the rear. Not sure about that yet. Winter in ND is more for planning and buying materials than building.
