Pullstart Conversion Services

 

We offer pullstart conversion services for the full line of RB Concepts engines. These include the S7, WS7, S7II, WS7II, C4, and C5 engines. To accomplish the mod on the S7 and WS7 engines we require the customer to send us their crank and an impeller unit from a Ofna Hyper engine. We drill the crank, press the one way bearing and pin from the impeller and press into a part we developed and provide. Total cost for this service is $90 complete. Customer will need to aquire the backplate assembly, pullstarter unit, and starter shaft from the Ofna Hyper engine to complete the modification.

Conversion costs on it are $150 complete. Customer required to send complete engine and all required pullstart pieces from the Ofna Hyper.
