Impressive work! It's much easier on the pickup though with no floor to contend with!
How do you plan to connect the prop shaft to the sprocket?
I spent yesterday taking the engine out of one of my vans and it was quite a pain in the ass. It blew the head gasket so I'm having to replace the engine but it's just going standard again.
Getting an adapter sleeve made up that fits over original motorbike sprocket. This runs a shaft with a large sprocket which then powers a smaller sprocket on another shaft by chain which has the electric reverse and the flange for the propshaft. This allows you to get the correct ratio for the drive. Bike has 2.4-1 ratio on 17" wheels, Rascal is 5.1-1 ratio on 13" wheels. Direct drive to the bike engine would leave you doing 59mph on the limiter in 6th!!!!!
Gonna keep the engine at the moment in case all goes tits up!! When time to sell it will let you know Bryan.
Few more snaps of the progress. Engine now has clutch connected up, gears connected, and coolant system finished. Running like a beaut. Bought a dynojet power commander as well to boost her up a little LOL
dash fitted

Just waiting on driveshafts/flanges to be fabricated up.
first shaft fitted and tested. Ran up to speed in 6th and quiet as a mouse. Lightweight flywheel with ring gear for electric reverse also made up and balanced. Starting to fit the second and final shaft now. Big shout out to exact engineering / Newry motor works fellas for the excellent work they have done on the drive system machining.
i have never seen an adapter like that, thats very cool looking !
I am no engineer, but would it be strong enough ? the links of a chain would be braced on both side of the tooth of the sprocket, where as the studs above are only fastened on the adapter side , would a jolt from the engine not be able to strip the studs off the adapter.
Dont think for a second i am critiquing the design , im certainly no expert, just interested in how it works
More than strong enough! There is 17 10mm hardened pins pressed in the adapter. On the original chain has the joiner, links but there is the pins which join them and they are only about 3mm.
Got the mock up of the second shaft with the electric reverse flywheel, sprocket test fitted for dimensions for length and drive flange position last nite. Am now armed with the length of the driveshaft required and position and going to leave it in tomorrow to start to be made.
