twin engine drive-train clutch setup

#1
i've got to thinking about building a bike with two meth burning briggs engines, with the clutch, is there a special sprocket for engine #2? say if one engine is running more rpm than the other, will it be pulling? something where if the front engine is pulling, it has like a ratcheting effect?
any help is appreciated.

Contact OldMiniBikes member "smallbore". He has a twin engine bike that I have seen at some local So Cal get togethers- It is REALLY cool!:thumbsup:

Or see BigRob's twin engine build off bike from 2 years ago. Isn't it Scootercat (not sure of the user name) that has a twin Predator build.

So... could you start the front engine and let it warm up and then when pulling away from a stop, the clutch on the first engine would engage and start the rear engine?

Yep start the front engine then give it some throttle it will start the rear engine
.
Think of it this way its a regular minibike setup and the engine that drives the rear wheel just gets extra help from the engine thats chained to it
.
Someone always says that the engines have to be synced . With this system both engines have the ability to slip via their clutches hence they will find their own sync automatically

Twin engine builds rock!
On mine I used two seperate clutches linked with a chain running on ring sprockets welded to the outer rim of the clutch bells
I am at work but will try and post a pic after work
