martin059 Posted July 3, 2017 Report Share Posted July 3, 2017 I was looking into buying a Banshee 421cc Serval Cub Complete Motor Kit for $2500 on bpracing.com. What does serval mean and 4mill mean ? And does anyone have any input on what what kit I should buy.

ClaudeMachining Posted July 3, 2017 Report Share Posted July 3, 2017 Hi, welcome to bhq. This Banshee thing is pretty new to you? What is your setup right now? Having a more powerful engine mean that you need good supporting parts all around the engine.Serval cub is an engine more trail oriented, with a smoother power delivery than a drag engine. A stock banshee is 350cc, 64mm bore x 55mm strokeA 421cc is a 68mm bore x 58 stroke (+4mm) . 4mill mean +4mm sroke on the crank. Ask questions and read stuff here before commiting to buy.

trickedcarbine Posted July 3, 2017 Report Share Posted July 3, 2017 Where in Michigan? I'm in White Lake. Have you considered the newer Driveline Cylinders? They are out of Michigan. Quote Link to comment Share on other sites More sharing options...

The pin in lower rod end is moved out in the crank web 2mm. So when it's moving the crank goes lower 2mm and higher 2mm. Creating a total of 4mm of additional stroke.

martin059 Posted July 3, 2017 Author Report Share Posted July 3, 2017 I'm in the south haven area. This is the first time I have heard of driveline cylinders I'll have to look them up online. One more question. I've been seeing pictures of people putting double air filters on there carbs. Could I do that with out any major mods upgrades ?

They are available from FAST for a great price for just about any carb set up you can dream. Quote Link to comment Share on other sites More sharing options...
