mattb348 Posted April 26, 2006 Report Share Posted April 26, 2006 Hey guys. I just found out why putting an RD 400 crank in a banshee is such a great thing. It apears that all you have to do is get a different ignition system, along with new pistons, when you put the RD 400 crank in. The RD 400 engine is the same exact engine as the banshee, other than the fact that it is 50 cc's bigger, and has an older ignition system. This makes putting in an RD 400 crank ALOT cheaper than buying an aftermarket one. I already have an RD 400 crank; I bought one on ebay for like $35 ($60 after shipping). Now I just need the newer ignition system. Quote Link to comment Share on other sites More sharing options...

FIRST BANSHEE Posted April 28, 2006 Report Share Posted April 28, 2006 the rd 400 is a fast bike,that engine rips. I put the engine in a 250r frame years ago, it was awesome. also had a yz 400 in the same frame, that's also a engine that rips. Quote Link to comment Share on other sites More sharing options...
