i have built 2, and so far heres whats bit me in the ass, the 87 had the huge nice intake side of the cylinder, but only has 6 studs instead of the later 7. the crank bearing issue is easily fixed with a steel insert, which i make. they like to have new waterpump bearing and seal, as they go bad from sitting in water, not a design flaw like most think. plus, from stock, to .200 over bores available? bore a banshee 3mm over and see what happens! thats ten freaking overbores available! I agree with the frame, check it over really well, especially under the motor, and around the front upper shock mounts. A lifelong friend of mine turned me on to these bikes, simply because i had a few banshee's and he wanted something different. He was killed 3 months ago, and I vowed to continue the build of his 87 just the way he wanted it. He had already bought everything to freshen it up, and a few people have donated parts to keep the build going. Bottom line, I am banshee through and through, but I have to build ronnies quadzilla, and ride it to the top of the tallest dune at little sahra here in OK. Hope to see you guys there. hit me up with any questions you have about either bike. love em both!
