Hi there OldMiniBikes! It has been awhile since I have posted anything so I thought a little update/introduction would be in order. Long time regular reader and browser of the site and I have learned so much from all of you and am thankful for being exposed to that knowledge and humbled by being able to...

Me again... Well hopefully this is the last hurdle I have to encounter. When I first finished my Raptor 2 rebuild about a month ago things were going great. Until when on a run I heard a high pitched squeal coming from my engine. I immediately stopped and turned the engine off; the noise...

Hey guys, Relative noob here with a homemade frankenbike. Planning on going to a bigger sprocket on my rear axle to gain more acceleration. I'm getting a tad bit concerned about clearance as my current tire is a 13-5.00-6. I have a 4" wide rim at the moment and would prefer to use it when...

Hey guys Been reading up on the billet flywheels out there and how they are a great investment. I'm pretty much sold on getting one for my stock Raptor 3. Just wondering about the stock Raptor 3 flywheel and what it is constructed of? Because it is an un-governed engine and I've read about...
