Re: Vapor honing
Here are some photos of what we vapor blasted this week and last. Keep in mind engines must be 100% disassembled before vapor blasting. Blasting a complete engine is too risky as media will ALWAYS find its way in!

2002 Laeger's 250R Based Hybrid
Hey everyone! Its been many years since I have been active on this forum but I thought I would share a "250R" related project with you all. Here I will be documenting my 2002 Laeger's (250R Geometry) CRF450R hybrid. This is 1 of 7 CRF chassis that Mark Laeger produced before selling the remaining off for CT Racing to complete. The first 7 original chassis can be identified by the unique front motor mount. This bike specifically utilizes CR500 linkage and a Pro Trax MX width front end. I must confess that if anyone has been following my DBC Racing social media pages this is not my first time putting this specific bike together. This winter I tore it down to address some minor issues as well as re-powder the frame, arms, and swingarm. The shop that powder coated this for me in January of 2020 did a terrible job. Powder was majorly under-cured and it was chipping to hell pretty much as soon as the bike got ridden. So the old powder was chemically stripped and re-done by TLR Coatings here in Michigan. This specific chassis utilizes all 250R components other than the motor, exhaust and carburetor (Yes I know I am stating the obvious!) Anyway, I hope you all enjoy the progress as I document the project on this thread. I hope you all can appreciate it even though its a four stroke power plant! March 01, 2022, 06:44:07 AM |

Re: 2002 Laeger's CRF450R Based Hybrid
Here are a few photos of the Rocket Machining and Design front and rear billet hubs. Similar to the Hardkor rear hubs (yes thats right Hardkor made rear hubs), the rears utilize a splined stainless insert. A full billet rear hub with aluminum splines will wear out overtime and develop some slop. The SS insert solves this issue. See the 3rd photo for a look at the SS insert I am referring to.

Re: Polishing (service)
380 LYNX. I haven't even ordered the cylinder yet. This bottom end will be sitting on the shelf for a while until I get around to it. April 14, 2022, 06:17:08 AM |
