Worlds Fastest Dirtbike Mechanic 2007 CRF250X
Worlds Fastest Dirtbike Mechanic 2007 CRF250X I decided to rebuild my bike this winter so here is the result of this rebuild. This is a list of what the bike got..... New Tires Powder Coated Rims Powder Coated Hubs Powder Coated Clutch, Ignition, and Valve cover Powder Coated Wheel Spacers Powder Coated Axel Blocks Wiseco Forged Piston and Rings PIAA High Output Light New Grips New Throttle Tube Engine Ice Fresh Fluids and more..... The entire rebuild took me 8 hours but we managed to chop down the video to 4:30 with a lot of time and effort. Also here are the pictures from the build http://flickr.com/photos/33640028@N04/sets/72157612870999959/show/with/3220 736119/ *Credits* Builder - Scott Carter Video Editor - Greg Ferrucci Powder Coating - Jawa





1987 87 Yamaha YZ 250 Rebuilding
A totally rebuilding for a 1987 yz 250. We had to change the right inner case which was craked, to repair the Exhaust system, to check the carburetor, to clean all the mechanical parts, change the bearings, add a new sprocket, rebuild the stator with new coils, clean the flywheel, replace the clutch and check the power valve, adjust the rear brake and also giving a general restyling





YZ250 Port Teaser and First Start
Had to take care of the top end of my YZ250. I took the opportunity to make my favorite port adjustment that DeoVindice showed me. Have to keep the details under wraps since they're "proprietary", but it makes for great gains in bottom end power even with a mid range pipe. I think this adjustment is a must for any two stroke no matter the type of riding, but woods riders/racers like myself will benefit the most. I also attempt to redeem myself for the 250R first start vid. I get it fired with a few kicks, but the first time I run it around the yard I left the choke on so the engine sputtered and smoked a bit. Once I turned it off it ran cleanly and felt like the port work did what I wanted. Since making this video I've taken the bike for a couple of rides and the change is dramatic. I can lug the bike up difficult terrain without too much effort, but then it really wakes up in the mid range (a little too suddenly thanks to the damn FMF pipe). Carb still needs a little tuning and if the bike had slightly more low end power it would be perfect; might be able to coax a bit more out of it the next time it's due. I let a friend ride this and he said it felt like a four stroke.

1986 Honda CR250 Restoration Back from the DEAD
This is a 1986 Honda CR250 that I rebuilt. It was in better condition than the 1988 CR250 that I rebuilt. Here is a partial list of what I did: -sandblasted the frame and powered coated -new "modern era" footpegs -new water pump cover -split cases replaced all bearing and seals, replaced rings -new plastics -new air filter -all new decals -new grips -new levers -plenty of new hardware -rebuilt and rejetted the carb -suspension all rebuilt and set up for my weight. Front and rear suspension have Race Tech "Gold Valve" kits in them. -greased the front end bearings -new wheel bearings -all new suspension linkage bearings -new fork boots -new swingarm sliders and guides -new chain rollers -Boyeson Ignition Cover I spent way more rebuilding the bike than what it is "worth" but is was every every cent and every moment I took to bring this bike back from the it's former sad state. A very enjoyable experience. I must give credit to Dave over at the Motocenter in Tempe, AZ 480-642-6686. www.motocenteraz.com He did the suspension and engine rebuilding. Dave should change his name to Mr. CR250 after all the time he spent on this bike.
