Winter Project Update

Our Winter project bike is coming together nicely.  To recap, we started out with a 1997 Yamaha YZ125 that had a blown engine and had been left abandoned outside for several years.  We started out by completely disassembling the bike down to the last nut and bolt. The frame was sent off to be repainted ( Lexus silver ). While that was off we rebuilt the shock linkage and swing arm pivot with Moose Racing bearing kits. Linkage lubrication is done with Bel-Ray Assemble Lube. NOTHING works better for keeping the linkage working properly. The steering head bearings were replaced. Both front and rear wheel bearing have been replaced. As well as tires, IRC Heavy Duty racing tubes and rim locks. Both Brake calipers and master cylinders have been rebuilt using Moose Racing rebuild kits. Reassembly has begun with the swing arm back on the frame and both suspension units ( front fork & rear shock ) are back on for mock up. They will be gone through before final assembly. UFO plastics replace the weathered stock parts.  UFO plastics fit just like OEM parts and hold up better.  A new UFO Chain slider and rear chain guide wear block along with new chain rollers are installed. The Stock aluminum rear sprocket

was replaced with a longer lasting and stronger JT Racing steel sprocket for off-road racing. The stock wheel had one rim lock installed, but a second one was added for extra flat prevention and to help hold the tire on the rim in the event of a flat.  IMS foot pegs replace the stockers for additional rider comfort.

As each system and part is carefully reassembled, lubed and adjusted, everything is tested for proper operation. Insuring that when this bike is ready for racing it will be better then a brand new bike off the showroom floor.

Special attention is being paid to handlebar and brush guard selection for rider comfort and durability. Answer Protaper Contour bars are being used for strength as well as Answer Protaper grips.  A new front tire along with IRC Heavy Duty racing tube is installed. Extra special attention has been paid to the front brakes. New EBC pads and EBC brake fluids help increase stopping power along with proper servicing and adjustment of the front caliper alignment.  Paying special attention to the small details is what makes the difference between an average bike and one that has been set up for racing.

Assembly of the remaining body work, seat foam, seat cover and graphics can proceed as the engine is being serviced. Last time we showed the how crank assembly was finished. We installed a new rod assembly and bearing.  Now we have the cylinder out being re-chromed as the lower end is being reassembled. New crank bearings , crank seals, engine gaskets and seals are being used in the reassembly process of the YZ125 engine continues.

Winter Racer Rebuild - Save Money & Make Your Old Bike Better Than A New One!

Stripped to the frame, cleaned, repainted and then the reassembly process begins. Attention to every detail. Making sure all the moving parts get proper adjustment, lubrication and are working perfectly. Suspension units are serviced, lubed and adjusted for the racers style, weight and ability.



Properly working suspension will make your bike preform like it was supposed to.  Most often over looked because it is a messy, time consuming job. Most people's suspension is working like crap! Taking the time to service yours will put you one up on the competition. This shows how dry and non-responsive rear shock linkage can get when not properly serviced. You should be cleaning and regreasing your suspension linkage two to three times a year. DON'T wait until it "squeeks" before servicing it!



A complete engine tear down and inspection. New Crank bearings and seals, Transmission gears and bearings are inspected. Never reuse crank bearings and seals or gaskets.



Crankshafts can be rebuilt for less then half the price of a new assembly. On small displacement bikes replacing the connection rod, and lower bearing and pin is a must. 



Rebuild the cylinder don't replace it unless absolutely necessary.  If you are rebuilding it, have it replated NOT sleeved. Modern motorcycle engines have plated cylinders. The engine is engineered to run properly with a plated cylinder. Sleeving it will change how it runs dramatically, and not for the better. Do it right, replate it.  Replace the piston, don't try to reuse high wear parts like pistons and rings. Good mechanics replace worn parts. If your bike is worth fixing, it's worth fixing right.  Always use new gaskets.  There is an old saying...there is no such thing as bad parts, only bad mechanics.

That's it for now. Taking the time to rebuild you bike correctly will make it perform better then someone that takes a brand new bike off the showroom floor and just races it.  Next time we'll talk about how to make this freshened up racer look as good as it performs.

Great For Winter Storage!

S100 MOTORCYCLE CORROSION PROTECTANT  No matter how clean you keep your bike, you always have to be on the lookout for that dreaded “enemy number one”, corrosion.  Unless you live in the desert, humidity, salt air, spring road salt and plain old pollution threaten your bike’s “precious metals”.  That’s why S100 developed Motorcycle  Corrosion Protectant.  Just spray on a clean, dry bike (or into a cloth) and rub into the areas you want to protect, those sensitive areas like fork tubes, chrome exhaust pipes, case covers and wheels (and don’t forget those hidden areas you can’t reach.).  You’ll find that S100 Motorcycle Corrosion Protectant won’t rub off easily in the rain and so its protection really lasts.  It even dramatically out-performed a famous so called “corrosion fighter”, so this is really the way to protect your investment! "Daytona Beach Salt Spray Tested!" Important note: This is the perfect product for winter lay up and long term storage. Spray directly on all sensitive areas and allow to dry. 7.2 oz can. $9.95  http://www.kevinscycleracing.com/crbikecare.htm
