I have been a Motorcycle enthusiast and rider for over 40 years. I have always repaired my own motorcycles and in 1978 thru 1981 I raced 1/4 mile drags. This brought the thirst for knowledge on how to build a bike faster then any friends of mine which were all racers. Soon I started building my own motorcycle engines with Big Bore Wiseco pistons and barrels, rings, pushrods and pin race kits, welding my own crankshafts and machine down to fit new heavy duty lower bearings. The engine barrels were sent out for machining to fit the new 3 over stainless barrels and kit. Then I would port and polish my engine head, tear down the head and install stainless steel valves and heavy duty valve springs and a 3/4 race cam, dual timing chain. The Head and Barrels were machined (mirror finish - 2 micro inch finish) to match and seal with no gasket, reducing the compression volumn size compacting the compression for a bigger BOOM increasing the torque :). My carberators I would teardown and have them smooth bored and a 1/4 throttle installed as well as high flow air cleaners. Then Dyno'd for max power output. My exhaust system on my first bike was designed and built by Gary Wolf owner of Wolf Exhaust, who started designing motorcycle exhaust systems in my hometown, he is now world famous for his wolf exhausts on the race circuit. I was the first on the track to race with a dual chain and sprocket I ordered from brownings catalog, funny enough the spline size on the dual front sprocket matched my bike engine shaft and then ordered a blank dual rear sprocket and machined it to fit my rear rim. The dual chain was amazing with more then enough strength for racing and never did I adjust my chain again. I also used a company out of california to order my Trick Tracey Body completely made of fiberglass and weighed only 6lbs eliminating my seat, side covers, rear fender and fuel tank weight from my original bike - Lighter is better, power versus weight. I would also do what we called "Raking the Frame". This entailed extensive frame modification to elongate and lower the center of gravity (cutting away parts of the frame and welding new frame parts) giving a sleeker look and much better riding position for racing. The rear swingarm was also changed for the much wider drag slicks I needed. It also calmed the bikes ability to raise the front wheel and driving much less stress on my rear wheelie wheels that were positioned 1 inch from the ground during my races.
Later in my years I wanted to start my own motorcycle company and did, but to my misfortune the whole plaza along with my bikeshop burned to the ground (arson by a kid) and I had no business insurance, a complete loss. The very next year I found another location and eventually turned my blank space shop into having a showroom, parts and accessories counter, 3 bay shop area for repairs, paint booth, electrical dept and huge outside tractor trailer full of shelved used parts, and a easy to navigate website with merchant account to take any type of payment along with 4 major suppliers (over 250,000 motorcycle Parts, Clothing and Accessories).
This is just a little history about my love for motorcycling and racing. If you ever have anything wrong with your motorcycle or any gasoline engine think of my quote "PUFF, BANG, BOOM Theory" PUFF is air mixture, BANG is fuel mixture and Compression and BOOM is spark - check these 3 areas (Air Mixture, Fuel Mixture and Compression and Spark) and you will find the problem.
