Why is my bike so slow ?? How come I'm always tail-end Charly? It's been bugging me for a while, all other bikes are quicker than mine. And I've been following all the good advice I've been getting: Taken out the air-box, flatten the power-curve with a 6-pound hammer, took all the garbage out of the cans, changed the power-band (which I was told was too narrow) for a wider one. Last weekend I filled the "holes-during-accelaration" with a bottle of Poly-Urethane Foam, mounted an amplifier in the helmet to get a better response from the engine, swapped the sprockets back-to-front to make the rear wheel turn faster and fitted stronger piston-return springs. I'm also filling up with leaded, making the bike heavier and hence lowering it, reducing the frontal area (less wind, more speed). Nothing really helps!! Now I'm told to check the valves, out of the 8 I'm supposed to have I can only find 2 ( those sales-guys are full of shit) and they're at the wheels. I also extended the legs of the centre stand to avoid roll-resistance. Replacing the sparks with fresh ones didn't help nor did the removal of the idle-speed-overflow container. As brake fluid builds up during use of the brakes I keep draining the stuff weekly. I also spray the aircleaner with White King regularly to have really clean air and drench it in Fly Spray to keep the bugs out. Last night I also junked the radiator replacing it with a Fast-by-Ferracci drinkbottle which hopefully should make it go as quick as it says on the bottle. Replacing the stock tank with a Sherman wasn't a good idea, couldn't see shit once mounted to the bars. A mate is going to get me some of that Repsol Paint , but that'll be in a fortnight or so. The only result I had was after glueing the 5th sharkfin onto the top of the helmet (with an extra 2 out the sides for stabiliziation), now I can hear the wind whistling by and MUST be going at least a little bit faster. Since I'm not stupid, I also thought of drilling a hole into the rocker cover, fitting a Scott-Oiler attached to a 1litre bottle of Tabasco-Sauce stashed under the seat (where the airbox was), so I've got a hot cam. Also fitting a 10" front wheel makes at least the front goes fast (I'm still respoking the rear wheel with knitting needles, they're hollow and therefore lightweight). Great advice from a guy in Ivory Coast... Tried a camshaft off a 4-cylinder (bend slightly since it didn't fit right off) which gave me more "lobe". Of course I cut off the excess bits sticking out of engine casing. Update: Got the chassis sorted now, yeeha. Great cornering-clearance now after taking the engine out altogether and mounting the footpegs to the handlebar. Any more ideas?
