Bad engine miss
Wish I had known you when my kids got into bikes, expansion chambers. ? ? ? Lol
Yeah, 2-stroke race-bikes are a different animal. I work on those, but I don't engineer them. Guys used to bring me boxes of stuff and say, make it work, lol. I had a friend, smarter than me in that arena, who engineered the engines, and I just bolted it all together, and said "good luck". Cuz, as you know, that's 2-stroke racing, lol.
You gotta stay on the bike to win, and every young boy dreams of being first into turn one, and leading the race after that, lol. All 15 of 'em. Yeah it takes a lotta driver skill, driver power, and driver stamina, etcetera, but mostly, that first lap is all luck. One wrong bounce at turn one, and everybody goes down.
When my boy was around 12 or 13 I bought him a worn out Honda 4-stroke. It had a decent engine but the chassis was just bagged right out. We lived in a hick-town, in the country, with an old railroad track allowance about a block away. I told him to idle out there and go nuts, knowing that suspension would limit his exuberance.
Well it wasn't long and he was wheeling that lil 200 all the way down mainstreet. Criminy. Now I gotta make rules?
Next came stoppies with drum brakes. Then Poweslides. Every time I made a rule, he was like SmokyYunich, finding a way around them. Finally, he was a tad older and stronger and so, I said you know what; in two summers you haven't broke your neck yet, just go ride and don't let your mother see you. Shazzam, He was gone!
