Chopper, we’re gonna push that bike to its limits—got any tricks to crank up the power curve and shave seconds off the lap time?
Chopper
Yeah, keep the engine clean and replace any worn bearings. Tighten the timing a bit, but not over‑tight. Swap to a higher‑grade camshaft that opens later for top‑end boost. Use a better throttle body so air flows faster. Check the exhaust for any restrictions. And make sure the fuel mixture is right; a slight lean gives more power at high RPM. Clean, tweak, and you’ll see a drop in the lap time.
Laron
Solid plan—clean the engine, swap that cam, tighten timing just enough, bump the throttle body, clear the exhaust, lean the fuel. Give me the exact specs and we’ll hit the track tomorrow. No excuses.

Use a 140‑degree cam, 240/215 ° duration at 0.050‑in lift. Set timing to +5° at 8000 RPM, keep it in the 0‑8000 RPM window. Pick a 1‑inch throttle body. Swap the stock header for a 4‑inch straight‑pipe exhaust. Lean the mixture to about 12:1 at top end. That's the kit—clean the engine first, then you’re good to hit the track.
Laron
Got it, that’s the sweet spot. Clean the engine, swap those parts, and we’ll be cutting seconds off the lap. Don’t waste time—get it done, get results.
Chopper
Sure thing. Strip the old cam, install a 140‑degree with 240/215° duration at 0.050‑in lift. Shift timing up by about five degrees at 8000 RPM, keep that window. Fit a 1‑inch throttle body and swap the stock header for a 4‑inch straight‑pipe exhaust. Then lean the mix to roughly 12:1 at the top end. Clean the whole engine first, then you’re set to cut the lap time.
Laron
Sounds good—stick to that plan, keep the timing clean, and you’ll see the numbers drop. No excuses, just grind. Let's hit the track and prove it.
