RE: ASP/MAGNUM FS400AR Rebuild/Overhaul
Hi Waldo,
I agree with Kmot on this one. Lighten the load on the engine as I found that I would loose cylinders when the rpm was below 7000 or so. Also there has been some discussion regarding cooling and baffles etc to prevent overheating, you may want to look into this as well. A peak at your valve clearances wouldn't hurt either
