6 race days, no practices since complete rebuild – this is my race (only) motor. Three first place, three second place in 2014 season. Has several good race days left on it before rebuild. This has the newer coated piston that fixes the problem of the bottom pulling out and/or skirts cracking. I’ve seen these motors go 12 race days without a problem.
52.70 piston, so the cylinder has at least two rebuilds left on it.
18.72 Hp. I’ve been having my engines done by Wolther for 10+ years and this is the best one I’ve seen from them.
IKF/WKA legal – I haven’t done anything to it except scrape carbon off the top of the piston since I got it last March
Some people advertise “how good”, or say “National Level.” Well, here’s one with results and Spec’s. E-mail for pictures and/or copy of last rebuild receipt and dyno sheet.
