I've been aware of Brenny's rebuild service for over a decade. Feeling nostalgic, I bought a neglected 1984 ATC200X to restore. Although it cost some $$$ to ship from WA to IA, I was happy to send my motor to Brenny's. Mark Sr. and team communicated frequently, had the engine rebuilt in a week. Fantastic work! And, it runs like it was new. I'll be sending my next project (ATC250R) for rebuild. Thanks for doing great work!!!!
