I’m Eric Gorr and I’ve specialized in performance engine rebuilding since 1976 when I founded my business. My performance rebuilt engines have won World and National Championships in the motorsports of Motorcycling (MX, Hare Scrambles, Dirt track, Road Racing and Trials) Snowmobiling, Karting, and Formula Auto, (2&4-Stroke). I love dirt bikes and specialize in late model and vintage 2-stroke dirt bike engines made in Japan and Europe and I have all the special factory tools to do the job right the first time. For late model bikes (1995 and newer) I offer comprehensive engine rebuilds featuring HOT RODS BOTTOM END REBUILD kits and your choice of Vertex, Wiseco, or Pro-X piston kits and offer all-inclusive package deals and the model application and price chart is listed below.
For bikes made in 1994 or earlier it’s a little more complicated because the Japanese and European manufacturers are discontinuing parts for these bikes and some manufacturers are out of business entirely. The recent earthquake in Japan and the Fukushima nuclear crisis destroyed a lot of infrastructure and tooling as well as vendor’s businesses. That natural disaster affected mostly Honda and Suzuki parts. There are aftermarket and new old stock parts available for more expensive prices and that’s why I don’t offer all-inclusive prices on those models. If you have the time and patience to work Ebay and NOS stock that’s cool if you supply your own parts, I’m not one of those guys who gets pissed off if you supply parts and I think you’ll understand that I won’t guaranty the quality of antique parts. I’ll work with you on any vintage project because I know this stuff really well and I raced mx, dirt track, trials, and road race since 1971. I’m also a best-selling award winning writer of 6 motorcycle books and have an amazing collection of technical history from living and departed tuners, factory directed mods, and interviews with thousands of enthusiasts. I was born in 1957 and I’m part of the “On Any Sunday Generation” so I GET IT!
Unlike most of my competitors I offer you the opportunity to supply your own parts because I know that vintage guys hoard parts and have connections from social networking forums as well as sponsorships from dealers and manufacturers. So you’re welcome to supply your own parts and I’ll even give you an itemized list of what you’ll need after I disassemble the engine.
LABOR: Minis to 125s $295 and 250 to 550cc engines $395. (For when you supply complete crank, bearings, seals, gaskets, piston, and any other parts including gearbox and clutch)
ENGINE REBUILDING - WHAT’S INCLUDED?
There is a much more thorough description of how I check and rebuild each component listed at the bottom of the page. Generally speaking the engine rebuilding labor includes;
- Cleaning and Disassembly of the complete engine.
- Inspection and Measurement of all the engine components.
- Polishing of clutch parts, shift drum and forks, and crankcase ports.
- De-carbonning of the powervalves and cylinder head as well as diamond honing of the cylinder bore.
- All the seals and bearings are changed and pre-lubed, crank and gearbox installed, cases sealed, crank centered, and top end installed.
- ERIC’S PERFORMANCE RACE BUILDS NEED NO SPECIAL BREAK-IN, JUST GIDDY-UP AND GO!
