| Moto Rapido, LLC shop rates Two-stroke engine rebuilding Two-stroke engine rebuild labor price: $300. This includes replacing all bearings, bushings, and seals, installation of new piston, pin, bearing & rings, lapping head if necessary, replacing any transmission components or other engine components that are worn or broken, and installing new points & condenser. The basic techniques in engine rebuilding are nearly universally applicable. However, most engines were designed with unique engineering twists here and there. To guarantee perfection, it's best to work under the guidance of a shop manual or Haynes or Clymers manual that gives details of unique requirements. If you can't supply my with your own copy of such documentation, I would strongly recommend that you add the modest cost of buying shop documentation (or finding it online for me) to the job. It's an inexpensive investment that will ensure good results. Port matching, port timing modifications & port polishing Porting & polishing work is negotiable depending on type of engine & customer's instructions. Carb rebuilding Carb rebuild is $25. Crank rebuilding Crank rebuilding is generally $50. This includes pressing apart the crank, installing new pin, bearing and con rod, and truing to within 0.0005" Truing work done between precision centers, using precision dial test indicators for accuracy. $25 extra charge if crank is rusted & needs bead blasting. Note: while the lobes can be ugly, the stubs must be clean and undamaged at seal-mating surfaces and bearing-mating surfaces. Tapers must be clean, and keyways sound. Threads should be good. Center holes on crank stub ends must be perfect. If somebody used a hammer on the crank stubs and distorted the ends, it's nearly impossible to true the crank. I'll polish cranks with damaged center holes and you can use them for a paper weight. Stator rewiring Stator rewiring is $25. Includes cleaning stator plate (solvent or bead blasting depending on circumstances). Lathe & milling machine work Custom quotes, vary with job complexity. Zinc plating & black oxide finishing Plating & finishing varies by part complexity & quantity. Bargain rates for one or two pieces (most shops charge at least $50 minimum). Coffee can of fasteners approximately $50. Important: parts must arrive ultra clean for plating. Must be solvent cleaned, de-rusted, bead blasted and possibly polished for achieve quality finish. Preparation work for plating is tedious, and I'd rather not do it. If I have to, it will cost $50/hour. Save yourself the money and do the preparation yourself. Metal polishing Engine case polishing is $50 Other polishing jobs vary greatly by complexity of parts. E-mail for quote. Who orders parts? You or Moto Rapido? Moto Rapido doesn't add a markup to parts required for rebuild work. You can buy the parts and deliver them along with the engine or bike for service, or Moto Rapido will order the parts from your favorite supplier with no markup. Our preference on bearings & seals is to use SKF brand or equivalent, and Chicago Rawhide seals or equivalent quality. Skimping on bearings and seals is false economy. Save $5 by buying an inexpensive, lower quality bearing, and regret it later when you have to pay somebody to tear the whole engine apart to replace it when it goes bad. contact cjmark@panetwork.com for quotes |
