SERVICING THE ENGINE
Should your engine require service, please follow the following guidelines. Do not return the engine to the place of purchase,
as they are not authorized or equipped to perform service.
1. Remove the engine from the model. We cannot accept equipment for service other than the engine.
2. Along with your engine and proof of purchase, enclose a complete written explanation of the problem(s) with as much
detail as possible.
3. Be sure to include your complete and proper name, address, and daytime telephone number(s).
The charges for repairs will be billed to you C.O.D. Please mention if you wish to have an estimation of repair charges prior
to us beginning service. (This may cause a slight delay in your repair.) Contact your national distributor who will advise you
how to proceed.
If you want to repair the engine yourself, take care of the following:
• Clean the outside of the engine thoroughly before you open it, work on a clean spot, use proper tools. Any dust or dirt
that enters the engine will make considerable damage.
• All moving parts inside the engine are subject to wear. If a piston/liner has worn out, or if the big-end/conrod connection
has worn, you must replace these parts. If the engine has broken you must check that all other moving parts are still in
good shape. If you only change one part and other parts are not in good shape, it is highly likely that your engine will
suffer another failure shortly thereafter.
• If you want to replace the conrod, be sure the big-end of your crankshaft is still round and at a good size, if not replace
the crankshaft. If you do not replace the crankshaft and re-use the engine, a failure may occur such as conrod or piston
breakage.
• If you replace the piston and liner, be sure to check the big-end on the crankshaft.
• These high-technology engines need to be treated with precision. If you are not sure how to modify or repair your engine,
ask your local dealer to do it for you or return the engine to us.
