Mail Order Instructions

This is the procedure for packaging and shipping your engine parts for mail-order service:

Find a strong cardboard box. Select a box that allows 4 inches of space around the engine part.

When sending in your cylinder for an overbore kit, please leave the head and power valve assembly intact, that way there are no lost parts or moveable parts that can damage your cylinder in shipping.

For cylinder plating repair ONLY, please remove all spare parts. Send your power valves in a separate bag so we can check for plating flashing in the power valve ports. Make sure they are well labeled or attached to the cylinder.

The best packing material is ‘bubble wrap’. Take care to pack around the fragile parts of engine parts like the bottom skirt of the cylinder, the head’s water fittings, or the crankshaft’s threaded ends.

Enclose ORDER FORM. Print a Service/Repair or Big Bore Kit order form from your browser.

Regarding payment, you can pre-pay with a personal check. You can also have your parts returned shipped by UPS COD Money Order OK, or by Visa/Master Card.

It’s best to send your parts by UPS. Remember to insure the parts for at least $500 (about $4) and get the UPS tracking number. If there is any problem, We can track your package through UPS’s Internet site.

Warranty Statement


We offer no expressed or implied warranty on the life of your engine. Remember, this is a racing machine!

Off road engines are much more highly stressed than the engine on your personal vehicle.

You must take care and maintain your engine. You own it.

Every cylinder that we replate undergoes a 30 point checklist before shipping.

Every engine undergoes a 73 point checklist. They do not leave here with defects.

Even with perfect maintenance and reasonable use, at some point, every off-road engine breaks. After it’s repaired, it is only a matter of time and/or circumstances before it breaks again.

When your engine breaks, we will give unlimited free advice, but we will charge you for all repairs. We love racing, and our customers, but we cannot work for free. Our only source of income is modifying and repairing off road engines. Please respect this, and please respect your equipment.
