That's probably the most accurate - and the best way to get covered in oil! Don't use alcohol, a light motor oil works best. Also use the correct "engine size". I believe the IMS 440 kits usually come with a 88.5 mm JE piston (431 cc's) and the Wiseco kits are 89mm (435 cc's). Have fun getting the oil out after you're done.
