SICK BOY Posted August 21, 2004 Report Share Posted August 21, 2004 If you ran a whole tank of gas through it already it should be pretty much broke in. Quote Link to comment Share on other sites More sharing options...

fixitrod Posted August 22, 2004 Report Share Posted August 22, 2004 There is a search function at the top on this site. I've answered this same question 3 or 4 times in the last month. Eric Gorr has built motors for a very long time. I use his method for breaking in a motor... Here they are from www.ericgorr.com Breaking In a New Bottom End The new lower end will need some patient break-in time. The best way is to let the engine idle for three separate 10-minute sessions with a 20-minute rest period between sessions. You don't need any extra pre-mix oil because the engine load is minimal when the engine is idling. Top end break in 10) When you initially start the engine after a rebuild, manipulate the choke to keep the engine rpm relatively low. Once the engine is warm enough to take it off choke, drive the vehicle around on flat hard ground. Keep it under 2/3 throttle for the first 30 minutes. Two common myths for proper engine break-in are; 1) Set the engine at a fast idle, stationary on a stand. 2) Add extra pre-mix oil to the fuel. When the engine is on a stand it doesn't have any air passing through the radiator and it is in danger of running too hot. When you add extra oil to the fuel you are effectively leaning the carb jetting. This can make the engine run hotter and seize. Quote Link to comment Share on other sites More sharing options...
