How Mike Cradock Breaks in and Tunes a Reds Racing Engine in Kyosho Inferno MP9 TKi3/TKi4.
If your ambient temp is below 10c you may want to use an engine warmer for the first start. We didn't in the video as we were at 12c on the day.
For the first tank start your engine check no funny noises and warm up engine gently to about 60c then take it up to about 80c using no more than half throttle to take up the revs to warm the engine like shown in the video. Then let it idle to cool down to 60c again to heat temper the engine. Repeat this for the first tank of fuel. There should be plenty of oil exiting the pipe so look out for that. We use a fuel with 12% oil.
Start engine check no funny noises, warm up gently to running temp then tune to how you would like to race it meaning how it feels when you are warming it up for a qualifying heat.
Then take it on the track and run 2 tanks up to half throttle then 2 tanks at 3/4 throttle then 2 tanks just touching full throttle backing off just as you are hitting full revs. Keeping engine running all the time as this helps with heat tempering the piston & liner.
Once you have done this give it 3 laps and check temp you are aiming for 85c plus ambient temp so if it's 30c it should be 115c
Once you have the temp controlled run it flat out up and down straight and bring to a stop. Should idle for 30 seconds then hit the gas flat out it should have a small splutter then pull away. If it pulls away clean then richen bottom and try again. I like to run the bottom a little richer and top so it really screams down the straight. Hope this is helpful.
