hi, I am now starting to break-in my nwe lrp engine with the heat cycle method, and cant get it to temp, I start it and run it in circles in my garage at low throtle and I only get 110-120f, I lean it a bit to get to 120f, but I am afraid of lean it to much. the weather here is warm. What can I do? lean it more to get the 200f?

Wrap the cooling head with a rag or aluminum foil and use a rubberband to hold it on. If you see that temps start to get too hot, fold down the rag or foil so 1 or 2 of the fins are exposed and get it moving so the air is cooling it down.

thanks but I am doing that rigth now and cant pass 120f any ideas'?

If the cooling head is wrapped and you cant break 180 degree's you need to lean it out some on both needles until you can get those temps. I would only lean the low speed needle slightly. You may want to try a larger area than a garage (dont know how big your garage is), I would make 30-40 feet runs back and forth at varied throttle inputs a few times and see where the temps are.

Lean it, you are doing harm running it at 120F.

ok thanks I will try in my front street

Lean it some. According to every heat cycle method I've seen you should only be slightly rich. Also, be sure to put the piston at bdc when you shut it off to let it cool.

thanks I am doing the bdc thing, but that mean that my engine now has damage because I use it at 120f??

It depends on how long you run it like that. At that low of a temp the sleeve isnt expanding to accomidate the piston, thats why its so important to put the piston at BDC when you shut it down, so the sleeve contracts as it cools. If you are now getting it up to the right temps, I wouldnt even worry about it. Theres nothing you could do anyway, get it broken in and enjoy it.

well, lets hope that my engine is ok, i only ran it like that two times, for like 5 minutes each time. I will try tomorrow to do it in my front street because now it´s raining heavily, as always that I got a new toy...[:@]

Racing T

finally I am getting the temps, I have to lean it in order to get 180-200F, hopefully I didnt make any damage.

Use a heat gun on the engine.
