Default Newbie needs your help.. Please!

Hi all,

I have today brought a Kyosha mad Force Kruiser. I had a few issues getting it to run, mostly down to my impatience!, but now have it going. However, it seems to be burning quite a lot of fuel and sometime cut's out after full throttle.

Is there a way to re-set the KE25 motor back to factory setting and start again, as I have changed both the Hi and Low speed needles, and want to be sure that I run the motor in correctly.

Thanks in advance.

partly I am a little afraid of the changes I have made and don't want to mess up the new toy!

yes, it is a new engine. I didn't do any of these things yesterday! hope I haven't caused any damage..

In terms of the engine temp, I didn't get a device to indicate this so guess I will need to get one of these in order to complete the break-in??

Thanks again

No not really when I ran nitro i used the spit test . Water boils at 212f so i just spit on the head and watched how long it would take to evaporate off . lol , But of course I did buy one . For nitro I always liked the mip or traxxas on board guages they give you a reading over the whole run as well as the peak temp.

A cheap infrared thermometer would probably be a good idea.
But you dont absolutely need one.
For many years people have gotten by with the so called "spit test".
Just put a drop of spit on your finger and put the spit on top of the cooling head.
If it doesnt evaporate too quickly, the temp is fine.
So what is too quicly then? well about 3 seconds depending on how much spit there is

Anyway, you will probably be better off with a cheap temp gun

Thanks for your advice folks

I've had a lot more luck today getting the truck started (unlike yesterday!) but now the BIG question is about getting the HSN and LSN set correct

Whilst I now know that I need to run-in the engine, it seems to go ok but I have noticed a lot of fuel spitting form the exhaust and tried to lean out the HSN but this seems to make no difference (on the understanding that I have the car idling and make the change there and then).

Also, based on some experiences of others my truck seems to have strange settings in that the LSN is nearly all the way out and the HSN about 5 turns open from fully closed.

Any ideas???

Thanks in advance.

When the car is idling the high speed needle has almost no effect on things.
If you want to lean it you will have to do so on the low speed needle.
With that being said, since you are still breaking in the engine it is probably a good idea to keep it like this.

Ron from werks has another approach to engine run in, i havent tried it yet, but it looks good and easy to follow

its in the first post of this thread :-)

Thanks again Kaan, I will take time to read through and try!

I had it running quite well yesterday and the fuel spitting seemed to be a little less..? Maybe it's down to the engine becoming more run-in..?

All the best,
N
