Hi, just "thinking out loud": maybe low compression is due to the influence of decopressor? As its nature is to lower compression for easier starting.

Aslo, is it normal, that exhaust pipe at the cylinder becomes very hot? See picture, taken in the dark garage.

Yes, when there is no air movement the pipe gets nice and red.

Hi,

Thank you!!!! The more I continue to use the bike, the more it is similar to a self-willed person - it is totally unpredictable. On saturday I have heated up the engine, then I've tried to kill the engine and start it again. No problems were found, the engine was starting very smoothly every time. Lateron, when I've got back after some riding, I could not start the engine for the first time after killing - only during the second or the third time, with throttle fully open.
Also, I've bought new compression meter and did the test. The result was similar to this shown in the picture (I am saying similar, as in the picture is the result of testing of perfectly working KTM 560 six days, 2012). So, I presume, everything is ok with the compression?

No worries, that's why I uploaded those MAP files, so that everyone can access and use them!

Thumbs down

Hi all,

So, my problems with miss-fire where solved by increasing the number of CO trim up to 45, also, by disconnecting yellow/blue wire (I do not know, which action had impact, but when riding in the forest, I have connected yellow/blue wire back - and I could here some miss-fire occasionally and the sound of exhaust has changed. So, I like it with yellow/blue wire disconnected more ) . However, consumption of gasoline has increased accordingly - now I can ride ~ 70 km with standard gasoline tank (I think the capacity is ~ 6 ltr.).
Starting issues were also solved by doing so: if the bike does not start from the first time, I engage the ignition for the second time, then do WOT, later close throttle and press start button - bike starts perfectly. If not, keeping WOT and pressing starter button helps - starts immediately Ufff, my GG acts like a spoiled person.

p.s. BTW, I have a map from Tafka, 2007y, uploaded to my bike's computer
