Hello all,
I bought a new 4rt european bike in feb already derestricted from the dealer.
I like it really as it is my first 4st trials bike.
A month or so ago a long time montesa driver told me, the idle was too high and he lowered it.
The next time I drove it (week later or so) I wanted to drive a step down but it was too high and the engine protection plate had contact with a big stone and stopped my bike while I was still moving forward :-D
The bike just fell to the side so not a big deal.
But afterwards I had to kick about four or five times and it didn't run well and even sometimes stalled at low revs while driving. I believe it also has a louder and deeper sound now.
As I had 15hrs on the bike I changed gear and motoroil, the airfilter and the spark. I removed the cable to the (small) lightmask as it was defect because once before the bike fell down in my garage (due to that ... side stand) and I saw a cable that leads to the o2 sensor not plugged in anywhere and I couldn't see any plug where it could go in... I was told, it isn't supposed to be connected anywhere in a derestricted bike
Everything went well and the bike starts at the second kick but I have to raise the idle (my hourmeter shows about 1800 rpm but I don't trust him ;-) ) too high or the bike doesn't rev up as it should and it is much too weak.
Please see
Has anyone any idea what the problem could be?
