Hello all I have a problem I wonder you could help with. About 3months ago I bought a new Hanway scramble right 125, even New the bike had a few issues of cutting out when idle..a lot. I took it to the garage where my mechanic fixed a poor solder joint and removed some water from my tank that had also made its way in somehow, along with first service, oil change etc + I asked them to alter the mixture to stop the judder as I suspected it was too lean. After this it rode like a dream for about a week but is now having the problem of juddering and intermittent power loss when I try take it over about 6000 rpm in 5th forcing me to not go over this. Checked fuel lines for kinks but it seems ok and am kinda out of ideas/ lack the knowledge of what to check, any ideas appreciated and can provide more details if needed. Thanks in advance
