Hi guys, Recently just had an SR 125 nicely rebuilt with a Malossi 172, main bearings and seals, Malossi carbon reeds, technigas exhaust, new rollers, 2 stroke pump belt, CVT belt, rollers, fork seals, front pads, seals and brake fluid. I heat cycled it a couple of times as advised before riding it and made sure not to pin the throttle I lowered the clip to the notch one above the lowest (Mikuni VM20 carb), put in a 94 main jet and took it for a plug chop, when I took the plug off after WOT and turning the key and killing the engine at 60mph I was horrified at what happened... The plug was grey and smoke came out of my engine for about 45 seconds after removing the plug. I am worried that the engine has ran lean and maybe already overheated. I have not ridden it since and I'm waiting on some 98-106 jets that I've ordered and will be putting in the biggest one first, plug chopping it and hoping I haven't nuked my engine.
