blueish is good actually perfect if its always blue even at hot temperatures then u maybe a bit rich on the fuel or 2 stroke oil but sure is better then white. and for your break in procedure honestly this whole heat cycles bull is defiantly your BEST break in. BUT dont chew yourself up about it just cuz u dident do the "perfect" thing like some of these rocket science / pro blaster builders. hahah never been bothered doing these rather long heat cycles hell my tores system stuck on my bike the very first start after rebuilding my blaster and she got about a 15 to 30 sec rev limiter hows that sound for a heat cycle break-in process (kill switch wouldnt shut-er down eather had to stall it out cuz of pre-ignition) MAKE SURE THIS DOSENT HAPPEN CUZ IT IS NOT GOOD ON FRESH MOTOR that was well over a year ago and my bikes still running strong. so your drive after rebuild is no problem, now in saying that dont go for a tour for hours and over heater but u can see what im sayin. aswell when breaking in keep the rpms low/mid and throttle away from wide open and youll be ok. I find some people on here must be yamaha factory race blaster rebuilders or something cuz these cycles r a bit drastic BUT im not saying there wrong they r your best bet but honestly arnt a MUST so u dident go abouts the breakin wrong at all its even good u checked the tenson on your bolts after. hahaha i laughed hard when i read " u rebuilt it today and road it today?????? i mean what do u expect to rebuild it and look at it till the end of the day ? WELL by the looks of some of these guys clean bikes that may be the case :s just had to put that straight for ya hoped this helped
