Yxz help
Starting my own thread on this. To start off my yxz sat outside for 6-7 hours on a very cold night probably around-5* went to start and it would not fire. Pushed it inside next day in heated shop fired right up. Sent the ecu to weller for a flash to help with the cold start. Put the Alba sbd tip on and the ecu back in. Drove it home put in my non heated shop next day won’t fire up again.. started getting a 46 code. Pulled it to my somewhat heated house garage put it on a battery charger for a day after. Code went away and after A LOT of cranking it finally started. Sounded good took it around the block started running shitty above 8k rpms then got a big puff of smoke threw the intake that goes into the battery compartment. Limped it home will start but now it runs ruff at idle no codes just sounds really loaded up. Won’t clean up. It possible I fouled a plug or three with all the cranking? Anyone have any ideas on where else to look? Thanks in advance!
I posted this on yxztalk also just seeing if y’all here might be able to help me in anyway.

Was it flashed for a tip

Kyle said the tune that he put on it would work with the tip all the way to a full exhaust.

Hope it didn't bend a rod

From cold starting? How would that happen?

Timing or fuel issue

Would it still start with a bent rod? I’m hoping it’s just fouled plugs from all the cranking and not starting. At 643 miles I would probably give up on Yamaha if it’s a bent rod

Could be plugs

So had some time today to get the plugs pulled. They were bad. Cleaned them up fired right up and sounded great. 1/4 mile trip down the road then the smoke again and started running shitty again! WTF is going on here? Any advice?
