- 2008 Yamaha nytro 153 mcx190
2015 SRViper mtx se 162 mcx270
I have an 08 nytro with a 180 mcx turbo and today it suddenly started idling on two cylinders for short periods of time. Then once i burped the throttle a bit it started running on all three again. It did this several time until i headed back and it was fine the whole way home and now is still running on three. It seems like if I was holding the throttle constant at a slow speed this is when it was happening.
I had done some recent updates on the sled including, replaced exhaust donuts and welded cracked exhaust mounting bracket, updated mcx box to 190 kit and readjusted the boost to 7lbs. Spark plugs where changed last year. Any ideas?
