thanks...bike is 2007 night train...tmax/at....had not started the bike since october 09 cause of my 'remodel' project which took me way too long for many reasons....
have the tmax for about 2 years and never had such problem...so loaded base map, clear learned stuff, initialized, started until temps reached 280 then shut it off...ten minutes later start again, in a few minutes notice the check engine light is on, so connected to the pc and said a problem with the rear o2 sensor (AFR 19.36)...shut the bike off and did not ride the bike...the next weekend changed my exhaust, did the tmax setup and the same thing happen except this time it's the front o2 sensor, the rear one is fine...got the dtc code thru speedo

i meant getting it on the sensor will cause issue. i just recently added electrical grease to the connections for the o2 and also the data port, the grey 3 wire port. when your bike is off and you connect the computer and turn on the hey it goes to 19.36 when the heater in the o2 is on. if the connections are ok then get another o2 sensor or a pair if you can afford it. if you get only 1 new one put it on the back so the next time you need the front it will be easy to replace
