second thoughts
 

If you decide to replace 02 sensor I sourced a Bosch brand from the local
auto parts that works correctly for twenty nine dollars versus CSC at one
fifty dollars.
Only replace if after disconnecting sensor and running open loop and reset
ECM the issue goes away.

I will sure look at the valve clearances first, and yes why not, by pen loop you men if i disconnect (unwire) the oxygen sensor bike would still run fine ?


can you show me bosch sensore which you are referring? I can try finding it here..

o2 sensor
 

On my RX3 i had problems with mid range operation from 4000 rpm to 7000 rpm. After unplugging sensor my bike ran good but had a check engine code.
After I replaced sensor I did a reset on the ECM. This requires cycling keyswitch
five times if I remember correctly.

ok that means to make sure if it is a faulty O2 then I should unplug it and check if bike start working fine then that sure is an faulty O2 sensor... I will chk on this.

Some progress....
 

I unplugged the O2 sensor and bike idling turned excellent instantly...



I switched it off and self started it again it took longer self and half open throttle to start and struggled to start with O2 unplugged...


I switched it off again and then again started it again needed at least half throttle opened and longer self to start... but super smooth idling


now this time I plugged back the O2 sensor and started it again this time it did not struggle and instantly started without any throttle assistance but the idling went bad again...



I already cleaned the O2 sensor and dipped it in kerosene petrol mixture over night but seems like that did not helped much...


I think this indicates that fault is really in the o2 sensor? right?

Oops I did it again...
 

So I sold the Rx3 White one a year back... I moved to a 450cc Asia Wing but I hugely started to miss the comfort I was in that little white adv machine..


so I happened to be offered that machine again so .. here I am again... my white Rx3 is now pretty old yet still going maintiance free with new owner...



this new one has very less KMs on its odo..


sharing pics I hope u guys like it..

Definitely The Right Color, This Time
 

Good to see that you upgraded to the fastest color, red; same as mine,lol!

On another note, that front wheel - is it the stock OEM 18" wheel, that someone has painted; or is it a different rim laced to a OEM hub? If it is a different rim, is it the same size as stock or larger, like a 19" or 21" rim?

on my previos Rx3 I had the front stock 18 upgraded to 19 and upgrade is piece of a cake even the stock spokes work with 19 Rim as is...


I have another 19 aluminium RIM lying in my stash whch I will put on this one as well... as it hugely increases the bikes manuverablty on climbing rocks..
