Hi all.
I've been experiencing issues recently. Bike starts from cold, and revs etc just fine. After about 3/4 mile of calm running however, IE as the engine begins to warm up, She starts to miss, cough, and won't rev. This progressively worsens, until she won't start at all. Couldn't find any trace of air leaks etc. After weeks of diagnosing, and testing, (I Did find a duff TPS, completely losing it's reading at midrange throttle settings) she now has a complete new inlet manifold set fitted,from cylinder head, right through to the airbox,complete with new TPS, MAP and injector.
Problem remains completely unchanged from before !
Pump has been out, was thoroughly cleaned, and replaced. That has tested out fine, flows well. holds 43psi for over half an hour static test, and is feeding healthy,like new, so is believed good.
Oil temp sensor reads fine.
I'm now thinking O2 sensor faulty.
Tried this morning- as an experiment, to replicate the offending conditions,by heating just the o2 sensor and that area of exhaust, with a hair drier, until too hot to touch, then starting the otherwise cold engine. This seems to have brought the problem - back to happening at the initial startup from cold.(Normally she starts well from cold, and the problem normally arises later in the warming up cycle). So I'm thinking - get an o2 eliminator kit.
Before I part with my swiftly diminishing redundancy money - Can anyone confirm -
does my 2013 model have the same o2 sensor setup as the later (2014-2017) models ? I can only find eliminator plug kits listed as suitable for 2014 - 2017 models!
They do look the same type of plug as my 2013, but... I really don't want to wind up 'er - indoors, buying something else - if it won't fit or function.
Here's hoping for a "Yes - it will fit and work !"
PS: Bike is standard, save for a Motad silencer - which has worked fine for 12 months.
