My 2018 Sport has just been dynoed with reasonable results of 70BHP at the rear wheel and 58ft/lbs of torque - OK ish, but my main concern was the feedback that the fueling was "dangerously" lean.
It has had a 1st service and shorties fitted with a remap - mileage just over 1000 miles.
I am now investigating this with the local Dynojet agent as the long term consequences could be serious.
I did contact SCS-Delta as per Issue 20 but they could not assist on such a "new bike" as the ECU had changed.
The other issue is that the bike has developed a very unpleasant vibration - mainly at 3-5K, but is throughout the rev range and it is no longer pleasing to ride - has anybody any ideas?
Finally, do we know where we stand at present with regards "Warranty" on newish bike - bought mine in October 19 - my dealer is none the wiser on anything TVS as yet. Do we have any consumer rights or is this this just a case of tough shit on a 15K purchase?
I would appreciate your thoughts as I am quickly falling out of love with my 961.
Probably tuned by factory too lean to meet Euro4, vibration could be clutch basket and/or starter ring gear on back of clutch, both best caught early before serious damage occurs.
So any news Barry ? , would like to think some goodwill would come your way on any cost concerns you have with bike , some noises are just a characteristic of the bike , be sure to tell us all of your progress
The Euro emissions, take very little consideration into engine running tolerances with regards to safety limits in many respects and relatively high temperatures can be a consequence. Your bike needs to be mapped to en-richen the fuel mix, to run cooler, a weak mixture delays combustion by a slower burning procedure being initiated and therefore this can impact on the timing process, plus cause un-burnt fuel to exit down the already open exhaust valve! But then will it meet the Euro standards needed?
Perhaps you will have to try a different combination of exhaust system to correct the issue?
Not sure how the corrective processes, kick in on the ECU and respective software on your machine, as the whole process has a domino effect on the "closed circuit" carburation and ignition process going on. Harley Davison owners have had endless problems for the same reason some bikes running so hot that owners felt vulnerable riding them, from the heat being produced from the engine, same reason weak mixtures to meet EPA/ Euro standards, all air-cooled machines are especially vulnerable.
Many riders are no no longer considering machines with all the techo-wizardry-gimmickery on them as the more sophisticated things get the more problematic things seem to become. The End-game is to get all hydro-carbon fuelled vehicle s off the road.
Monobloc carb's and a 99 for me!
Hello the EU emissions mapping was done by BMW test center and never done on air cooled engines So Eu emission policy are based on BMW Test results along with there catalistic converter that only works right at engine optimum road tempretures witch makes no difference. To global warming , and all these.EU emission rules are there to get petrol driven vehicles off the road and nothing to do with global warming its a money game ,yours Anna j
