The O2 sensor can only tweak the fuelling a little bit from what is saved in the map in the ECU. This is to compensate for temperature changes and altitude changes but cannot accommodate the massive change of going from blocked to unblocked intake snorkels.
My friend in China told me they have similar restrictions there as well, but what they did was simply replace the ECU with the ones mounted in the Thailand version, and with no extra modification, it goes to 94hp straight away. Don’t know whether this will work on an Australian model as well.
nice investigation process here mate. awesome to see that you've finally found where it is. did you get it derestricted at the end or you've left it stock?
Don’t switch to unrestricted intakes without a full tune! The ECU can’t compensate for that airflow, it’ll be so lean and melt your head gaskets and pistons. Tuner told me this, he had a customer do it
the U.S 650r have no restrictions with a tune and aftermarket exhaust and air filter you might get a little my power if that is what you are looking for.
The O2 can only adjust about 10% - or + in fuel amount. Not enough given how much air you're going to be introducing. Woolich does the tuning for these, and they make stupid amount of power for a LAMS approve bike (90rwhp).
hi mate, great video. i'm fully licensed and am looking at the CB650R now, absolute shame it is LAMS restricted. but, do you think it still has some pretty great up and go?
Just for anyone watching this, if you derestrict a Lams motorcycle in Australia, it's technically illegal to ride BOTH as a Lams bike(for obvious reasons) and also can't be registered as an open license bike as it's classed as modified. You actually need engineering and then re licence the bike. It can then never be put back to Lams. Just leave it as a Lams bike, ride for 2 years and buy an open bike.
I just don't get why Honda just doesn't sell the open model since midsize bikes are where the sales are going nowadays. 1000cc bike is more expensive and difficult to justify on Aussie roads by most people. Surely it was harder to source a lams specific one over just the normal one.
Yeah I did it myself using a power commander and getting new intake funnels. It has more top end power but it use alot more fuel i only get about 140kms out of a tank around town.
@@2wheelsnaked585 mate I get same amount stock bike I had a ninja 400 used to commute to work 20km a day filled up every 3 weeks or more now the 650r is a week then fill-up.
The CB650R A2 is restricted the following way: A new set of air funnels that restricts airflow by 86%, and a rewrite of the ECU to match the new air/fuel mixture. With this setup peak power (35kw) is at 10.500 rpm. The air funnels can easily be changed, and the ECU can be reset to full power. This is how Honda delivers it to the EU at least.
I'm a used car dealer in the United States. I deal with a lot of disgruntled customers who whine about this, whine about that, and just whine whine whine. Having said that, this guy has a legitimate complaint. I don't know what country he is in, but in the U.S., the dealer is essentially deputized by the state to act on behalf of the customer on the transfer of title + registration, and for the collection of taxes. If the customer trades in a vehicle, it is the responsibility of the dealer to take possession of the title which requires the pay-off of any lienholders who have claim to that title.
Yeah nah. The restrictions are moulded into the LAMS approved intake trumpets inside the air box under the tank. When remapping the ECU, you'll need to exchange the two pairs of intake funnels at the same time. The sell them (genuine Honda) from multiple sources on ebay from international sellers for about au100 the pair. The new ECU program will assume these have already been swapped out first. Put your intake guards back in buddy. They're there for a reason and that reason isn't performance related. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1V04SKdudbw.html Part # FUNNEL, AIR 17225-MJE-DB0
@@denis7738 yes funnels the part number for them at partzilla is 17225-MJE-DBO. you have to buy two of them i think thats what i did but i am still waiting for them to get here.
I've seen alot of people do with with their CBR650R's. Exact same engine.. You should see approx double the power output with the air intake mod and tune.
Yes you are right for the o2 sensor adjusts the air/fuel ratio but doesn't adjust it that much. It will only slightly adjust the fuel from its original map for things like Cold/Hot days, Humidity and Cold starts. Get the ECU flashed it's not that hard, just take the fuel tank off and its 2 plugs. For the intake you simply replace the intake runners with OEM Unrestricted ones. You should see around 75ish hp with stock pipe and with aftermarket you should see something like 85-90ish
@@saschafranziska6422 17225-MJE-DBO thats the part number ask your cloest honda dealer if youre in germany in Australia they ask for VIN number and if your bike is restricted they wont give it to ya.
@@2wheelsnaked585awesome as I'm in Melbourne too and thanks 👌 that's a small price to pay in my opinion to get the most out of the bike and remain somewhat stealthy while on LAMS.
Yes try it mate I want to buy the 650 but the restrictions on it is stopping me as might have to go for the 1000 cb but the cb 650 catches my eye more for some reason and yes been looking around to see if others have done it but can’t find no one who has only talk about ecu flash and so on
@@saschafranziska6422 you have to take it to a place that has a dyno and they will retune your ECU after the air intake thingies are changed to the full open throat ones. If you don't do this, your engine will run too hot and cook itself from the inside out.... lol
Good video, would recommend a better noise cancelling mic to pick up less road noise and more of your voice. As for the fuel economy, you're getting around 31-32MPG from the numbers you gave, which is pretty typical for a 649cc inline-four when it's being pushed. When driven economically, you can easily get 70MPG according to reviewers.
