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 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.
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).
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
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.
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.
@@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.
@@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
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.
@@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.
