Hi all,
Iam a Dutchman living in Brazil since 2 years now. I recently bought a 2007 MT01 here in Brazil with 10.000 km on it.
This bike is really rare here, only about 85 are sold here in Brazil. So it's difficult to find knowledge about this bike here too..
Now i have a problem with the bike. Sometimes it runs great for a long time, but sometimes it starts to "stutter" real bad. When this happens it also wants to turn off at traffic lights, and its difficult to turn back on.
But then the next day it sometimes will run great again. Actually every time i took te bike to my mechanic it runned great again so for him its difficult to find the problem.
He allready did all the maintainence according the service manual (10.000 km), including cleaning of the injection. After this it runned great voor about 175 km but then the problem showed up again.
Does anyone here recognises this problem, or have any idea where we can search for the problem this bike has?
Hi, firstly, at 10000km it hasnt even reached 1st service (20000). But its been around a while. I wonder if it has had the tps replaced under warranty as thats what it sounds like.
DONT let anyone go changing the idle screw settings. Contact a yamaha dealer who can look it up for you maybe.
The tps can be checked with a multimeter but it is a little fiddly to get to. Its on the exhaust side behind the engine cover.
Not an expensive item. Dont go fiddling with everything else!
See what others here say but I would reckon thats your first thing to check.
Id probabaly go with TPS as first port of call too..
There was a recall from Yamaha for these. You should also be able to check with Yamaha using the frame/VIN cross referenced with their data base ( ie- they will look it up )
They do still go bad, even the new ones. However, I would anticipate that it take use to cause wear, to produce the brass dust that starts to build up and cause contact and signal breakdown ( often exacerbated by heat) which leads to the problem seemingly fixed after a reset and/or when the bike is cold.
I would agree with everything Graeme has said vis a vis fiddling with the TB set-up.
Good luck with it. If you wrench on bikes at all, you'll not find the work too difficult. It needs set-up but this possible using the bikes OBD Diag interface. And some disasembly to get access is all...
Just to add - there is a Dutch forum that is quite active. Im sure you can find alot of detail available in your mother tongue, if that appeals to you...!?

Thanks a lot for helping!
Both the Dutch and the Brazilian service manual have services listed on 1k, 10k, 20k etc. (every 10k). But for this case that doesnt really mather i think. What i know is that the bike has been stored for several years.
I passed your sugestion about the TPS sensor on to my mechanic, and also told him to leave the ajustments of the injection untouched.
In case they need to replace this sensor, is this an universel part, or has each brand/model a specific sensor?

You too thanks for helping.
Good to read that you confirm the things segusted by Graeme.
I tried to register on the Dutch forum earlyer, but no respond so far.. Seems a little dead there unfortunatily. Also there's a German forum Donnermeister but English is easyer to read then German for me.
There is an English speaking sub-forum on Donnermeister too...
Since FaceBook grew to be a monster, forums have suffered a quiet and silent death, and largely migrated to that platform.....
Progress huh !>/?

That English speaking sub-forum is nice to know, i will have a look now end then there!
When i deleted my profile on facebook some time ago i saw that as progress in my life
But for this kind of stuff facebook servess well actually
Looks like my problem is solved!
The mechanic has checked the TPS but that one seemed to be allright.
Even though the (iridium) spark plugs looked oke, we decided to replace them.
Yesterday i made a trip of 450 km, and the bike runs great!
No idea why thos sparkplugs were bad allready. I assume new in 2007 they didnt use iridum yet, so that was probably the 2nd set already.
Anyway iam happy that the bike runs great now after this simple fix.
The people i ride with here have supersport bikes, they like to go a little faster on the highway.
Above 120 km/h a little more wind protection would be more comfortable.
Are there windscreens that make a lot of difference on the MT01?
In the twisties its bye bye to the supersports

Thats fantastic, really good to hear. Dont bother with iridium, no benefit at all.
Secdem screens, works well at cutting that high speed blast, look good too. Go the shorter option.
Tested at Phillip Island!
Great news and good to know the iridium were the the problem I might change mine out but they're supposed to last 100000 miles ffs maybe the big twin just doesn't like them
Not sure if this can influence the wear of the spark plugs, but here in Brasil the quality of the fuel can be pretty bad..
