Hi guys

I have a R33 GTS25t s1 which i bought a while back. A previous owner decided it'd be a really good idea to unplug the throttle position sensor and cut the wire out of the loom....I know, stupid, I have been told that 'apparently' the RB goes harder if it doesn't know where the throttle is.... :) WTF do these people smoke?

Basically it runs perfect except sometimes at idle it revs up and down, up and down etc until either I tap the throttle slightly, or it stalls itself, really really annoying. Now my brother being an electrical engineer has the necesary skills to rewire this...except we cannot find on the loom where it goes! No sign of the old wire anywhere. Any help, advice, photos would be HUGELY appreciated, this is really f***ing me off!!

Thanks guys,

Rhys

Anybody have any ideas?

Right i have an idea for ya.....

I assume ur looking at the plug located up at the throttle housing, this plug has wires cut, mine too. i discovered that it was probably for the air mass meter newly located just after the air filter. the wires have been cut and a new loom added down near the air filter with an aftermarket mass meter.

I think ul find the throttle position sensor still located just behind the plug underneith the throttle housing with wires still attached.....

I had the problem with the rising and lowering revs, on mine this was caused by a build up of crap on the butterfly valve. just take off the ally pope to the throttle body and clean the valve and u should be running like new again........

Had a look at the throttle body, seemed fine, but gave it a clean anyway, its still not idling right tho.

Can't see any sort of aftermarket sensors on mine

What do you mean by a mass meter? Similar to air flow meter? Mine's still using standard air flow meter

      I've owned a few scooters over the years, a Vespa PX oil burner was my first scooter, followed by a few others, including a little 50cc BeeWee that I used as a barracks bike, and I've had a blast on all of them, they really are the cheapest for of city/suburb transport around The only issue with scooters in Australia is lots of people look down on them due to their size,  maybe they need a big bike to make up for something else where they are lacking, unlike Europe and Asia where every man an their dog owns one, and now that filtering is legal in NSW, local traffic is never a issue Not to say I haven't owned my share of big cc bikes over the years, but they were for more blasting through the hills or Hwy riding where it needed to sit on Hwy speeds Safety wise, I ride like everyone is always trying to kill me, everyone is running a red, or running stop/give way signs, or generally asleep at the wheel, which most people are duringtheir commute, I also ride really safe, and give myself, and everyone else enough room in case I need to pull some hasty evasive actions, I've done a few rider training days over the years, which has come in handy on more than a few occasions  As for mods, there's nothing really, and yes your right about aftermarket exhaust, all you get is loud and obnoxious noises from them, like every 250-300 cc you hear with a aftermarket muffler, in saying this I did put a rear muffler from a 125 Aprilla on one of my old 125 scooters, it was horrendous and no amount of full face helmet and ear plugs would dampen that noise As for coming from the Harley, and what a overpriced POS that was, I no longer do big rides as my poor old busted joints ache after about 1/2 an hour of riding, long cruises are so much more enjoyable now in a car, so a big bike would be pointless

      Oh wow, it's easy to forget how cheap these can be. Probably the cheapest way to travel. Though people in cars here tend to be morons and I would not feel very safe. Were scooters ever big in Australia? It used to be the thing growing up in Europe ~20 years ago. 50/70/125ccm Peugeot or Yamaha and some others. Utterly obnoxious Polini race exhausts. Kick stands that slant as much as possible. So loud. So much noise for really not moving very fast at all. But it felt cool at the time. Not sure where I'm going with this, but there is an aftermarket for mopeds! Though I'd have pictured you more for a Goldwing kind of guy after growing out of the Harley.

      As the MX5 isn't apparently "manly" enough, and I need something for runs to the local shops, and also take to my part time job at the salon, basically I can keep the MX5 away from car parks and stuff......like "flying lockers", I was wondering what I could buy to fix this issue LOL, I pick up a new Yamaha 125 Delight this arvo from Trooper Lu, basically a R1 that you can fit a slab of beer on between your feet, also, it was $29400 cheaper than a R1, so actually it's 2 x better than a R1
