I've been hit by the dreaded dead TPS issue. After a good soaking in a race a couple of weeks ago, the TPS is failing: reporting 10-15% opening at idle and up to around 10-15% actual position, then 0% right up till 100% is reached when it reports 100% again. I've swapped out the TPS from my spare bike so I can keep racing, but as expected, when I called Huskysport, the only OE part is an entire throttle body at £467! I'm sure the TE630 isn't the ONLY engine in the world using that throttle body nor even the only throttle body using that specific sensor. Has anyone had any luck in sourcing a replacement without having to replace the whole throttle body assembly?
Might be able to help you out.After much research it looks like a tps from a suzuki bandit 1250 is the same. I've got one coming so haven't been able to fully confirm it yet.
It looks like the TPS from the Yamaha YZF125R is also the same part. I have one in my hand (see photos) and I'll try plugging it in and testing soon (got a busy few days ahead and a holiday starting on Wednesday, so it might not be for a week or so) From some Yamaha documentation, I believe it is also used on the YW125 Zuma scooter, but I've not actually seen the part to confirm it is identical. From my research, there is only one MAQS module that Mikuni make, so if an engine uses MAQS then it should be the same unit no matter the bike, spec or engine size, but it'll take a lot of digging to confirm this. Checking the parts fiche for Yamaha, it looks like the throttlebody and MAQS is a complete assembly there too.
The one on the 2009-2013 Yamaha Zuma 125 has the plug coming out at right angles to the unit,different to the yzf.The one in your pics is that listed as a separate unit?
The Zuma parts fiche shows a TB and plug that looks very similar: http://www.cheapcycleparts.com/oem-parts/yamaha/2012/yw125bb-zuma-125-black/intake Looking at the fiche for the YZFR125 looks like it's all one unit too http://www.yamahascooterspares.co.u...ageID=8&m=YAMAHA YZFR125 INTAKE&uid=595097853
Same unit I think, it looks like it's just the plug that's at 90 degrees rather than the socket. Worth looking to confirm Add the Yamaha YBR125 as a potential candidate too. http://www.ebay.co.uk/itm/Yamaha-YB...d=100033&prg=7839&rk=1&rkt=2&sd=280836470794&
Got back from France last night, went over to the workshop today to so some work on the bike ahead of the Centennial Rally that I'm competing in, in a couple of weeks ( http://bigbikerallychallenge.co.uk/content/centennial-rally ) While I was there, I swapped out the MAQS with the YZF125 item I got on eBay. It fitted fine, the bike fired up fine and iBeat reported no issues and all settings and measurements appear to be as they should be. It looks like it's certainly a viable candidate for replacement.
Here's the sensor if you need one. I'm convinced that the Mikuni system TPS is the same on several (all?) models. Tempted to buy one as a spare... http://www.ebay.com/itm/331671564132?_trksid=p2060353.m1438.l2649&ssPageName=STRK:MEBIDX:IT (For future viewers, this is an ebay listing for a Mikuni TPS for Yamaha YBR125 YZF125 WR125/X YW125 ZUMA, Suzuki Bandit 1250. Very good pics in listing convince me it's the same part as ours) .
I did eventually grab a 2008 Bandit 1250 TPS off Ebay for $40 to have a spare. Drilled some holes and mounted it to a block of pvc to keep the locator pin from getting broken.
Bought a 125yzf tps, don't now the year but it does not work. The output volts are lower, don't know the correct numbers but it's something like 600mV at 100% throttle on the YZF TPS and something like 800mV on the OEM at 100% throttle... No chance to get it work correct
