Sent... Get yourself up to the New Members Area and tell us about yourself, and more about this PowerTronic doobery!

@Snakebite68 Could I bother you for the service/workshop manual for XSR125, I want to start a small project on the XSR 125 to install PowerTronic ECU but since they don't have installation manual for it having a workshop manual would save me from R&D on how to remove certain parts. Also I'm new here so saying Hi!

Sure you can (done). Go make a post in the welcome area and tell us about yourself & bikes & friends bikes... lol Not a clue about the code clearance thing. I've never actually LOOKED at the file!!!

Hi, Could I be very cheeky as a new poster & ask for a copy of the XSR125 workshop manual too please? Trying to help a mate sort her bike & could do with the process to check & clear fault codes without a scanner (if that exists, I know other makes allow it). Thanks,

The Ford is a V8 Ranger project. It sat out in the weather too much. No joke, I used muscles I forgot I had (but feel them now), and a BFH more than removing things properly. LOL. Fasteners rusted tight in their clips, etc. It's getting a carbed and cammed up 5.0 w/automatic.

Unfortunatley I can’t teach you how to read a circuit diagram in a forum, its far easier to teach this from a video or in person. Equally unfortunatley you can’t just guess where wires go either, it may well be a rectifier wire, but you need to identify the location of the rectifier first and look for the same wire there, presumably disconnected! To be 100 per cent sure you need some form of meter /Ohm meter to confirm the wire is indeed the same wire at both ends. Regretfully waiting for a V75 owner to chip in with a bit of advice is in my opinion will be a long wait, the forum is relatively quiet these days with few members posting let alone replying, there’s a few regulars like Snakebite and Drewpy and myself but If there were any V75 owners they haven’t replied to any of your previous posts either!! I think your best bet is going to be asking over on the facebook site , at least you’re going to be conversing with someone who actually has one! They should be able to help. Obviously we don’t want to see you go, but if you can let us know how you got on it would be of some help to others with a similar problem.

This might be some use... https://www.ebay.co.uk/itm/185869019073

Both wires are the same size. The rectifier is missing, I’m having a job finding one, I think one of the red wires goes to it. I’m not sure how to upload a photo from my library. Do you think any 6v rectifier would do the job? Thanks

I see, if you have two red wires, generally the thicker one will be to the battery as it carries more current. Does that help? (unless of course they are both the same thickness.) can you take a photo and post it here?

Hi, many thanks. I do have a Haynes manual but I don’t understand the wiring diagram. I’m not sure what red wire connects to the + on the battery.

Hi there Meatballs, You could do with a circuit diagram, normally there's one in the small handbook that comes with the bike when new. If you haven't got one they are on ebay Check out Yamaha V50 V75(E) Y70 V75A V90 V75 Deluxe Review Tecnical Workshop Manual Moto on eBay! others may be available. https://www.ebay.co.uk/itm/305623479133?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=CsDtD4DpSo2&sssrc=2047675&ssuid=kQkCPASITQi&widget_ver=artemis&media=COPY and then there's the good ol Haynes manual, there's always a circuit diagram in those. https://www.ebay.co.uk/itm/375504326373?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=CMx8Q1-ZTZm&sssrc=2047675&ssuid=kQkCPASITQi&widget_ver=artemis&media=COPY and finally, There is also a dedicated facebook group, which might be able to help you too. https://www.facebook.com/groups/308851953995379/media

Hi, please can a fellow owner either explain where the different battery wires go or better still, share a photo. I’ve just noticed there’s no rectifier on the bike so I’ll need to order one. At the moment I know the - goes to earth but I’m not sure where the + goes. The bike has two red and one white wire with bullet connections. thanks in advance

For the XSR 125?

I thought I'd try and get the manual myself. Yamaha directed me to speak to a local dealer. I've emailed 5 of the closest to me and no reply. I'm wondering why the runaround. I can understand wanting to push custom to dealership but, it leaves an awkward situation if they're not obliged to give the manual out. I'd be happy to pay for a haynes.. if anyone has time to pass a PDF on I'd really appreciate it.

low oil level lamp is operated by a float switch which is a press fit in the top of the oil tank.... ahhhhhh, ITS the two stroke oil tank low level warning light, I thought it was referring to the engine/gearbox oil level. My mistake.

Yes, I had to resort to disconnecting the headlight bowl. The Haynes manual explains that the low oil level lamp is operated by a float switch which is a press fit in the top of the oil tank. This is wired through the neutral switch so that when the ignition is switched on, and the machine is in neutral, the lamp comes on as a way of checking its operation. As soon as a gear is selected the lamp should go out unless the oil level is low.

Hi and thanks for replying, the negative wire from battery has a male bullet connector on the end. There is a white wire coming from the loom with a female connector. Point taken regarding posting. Thanks

Generally Yamaha 70's bikes used Black as the negative. So if your battery fell out and the cables disconnected then the red connects to the wiring loom and the black connects to a tag on the frame. So look for a bolt head or screw within the distance of the battey (lead length). The wire probably broke off at the tab so there won't be the tell tale signs of where it came from other than the eyelet tab. What I'm saying is the black wire from the battery doesn't connect back into the loom. Hope that helps to guide you. Meatballs, in future could you add a little extra to your titles, it helps other people in the future who are searching for problems related to the V75. ie. Yamaha V75 wiring problem or something similar. If you have a lots of titles called Yamaha V75, Personally, I wouldn't bother reading them all If I was using the search function.!

Me again! As I was tinkering earlier, the battery fell out and the cables got disconnected. The + is easy but what colour does the - connect to? There’s a white or a red. Also, I reconnected what I thought was the low oil warning light block, this is located near the oil tank. Once started, the horn stayed on. Slowly getting fed up! Thanks in advance

Arhh ok. Thanks Thank you

Prime. For starting after you've run dry

Not a clue... Possibly Prime? A kinda choke thing?

Hi and thanks for the reply. I will look into getting the oil pump working. One other thing, do you know what the fuel tap positions are? It shows “on” , “res” , and “pri”. It seems to start and run better when on “pri”

Thanks Neo, Given what Snakebite said about the 2 line race front setup I may well buy a different kit for the front, I find the shortest a little too short and don't want to stretch it. Thanks very much for your help.

I contacted them last night via their 'contact us' page, they replied this morning.... hi there ,Yamaha YZF1000 R Thunderace (1996-2001) OEM Standard Layout - Full Kit, Of the three hoses, all different lengths supplied, which one goes to the rear? many thanks. the reply from Wez...The shortest one is the rear. There you go.
