    @HOTSHOT-III

    Oh fux me! On my diagram there’s no power valve servo. So it looked to me like the black earth just changed to a different brown earth curcuit. If I was more humble I’d feel pretty stupid 😀 I don’t know why they left the PV connector in the diagram. I’ve got a red and a green connector (behind the headlight) that are both unused, and they don’t show them in the diagram.

    Bulb check! Makes sense now…

    Cheers bud, always a pleasure…

    My diagram! 😐 …

    alt text

    Haynes 🙄 Wonder what else I’ve been swimming against…

    Nice diagram, is it online? I’ve got two solenoid box’s under the seat that I can’t find on any diagram. They have to be side stand cut out related, but I’d love to know for sure…

    New RR didn’t work, no headlights at all. Do the later bikes put out any AC at all, or is it just broken 🙂 …

    Edit: I forgot, I passed 40,000 miles the other day (or night) was on 14.5K when I got it a few years ago…

    Edit: Disconnected the battery to frame earth and the fuse hasn’t blown yet. I can’t get my head around wiring. It’s all a bit AC\DC 😛

      The crank just turned up. It’s a nice looking piece of kit. I’m glad I listened, for once 🙂 …

      Another topic: anyone using gel batteries? Any issues with charging? Or should it be a lead-acid only on an early 3 stator bike?
      I’m having issues with a gel battery I fitted last year. It’s holding a very small amount of charge, but when I try and charge it on a mains gel-specific charger it says it’s already fully charged. I don’t want to replace it with another gel battery only for the same thing to happen. If it’s not compatible with the early Dtr charging curcuit…

        I run a lithium battery on my DTRE. Nice and light and stores really well. Plenty of cranking amps too for the start motor!

          I appreciate that they are good, the next level. I think the Re is 3 phase and totally DC though. I think the 97 onwards may be as well. The 88-96 are AC & DC though.
          From what I’ve read overcharging can seriously fux up a battery, on a liquid acid battery it evaporates the electrolyte and you can top up. On a gel battery you can’t replace it and it deteriorated to death ☠️

          I didn’t maintain my liquid acid battery and it dries out badly. I thought it was the heat at the time. I think I need to check my stator coil outputs 🙂 or replace the regulator/rectifier with a genuine one. I tried a later RR but the lights never worked. I’m guessing it is DC only. No AC current…

            Does anyone have a genuine Yamaha Regulator Rectifier for sale?…

              Bearing puller set arrived today. £25 for 14 piece set which also has two ‘leg’ puller attachments (pun intended) that some kits don’t…

              Nice & painless as I like it! Removed the bearing in 5 mins with no marking the crank at all. Wish I’d known about these before, back when two very large flathead screwdrivers were my ‘modus operandi’ 😛 …

                    My back tyre seems to develop an ‘edge’ after a few thousand miles. Or a while, I haven’t been keeping track of mileage so much since my head stopped blowing…

                    alt text

                    The centre seems to develop a flat spot because most miles are covered upright. When I go to lean, once you leave the flat bit, there’s an edge that is not very stable feeling, it kind of shimmys before it bites. Anyone else experienced this with knobbly tyres? It’s like all of a sudden you’re on a knife edge! It doesn’t help that the tread there is deep and ‘flexy’…
                    It’s gotten to the point where I’m thinking of ‘adventure bike’ type ‘trail’ tyres. I can’t remember the last time I went off tarmac. I refuse to put 100% road tyres on tho’
                    Any recommendations for good, decent wearing tyres?…

                    Or should I just get out the angle grinder? Or learn to doughnut! ☠️

                      @SpookDog Yes bud, wheelset is still available:

                      https://www.ebay.co.uk/itm/266386635256

                      Avon TrailRiders are excellent tyres and all I ever used on all my DTRs. They're roughly 85% road/15% dirt so very sticky and fast rolling on tarmac but still good for gentle off-roading when it's bone dry.

                        Yes, the edge knobs are a bit flexible sideways, and if you are leaning over you are putting more than 1g force on them, so it makes sense that stability suffers. Increasing tyre pressure mitigates it somewhat.

                          Doesn’t help that they are now twice the depth of the centre tread.

                          I need to find a safe bit of tarmac somewhere that I can practice doughnuts. Last time I tried it was a Vespa p200 with a sidecar and an off duty PC reported me for reckless driving 👍 It was in a ‘off hours’ dead end car park by the river. So I’m a bit more cautious now…
                          I don’t think that the angle grinder will be uniform enough though 🙂 …

                          Apparently Some manufacturers are using different hardness ‘bands’ in their tyres…

                            The rear tyre on my CBR resembled a baker's rolling pin more than anything.

                              Depending on which way the pin is facing. I don’t know if that’s bad or not…

                                Rear brake stopped biting today. I had noticed it had been fading over the last few rides. It turns out that the piston is pitted at a point where it was left standing for a long while sometime in its past. Don’t have any money to replace the piston and seals at the moment, so I’m gonna have to drill & fill the pits to squeeze a few more thousand miles out of it 🙂 …

                                I would like to fit a 35mm front calliper on the rear. I have one ready to go but I had to buy a 14mm master to match it.

                                  Rear brake stopped biting today. I had noticed it had been fading over the last few rides. It turns out that the piston is pitted at a point where it was left standing for a long while sometime in its past.

                                  Rear master to reservoir outlet turned up today, at last! Strangely enough the 1/2 master has ‘settled in’ and is providing enough fluid to the 35mm front calliper that I’ve fitted to the back. Go figure!…

                                  Had to clean out the carb again today, namely water globlet in the pilot jet as usual. I don’t understand why I suffer from this so often. New petrol cap time, maybe?…

                                    @SpookDog cover the gas tank cap with electical tape, I did that as soon as I got my bike, the keyhole can leak. It's not likely someone will try to steal your gas and it's inconvenient to lock and unlock the tank every time you need to fill it up which happens too often with this thing for some reason

                                        I must admit, I have really changed my tune with the 170 kit.

                                        What I would say is, make sure the powervalve is ported flush. Genuinly mine protruded the exhaust port stock. So benefits from modding the valve even if you leave the exhaust port alone.

                                        I think the DTR is a better choice for the 170. Just because you're more likely to be utilising the benefit from the bottom end more due to the nature of the bike.

                                        TZR is more of an open stretch bike where you'll want more HP up the top end.

                                        Always Originate, Never Pirate!
