    Vespa with a sidecar doing donuts? ROFL

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

    ??? It’s real fuxin easy as long as you don’t try and turn left while you’re doing it, work it out 😉 …

    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. Accidentally, I broke off the plastic fitting that the reservoir tube fits on to. Once I have the pennies for that I’ll get on with this long overdue upgrade. My rear brake makes up well over 50% of my braking, so it’s needed…

      I have some ideas for a front disc upgrade, but I need to find someone who has access to ‘water cut’ a disc centre that matches a Dtr hub to a suitable sized ‘floating disc’ outer…

      Edit: reservoir tube in post…
      Need to test charging coil output to see why the bike is eating batteries. If output is good from coil replace regulator (long overdue) with used part…

        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.

                    Sorry for tardy reply, yes it is £155 posted.

                    Are all 170 Athenas fitted with an o-ring head? Or are some fitted with a gasket?…

                    Yeah, it’s going to live on the Dtr…

                      Can anyone please let me know where I can get head gaskets for the 170 top end?
                      Also if there are o-ring upgrades?..
                      Ta!

                        PJME. Never needed an O-Ring upgrade. I've not had any issues with the head gaskets for my 170 kit.

                          @SpookDog All Athena kits i've seen are with gasket. The o ring head is custom.
                          I 'm not fan of this type of sealant for a combastion chamber,good only for competition with frequent rebuilds.

                            @MadGyver The O-Ring sits between the skull-cap and head cylinder head.

                              @Calum I thought he meant the o-ring groove they do on cylinder head for replacing the gasket with o-ring.

                                Ah right. No, I didn't realise that the Athena kit used an O Ring for the above and consequently it leaked coolant 🤣

                                    I’ve been getting a niggle the last few days. When I fitted a new pilot jet a month or three ago the rev pickup was so much improved that my little bike was actually popping unintentional little wheelies when I was pulling away, even cold. Just lately it’s been getting unresponsive, you can hear the ‘bore noise’ from the carb without the engine picking up. If that makes sense?
                                    Any ideas wtf it’s caused by?
                                    I’ve been getting crap in the carb problems forever, usually it’s the pilot that gets affected. Does this sound like main jet obstruction?

                                    Any help, Yada ~ yada…

                                      My Cagiva is running like shit at the moment.

                                      Built that engine the summer and it was legit rapid. Went to Belgium a few weeks ago and come back and the bike ran so bad. Spent the last two weekends jetting it. It can't be the fuel since that's the same before I went to Belgium, however the temperature has dropped...

                                          It’s a weird one! I cleaned the carb out again. Another tiny little bead of shitty/water in the bottom of the bowl. Not even half a match head. Less than usual.
                                          This time I junked the air filter because it was starting to disintegrate. I thought I had a good NOS one but that was crumbling as well! It’s definitely running and picking up a lot better without the old filter. Seems it’s down to the fact that it really doesn’t like the damp atmosphere this weather is making. Way too humid…
                                          Too much rain! I didn’t even consider a low pressure atmosphere!…

                                          It used to really love the cool dry early 5o’clock morning air a few months ago! You could really feel the extra whump to each charge of mixture. Especially at low rpms…
