    [MENTION=61539]KB100RTZ[/MENTION]: I believe you have used new wheel hubs for the bike , did you transplant the bearing spacers from the old hub to the new one , if not your wheels will not turn properly and while riding you will have a sticky feeling and you wheel bearings will fail prematurely

      thanks buddy, you have been very helpful with your advice.
      Am running W8DC. Which I think is a hotter plug than W5DC. But it is a 'long' plug.
      W5DC isnt available easily.
      Should I try to gently hammer in the gap to make this one a W5DC or get a new one?

      thanks man.
      Spares are a nightmare, this isn't a very popular bike in Bangalore.

      Spares are hard to comeby. Some spares like crank case and clutch cover etc are available with a friend.

      Sent from my GT-I9001 using xBhp Connect mobile app

      thanks Bhibu.
      Block is new

      Do you mean the long metallic hollow cylinder that goes inside the hub, between the bearings at the ends?
      I did take the old ones and put them into the new hubs. Tried getting them new, but couldnt find them.

        get W5DC man you can get them from Royal enfield dealerships the old model(one spark plug/ avl engined) Thunderbird had it as standard kit and is available there for 109/- just remove the aluminium cap at the end of the plug and screw it onto the w5dc at the same placeand you are done (the 5dcs sold for for enfields normally do not have the adapter at the plug cap end)
        yes the spacer it is the metallic cyl thing

        PS: you CANNOT hammer a w8bc into a w5bc.........unless you are thor of course

            @KB 100 RTZ......Very good looking Restoration....A stock new bore takes 1,500 Kms of mild riding to set. Mak sure you adjust the Oil pump to give extra 2T oil to ensure proper lube...if you are using Pre-mix then go for 3% 2T oil ie., 30ml per liter of petrol. Keep varying RPM while riding, and choose early mornings, for setting in ride, since the cold outside temp helps to maintain the engine temp., relatively low.

                ok, will replace the plug before starting the bike again.

                Meanwhile, the local fuelcock is leaking petrol.
                And this is the 2nd new one thats turned leaky. Any suggestions?

                cheers

                  try this part code DU141228-1 i think it was for boxer, im using it on mine since a few years so far no leaks you can get it from bajaj dealerships

                  about the good things , if i dont say what need to be said (even if it isnt what most expect to hear ) nobody else will , please revert man , a friend of mine holed his piston after using hotter plugs (w160z2) , i dont want that to happen to you man ,not after this much of hardwork

                  Please forgive if my post has in some way dampened your spirits

                  one more thing do lube your rpm cable every 3-4k kms of running ,its simple just unscrew the cable from under your speedo console and just pour about 4-5ml of oil into the cable drop by drop, this will prevent the cable from rusting ,seizing up and finally shearing off

                    kb100 sahib.....please dont apologize. I said that in an almost scared tone hoping such things dont happen.
                    Your inputs have been most valuable.

                    Will look for the partcode and the plug, esp the plug.
                    Will update soon.

                    cheers

                          Hey..

                          Got the fuelcock you suggested DU141228. Has stopped the leak. Thank you for the good suggestion.

                          Didn't get the W5DC though. Will go out again today. And not started the engine since too.

                          cheers

                              Ok, will trip to the RE showroom. Checked 2-3 bike parts stores today for w5dc. No luck.

                              Anyway, fabricated a part today which i havent been able to get anywhere here. This is the black plastic piece that goes above taillamp and below seat. As you can in photo, the original one's screw holders are broken.
                              Made this from an aluminium panel used in bldg panelling and a saw . Need to paint this now.
