    Baby Bore

    Well,
    I've got the 1179cc "baby bore" kit, just 4-1 pipes, Indy filters, stock cams and heads, no problems, just rejetted a few sizes larger, runs fine and strong.

      I'm STILL waiting for my 1196 piston kit to arrive.
      Bike has K&N in the airbox and a 4 into 1 exhaust. Not sure what mods I'll do to the head (if any) while it's off.

        While we are on the subject, what is the approximate cost with this job?
        I assume a valve job and probably a new chain along with the bore and piston/rings.
        Anything else? Re-jet of course.
        I would plan to do the R&R.

        Aint even go my plates yet, already making plans. Money pits are made not born.

          My costs:
          piston kit $400
          other gaskets and seals (base, valve cover, moons, valve stem seals) $150
          machine work $160

          There's $700+ right there.
          I should (and might) do the camchain at that time. Might match the intake ports.
          Then there's my exhaust mod that will be around $400 (eventually)

              I have an 1179 kit in my bike. I am running a set of Jardine 'Spaghetti pipes", Uni foam filter in stock air box with two 1/2 inch holes drilled in it. I am using a set of 78 E carbs, with the mains increased to 140, and the pilots are 142.5 (stock).
              I paid $350 for the kit, $160 for the machine work, $100 for new clutch and clutch springs, $60 to have first and second gears undercut. A new cam chain and a complete engine gasket kit was another $100. With the new paint, and other nickle dime things it wound up costing about $800 for all that.

                    So Snow,

                    Would that be Rated "X"sive for you?

                    Even with the "PG" pretty good version, it gives me a "RISE"!

                          Yeah you don't want to polish the INLET ports on your motorbike, you need a rough(comparitively) surface that vapourizes the fuel mix a lot better. Polished inlets bead the fuel into droplets that then 'pool' at the bottom of the ports Polished OUTLET ports lessen carbon buildup because carbon won't stick to the smooth surfaces as much.

                            This inlet boot redifines the word rough to be shaped thin inside where alloy joins the rubber but don't want surfaces have it too smooth either, some sandpaper not too rough, this carb boot fits 37mm carbs to an XS head, the XS boots are alloy manifolds and the rubber is bonded solid to them, was thinking of petrolproof hose but I'm about to throw this radiator hose in a bowl of petrol outside and see what it's like in the morning, a squishy mess I bet

                              Hi pggg

                              You need another 3 mm clearence on the stock boot, or do you need to change the angle too?

                              BS38's are used on some of the XS650's. Don't know what size boots are tho..........or if will go on 1100 head.
