    Rebuilding motorcycle after timing chain skip 62K Km

    New pistons fitted with new piston rings are now into the new cylinder block. "Somebody", including me, machinist who reamed the seat or whoever, scratched the cylinder head. The marks are comparable with the marks left by the MLS gasket, no lips visible. Now thinking if I need to dress the head...

    Rebuilding motorcycle after timing chain skip 62K Km

    In this version of events I left the conrods on the crankshaft to avoid splitting the crankcase. I can install one circlip and the piston rings on the table, then the pistons go into the barrel and I lower the barrel to fit the gudgeon pins and the second circlip for each piston. I need three...

    Rebuilding motorcycle after timing chain skip 62K Km

    It moved into the garage, cupboards and boxes :). I built myself worksheets and instructions:). With pictures and hand notes. But the most annoying is that the bolts and nuts are together…

    For info the manufacturing orientation of the circlips securing gudgeon pins. It should be possible to slide in the gudgeons through the bottom scallops of the barrels. I am not sure how to fit the circlips though, it will be a narrow space and fingers are not pliers. Thimbles, custom made...

    Lube the splines...

    Thorough degreasing and cleaning before applying MoS paste is important. And not just smear it, rub both parts patiently with a soft toothbrush. The idea is to push the molly inside the micropores and well on the surface. Make-up is not effective, regardless of how much molly you paint with...

    Lube the splines...

    Swinging arm is so full of holes it's impossible to keep the shaft clean. Cleaning and lubing from time to time seems to be a good idea. On the other hand, I never lubed in it 62K Km. This is the first time I see it. Looks like it could use a bath...

    Gave the robots some work to do while waiting for the piston ring compressor sleeve.

    Bike wouldn’t start 2020 GT

    Sometimes it works if you turn it on, wait a second then press the starter and keep it pressed 3-5 seconds. Happened to me, reported by Boneville riders too. Folklore says it happens more often in cold weather. Folkrore also says it will usually start at the second trial. Suspicions about...

    Rebuilding motorcycle after timing chain skip 62K Km

    Long way to go. I tried to install the pistons but the tall steel band compressor I have is nor suitable for the job. I need one with the pliers. For these pistons diameters there’s no dedicated sleeve but only an adjustable tappered one which I couldn’t find in stock in Europe. Once I have the...

    Exhaust expansion and contraction noises

    I am thinking to make myself some from fibreglass reinforced hose. Winter is coming… nights are long… :)

    Exhaust expansion and contraction noises

    Rubber grommets/dampeners keeping the shields degrade fast and cut often, rattling even if all bolts are tight. Tried Kawasaki ones, same result. Tried to reinforce them, sometimes it works. Sometimes the tab does not fit inside the grommet's slit when you slide the shield back on. That may be...

    AIS - Reed Valve Location?

    It should. If you find a robust cap. The reed valves have their own gaskets buit in. Couldn’t find the box where I put my valves but found these for Speed Triple on ebay and they look the same. They seem to close when the suction is enough in the exhaust port. They are open at idle .

    AIS - Reed Valve Location?

    They are routed through the head. See the hole between the exhaust valves. The reed valves were absolutely filthy with a sort of asphalt at 62000 km. I don’t have pictures, I dropped them right into carburetor cleaner.

    Here you have the SAI reed valves on the left side of the head cover.
