20K Valve Check After Riding to California and back I thought it was a good time to do some major maintenance, replace the front tire that's cupped, 8k miles (not bad) oil change, clean the K&N airfilter, and check the valve clearance. Began by removing the upper and lower faring and seat. This is also a good time to clean engine parts of dirt and build up I removed my K&N filter and soaked it in water with laundry detergent. Remove the Gas tank clamped off the gas lines. Remove the reedvalve tube, and unhook the rubber bib to get to the rear cylinder head, remove the 4 10mm valve cover bolts then lift out the valve cover, remove the pulse cam cover on the side that accesses the timing hole. Remember there are 4 valves per cylinder the 2 on each side, exhaust on the outside of the V and intake in the inside of the V the cylinder cover also tells you which piston number is which. Rear left cylinder #1, front left #2, rear right #3, front right #4. I have done this before on another post so I wont repeat myself just add things I didn't mention before. This is the rear cylinder head. I turned the crank till the timing line was lined up with #1 and both cam shaft lines pointed out, this is the compression stroke. I don't know if you can see the cam shaft lines I highlighted the lines since they are hard to see. Set the crank for Cylinder #1 Check the clearance on cylinder #1, use a .006" feeler gauge on the 2 intake if its tight, if not then move to a .007" it shouldn't fit, you will have to replace the shim if it goes past this make sure to do both of the intake valves, then go to the exhaust side start with a .012" feeler if its not tight go to a .013" if it goes past that replace the shim. Do this for each cylinder. You have to put a bend in the feeler gauges to reach in Now Cylinder #3 also on the rear side of the bike. Check the clearance on #3 If they are in spec replace the cover, use sealant on the round part of the cover gaskets. Bolt it back on. Then move to the front. Drop the oil cooler and the 2 radiators, there is a radiator sensor which must be unplugged on the left side, remove the bolt and gently side it off the upper and lower holder pins do the other side then let it drop down out of the way. Remove the oil cooler bolts and drop it down. Remove the cover then move the crank to #2 position. Check the clearance on #2 Move the crank and Check #4 All mine were in spec again!
