    checking valve clearances

    im having trouble keeping my valves from making noise. I went .006 on exhaust and .0025 on the intake. .004 was really loud. the bottom of the feet are in good shape, hardly any wear. can i put blue thread locker on the fastening nut? can i go smaller on the exhaust valve?

    I am having trouble getting my taillight to work. My tail light has a green and black wire. I think the green runs to the brake switch and the green runs to the power on the headlight. i dont have it grounded out, being that there are only two wires. Ive tried all different ways of tryin to wire...

    Forks are not rebounding???

    You are correct. I saw one on the ground and thought it was a knockout from an electrical box. Hopefully I can find them or ill run to the hardware store and get somethin that works. Thank you

    Forks are not rebounding???

    So Im having an issue with the shocks staying compressed. Both tubes slide freely. I have lowered the shocks 2in and installed these new fork caps. I have added 6oz of 10w fork oil. im noticing that the fork cap end goes into the end of the fork spring. I am aware that these springs are...

    Engine Knocking

    I think it was the intake valve clearences. I changed them to .0025 from .004 and retourqed the cylinder head and its all good.

    Engine Knocking

    I adjusted the valves clearence. .006 on exhaust and semi snug .004 on the intake. The camshaft chain tensioner is good, the pushrod is just flush with the end. Timing is good, idle is fine and advances correctly. Stick gettin sounds, but now its sounding more like a tapping sound. The sound...

    Engine Knocking

    what do i line the protractor up with on the stator bracket? so im prob no off a tooth cause the bike idles really well. it just makes the knocking sound and hesitates as the motor revs.

    Engine Knocking

    I got this image from Pete when i was asking him about timing. Now is the postion that i want to be at when im timing at idle? And griz are you saying the mark on the stator plate can become inaccurate when locating tdc. Im starting to remember seeing someone printing a compass with 360...

    Engine Knocking

    If im not to use the tdc plate on the stator, then how do you determine tdc? also, how will a bike run if the cam is off one tooth? do you have a visual of the degree wheel you would use for this situation? Will i get a knocking sound if the cam is off a tooth? is there something that typically...

    Engine Knocking

    I think you're right with the cam being off. I didn't realize, but I'm thinking that when I was putting the locating pin back in the cam was to the right of tdc. So ill take another look. Interesting that the knocking could be valve clearences, I would imagine clearence issues producing a diff...

    Engine Knocking

    I don't notice it as bad in neutral. I didn't knock at all last year. And it ran fine, leaked a little oil. The motor has 12k on it

    stator wire routing

    Thanks, I got it all figured out. For some reason I thought the wires ran above the sprocket? I also thought that bracket went on the shaft in front of the sprocket but realized how it went back together. Thanks for the help. Take a look at my new engine knocking thread and let me know what you...

    Engine Knocking

    So after finishing the engine rebuild and firing up the motor I am noticing a knocking sound around 2500-3000 rpms. Ill first start with what I did to the motor. Pulled the head and installed new gaskets. Pulled the valves and cleaned them up. New valve seals and a minor porting of the head...
