Hey, well i plan on adjusting my valves tomorrow and i watched a how to video, i think he said to torque the bolt back on at 7 pounds. My friends torque wrench starts at 10 i think. So is there anything i can do about this? And anything i should be careful with when i try adjusting them tomorrow?

Yes get the proper torque wrench for the job. Get a torque wrench in the 0-100/120 (can't remember the top of the range) inch pound range. It should be a 1/4" drive. And torque to 84 inch pounds.

To convert foot pounds to inch pounds multiple the foot pounds by 12
To convert inch pounds to foot pounds divide inch pounds by 12

Now when you talk about newtons well your gonna have to google that conversion.

Alternatively, just "snug" the nuts gently.

No offense Luis, but newbies don't understand what "snug" is until they have tried a torque wrench and then loosened again with a normal wrench. Get the proper torque wrench and use it. Your bike will thank you for it. Some jobs absolutely require one anyway so you will always have a use for it.

The snug the nut sounds good, but yeah, you are right Buickguy. I would much rather use a torque wrench :)

That's the tank vent. If gas is dripping out of it, either the tank is too full or the fuel sloshed over it when you moved it.

YOU DO NOT WANT TO BLOCK THAT OFF!!!
If you do, you will have problems.
What you want is a tube to run from that nipple to the cluster of tubes of the right side near the passenger peg.
You may have one already but its not attached or you mat need to add one.

By the way, that was Duckster who gave you the advice about the torque wrench. I relish the compliment in being compared to Duckster but feel bad for him being confused with me.

Be careful that they don't turn out of adjustment when you tighten the little nut. Check the clearance again after you get them tight and readjust any that slipped while you tightened.

It's normal for the values to be a smidge louder afterwards, but knocking sounds seem strange. :3 Are you certain that you had the flywheel in the right positions when adjusting? If the piston is touching one of the valves, it could cause serious damage.

One way to check that you are on the compression stroke (when the valves are shut) is to have the spark plug out and a finger over the plug hole and feel the pressure build.

Well I couldnt get that cap off the hole where im supposed to see the "T" marks, so my friend brought up the spark plug thing. Bike seems better than before, it had a small ticking sound before the valve adjustment, nothing now besides the chain and headlight. I'm still waiting to get a new chain, no money yet.
