General Discussion / Alloy Rims
« Last post by Garn on December 07, 2018, 02:32:12 AM »
Did Yamaha TX500 ever come out with alloy rims?
Mine is a USA model and definitely has chrome steel rims!

Also, what is the availability of alloy rims, don't mind if they are the mud catcher type!

Another query... Where do I get a new set of megaphone type muffler (pipes)? (TX500A 1973)

I did it the way the manual stated.  I assume TDC would be the most accurate way of doing it.  The radius of the back of the cam lobe is pretty constant so that is why the manual made it simple for everyone.

 having the cyl you are adjusting the valves on at TDC on compression will always give a true
 clearance check . remember , the cam base circle ( smallest /lowest area ) should always be facing the rocker arm
 when setting the valves it controls . are you rotating the crank 180 to bring the right cyl to TDC before setting that
 side ?

Per dave it seems they should be tdc

You are correct on setting the valves.  The manual doesn't say TDC it just says at the smallest point on the cam lobe.  I have a low vacuum problem at idle, but no vacuum leaks. I have sprayed everywhere and can't find anything.  I am going to be looking at a few things this winter.

Dailydose, thanks for your persistence regarding the new battery.
I had rigged up a secondary earth from the battery terminal to both engine and frame. It seems a little better, but not good enough!
i took battery down to a "Battery World" shop and asked them to check the "cold crank" capacity of this new battery.
The owner informed that the new battery had a defective cell and is "Kaput".

Ended up I purchased a new battery (expensive) and everything seems to be working... Blinkers, horn  now work!

Thanks
