Restoration Notes on the TX-500

Oil Alternatives

The standard oil filter for bikes have been years ago. Periodically NOS show up on Ebay. Prices to have been increasing as the supply shrinks.

They typically been going $10-$15 each.

There is a kit appears to be still available some Yamaha dealers changes the filter mounting to allow the use of a still available The down side is that the filter specified is too long and you to remove the right side case to change the filter. As an a Fram 6607 (2001 V6) filter is short enough to fit on the mounting plate without the to remove the case cover. gotten email from a few and XS-500 owners who have this route

Air Filter Alternatives

I’ve not able to get TX-500 air filters. I found that a newer filter can be easily modified a spacer to used in the TX-500

Muffler Alternatives

Being to find original mufflers in shape, I picked up long cone mufflers at JC Whitney. fit nicely even using mounting brackets. While not equipment they look similar to the Yamaha originals. The modifications required are to add some for the side and center stands so don’t rattle against the new Performance seems minimally by these.

My original mufflers had the insides completely rusted out, so offered minimal back and where pretty loud. the new mufflers I think the bike have a little less low end This could be my imagination the bike is now significantly quieter.

In the Gas Tank

While I poured oil in the cylinders when I parked the 17 years ago I didn’t do much the gas tank other than it. Looking back this was a Upon starting the restoration I loose rust in the gas tank. I it several times only to it quickly clog the petcock with rust particles. some net surfing I found tank sealer.

I ordered it, followed the instructions and it to work great!

I read somewhere on the web that a 2:1 Jardine header on this was a bad idea but there were no as to why. I liked the looks and the but I found that it really the low RPM performance. After carburetor I was able to get the high end performance by significantly dropping the size of the jets, but I was never able to get the back in the 1K -3K RPM range.

In general these bikes have extra power 3K so the loss was unacceptable to me.


The following are some tricks learned over the years this and other bikes.

trying to determine correct jet size try a full throttle run the air filter removed. If the bike better, it means you’re a little too rich or your air is old and no longer breathes. If the bike worse it likely means too lean.

Note that the O rings on the jets of this bike fit snugly and seal. If they you’ll likely run too rich and get performance.

Polishing Aluminum

been using a buffing kit on a grinder from Jestco, finishing with Mother’s polish. The end result is pretty but you need to do this every 6 I was advised to seal with a coat.

I tried it and that caused dulling so I removed it and just
