Trailmaster TM38

[Moracing15]

I have a Trailmaster TM38 and the suspension is a little soft for me. I'm 194lbs and I believe it is set up for someone around 175lbs. I've done what I can with the adjustments but it's still too soft. Does anyone know what bike these forks cross with. I think I need nee springs.

1. Have you tried a thicker and high-quality fork oil?
2. What about making some preload spacers, either with washers or PVC?
3. Pull out a spring and measure coil thickness, ID, OD, and overall length. Then contact the below to see of they can match you up:

Tom is right about the fork oil. Go with a heavier oil like Motul 15W
THat alone will probably solve the problem. But you can get spacers from Joe Henner if you want to. He makes them for the Templar, and I am pretty sure that those same exact KKE fork tubes are on the TM38.

Thank you guys. I will try the fork oil first and go from there.

You guys happen to know about how much oil I'll need to get? Sorry I've been out of the game for about 30 years.

Put back in whatever you drain out. Best would be to have a precise measuring container.

Putting back in what you drain out does not always work. I have dumped forks that had 400cc in one side and 50cc in the other.

Generally about 250cc per side is about right on the 125cc-250cc level bikes.

One liter bottle will cover it, with some to spare. Measure what comes out when you pour off the original fork oil.
