Losi Promoto MX, fork dead zone

More discussion gets more ideas for improvement of forks on Losi Promoto MX. Thanks to Jeff and Tim for their feedback on this topic. The dead zone on the forks can cause zero movement of the front suspension, and an unstable bike. Unstable equals less predictable and more difficult to control.

This great video is so helpful for me to adjust the preload of the front suspension. Much appreciated! 👍👍

I didn't want to loose the ride height and lean angle on mine but you are right about the dead zone although it should disappear one the emulsion is fully mixed each run. I cut some soft sealed cell foam to put in under the bottom cap this has allowed me to fully fill like a diaphragm shock. I used a good quality kneeling mat and an 8mm die cutter to make slugs about 10mm long.

Do you have a video or post somewhere of your mod?

[@G3516dude]

Excellent video, I’m going to do this to mine when I service the forks.👍🏻

So 1 old man 2 the other old man! I raced motoX for 40 years? I been looking for someone that finely seeing what i seen. (the air in the forks) I'm glad to find you and your mods to the forks. So to make sure what you're proposing is, your limiting 10 mm of travel in the forks ability? right? and doing so your keeping the piston in the oil bath and keeping the piston out of the air? so to make sure, your limiting the travel, and you haven't seen any other side effect from a shorter travel. i only question this, is i cant emegin shorting the travel on a full size bike. but understand there are benefit to your mod. ps. i thought i was nuts asking this, your the only person that seeing this. thanks for all your determination finding a fixing this issue losi had to know about. Have Fun Sorry i wrote a letter. ADHD issues.

Keep tappin' that throttle. Bad rear wheel bearing was why I kept having chain tension problems.

Forks on a mx bike have a shim stack on each side of the "piston" and a bleeder valve on top of fork to remove air after every ride. Bladder is for the nitrogen in rear shocks. I still love your tip. Plan to do it to mine. Have you done the brake mods? I loved those changes to mine.

[@readeracingRC]

SO a bladder in the forks would solve the whole issus. instead of shorting the fork travel? my 2 cen have fun

[@gmummy]

Thoughts on nitro fuel tubing as a limiter?

[@RCCAPERS]

Where did you get the sandpit rc tough block?

[@philip-sancho]

What is that sleeve made of? What dimensions?
