In a way, the two have opposite effects. Less caster will make the car react quicker and the kingpin ballstud will make the car smoother and give more on power steering.

For the MR4TC? Nope, the internal drive ratio is 2.2, unless you change the size of the center pulley (I seem to remember somebody made 14T/15T options for it, but I could be wrong).

I was referring to the SD. Sorry for the confusion. I just checked Yok's site and it is 2.353.

I just got a yokomo mr-4tc and it is great but the drivetrain seems a little big stiff, is there anything that i can do to possibly loosen it up? The car won't free roll very much.

many moons ago when I ran the car I soaked the belts in wd40. I don't know if this will help your problem but it does free up the car a little.

Try using the Silent Low Friction front belt, and if you are running stock try the Silent Low friction rear belt as well. I don't recomend using the silent rear belt with mod motors. The wd-40 was used on the very first belts to break them in faster. Not needed on the new belts.

Hi guys. greetings from Malta.

Nice to see this thread resurected again.

Careful assembly should see to everything running loose. Like others have said, use the soft belts - they help.

Also ensure that the wheel hub bearings don't tighten up when you tighten up the wheel nuts. One of mine does and I have to remember not to tighten the left front up too much - and make sure I use a good nut that locks.

Also see that the belts don't touch anything, particularly the front belt.

Regards

Joe from sunny Malta.

I'm not sure if getting new belts would fix anything, when i push the car on the ground it makes a clicking noise every inch or so, but the wheels are moving and the belt is moving too. Should i just try to clean out the drivetrain, and there is probably a rock or something jamming the drivetrain in there?

Check your diff screws and make sure your whole drive train is free of dirt, especially in the rear.
