Default Need Help!!!!

At the beginning of the year my son was running r40 2004 edition.He had so much trouble with the rear being loose that he switched back to his MTX3.
We tried everything to make the r40 work.Now i have decided to run in the novice class.Can someone give me some help on making this car work.It seems that when the rear diff gets warm that it loses its diff action.The rear diff has light grease.Seems if you soften the rear of the care to add grip it gets loser.I'm totally lost and need help.Thanks guys.

Tell us your full setup. On asphalt with the right tires the R40 is 90% setup out the box. It should not be hard for us to help you get it right.

Try disconnecting the rear sway bar. When you say you softened up the rear, did you change the springs or shock oil. If you changed the oil then you might be bottoming out the chassis. That actually coul be happening with the softer springs too if your rear ride height is too low. Make sure that you have 2 or 2 1/2 degrees of rear toe in. If you post your entire setup like AMG suggested, it will be a lot easier to help you.

Just to let you know, bottoming out the chassis isnt that bad of a thing, at least to certain degrees. I posted a few pages ago that after replicating haras setup. My rear of my chassis had quite a bit more scraping going on than the front.

A month or two later I found more photos of haras car and underneath his chassis, I was pleasntly suprised to see the exact same thing. The rear was way more scraped than the front.

Almost to where there was none in the front and lots in the rear. Id find the picture but im too lazy. :lol

hey, quick engine tuning questions...

When I return to idle from going full speed the idle is too high and after about 2 seconds it returns back to normal. Does that mean low end is too lean or too rich?

I always thought it meant that the low end was too rich, but I had to richen the low end to fix the problem.

Lean = more air = more rev.

Richen = less air since there is more fuel = always will reduce rpm.

So if richening the low-speed fixed the problem you should be good. Another way to test if the low-speed is good is pinch the fuel line the car should rev up and die in about 3 seconds. If it does it in less time , its too lean.
