Belt Deflection

I get dozens and dozens of tuners asking how I set my belt deflection.
The video is pretty well what I set mine like or any other sled up for good all around deflection.

A reminder that after you set the deflection you must check clutch alignment again.

With this kind of deflection I never let my engine idle too long. There are 4~5 cogs wrapped around the stub of the primary and the temperature gets high localized in that area. I'm convinced excessive idling contributes to why belts will blow about 4~5 cogs off and you hear that "puk puk puk" just before the belt incinerates.
The temperature in that localized area will change the composition of the rubber making it a harder material; eventually separation will happen....BoOm!

How tight the drive belt is between the two pulleys.

is belt deflection good or bac? my 2000 mxz 700, hte track is moving at idel. how do you change it?

[mxzxRevzone]

The deflection in the video is good.

if the track moves slightly or very slowly that is ok.

If the deflection allows the clutch to emit a squeal then that is not good and have to loosen deflection a little bit. On the formula secondary you have, refer to your owners manual, you'll need a few tools to perform deflection on that particular secondary clutch.

That belt deflection can be used for any model of any power of any brand oem, does not matter.

When you do deflection like that you are factoring out belt length variances.

If the belt is shorter or longer than spec, if you set deflection that way then it will have the correct tension regardless of variating length.

Is that good or bad???

[mxzxRevzone]

that is good.

I don't understand what belt deflection is... Can you explain?

Good vid joey. C ya on dootalk. :)

[devonlethbridge]

whats the point of belt deflection ?

[HandCmotorsports]

what do i set my deflection to? i have reverse and stuff.

[mxzxRevzone]

That is good belt deflection. If you have belt deflection like that then no matter what length of belt whether it be short or long, calibrate the deflection of the belt so you see the track slowly turn or it does not turn but needs just a bit of help with your finger to turn...you have good deflection.

thanks
