I have an 04 650 that i just put 26-12-12 & 26-10-12 Mud Lites on and am wondering what kind of tire pressures you guys are using and what kind of riding you do.

These are an awesome looking tire on the type 5 aluminum wheels! It sure changed the way the machine looks and tomorrow i will find out how it runs with them.I also just put in the Dynatek CDI to offset any kind of differences in tire weight.

Anyway if you guys could tell me what kind of riding you do and what kind of tire pressures you use or have tried i would grealy appreciate it.

 

Trails that I ride are generally rocky, roots, logs, and soft dirt and I have found that I like about 4.75 psi in both the front and rear. I have read that some people ride with about 3.5 psi, I tried that but did not like the ride. I know with 4.75 psi my 26" lites only measure up to 25 1/8" high. Also I have noticed that they are wearing more in the center of the tire than the edges with the 4.75 psi, maybe I will try 4.25 psi for awhile.

 

I run 4 psi all the way around and find it to be good. I was running closer to 5 psi, but found the ride to rough w/ the 6 ply tires and the SRA on the P650.

 

is a dynatek cdi necesary when you change tires?why? and how much does it cost?im thinking of mudlites for ac 650.26in. tires [img]i/expressions/face-icon-small-confused.gif[/img]

 

I run about 4.5-5.0 on my king quad 300. about 800 lbs total with me on. Under 4.0 lbs and the tires really seem to be kinda softish. Ive actually tried them at 7.0 and they still ride pretty decent. But for most stuff about 5.0

 

Dynatech CDI is not necessary. However, you will notice a small drop in performance when you switch tires, as the Mudlites are heavier than stock tires. I believe that proper spring tension, in the clutches, is more important with larger tires. You want to be sure that the secondary clutch is grabbing the belt tightly. I am not familiar with the secondary clutch on the AC650, but on my '03 Prairie 650, I found that the EPI Black Spring in my secondary clutch helped to eliminate belt slipping. This is important w/ the larger tires. Do not get me wrong, I have the Dynatech CDI and love it. The power gains are very noticeable. I am just saying that it is not mandatory to get an aftermarket CDI unit, or module, just because you install 26" Mudlites on your ride.

Have a good one![img]i/expressions/face-icon-small-smile.gif[/img]

 

adirondak thanks for info.that dynatech cdi sounds real nice.

 

Spikeland,

Not a problem! As for the Dynatech CDI. The first one I got caused engine kickback. I sent it back and they replaced it right away and overnight airmailed me a replacement. This one has been trouble free and the power is fantastic. With an EPI black spring in my secondary clutch, and an EPI red in my primary, my '03 P650 will literally flip itself over if you nail the throttle from a dead stop on pavement. That is in high range by the way!
