I would like to know what is the mileage you did before changing the belt on your P650 ?
On the first belt I did 600 miles, on the second belt i did 650 miles.I am now on the third belt 150 miles and still good with 0.9 mm spacer....Top speed (on the speedo 61 mph. no modification)

 

1200 miles on the original belt; EPI black spring and the belt kept tight. I drive it hard, but not alot of mud.

 

2200 kms on original belt after adjusting at 300 kms and blowing dust out with compressed air every couple hundred.
No plans for a new belt yet...

 

1250 km and I just took out my last spacer yesterday. Should be good for 1800 km or so. I got 26" 589s on it and I am a big guy, so there is bound to be a little more wear on the belt. The clutch is in awesome shape. A little grooving in the very bottom of the drive clutch sheaves. Driven clutch sheaves were perfect. I hope one of these aftermarket companies get their a$$ in gear and make us a belt. It probably won't be any better, but it should be cheaper.

 

Replaced the oringinal belt at 2000 miles shimmed it at 750 and it lasted until 2000 with the stock spring's new belt went on along with EPI red/black spring, should get more out of this one........

 

Removed one shim now 2700 miles, have spare belt in case i get time to change it.

 

2020 miles, no more shims. No slipping yet unless I really push it hard. Will be changing it out in the 200-400 miles.

 

Got 100 miles on first belt.

300 miles on second

third belt has 1000 miles and squealing like big dog after being run over by car.

other than that no problems at all !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

650 Prairie stock but Jeff Davis prepped
72mph on asphalt
67mph squealing belt
69mph at Glamis Ca. on sand flats
59mph at Little Sahara st. park dunes Ok. on approx. 300 yd sand drag.
52mph same place with 40mph head wind
62mph Cinders riding area in Flagstaff AZ. at 6200ft elevationnull

 

I've got about 1000 miles on mine and not a problem or noise yet. I'm not the least bit easy on it, ride it through mud and constantly pulling trailers and vehicles with it. It runs awesome but it is a little cold natured. If I do haft to have the belt and springs replaced in the future does anyone have a clue what it costs? Have a good ride!

 

Just tore mine down yesterday and installed black spring. At 1100+ miles belt is still in spec although there are no shims left to take out. Dealer adjusted belt under warranty and must have removed all the shims at that time. I will need to replace the belt in the near future.[img]i/expressions/face-icon-small-shocked.gif[/img]
