With all the discussion about changing the front sprocket to 13 teeth I thought I would see just exactly what the ratio's actually are. I too feel the Predator needs a little more gear ratio, but after looking at the ratio's I think I will put a 38 on the back, leaving the stock 14 on the front, this will be split between the stock (2.64 ratio) and just changing to a 13 (2.85 ratio) on the front.

Front ----------------Rear ------------ Ratio
14--------------------- 36--------------- 2.57
Stock 14 -----------37--------------- 2.64 Stock Ratio
14 ---------------------38 ---------------2.71
14----------------------39----------------2.78
14----------------------40----------------2.85
13 ---------------------36--------------- 2.77
13 ---------------------37--------------- 2.85 Most common change
13--------------------- 38--------------- 2.92
13----------------------39----------------3.00
13----------------------40-----------------3.07

Any one else notice how high geared the Predator is compared to other Sport Quads????

 

I got my 13 on today, can't wait to try it out sunday. I put padla brat sand paddles on it and thats when I noticed how tall geared it really was.
this bike has half of the bottom end of the raptor so I think gearing it down will actually increase overall performance. JMO

01 raptor stock gearing 13-40
86TRX250R stock gearing 13-39

predator stock gearing 14-37 ????? is that crazy tall gearing or what?!?


Truckracer you should come on over to Whitefield this sunday. Its just south of I-40 on #2 hwy. Lots of good fun drag racing there on sundays, people start showing up around 1 pm.

How far east of OKC is Hwy 2?

 

map

Looks like 125 miles of I-40 from the city, then it would be close to 18 miles south on hwy 2. It might be more driving than you care for tho.

Good pictures. I don't mind the drive over but tommorrow is not good for me. We are going riding today on the Canadian river and I told the wife I would help her tommorow............ [img]i/expressions/face-icon-small-sad.gif[/img]

I am now running 13-38 gearing. This thing really likes the lower gears! I've lost a little top end speed. But this thing will surprise the piped Banshee's over 100 or so yards!


Vilnrk - will you be at Atoka on the 22nd?

 

a 13 tooth sprocket is only a quick fix. the sprocket is too small. the chain needs more sprocket to turn. someone should make a 40 or 41 rear. th e smaller counter actually wants to rip the back axle forward, not spin it. also i don't think the 13 is an exact replacement
