Im looking for a "slow" (1/4 turn) twist throttle for a 660 raptor. Anyone know which throttle is 1/4 turn? Is motion pro the best, economical choice for a trail quad?

 

A 1/4 turn would be 90 degrees, and would be the fastest twist you can buy, not slow. And its definately now what you would want on a trail machine. Go with a 120 degree turbo for your bike, the rest (cr/cr pro/etc) are all around 180 degrees which would be a half turn.

I guess the 120* TURBO sounds like a good choice. 180* would be too slow and I would probably have problems going WOT from a start. The 90* would be too sensitive for trail riding as well, so 120 it is. Thanks!

 

The turbo is way to fast, you'll be going to WOT in about an 1/8 of a turn. I have the CR or CR Pro and it's still a little to fast 1/4 turn at most. The 1/4 and half turn is rated for a carb that needs more throw to open.

 

Ok, so Im confused [img]i/expressions/face-icon-small-confused.gif[/img] what throttle will I need if I want a bit more than 1/4 turn?

 

The CR Pro will be about as close as you can get to a 1/4 turn. The Vortex would be about an 1/8 turn and the Turbo would be just a little more then 1/8 of a turn. The last 2 would be way to touchy.

 

so nothing can give me MORE than 1/4 ? [img]i/expressions/face-icon-small-sad.gif[/img]

BTW, I just got a HC Stage 2 and need the springs, any good place to get them from? MR has them for $135 and I havent found anything on ebay.

 

You wouldn't want to go much more then a 1/4 turn. I just took off my twist throttle because where I moved to is mostly tight trails and so I can let others ride my quad. If you want to try it I'll send you mine.

 

The push pull is rated at approximately the same speed as the cr and I've got to choke up on the throttle just to get close to finding WOT on a full half revolution. When I tried a CR out on a stock bike it was about 120 degrees of rotation (rated at 180).

Read the info on the Motion pro site. Notice where it says the cr pro is the slowest turning throttle they offer.

maddog was that on a raptor with stock carbs?

The rate is what you need to look at when trying to figure out how much twist a throttle will actually have not the listed degrees of twist.

This is what I got with my raptor with stock carbs (24mm travel):
Motion Pro CR Comp which has a rate of 2.35 (rate is degrees of twist to pull/travel 1mm)
It takes 57* of twist to go from idle to full throttle (I measured it) which matches to the listed rate (2.35x24mm=56.4)

The CR Pro would be 2.95x24mm=70.8*
The Turbo would be very close to the Comp 2.30x24mm=55.2*
The push pull is 3.67x24mm=88*

I would get the CR Pro if I were to buy one now the Comp is a little to fast.
