Which CDI box are you looking at and what do you need to know? I,m using the juice box and it works good.

what do you mean by a juice box

[Tweaker 660]

Juice box is a name brand of a aftermarket CDI. I bought it from Yamaha for around $300. They all claim the same gains from what I have seen. When I put mine in I tested it against another grizzly. He already had one in and with mine out we raced a few times around 300 yards. At the end he was around 4-5 quad lengths in front and was pulling away on the top end. After installing mine I was still behind ( bigger tires ) but only by around one quad length and he was no longer pulling away on the top end. Pretty impressive results for $300.

thanks for the input

On my 05 660 the reverse light will come on when I'm driving and the engine cuts out at the same time as if I'm driving over 30kms in reverse. The engine doesn't have to be reving high either. This just started and I'm not sure where to start looking. I assume it's a short or a chafed wire. Anyone heard of this?

Ya my 700 did the same thing now mine would do it in low range,the reverse light comes on and it hits the limiter..It thinks it is in reverse.It is the reverse sensor switch.iwas told this by alot of people ..And they also told me to adjust the shift linkage slightly.On mine it is a one wire sensor located on top of the tranny pretty well in the center where the linkage goes into the tranny ,,should be about $30.00 to replace.I changed mine adjusted the linkage and works great.Hope this helps

Thanks medler, I found that sensor. I unplugged it and went for a drive and it did the same thing . So I clean the connection applied some dielectric grease and so far so good. If it does it again I will replace the sensor.

[medler]

YA you can clean them but they tend to screw up again.

I know from when I worked at a yamaha dealer that float levels were problem in the 660 grizz. The genisis engines are touchy to fuel requirements. Float levels have to be exactly correct or they suffer from lost top end or they develope the dreaded studder on steep hills.

Quads come jetted for sea level and thus are way too fat for our elevation.

Big tires (read heavy), clutch kits, most exhaust systems, storage boxes, fairings and fender flares all reduce top speed.

Typically an out of the box 660 grizz will do 97 - 100 Kmh. Jetted properly with proper float level they will do 100 - 105.

Why does mine only do like 80k....never mind it had 26's out of the box.
