We have Rhino's here too!
No thats not right your getting some restriction from the carb. may need to clean it out good and possible rebuild if it's been setting for a period of time.

The guy had dealer clean carb one dealer told me that's top end it idles great would it be the main jet anybody have same model to tell me if this us top End

That may be about right. I think the top speed for the 660 and 700 Rhino is only about 42-44 MPH.

38 mph is about right for the 450. Like stated before, the 700 will hit the rev limiter in the low 40s. MSD makes the best programmer IMO.

yes there is nothing wrong with it actually 38 is in the high end for a 450 my 660 toped out at 41-42 when i got it get you a dynatek cdi box gave me 10mph on top end never really need it but it is there when you do

Wow! I'm socked I thought you could get atleast 45MPH out of the 450 and more out of the 660?

[grizzguy307]

nope had a 450 for a short time before i got my 660. they are not fast but i didnt buy it to race. its awesome everywhere else tho! none of my buddies can follow me. it even pulls better in the mud than my grizzly!

[hotscrape]

Should have my dynatech cdi and coil Friday will post how it changes machine. thanks guys great fourm wish there was more rhino fans like the grizz forum keep it going.

[hotscrape]

Well i installed my dynatek cdi and coil tonight for 260 dollars not to impressed seems it's little more snappy but no extra top end just does 39 with out rev limiter kicking in basically.some people say gained 5mph to 10mph I don't see it.for the money could of bought diff accessories have not had it out in mud or climbing maybe that's where the power band will show. Hopefully don't wreck my engine dynatek says shouldn't have no problems.

All it really does is remove the limiters. All motors are different and some will have more power so when the limiters are removed it will unleash the full power of the machine on top end. If your motor is already at it's limits with the CDI then you won't see any change.

[grizzguy307]

i dont see how you didnt get any more on top end it made a bigg difference with mine

hotscrape, don't expect the 450 to be a speed demon.Like Grizzly07 stated 38 is about right for a 450. The 450 is like a little tow truck with its low gearing and will out pull some bigger displacment bikes. Check out the Rhino vids.
