Welcome to the site!

Sounds like the IACV is sticking or a TB issue . You cleaned the sensor or you took the IACV apart and cleaned that?

 

I cleaned the sensor and the carb completely. It is idling alot better but still a bit high and doesn't want to go in gear that well. Lots of grinding and forcing.

Refer to section 6

 

What year is your machine??

You don't have an IACV and a Carburetor

 

That I'm not sure of. I bought it used and the lady didn't know. It had been her husbands. There is a winch covering the vin location. I believe it to be a 06 but it is carberated.

 

03 to 05 are 650cc have carbon and a fuel tap on the side. Also have drum brakes on front.
06 onwards are 680 fuel injected disc brake front.
Don't rely on date of manufacture on label.

 

Thank you for the knowledge. It does have drum brakes on the front along with a carberator. Would you have any idea of what is causing the high idle issue? Along with roughness when switching gears on the column shifter.

 

Column shift your referring to, if you mean the drive neutral reverse lever the yes they can grind when shifting. If so it just means you have worn dog teeth. The upgraded replacement gear is supposed to fix but most just ride as is. Correct idle helps as does properly adjusted cable.
Rincons do have a high idle. Up around 1400rpm or so.

 

So you have a carburetor you said.. Its not a 2006 and its not a 680, its a 650 and it doesn't have an IACV. The carb models have an idle adjusting knob on the carburetor.

I would get yourself a service manual and figure out what year your machine is.

 

There is a panel on the right side just below the seat. Remove the seat and it will just snap off. Behind it you will see a black knob. Turn it to adjust the idle speed. You should use a tach off some sort to get the idle speed correct. I keep mine at about 1350. Also the panel on the left side around the gas tank and below the seat comes off and you will find the shift cable adjustment there. However like Ultratec says you should really get a Service Manual for more detailed instructions.

 

I agree with Ultratec. Not only should the IACV be lubricated, but you should also make sure that the shaft inside of the IACV is perfectly straight. (It can be easily deformed when putting the cover on over the IACV.
