My rincon is flashing the 11 code I do not have a manual for this bike any time I get it past half throttle "--" starts flashing on the gear selector I have changed the carb with a brand new one unhooked the battery for hours at a time and tried the reset that I have found on this forum I'm at a loss Any advice would be appreciated greatly

Code 11 looks like the rear VSS (vehicle speed sensor). It's the plug on the back of the front diff. I'd pull the sensor, check it, and check the plug and wires going to it.

I will look into this when I get off of work thanks

Thanks for the help I finally got the 11 code off and the TPS set but it still wants to dog out when trying to rev and no shift in auto any ideas?

I guess I'll stick to vehicles instead of ATV I cant seem to find out why this thing wont rev past half throttle without dogging out and still cant get it to shift when in auto at a loss

Has it run ok before now? The 650's were known to have crappy cams. If your cam lobes are worn it will keep you from revving up.


Rincons are finicky machines when it comes to shifting. The speedometer working properly now? What does it do when you have it in auto and try to drive?

When it is in auto it does not shift and the speedometer does not work just shows 0 all the time but in manual it shifts with the buttons fine but after half throttle it starts fogging and wont rev

I'm going to say if the speedometer isn't working the auto mode shifting won't work. You need to fix your speedometer.


My wife's 420AT wouldn't shift until I got the speedometer working, which involved a new speed sensor.


So, you need to figure out why your speedometer isn't working (I'm guessing it's that rear speed sensor I mentioned in post #5) and get that working.


Then you can figure out the half throttle. Good chance the bike is in limp mode. Fix the speedometer than it might solve that issue as well.

Thank you I will check into it more this weekend

Is this a part that I can get at any Honda shop or will I have to look elsewhere ( Rear speed sensor)

Both, depends on how much you want to spend. OEM is almost always the way to go but some things are cheaper when bought second hand or after market. These guys here say most after market electronics are hit and miss but I have bought a couple speed sensors used that worked just fine. I would check ebay or a Honda shop near you.

Where would I find a part # I have looked online and nothing that looks the same

Did you go to ebay and type in the year & model then speed sensor? Here's link to the service manual, it should be in there if that is unsuccessful.

Rear speed sensor is part number 5 here.

I would go through the directions in the service manual that Wilbur posted before you start buying parts. There are instructions in the manual on checking components with a multimeter to see whether or not they're good.

Thanks for all the help I will comment back when I have time to check the parts before I buy any

Ok so I took this thing to the local dealer and they tell me it has compression coming back through the carb and its building pressure in the radiator but they gave me a really high quote on fixing it but said that they have no clue what it could be anyone have anything like this happen

Ok so I replaced the cam push rods lifter buckets and bearings now my bike will rev but it is still throwing the 11 code and I have tried the reset that it shows in the manual but so far cannot get it to do anything. What am I missing here please if u can help I need to get this thing going again
