Cheapest DIY Servo Bypass

Pulled out that hunk of a servo motor today, went to the drawer and pulled out a 10K resistor, plugged it in and wrapped it up. No light and I'm a happy camper. Great mod!

Another success story for the el-cheapo bypass. I had 2 5.6K Ohm resistors sitting around and stuck them in the connector: no FI error and all is fine.

Another happy "customer" for the resister-mod. I used a 1/4w 10k resister.

Thanks for the effort.

I mucked around with my circuit board and even produced two lovely examples of the mod from the diagrams on this site. Neither worked because I must have rushed something or suffered poor soldering. Didn't matter - I enjoyed myself doing the DIY and then just rammed a resistor in the socket and got on with the riding.

There clearly is a wide range of resistances that will suffice, as others here have mentioned. For example, we know that 10,000 ohms works as attested to by many, but the range actually goes pretty low. The OP's picture shows 2 resistors in parallel. By the color bands (Orange-White-Red) these are 3.9k ohms. Resistors in series add while resistors in parallel divide. So two 3.9k resistors in parallel (as shown in the original post) would give you 1950 ohms.

Someone who has a Grave's unit (not me 'cause I'm too cheap) should use an ohm meter to check the two pins in question and see what resistance they're using.

whats the reason to remove the Servo, and also what is the Exup?

Exup is a "valve" in the downtube/header of the exhaust.
The servo operates this.

You can disable the exup, and still have the servie in place, but by doing this servo-mod you can remove the weight and bulk of the servomotor.

Hey guys so I removed the servo just now. Went to radio shack and got couple resistors. They only had 10k 1/2 watt. And 4.7k and 3.9k resistors. So I can run a single ok or 1 4.7 and 1 3.9 . Which way to go? Does it have to be exactly 7.5k? Usually with resistors there is a range that works. I just don't want plug the wrong one and mess up my ecu or something.

morning,
so installed the 10k resistor and I think it worked, no Cell light so far. is there a way to check through the onboard Diag?

Yep!  Just make sure you don't start up the bike before you put the resistor in or you'll throw the code.  

What can I do if I did start the bike up before doing the mod? My CEL is on but I want to do this mod. Thanks!

Just go ahead with the mod; the CEL will go away.
