Just bought a 2004 viper from a guy that bought from another lol. this one had no compression on one hole and bought it for a good price. Took it apart and found pistons were backward and it caught a rin and really messed up all the cylinders. It also was piped from what i could tell by all the melted plastic and has v force 3 reeds. My question is about the dts in the head. When i got it the dts was bolted into the frame, ya good spot for it. But the head has the extra spot that is only on the 2004 newer sleds but does not have a threaded piece in it to screw the sensor in. Do i have to get the head drilled and tapped for it. The part where it is suppose to be is just painted black and on the underside of it has a couple grooves in it. If someone can help me out would be great
 
My guess is:

-They probably destroyed the origional DCS (Detonation Control System)-equipped head.

-They grounded the DCS sensor, so it would not throw a 6 flash code on the display.

-As for drilling and tapping the non-dcs head you have right now, i do not know if there is enough material until you get into a water passage. If you are sure that the cast boss on the head that is undrilled and tapped is far enough away from a coolant passage, i would try drilling and installing the sensor.

You will need a metric tap, i am 99% sure it is a m12x1.25 pitch, it is the same thread and pitch as your tie rod ends.


I have a few pictures of a stock 04 viper dcs head somewhere on my computer. If you think these pictures would help you, let me know and i can dig for them. ( i think i had some measurements as well)

So it's a stock head and has the area(#2 DCS) in the front of the head but 'it's not drilled and tapped??

If DCS was not added to the vipers until 2004, why do you think the older heads has this casting? All of the 02/03 Vipers I though had that casting, it was just not utilized.


I wonder if Yamaha had anticipated using DCS on the Viper in 02, but had trouble or couldnt get it working with the CDI mapping or something else so they decided to keep the casting but not tap it and install a sensor....

mine has the casting but it is not drilled. The older ones did not have this boss there to drill into even as far as i am aware of
