Recently had a cylinder burndown on 2005 Viper Mtn. (about 350 mi on sled), which appears to have been caused by a lean burn. Do you feel a water temp gauge could have alerted me to the problem enough ahead of time to correct it before it happened? You guys that have installed gauge- any pics or suggestions at to type, manufacture, mounting, etc. Thanks!!!

I really don't think a h20 temp guage would have saved you....EGT maybe.
A h20 temo guage would still be a good idea..... waiting to hear for brand myself.

If useing EGT in a stock Viper, what is preferred location of temp pickup?

I thought the 2004/2005 Vipers had a DCS to help save this situation.

I believe the Viper S had it and the SRX had it for a year in 02 but that is all to my knowledge.

04 and up vipers had the dcs.
Was riding trail back from Dayton Safety Hut area and was watching my speed most of the way back. Meltdown occured in valley below the Overlook. Did not see the DCS light come on until just before sled died along trail. Was running 143.8 MJ because temps were warm, which according to chart should have been OK. Have been scratching my head trying to figure things out. Just don't want to have to go through the whole process again. Will run richer jets next time and keep a closer eye on plug color.
Are you sure your dcs is working properly? It should have alerted you waaaaay before a burndown, it does on my srx, in fact it's often too sensitive and therefore annoying!
Does it blink ok at startup?

143.8 mains? that is small.
That's what the charts show. And the dcs was working fine before we took it out. Could it have been a possible carb or oil pump problem?
Any pics from you guys that mounted temp gauge or egt gauge?
By the way, an identical jetted viper pulled the burndown back. Pulled the plugs from that one and they don't look lean. I know they should be checked with kill switch at speed, but it kind of indicates we may have some other problem other than jetting.

What do your plugs and piston was look like in the other cyls...if they are jetted the same...it will give you a good idea on the overall tune up.
ps...we NEED pictures of the burn down.

if you let the sled idle down for a second then the plugs will change. you really do need to do the kill switch while holding the throttle at the same time.

Find a large open part of land (Lake, field) hold the throttle wide open and after a bit, hit the kill switch and hold the throttle to the bars -as redsnake3 mentioned until you come to a stop.
Pull the plugs and look at the color and look at piston wash by your exhaust ports if you have one of the probe lights and turn the clutch to see each piston.
