I worked on my viper adding a rear cooler last weekend and noticed a slight bog midrange when testing it out after installing the rear cooler. I pulled the carbs and went through them twice over the weekend with the bog not getting better or worse. Monday I sent my carbs off to a buddy to go through them at his shop and run them through his tank. After getting the carbs back and going through and double checking the power valves where adjusted and working I went for a ride and still had the bog I pulled the plugs with both the middle and mag side both tan and the PTO side had little to no color. Pulled the plugs to check spark whick looked strong on all cylinders. At a idle and low rpms it feels like it is running on all 3 and wide open I am right around 8900 which is what it has turned since I bought it last spring. If I am easy on the throttle it will run up to 8000 and fall flat like it does when the tors kicks in. I ran across a post on here with a similar issue and it ended up being the throttle cable was to tight and making it drop the PTO cylinder. Which after checking my cable and loosening it and taking it for a ride on the river I thought I had found my problem. It ran perfect like when I picked it up last spring.
A group of us loaded up and headed 3.5hrs north to ride for the day yesterday and as soon as my triple hit the trail it quit firing on the PTO side unless at idle or wide open. I tried unplugging the tors while on the trail yesterday to see if it made a difference which after a ride up and down the trail I thought I was back in businesses. But as always as soon as I took off again back to running on 2.
During the week while trying to trouble shoot I had checked the ohms on the plug boot and it was right at 5k but swapped it out just in case. I am out of ideas on what to do next and getting beyond my knowledge of sleds. Anyone with similar issues in the past or any ideas on where to look next? We have another trip planned for this coming weekend and I can't be that guy again with a sick sled.
