My friend has a 03 viper mountain it has 1300 miles on it. Last week he took it out for the first time. He said it would not go over 70 so we lined up and I waxed him with a sxr 600. We got it back and started looking it over. Found the sec was stiff tore it down. Found rust witch wasted the bushing cleaned and relaced that and still was ruff opening. Then we found it was rubbing. We where told it was warped or a bad mold. Did any one else have this problem? Or was there a recall

Did you replace both bushings, or just the in the helix.
yeah we did both bushing and new buttons and still binding up hard
Sometimes the new bushings are a little tight and need to break in. I have only seen this on Vipers, but the secondary clutches are all the same in that era. Don't know if there was a bad batch of them or not.

Secondary Clutch
Maintenance and replacement of bushings and other wear items will always be there.
I installed a Shockwave secondary helix setup last year on my 2004 MNT Viper thats modded up. I like it. Works great. My buddy is a Yamaha dealer and sells quite a few and runs them himself on his modded up MM (944 and 980 UB motors) and on Aprex/Nitro turbos too. Easy to install, easy to setup and adjust. If you need more adjsustment , there is another setup for the next helix ramp angle range setup.
