I just bought a TVS and I can't find a belt guide for my set up or the spark plug gap? I will have a 2.8 upper with all billet flow idlers and aux with stock lower. What size belt will I need. I have a 74.5 gator back now. Also what will I need to gap my NGK TR6's at? 18 psi expected. Thanks for any help as I am installing it next weekend and tuning at Blankenship in may. There is not a lot of info on the TVS installs!
