Depends on how crazy you get with accessories. The March set up I run wasn’t bad at all, but it’s only 3 pulleys and 1 bracket.
It solved the belt throwing issue on my 340 immediately. I screwed around with the stock V-belt pulleys for weeks, fine tuning the alignment, making sure all the pulleys were true, even swapped a couple out, tried a couple of different belts, ran the tension from tight to loose and everything in between, didn’t matter. Stab the throttle = toss the belt. Not sure why, I run V-belts on everything else with no issues, that 340 just hates them. Put the serpentine pulley set on, problem solved.
