I leave what upgrades and updates to a trusted trans shop and discuss with them what and why. Not much experience with the 200R, I think Monster sells 3 levels and while the base is probably fine I would go for a level II with some of the performance upgrades and strengthening of the orig trans along with a mid range stall TC. Much of what I talk about above relates to the 200C, much more clearancing or possibly cutting/fabbing must be done for a 2004R. Don’t know how linkages, console etc would fit. Be aware the Roto5 has fixed yoke on the output shaft while the 200C and 2004R have a splined slip output shaft so your old shaft must be converted. If you use the orig DS you must then lock in the center bearing since the rubber bushing it sits in just rides loose in the bracket. My understanding is they glue it with silicon! If you build a new shaft the center bearing should be a locked in setup. Regardless of what the switch is, it’s lots of work to go non-stock. I’ll dig up some pics.
