So winter 2020 I had my 2019 600R for a season and I was not happy with the rear tunnel issues that the 19 had, and the fact that running non race gas in the R engine made it a low performer. Might as well have a 600HO I thought.
So because the 21s had EFI now, a few roundy round teams bought sleds just for the engines. I scored one of these chassis.
I sold the 2019 retro and focused on making the 21 into a RR.
My first challenge was finding a 600HO. It took about 6 months and I was able to get all the parts to throw together a engine.
Install was pretty simple other than a new engine mounting hole in the bulkhead had to be drilled for the HO mounting. The spacers used on the R engine on the pto side, had to be used on both sides of the HO. mag and pto. Doing this brings the pipe up to R engine level and without this, the rear engine torque stop was hitting the reed housing.
For ease of utilizing the Perc, I bought a RR complete wire harness to run on the 2021. Plug and play on the engine.I converted to the old round gauge, had a custom gauge surround made, and trimmed the console for the 10.5 tank
I am marrying the RR harness at this point to a HD regulator/rectifier. This due to the dc lighting (ho has AC). Still not sure if I am going battery, or capacitor to keep lighting from flickering.
perc works perfect, but still have to modify the snowflap
