New owner of 86 RG500 Gamma, needs, questions

#1 Post by Yellow02Z06 » Fri Sep 08, 2023 12:54 pm

Hello all - I recently bought this - seems to be a fairly active forum - hope so - Facebook reducing forum activity is a real drag....

Anyway i have a few other water cooled 2 strokes and love em, do as much of my own work as possible....

Looking for:
1) Already cut rear fender
2) Tail section plastic OE of aftermkt (but plastic aftermkt) - needing paint OK
3) same as 2) for 3 pc lower fairings
4) JL or other side by side expansion chambers
5) Lance or Dent air filters

Questions:
1) I see in many places that the advertised 95 hp at crank is not true - can someone verify this - my stock, fairly good running bike feels like 80-85 at crank, 70-75 at rear wheel
2) Assuming above is true, since I have an RZ350 with Toomeys etc making about 65 at crank, I want an RG making 95 or a little more at crank...
a) Can I get there with just filters and jets or;
b) good expansion chambers and jets or;
c) do I need expansions chambers filters and jets or more?

Thanks in advance!

I'm in California. Their is a slight improvement in the mid range. I went up one or two in the main jets. Whats with the cut rear fender? I install 1994 GSXR750 forks with that done and a 1994 GSXR750 swingarm. I had to graft half of a VJ22 and RG500 bird cage to clear the forks. I used VJ22 front cowl and VJ22 side panels. The rear panels are from Rick Lance one fiberglass piece.

I just want a cut rear fender so I don’t have to cut mine….I hate the look of rear fender going straight down form otherwise nice shaped tails….
