Performance parts for gs850g.

[Moarpower]

Just curious about what performance engine parts are available for the 850g.

I bought a bike with a claimed 11-1 high compression rebuild done but I'm unable to find evidence to support that claim nor can I find many parts online for the 85og.
The are lots for the 750 and 1000/1100 but the 850g seems like the forgotten stepchild when it comes to upgrade parts.

I need to pull the head and replace gaskets etc and would like to add new pistons and rings, valves and spring upgrades.

Search for an 1100G engine to throw in your 850's frame. That's about the only way to get more out of it, I think.

Edit: Depending on what year 850 you have that may not work.
