Hey guys. I've been running a GXII-5R that I picked up from Amain when they were clearing them out. I've been having problems with tuning. I'm running the 2072 pipe with VP 30%. The past few weeks it's been running good but would bog on the bottom. If I tried richening the bottom I would get flame outs between 4-5 minutes into a tank. I had the LSN about 1 1/2 turns in from flush and the HSN was 2-3 hours in from flush. This weekend after a couple of flame outs a friend with 20+ years experience helped me with the tune. He also runs GO engines. He ended up raising the idle, fattening the LSN, and leaning the HSN. It ran good but felt like it wasn't making as much power. I've gone back and read through here and it seems like some people say 1-1 1/2 turns in on LSN and a couple hours in on HSN to the exact opposite. I'm getting really frustrated with this motor and need some advice. Thanks
