1989 suzuki lt500 when i get on it coolant spurts out overflow. When i remove cap it will do "bursts" or spit out coolant. If i feel lower hose its pressurized. At idle no problem. After hard 20 minute ride radiator be damn near empty. Been in shop for top end rebuild twice already this year no more than 4 hours tops since last rebuild. Hesitant to take back to shop. Wife gonna kill me if dump more money into it. Have rode it probally 12 hours total then been at shop sleeved new piston. Spark plug looks perfect. I coulda swore i saw a blank little swirl after took cap off in antifreeze but not positive. No leaks rides awesome. What should i do before wife divorces me?

 

Blown head gasket IMO.
Shop?? Surely you can handle this.
