Friendly Powesports Screwed up my 1985 Yamaha Vmax motor slidell, Louisiana

Took my 1985 Yamaha V-max motorcycle in for carburetor rebuild on all 4 carbs. also back tire new brakes oil change and the 45,000 mile service which would include vavle adjustment or at the very least check valve clearances.  They had the motorcycle for 1 1/2 months telling me everything looks great there was a small leak on one of the carbs. i could have it back soon as it was fixed then i recieved a phone call to the effect the motorcycle was being sent to the Baton Rouge store to fix leak 2nd day there I recieved a phone call the motor needs to be completly rebuilt low compression on 2 cylinders after having been told the motor runs perfectly from the slidell store.  I BLEW UP they told me they would comp. the charges from the slidell store 1320.00 usd and would try a valve adjustment as one would expect it either didnt happen or it didnt work.  As it stands now the motorcycle will be in Baton Rouge store until next week then i will be able to pick it up at the slidell store.  i was in contact with the slidell store the entire time they had the motorcycle and even went by the store 2x they constantly reassured me the bike was running great to find out something has been done by what appears to be unqualified machanics i already have another machanic waiting for the delivery of the bike.  He is going to walk through it and if there is evidence of them messing this motorcycle up under standard service i have every intention of getting my lawyer involved
