I am running a blowout special on the TQ501T engine. I have 2 left and I am letting them go at cost to make room for more engines. I have an engine and I have an engine/pipe combo. They both will come with the updated carb throat to keep the engine from vapor locking. Someone at the factory thought a steel throated carb body was a good idea so they have all been replaced with the composite throat. They are both in the sealed box and I will also do a dealer cost special on the race porting if you would like to do that as well. PM me if you are interested in one of these engines!! Thanks everyone for your continued support!!
