Hello NC brethren . Sounds like you may have a trike that was ridden through some deep water that was put away hard and wet . Changing the fluids is a good start for sure . Pulling to the right could be a combination of things . Take a close look at the triples and see if they are aligned , then check your hub - rim area . You may want to check the front brake to see if it's sticking ; not so much for the pulling but to see if it was run through deep water and might be worn or rusty . Search the threads on here because there is a ton of good info .
