No unless they sell trike bits you will have to give them the bits.Originally Posted by kilabeez0
If your having the head done, give them piston, seals, valves etc to get correct measurements done.
if your only haveing the barrel honed, just hadn them the barrel and piston

nothing unless your cam is worn any. if it shows signs of wear might as well replace it while you have the motor apart. look for heat marks on the journals and the lobes too. also check the surfaces of the rockers where they meet the cam lobes. they should be smooth.
if a vegiterian bites their lip, do they feel guilty?
yep, thats our man. he pulled himself into an airduct. he must have worked out for months!

Catch me if you can
Now don't get all confused, I tried to be as specific in my post as I could. As far as the cam - there again there is a spec in the book for cam lobe and journal diameters. Just mic them up. Problem with four strokes is alot of people don't maintain them and a lack of oil in that head will cook the cam, rockers, journals etc. Just measue them up and look for scratches or scoring in the aluminum where the cam rides. If there's play in a shaft then it's on it's way out. But I thought you got a good head?? Thats why there are so many ATC parts, noone can keep the motors going usually due to lack of maintenance. Too bad everyone didn't know that the smallest amount of damage to an aluminum journal will destroy a whole top end. These motors really do require time and patience and 1 mistake will make that repair last less time. Have you read the manual about inspecting parts??
My mechanic told me years ago just to pour gas in there and see if the valve leaks it past and if it didn't he left the heads alone.
