No trouble.
I have a "thing" about opening engines over, and over again... I DON'T LIKE TO!!! The more times you open these cheap engines the more of a chance of stripping a thread somewhere. Try your new rollers first. You may have to go lighter than you think because your control spring is now weaker. Something else that I like, and use is the Malossi torsion controller. Its a simple nylon type "pad" that sits under the clutch itself, and on top of the spring. It sort of pre-loads the spring, and eliminates the metal to metal contact between the spring, and clutch. If they do not have them for the 150cc engines, I plan to make one. It's just a nylon shim about 1/4" thick with a groove that the spring seats in. Simple enough... Post up your results. We all like to read a success story, and the trial, and error that goes along with it. Best to ya!

Generally, for a daily-drive 150 gy6, I use stock contra spring and RED shoe springs mated to a steep-ram 115mm variator w 12g flat slides. Variator mods make a much bigger acceleration gains rhan clutch mods. Clutch mods are pretty pointless unless you're building a drag-scooter
