Hey everyone. So i blew my jug for the second time, cant believe the bottom end is still in tact over 2/3-ish years. I ordered a top end rebuild kit from motorizedbicycle.ca specified as the GT5A kit, note i have a GT5. upon inspection and comparison of the recieved kit vs what i bought 2 ish years ago, and I may be a baffling idiot, but I think i have been sent an updated model. The differences I noted were the exhaust shape is actually a circle now, which is what a proper 2 stroke should have, note it also looks a lot larger. The intake seemed to be made from a more durable material, and the intake manifold is actually port matched! the transfer ports seem to be at different heights, and as you can see the exhaust port is a lot closer to the transfers. I did also notice on the cylinder head there was an additional bar welded on that was not present on my old head, guessing its for durability. Really excited to rebuild this!!! Hope this is not actually just normal and i sound like an moron posting this
