Hi guys, just want to share my experience with my GO .28 mill, last weekend I raced my truggy at the Singapore 1/8 Offroad Championship. I did managed to qualify at the A-main. When I got back home and checked my engine I saw a nasty scratch the whole lenght of the piston at the side where one of the opening for the wrist pin is seen, upon closer look the G clip was gone, this could have probably caused the damage in my piston and sleeve .
Since the following morning the finals will be held, and no spare engine at hand, I have no choice but to use the damaged engine without one of the G clip holding the wrist pin. The a main is an hour race, and luckly I did still finished 6th without any problem with the engine, the only problem is that I broke my steering linkage which I still manage to fix.

Now i'm planning to get a new GO engine a .21 instead of a .28. Guys which is better for truggy the GOLD or the SILVER?
