Just got the Amstar Rocky. Really excited! This thread has been super helpful in the last few days since I got it. Mechanical tips, morale support, I laughed, I cried, I also removed the transmission drain cap accidently and the spring and rod popped out, it's been great. Thanks.
I ordered the CDI that was recommended hoping it will juice my ride as you all have described. It seems like the biggest issue I have at the moment is, having the bike crap out on me somewhat randomly when I accelerate from stopping in first gear. Most times I am alright, other times, I just putter forward and sometimes stall out completely. Almost like I am running low on fuel but am totally full. Anyone else have this experience?
Also its clear to me the intake is being strangled at the stock air filter. Anytime I give too much throttle I can hear the popping, like gasping for air. I am not looking to change out the whole carburetor just yet but didnt know if people have had any luck just swapping out the filter it came with for a higher performing type? Or should I just rip the bandaid and swap out the whole carburetor?
I figure start slow and leave the restrictions on the Rocky for the moment as I break in the engine properly. But once I get this guy dialed in I definitely am going to want more power, I am barely scraping 47 kph or 30mph Ish on straight aways.
Thanks for any replies!
