That's a real performance build right there! You're pulling like crazy all the way to 12k rpm. I doubt I'd ever get the courage to hit those speeds on mine.
Love it. Let me ask u, how do u like those getto bike wheels? I'm trying to decide between the o es u have or the 19" moto wheel set they have. Would love your input.
The ghetto wheels are great, but many people are very disappointed in their service. Might take a year to get, no joke. I like the 26" tires but it seems like a lot of guys are going for 17s and 18s now, even 24s. I would look up Gemini hubs and wheels. They sell them at MBRebel and you can get them in weeks instead of months. All Will Kid is the maker on facebook and he sells hubs and wheels made.
What overlay program did you use? Stupid GoPro only lets me do it on the phone app and then the vid gets super grainy. Don’t want to spend $99 for that 3rd party ‘GoPro telemetry extractor’
Everything you see I have done for free. I use a program on my phone called TrackAddict which records all the data. Then I take that data and put it on my pc with a app called RaceRender. Everything free. If you want to make long videos I think there is a charge but I think 3min videos are free.
Ah that’s perfect, thanks for all the info! My GoPro gps readings are sometimes way off but my phone has always been reliable so big advantage to doing that
Wow so 30 degrees blowdown? If you go WOT continuous from a low rpm is there any ‘lag zone’ in rpm where it struggles a bit with the porting/pipe being out of phase etc? My bikes all have it and some are down to 15* BD. I think my pipe design may be to blame
That nuts bro what’s your set up we would all like to know lol. I’m building two fat bike tomorrow morning nothing like that maybe 45 ish lol.sweet ride.

God damn son! This makes my bike seem so slow 😂 what's the secret to getting some more power. I've got a pk80 and I don't feel like it could even pull taller gearing than the 44 that's on it.
This is a fully build CNC case Athena 80cc, so ya its gonna be faster than a china doll. But chinas can be fast, just gotta put the work in. Ill be doing a full walk around video of the bike soon keep an eye out for it, it will have all the details.
Paul D.B , use a timing degree wheel and grind some proper port timing as well as proper port shape then you've got to get the carburetor jetted and tune correctly oh yes oh yes and let's not forget a proper exhaust pipe. A CNC case don't make more power it just makes them look cool and cool points don't make HP just being honest here. Any Chinese motor of equal displacement if ported properly and jetted properly capable of doing this and more. But yes it runs good, She rips Aey!
A proper expansion chamber will add at least 1hp on it's own. Aside from that, you can port the cylinder (allows higher max RPM), and add a reed valve with a windowed piston. Adding a boost port or a 3rd transfer port in addition to the reed valve will give you even more power

Sweet sounds awesome
im afraid of 2 strokes reving high but in fact 4 strokes at high rpm are more dangerous the piston can catch valves and you end up crashing bad
Transmission
Valves will launch off the cam and hang open as the piston comes back and bends it. Stiffer springs solve that.
The piston coming in contact with the valves has virtually nothing to do with you "crashing bad" 😂😂😂
