Got a spare carb for predator 79cc and I would like to try boring it out a little. got it all apart but I cant figure out how to get center tube out. Its the one right above main jet and it has no screwdriver slots in it so question is how does it come out?

I'm going to use a pe 19 to match the AGK intake but a 17 is going to work on a stock 79... Nibbi store on eBay has you covered if it doesn't work out with the stock carb...

Thanks for that info. I just had a spare carb and it was only like 12 bucks so I thought I would see what I could do with it. So far I have removed governor added better exhaust jetted carb and free flowing air cleaner and got the schwinn meridian up to a whopping 20 mph with the 79cc.
Before all that it was top speed of 17 mph going down a slight grade. That is one sweet looking carb to might just give that a go.

I've been messaging the engine builder and I think I found a double ball bearing for the 79/99cc and possibly some seals I won't know for sure but it's worth a try... Basically the only 79cc HF parts are the block, rod, head casting and fan shroud...
I've put a lot of study into the 79...

Pretty sure you can order all the parts right from harbor freight. Just go to the motor on harbor website and it will have a parts list for repair. Again pretty sure not positive

This is where I've been shopping for 79cc junk... The coil he sells is something... There beginning to use plastic cams... The steel ones are becoming obsolete... This is the only seller I could find that has everything...

Thanks for info on parts and I have seen that plastic cam. It was part of the reason I took out the governor plus my motor is not a true predator it is a gasbike trike kit but all predator parts I have used fit it.
I wonder if I could get parts for it from gasbike?
 
That's good to know the gas bike 79cc kit is predator...
I got thinking about gear ratio... If my final drive is 6:1 and the 30 series goes from 3:1 to 1:1 is that a total of 9:1 to 6:1 or 18:1 to 6:1... I'm trying to figure out if it magnify the final drive or add
