Nice build. With a motor that big, i'd gear very carefully with that series 30 clutch. Shoot for 30 mph max speed, at 3500 or so rpm. Use revs to go faster. This will be alot slower than your current gearing, but it will be very torqey and fun. You can remove one of the primary clutch springs entirely, and they used to make lighter springs. They also used to make a heavier yellow spring for the secondary, that would help alot with the increased torque from these big motors. Ive had a setup like this going 65 mph, but it shredded belts and destroyed primary clutches until i geared it lower. Hopefully that all makes sense, for your consideration.
Very nice of you to lend a hand. However, this is not my first go round with one of these motors. This thing has been built up with a performance cam it has been port and polished and shaved. It has the black, venom roller rockers and titanium pushrods a performance carburetor, this thing idles at roughly around 2000 to 2500 RPMs or at least I think it does🤔 anyhow, as far as the clutch I stretch the springs the bottom, one more than the top so it engages quicker and I shaved down the torque converter belt on the flat side so it does not throw you forward when you ease off the throttle Therefore, it has much better coasting. top speed with one of these motors is 63 miles an hour before building it up!
That's what went to crap for me, the conservative gearing helped keep them together tho. Ultimately just went to series 40 then I could hold the torque alot better, and go faster without parts blowing up. That was one of those fancy red predator 459cc engines. Even 40 series hard to hold the torque.

@@TheManCaveMetalFab2580 stock series 30? Other than mentioned mods?
@@CK-mf6du 30 series torque converter. Yes, but I wouldn’t call it stock. Cheap yes, lol
@@TheManCaveMetalFab2580 pins and weights stock in primary?

I like it, sounds good! Try a sprocket idler in the same size chain, its better.
I have one of those, but they seem to be very temperamental when it comes to adjusting i the motor side to side
This is amazing,
Are you based in Australia?
No, I am in New Mexico USA
Where did you get that air filter from man
I got it on Amazon. I think it’s called a pancake air filter. And if I remember correctly, it is not a prime item.
