Extreme Predator 670 Carb Tuning - MUST WATCH

What's up KZbin!
This video covers what we had to concur to get our Harbor Freight 670 V-twin running just right. Its no secret this issue has been a consistent battle with this motor since we got it almost 2 years ago. So I ripped the carburetor off for the last time (HOPEFULLY). I made a list of the products I used to match the OEM predator jets. just note you cannot go back from doing this adjustment!!
Enjoy & The Official "Golf Cart Clutch Review" will be posted soon, parts are on order.

you can drill a hole one both the barrels and add a small vacuum ports. also add o2 sensors for the exhaust and add a wideband gauge. that's what i did for my honda gx630 takes all the guessing game out! and a timing light that offers rpm feature.

I’m actually gonna be throwing some up at the cart this year or the different clutch, alternator kit, and more than likely go with a Mikuni carb. But definitely a good idea.

Keith if you still got those gears out of your ME29 gear box that you did the speed gear swap out I would like to buy them if you still have them.

[@keithellett4283]

I sold those years ago, I always buy my stuff from CPP. they are great. just make sure you order the right stuff.

Where are you located ?? I was thinking about matching the jets the same size. I’m in iowa and we’re about 1000 ft

[@keithellett4283]

South FL, I would match them reguardless and i'm sure it would run better just from doing that. For the Elevation difference I would just play around with the mixing screws. Turn them both in all the way and 1.5 turns out each and use this as a baseline. Good Luck

How’s that comet clutch? I need to swap a clutch on my vanguard 18hp and don’t know which to go with

[@keithellett4283]

For what I paid years ago it was a no brainer. i think it was like $130 then, I lost a few MPH but overall no complains. I went back to my CV -tech though, lower rpms at cruising speeds for me is more ideal

Where did you get your torque converter and was it expensive?

[@keithellett4283]

amazon, they where cheap when i got it, not so much now. if your on a budget its cheaper than Vegas Carts
