@@Noah-u2z huh, what’s that supposed to mean?

you have the same problem with the ULKA pump. Problem is not with the pump, the problem is with hard water calcium buildup in the pump. that will happen to any pump you throw in there.

*Ulka 53w shows as a 220V pump, not 110V, will it still work? Thanks in advance*

This chain tensioner works great. Never have an issue with it throwing a chain. Keeps constant pressure on the chain so it doesn't slap around loose.

@justinsauer5682 Awesome. I'm running a Duromax 440 (basically the same as your Predator 420). I have the same engine plate too. I have plenty of room to move the engine to tighten the chain but I got tired of constantly adjusting the chain before and after every ride. Last thing I needed was to get stranded. Thanks again for the idea.

You need to install heavier springs when the governor is removed the higher rpm and stock springs will cause your valves to "float" you can Google it and read more about it. This can cause the piston to hit the valves. I never ran into any issue after installing 50lb springs. Good luck.

Also be aware on the newer 420cc predator, the stock iginiton coil has a built in spark limiter that limits the RPMs even if you remove the governor. You need to install after market coil or the old style coil without the spark limiter.

Honestly it's the best machine I've ever purchased. I had the same issue twice. Purchased in 2018. First time, I called customer service and a technician told me, remove the screws on the curved black plastic vent piece near the wheels just pull it down then take a wrench and knock, bump, hit, tap the pump (hardish) works 99% of the time, once its spraying agian replace the panel and tighten screws. I try not to leave it sitting in the soapy solution to long. 😅

The swingarm was part of the go-kart. It's been modified to accept the 420cc engine and mounting plate. I have a video on the modifications to the swingarm on my channel. Engine Motor Mount Plate Compatible with P-redator Engines 420cc 670cc a.co/d/0Rh3NPt

Thanks, I've got a lot of content to upload. I installed billet flywheel, alternator, front brakes. Stock 420 ran fine for me. You say the kart barely moves as long as the throttle linkage moves the lever you should be fine. What are the symptoms? I ran stock for a while before modifications. This video was stock 420cc kzfaq.info/get/bejne/pL6GpaqVz6jOhWQ.htmlfeature=shared

Thanks for the quick replies always, I just feel that the gas pedal doesn't move the lever enough to really get it going. It could just be the gov. Still messing with it. Ive built a 212 with billet stuff and connected throttle cable straight to carb butterfly valve, I was just hoping to keep the 420 stock and not mess with it.@@justinsauer5682

@@user-cc7be8bu2j if your throttle cable is moving the engine throttle lever its full range, as if you were moving the throttle lever by hand, then the issue is not the throttle cable. Just make sure the engine throttle lever is being fully engaged when you press on the pedal. Another thing you can do is look in the intake of the carburetor, the butterfly should be completely opened at full throttle (pedal fully down) if not then your throttle linkage is screwed up somewhere. If you're air filter is extremely dirty and restricting air flow that will also cause it to run sluggish as well l. Governor only engages at higher RPMs to slow down the engine. I don't think it's an issue with the governor. It should run well with it in, with lumitted RPMs.

Thank you, I adjusted the throttle to already pulling on the arm more and its better. Im positive I will eventually go billet on rod and flywheel again... lol. what's your opinion on the shift to bypassing the gov and connecting straight to carb butterfly? Much better?@@justinsauer5682

@@user-cc7be8bu2j you'll definitely tell the improvements removing the governor. I'm not sure how just to by-pass it. If you remove it, one thing you need to know the ignition coils of the 420cc still have a spark limiter in them so you'll not be able to reach max RPMs unless you buy the an ignition coil without the spark limiter. That's what I did. Careful though it's recommended to upgrade to billet flywheel if you're planning in running max RPMs. Cast iron flywheel could explode at higher rmp 4k +.

Thanks, measured at the back of the swingarm inside of the long square metal tubing to inside of left swingarm 6 7/8 inch.

Yes I used 2 stock master cylinders in tandum. One brake line to the front to a T then off to each front caliper. Yes, I need to put together a video of detailing the work. Maybe this weekend.

@@justinsauer5682 thanks in advance if you do🙏🏿

Check out my channel. I've since installed billet flywheel, alternator, no current ride videos kzfaq.info/get/bejne/fduSja18ubjFk58.htmlfeature=shared
