IMO Everyone who says that these engines will blow up need to stop and Google NKA AKRA WKA box stock racing classes. We remove the governors all stock internal including rod and valve train. 10.8 pound springs and all. The only aftermarket parts allowed is the flywheel. And that's for safety we turn these things upward of 7000 rpm maybe more. Only part to worry about is the flywheel. The stock one are only good up to like 5800 before they explode. You are fine the valve springs won't let you spin it that high before they start to float.

[@andreafranceschini3889]

Please, stop caring about all the peolpe saying you're wrong, most of them cannot do anything that you're doing. Sometimes I too watch your videos and think you are doing it wrong, but truth to be told there are always more way to do stuff, and many of them are good. Also you are a lot more experienced in building stuff then me and 99,9% of the people who are watching your videos. I mean, if you look to your first videos and your last you see how you improved. Keep doing cool stuff and just enjoy it, read the constructive suggestion, not the "you are wrong" comments 👌

[@Reman1975]

Personally, I'd put security cameras (With audio) up all over the place, get a ride on mower, knock all the baffles out of the exhaust, and trim the grass once a day until Mr Grumpy to lose his rag again. Then when he eventually comes stomping over, report him for REPEATED threatening behaviour and trespassing. I'd also be tempted to do a little community PR work at some point too. Next time there's a large local charity fundraiser type thing going on (Preferably something to do with sick kids), you could sacrifice one of the go karts you've got kicking about by repainting it like new and publicly donating it to be raffled (As seen built on the 400,000 subscriber strong KZbin channel "Rather B Welding"...... Sure that would help with the biding. LOL !). The local community will think you're a such a kind young man, The neighbour will look like a grumpy old bastard if he complains again, and to be honest, you could probably do with freeing up a cart parking space by now. :)

[@mrnautilus]

So a quick rundown on the governor thing, I'm sure you already know all this but for anyone else wondering. *Removing the governor in and of itself will not blow your engine up. That's the short answer.* The long answer is that revving your engine without the governor with stock internals could damage your engine. With the governor, engine RPMs are limited. When you remove the governor, engine RPMs are not limited, and thus the first weakest link in the engine is what limits RPM. In this case, RPM gets limited by the valve springs. The stock valve springs begin to "float" and are not able to handle such high RPMs. They will essentially cap your RPMs to around 5000-5500. Floating your valve springs could allow the piston to hit the valve, bending your valve, potentially damaging your piston, and in the end leading to compression issues. This is not "blowing your engine up" so much as it is damaging it. The way around this is to upgrade to stronger valve springs. Now that you fixed that weak link, you're limited by your next weak link - the stock rod and flywheel. These rods and flywheels are not designed for high RPM, and can shatter if revved too high. *THIS WILL* cause your engine to "blow up". If the rod goes, say goodbye to the engine. Often times when a rod goes it punches a hole in the block itself. If they flywheel goes, well, it depends. If you're a guy and you're on a minibike, kiss your chances of reproducing goodbye! OK, seriously though, when the flywheel goes shrapnel can fly out and cause severe injuries. This is why if you take your governor out, it's better to float the valves than to upgrade the springs. The way around THIS is to upgrade the rod and flywheel with billet replacements. These billet rods and flywheels can handle extremely high revs. Upgrade the valve springs even further (and also consider upgrading the pushrods to chromoly pushrods - not required but the added safety never hurts) and you will have a much more reliable, safer, powerful, and higher revving engine.

[@sanesaint8725]

[@stephenlapek7547]

I've removed plenty of governors, only had 1 engine come apart. It's all about the fly wheel. Big heavy stock one is unbalanced past 3600 rpm and the magnets can fly off. (Can, not Will). This throws the balance off everything and it wont take long to wreak havoc. Billet fly wheel is the way to go to prevent this. Also much lighter. Heavier valve springs are a must at higher rpm. The stock ones will begin to float. ( won't fully close)

[@Ratkill9000]

I wouldn't worry about removing the governor. The only issue that a few have run into is that after 3600rpm the flywheel becomes unbalanced. With it having a lighting coil, the magnets end up flying off, throwing the flywheel out of balance.
