Here is a trick you can do for more power Advance the spark. I saw two magneto and that might have an adjustment. 1 use a rotary file, cut slots into the mount hole and elongate the mount holes. Use a large washer afterwards to lock it down and keep tensions 2 not sure if the flywheel has a key. If it does, grind the key to half the thickness so you can advance the spark by rotating the flywheel on the crank 3 if you have a small airport nearby, pickup some blue gasoline. When I did it was 108 octane high lead but I think it is 100 octane low lead now. Not quite sure. 4 mill port and polish the heads. Possible a thinner gasket. Take a 4 inch bolt, sandwich some coarse steel wool between two large washers, and get a drill and polish away. Remember to blow the doors off everyone around you. Vroooooom Just some old tricks to get more power

[@ВикторХрамцов-х3т]

[@GuernB2]

I did this on my 99 Miata. I have been running a 5-degree advance for about 10k miles with no issues, it definitely had a small but noticeable bump in power.

Old School tricks for sure!

[@samsnephew3209]

Fyi, that is called timing gain or delay. The carburetor can alter time if he sets a higher idle with slow time it will synchronize at the high rpms. Dragsters have used this over 50 years.

[@thepirate5955]

Whoa - can you imagine this engine in one of those old Citroen 2CV's? Crazy.

[@redman112010]

I used to run a honda twin on a pulling tractor and we loved it. We made a custom intake and manifold ourselves, milled the heads as much as possible, stroked the crank .60, and ran stock rods and cam, it turned 6k to 7k rpm easy and had tons of torque. I've been wanting to build a preditor the same way and now that I know you can get a cam and everything, should be awesome.

[@rncboy2]

The original hole for the govenor shaft I would recommend tapping for a fitting same with both valve covers. The reason for this is to keep the oil in the block and so it doesnt build up in the heads. I know it's more prone for the single cylinder engines like the 212 because at 7000+ rpm you dont wanna spin a rod bearing. It helps the oil flow back into the block and not build up in the head.

[@elivestin5353]

Very nice build! However, I would put the front cover back on as it's responsible for directing the air from the fan on the flywheel up onto the cylinders. Thus cooling them

[@shdwwzrd69]

Only thing I'd recommend and it's on you is a bullet fly wheel because those cast ones are known to self-destruct at high rpm

[@mercedesvan-doors34]

I raced small capacity 4 stroke twins in the 80's and these carbs a re very similar to the Mikuni units we used. Here's something to try, put a connecting pipe between the two inlet stubs and then balance the carbs so they flow exactly the same, when balanced connect the new pipe and test the difference. Also this engine would almost certainly respond well to a reverse cone megaphone exhaust, a little experimentation could give good results. Nice build and none of this is criticism just passing on years of building em.

[@speedskid4838]

The sticking throttle linkage line was a good reference. Glad to see your doing better Vasily!

[@esqueue]

Good video. Very informative and entertaining. I managed to laugh a bit at the joke. Keep in mind that I did damage a car's engine by using heavy weight oil. The engine just didn't get hot enough to flow the thicker oil correctly which resulted in rod knock. One of my many lessons in life to not always pay attention to what you read on forums.

Thanks for the demonstration. Love that sound!! And not obnoxious even with a straight pipe. No big bulky expansion chamber! Planning on putting the engine in my ultralight after putting it on a diet with all the upgrades, including a much lighter flywheel. Two Arrow carbs so I can adjust for altitude while flying. It should sound better, look better, and be more streamlined without the bulky expansion pipe hanging out the side. Then perhaps a AMR supercharger. It looks like rebuilt ones are only $300.

[@terrylutke]

Hi..liked the video, nice job. I use the Predator and similar HP V2 engines on ultralight aircraft. The engines are installed stock but without the governor. In our case propeller load controls engine RPM, usually set at about 4000 RPM max. Engine reliability is especially important in aviation so I'm reluctant to boost the engines all that much. As HP is boosted, heat dissipation becomes a greater concern. I'd install head temp or oil temp gauge to monitor heat, especially if OEM air shrouds are not used. Oil cooling is a great way to control engine temps. The OEM oil cooler rad depends on shroud controlled air flow to provide proper operation. Without the fan and shroud I would consider a larger oil cooler if engine heat becomes an issue. I'm guessing an after market automotive tranny rad would be something to look into.

Just to be clear, thicker oil isn't necessarily better. Too thick and it won't get into tight places and will cause lack of lube.

It doesn't matter if you remove let weight if it's a cast flywheel because it probably have small and bubbles. And billit flywheels have way less bubbles and are more solid than cast ones .

The only problem with 50 weight oil is that it won't flow well when it's cold. Not when it hasn't been Star Ted in a while, when the weather is cold. 50 weight is racing oil, and pretty much everyone that used to use it has switched to light weight synthetic, and this includes nitro cars!
