Extremely clear and descriptive. I'd let you teach me anything. Very pleasant experience watching, and I don't even own the bike yet.

What if you have highway bars?

The motor Hawk Tao Tao 240cc mount to the twin tubular cradle but the ground connection - it must be scratch the black paint off and then install the mounting bolts and hex nuts. For better starting.

The kick jack does one thing it is a stand for stay lift up the rear wheel of the Hawk 240cc. Shift to 1st gear and fire and crank it with much more powerful motor electric starter that it runs the gasoline motor running I. 500 RPM engine speed. Then pull up the kick stand and some.pop wheelie then wheel would Revolution at least 1600 RPM for it to be flywheel heavy called. Counter weight in harmonic balance it out. Please, call for more order many parts called Rocker arm stainless steel riser gasket from MotoCult for under $25.00 a piece I to the stock as coming from mail order for USA Hawk 240cc motorcycles.

Brigg and Stratton all steel cylinder wall Vanguard into modifying instead of bottom key way shaft with lawn blade. The flywheel is heavy hub as long as crank up the most powerful motor starter the wheel with a little loose chain roller being a flywheel plus up front balancer flywheel of motorcycle technology.

Magneto and e-coil is great just like Bring ANF Stratton with our 5 speed Hawk bikes.

Magneto Retardo Electrical delayer, it forces the RPM into lower as 600 rpm idle timing chips.

The flywheel is basically needs to run the distributor like Harley Davidson single bore cylinder CG block. It is easier like go use magneto into the parts of flywheel and magneto with regards system rectifier to delay the very advance dwell in the capacitor discharge ignition computer box from similar to super chief single CD250 Zongshen Honda Red Hawk.

The power piston is 70mm big bore kit to exactly equals 250cc Hawk single CG cylinder. The original size is 67mm 239cc TaoTao Pro Cruiser. They sell domed piston for HaoSen racer motor dirt bike 72.5mm piston and cylinder kit only for overbored out the crankcase big hole for it is where the cylinder fits atop the big hole.

Please, sent the part number from Amazon or Partzilla, Dennis Kirk or EBAY for only Hotcams Company for either stage 2 and/or Stage 3 racing camshaft for TaoTao Hawk 240 HaoSen RPS carb. Enduro. Where to get it for under $250.00 dollars?

Great video but whoever TF was cutting down the rainforest in the background should have called off... Ruined the whole thing. 🤦

With just V2 exhaust and nibbo carb...would the performance cam install be of any benefit without the bigger cylinder kit and or the upper end polished kit? Or will the cam only show benefit with big bore kit installed?

Why would you need to bleed an oil cooler? The oil flowing through it should purge itself of air.

Hello! What is the boot to dump the fuel?

now please make a top speed video

Everyone with a 450 is complaining about a stumble at 4000 rpm. Any chance you might work on a piggyback like a Power Commander?

why replace that rocker bolt?

I just got my parts that I ordered 3 days ago from moto cult They came packaged very nice. They gave me some stickers a keychain and a kickstand pad that the 3d printed. I couldn't be happier with the quality of the parts and they have answered so many of my questions. I'm installing the parts tomorrow and I'll let you guys know. Also the head gasket they sent is 2/3rds thinner than stock and stainless!! These engines are prone to blowing head gaskets. So this is a must have up grade. And for 8 dollars, you can not go wrong.

Are you guys going to do the same for the 450?

I am going to get a Halcyon 250 AND the stage 4 upgrade for sure! More powa!

Good information. Will look into the stage 3 kit.

Great information. Now subscribed. Just got a Halcyon 250. Will be ordering parts soon.

My Stage 3 kit only came with 2 shortened dowels, but my bike has three just like the video. Also I didn't have the offset key for flywheel, but not sure if this comes with the kit or not. If not, is there a link for it.

Does this fit a carbed hawk 250 engine? Or is this only for the fuel injected dlx?

Absolutely fabulous step by step instructions that allowed me, a complete novice and mechanically dense person to follow and successfully install a sweet upgrade to my halcyon 250 #696. Thank you Devin.

What’s the break in process for this build , thanks for the info and the super quick shipping !

What are the specifications of each stage? what is your interpretation of a stage? to one person, stage 1 may be a muffler, To another it may be everything external being replaced. a third person will have stripped the engine bare and replaced every single part as they will only pull the engine apart once, and the engine will produce 5 times it's original output. and to them that is the ONE and only stage they will consider... aka stage 1! Quit saying stage, and start saying "intended purpose kit" and say what the specs are. People need to know if a camshaft will get them down a dragstrip or up a steep hill. it can't do both!

What's the hp out put after rebuild ?

Has anyone conducted tests to compare the cooling ability of this particular system with the ones that traditionally emerge from the bottom of the engine? Furthermore, what would be the potential outcome if both systems were installed simultaneously?

Wow! Why would anyone buy the 450 when you can buy a 250 and supercharge it with your Stage 4 kit?

Good video, except for the butthole grinding in the background. I guess he couldn't wait for you to finish an instructional video.

I did everything but bleed that exit line. Will it jist fill on its own after a ride or should i take back apart.

I have been using 65ml oil cooler on my CG250 for almost a year and I can say that these air cooled engines need it, mine is fan assited with a 4" fan relay and manuel switch, without the oil cooler the oil would exceed 265°F when climbing hills and long rides and traffic lights in the city, now 180°~190°F all day riding, uphills, and days where outdoor temp is over 90°F. Without the oil cooler oil changes where 1300ml now with the oil cooler 1500ml. When changing the oil I empty the oil cooler removing the 2 hoses every 1000km or 600mi. The crush washers need changing also.

Great company

What compression should this check at when done in PSI?

THANKS for the video! My Hawk (Spetsnaz 250 its called) was definitely "tight" on start-up but I baby it back to life just as when first arrived apx 1k miles ago. Great stuff you have put together in a kit fashion!

Thanks for this great vid Devin however why wouldn't you include footage of a ride so we can witness the performance and hear the exhaust?

Anyone thats looking for head bolt tourque spec...its 25 FTPounds, rockers are 20 FtPounds. The others aren't critical, don't go crazy. I've snaped a case bolt using a power ratchet on a CG, final tighten by hand.

Probably not as effective, but simpler, *if* it can fit: add *substantial* finning to the valve cover.

@ 5:00. Flywheel removal. Informative BUT rotating assembly WILL turn when removing flywheel! (Any goof can put a ratchet/socket on a bolt and turn it!) Some information was intentionally omitted.

ah- HAH! DAH! mein cylinder...morrr POWWA!!!

Is the flywheel wet or dry

Interesting design but I see a few issues - Would this not make adjusting the valves more of a pain when it comes time? Your website seems to have no specs listed at all? Dimensions, capacity, nothing. At twice the price of a normal CG250 oil cooler I would expect some sorta information to make sure it's not just a waste of money. How much does it actually cool the oil temp? Who knows if it's any better or worse than a normal one with no specs about it?

Wow,bro made that look super easy.Thanks for the video. What did we do before youtube..lol

where do i get that kit plz thnx

alot of mechanical people know this as knowledge, but i didnt hear you say put it on top dead center before hand? or did i not hear it

@Motocult Do the shortened dowel pins come with the 70mm bore kit? I want to order one but I don't have a lathe to knock off the .08 on the stock pins. I have already ordered the stage one kit a couple of weeks ago. *FYI* I ordered a 72.5 (piston diameter) bbk from China, just to let others know, it WILL NOT fit unless the engine case is bored out. I was trying to get a little more CC's but I do not want to go through the trouble of tearing the engine down completely and having it bored, so now I'm stuck with a kit I will not use. The point I am making is, without boring the engine case out, the biggest drop-in install is the 70mm bbk for the Hawk 250... ***UPDATE 1/28/23***: Ordered the ported head, 70mm cylinder bbk, oil cooler from @Motocult. Devin has been extremely helpful. Products came in quick. Installed the parts according to the videos and the bike cranked right up. Had to adjust the idle, which was easy with the Nibbi PE30 carb. Bike feels stout at the bottom end, I haven't hammered down on it yet because gotta break it in a little bit. I ordered the bike Jan 7 and when it came in I didn't even start it until I put the mods on. Mods so far: I have installed the Motocult ported head, Motocult 70mm bbk, Motocult oil cooler, Motocult power cam, Nibbi PE30 carb with 115/35 jetting, Nibbi air filter, Nibbi performance ignition coil with MSD 3311 spark plug boot, Wetenex 6 pin CDI box, NGK (DPR-8EIX-9) Iridium Spark Plug, LED bulbs with new flasher relay, JFG Exhaust, 17 tooth front sprocket with 45 rear, RPS digital speedometer (which for some reason is not working?) and thats all so far I think. I am going to change out the Chinese Olive Oil they used for brake fluid that comes in the bike, and probably the fork oil. Although I would like to eventually change out the front forks as they look pretty toothpickish - seem ok on the road but idk how they would hold up off-road...I will update again once I break in the bike.

How about the cam? Did you have to use a press to get the old cam off the cam gear? Did you purchase a whole new cam gear with an upgraded cam on it? If so do you have a link? Thanks in advance

Is the button head bolt necessary for clearance? I ordered a kit off aliexpress similar to this one and it doesn't include that bolt, but getting one at the hardware store shouldn't be an issue. (edit: just check the valve cover fit without the gasket installed, details in the replies)

I want to buy the stage 1 but do I need my old carb I have a nibbi carb
