The NASKART is a ROLLER! The First DRIVE is Right Around the Corner!

Hey Guys, Migs Here! In today’s video, I am working on the half scale NASCAR, with its new engine out of a 1980 Honda CB750C, and finishing the jack shaft system in order to get the power down to the wheels, reinstalling the axle, carburetors, wheels, throttle control and more to get this ready for its first drive!

you will want to make a heat shield behind you Miggs buddy, those exhaust headers throw out a good amount of heat ;). One major problem Miggs , no front engine mount soon as you run that the engine will flip backwards as there are no front engine mounts to stop it wanting to rotate. use the stock headers for now just cut them down and have them out the bottom of teh chassis, that way you can get a feel for the best placement. and as above you NEED a heat shield those headers are going to be super hot and cook you alive .

[@jedbodinebaseball130]

Very well said

[@OGKILLa9365]

He can wrap the headers in header wrap and they will work good also

[@nikola8843]

Put the clutch on the shift knob and when u are shifting just pressure the clutch with your hand

[@MrTamiyacowboy]

yes shifter stick then add a clutch leaver to the shifter leaver one hand does both the shifting and the clutch, you do not have enough room to add a clutch into the foot well without it impeading either the brake or throttle , IE your foot will catch either one when you try to dip the clutch peddle

[@newscooler12316]

the sprocket on the engine and jack shaft look like they are at different angles/ crooked. also should have welded the sprockets to some collars or hubs so you can remove them.

[@muddingcanada6550]

he right ^

[@frasertive2726]

He doesn't drive the stuff enough to need to replace the sprockets so they will last a long time

[@newscooler12316]

@@frasertive2726 yes but what if he needs to change the ratios!?

[@theozman38]

Why am I having a problem with his jack shaft mounting ?? I think the first time he gives it a lot of throttle it’s going to bend and hit the motor. That mounting he has welded on is just not looking strong enough. Just saying. You need to build a platform for the jack shaft to mount too. Get some more 1 inch square bar and a good thick plate of steel and weld a good platform for the jack shaft to mount to. Don’t be afraid to use nuts and bolts on this. I beg you to use some if not more. Your jack shaft mount is shitty mr. migs. Maybe you got an important hot date somewhere but fulfill this first. Like I said before in a previous video. I don’t want you to fail and last but not least I don’t want you to be hurt. Think about it sir. Be safe.

[@officialkidathegreat4302]

[@ah617006]

Yes, I had this concern in the last video

[@supertedogpriken]

you should NOT have welded on the sprockets with the stock Motorcycle gearing. The gokart wheels are half ish the size of the motorcycle wheels så the gearing is way off. And please mount a Dirt bike/water jet deadman switch to that death trap. You need a way to kill the engine if(when) everything goes to hell. There is a BIG chance of the carb pistons getting stuck in wide open throttle because of the scratches you made on them the first time you pulled them out. I know you sanded/fixed it "migs style" but smale micro scratches can make the piston stick. so please mount a dead man switch to the engine.

He won't ever need to as he has all these bike and doesn't use them

[@braydendenlinger9428]

Or if gearing needs changed.

[@frasertive2726]

You could get them off lol it would be a pain but you could

[@supertedogpriken]

he is using the stock gearing for a 18-19" motorcycle wheel, and the ass cart has 10-11" ish wheels. so we already know the gearing is gone be WAY off...

[@lennym1273]

If he needs to change them he just has to get a new jack shaft he bought a long piece, just re-do it all and this time do it right...

[@lyonagius]

The tensioner should be under, because when you roll the nascart the top side of the chain will tighten it's self and the bottom of the chain will be to loose. Hope it helps. Great vids.

[@lennym1273]

Nope I thought that same thing till i took a good look on the small chain yes on the bottom but on the large chain it is backwards it needs it on the top , because if the engine was in front of the sprocket it would be on the bottom...

[@davidflaibani877]

I love your videos keep up the great work

[@brockviau7832]

It's so easy to make a jack shaft correctly you make some mounts for the pillow block bearings so the can slide back and forth with bolts and be easily removed then you buy a shaft that has a keyway or have someone put one in it then you buy sprockets with set screws and keyway then you get axle collars and lock down the sprockets, you basically did everything wrong, it takes less time to do it wrong but more to fix it and do it the right way.

[@jok3yjesu339]

From the engine drive to that spocket I honestly would just slot the holes on the pillow blocks and slide them back to tighten that since you have that spring loaded tensioner you can get away with having the chain loose while the other side is tight

[@anthonycantando7255]

As soon as you give it gas the jack shaft mount is going bend towards the motor

[@alphagamer6651]

Another high quality video from Moto mig's

[@taurienhill5355]

Nice work it coming together have you thought of mounting a clutch lever on the steering wheel for the clutch

[@OGKILLa9365]

You can also put a dirt bike clutch lever on the shift lever that you're gonna use..

[@MrTamiyacowboy]

Another quick one MIggs , DO NOT throw away the old airbox , those carbs work on a vacuum and they will require the old airbox to run sweet, if you dont use the original airbox and go with pod filters you will find after 3/4 throttle the power breaks up and it becomes spluttery. You will also need to re-sync those carbs and make sure all the throttle butterflys / choke butterflys open and close at the same time ;)

[@charleswebb7155]

You should build a removable scatter shield for the top side of the chains. I’ve had a few fly apart and it doesn’t feel the greatest.

[@outdoorman6018]

Just add the clutch lever to the shifter it will save time and it will be long enough to work

[@arthursmith5409]

Cool meter is rising, hitting bout 85%. Doing great kid.

[@1981dasimpson]

a good place for that kind of cable is a bicycle shop as they can make them to any length you want

[@cosmicsealgaming]

Issues to consider before driving. Lube the chain. Reinforce the jack shaft. Heat shield. And get some air dams to force air to the air cooled engine.

[@Wildrose_Ronja]

You can drill a few holes in a woorden board, one just as big as the gas cable, drill iT horizontal,the other one just as big as your old connector, drill iT vertical just at the end of the horizontal hole.Than you can solder your OWN connection on that cable.

[@braydenschroder2695]

You should make the next video like 30 minutes or 40 and get it all done in 1 video great job👍

[@lyndonwebber1389]

Who remembers mr blobby well he’s back in the form of this guys welds

[@trail-tr2ql]

Looks good, but you need to brace up that jack shaft and put some rubber between the motor and mounting thing you made, it else the motor will rattle a hole in itself

[@milesrichardson1399]

The sprocket on the axel is moving up and down take the sprocket holder off and line it up properly when the chain spins itll tension up and loosen when its spinning

[@jamescuartero]

Hey when you do get the engine running make sure to synchronize the carburetor put a synchronizer gauges on there to see where the vacuum reading is

[@christianlucatino1910]

I would definitely reinforce that jackshaft a lot before putting it under any sort of load. As far as the exhaust headers go if I were you I would chop off the exhaust flanges off the stock headers from the motorcycle and weld custom headers for the naskart. I would also mount a dead man switch to the front in case the whole thing goes to hell

[@lowlowsandclothes9923]

On the throttle cable you can melt the tip and make a new one of sauder look it up good luck

[@seanbennett1459]

Please read this to this how how you sync the carburetor you will need to do this with the carb since you cleaned the carburetor an rebuilt the top end basiclly... So if you want that 750 to run good do this.. CB750, XS650, KZ650 CARB SYNC & TUNING Advertisements In order to get your old Japanese motorcycle project running well, you’re going to need to spend a little bit of time thoroughly cleaning and syncing the carburetors. With a little patience and the right tools, cleaning and syncing carbs is not a terribly difficult procedure. However, depending on your motorcycle’s exact set up (i.e. anything other than completely stock - cylinder bore, pistons, exhaust, and airbox vs. pods) you may find that you need to try different jet combinations to get your machine tuned and running properly at all throttle positions. Materials you’ll need to sync your carbs: Vacuum gauges (with plug hole extenders depending on your motorcycle) Auxiliary fuel tank or long fuel hose. Proper sized wrenches for adjusting locknuts. While you’re at it, check out info for timing the ignition on these bikes. CB750 Honda CB750 Carb Sync Instructions: Initial CB750 Carb Sync: Remove the fuel tank and set up an auxiliary tank or a long fuel line to the carbs. Remove the air cleaner to confirm proper operation of the choke butterfly valves. If the clearance between the choke valve and carb body is greater than .5mm, adjust the choke clearance by lengthening or shortening the choke lever adjustment rod. Adjust the throttle stop screw to line up the T mark with the indicator on the carb body for each carb. Loosen and adjust the throttle cable lock nut and cable adjuster so that there is about 1 to 2 mm of play in the cable. Make sure the play in each carbs cable is the same. Turn each carb air screw until it seats, then back it out 1 full turn. Reinstall the airbox. Vacuum sync: Start the engine and warm it up to operating temperature. Remove the vacuum plug holes in each carb body and screw in the vacuum gauge adapters. Set the idling speed to 850 to 950 RPM. Adjust the throttle stop screws in each carbs to reach the proper idling speed and the same vacuum readings for each carb. Open the throttle and bring the RPMs up to about 3,000. Watch the vacuum gauges to see that the needles rise to the same position at about the same rate. Adjust the top cable locknuts to achieve the same vacuum in each carb. Check the idle again and adjust via the throttle valve lock screws. The the throttle a few times to confirm vacuum readings. Turn the wheel to check that the cables are routed and adjusted properly

Once you find headers you should definitely make a beetle exhaust straight out the back

Just a heads up kid. Those carbs won't run properly without vacuum so airpods won't work need factory air box. Or make custom one based off factory design. Good luck buddy keep up all the positivity.

I don't remember if the front wheels have brakes. If not, I think it would be a really good idea to have front brakes. That one rotor and caliper on the rear axle is likely not gonna be enough. Just a thought. I wanna see this thing rip, but I DON'T want to see you get ripped apart.

[@RealSuburbanCowboy]

Dude, you are going to get hurt with that thing. It's cool, but it is SO rigged up. For the large drive sprocket, use a round piece of steel between the 2 parts you currently have welded, and drill and tap holes to match the existing piece and the new sprocket. That way, you don't need ANY welds on it, and it can be removed. Make sure you put the chain tensioner on the lower side of that sprocket (the side that is not doing the driving). Good luck. I gave you a thumbs up for the video.
