I end up buying a very cheap Honda 400ex quad and then installing the cheapest 440cc big bore kit onto it for testing purposes. I attempt to start it for the first time. Will it run? #Honda, #Test, #BigBore,

@mikes.1706 2 года назад

Put the some cylinder on mine but I didn't use the piston that came with. I put a 12-1 compression piston in it. Also got a head, valve and cam chain all the same brand. Runs amazing. It's been a year now no issues. It works great at Glamis. Also put a 16 tooth sprocket in the front and a 38 tooth in the back.

@Savage1351 2 года назад

Hello Joe, long time viewer here. I've never commented on your videos actually but I just wanted to say that your channel is a DIY paradise. I've learned and learned so much about watching your videos the past few years. I'm mechanically competent but at the same time I don't have much confidence taking jobs on my own machines sometimes especially engines. That said, over the years, watching you tearing down engines and fixing stuff finally got me started on rebuilding my old big red 250es that has been sitting for 20+ years. I found out that the oil pump blew and fried the head. With all your knowledge and tips, I managed to find a complete used head and top end kit and rebuilded it myself, and now my old ATC runs again. I also do plan on rebuilding my brother's ktm 150sx top end sometime this winter. Again, thank you for the time you put in these videos. It helps people more than you can imagine. Cheers.

@2vintage 2 года назад

That's awesome to hear! Nothing more satisfying than hearing your machine start up for the first time after rebuilding it! Keep it up!

@powerpit48 2 года назад

I really enjoy watching you bring back a old quad. You always try to keep the cost down which shows us what others could do. Like your videos, keep them coming.

@Hanky_Bannist8r 2 года назад

It sounds pretty healthy for the most part. Proper jetting and continue break in it may just get better. I still suggest a couple oil changes during and after break in. The oil filter will tell you how well it's going... Or not lol good job Joe !

@markhensley9378 2 года назад

Great build video. Yes I think that a larger pilot jet will help with the fuel delivery. Looking forward to seeing more on this project. Hope your investment pays off and this big bore is worth the price. Would like to see you trick it out with a cam and full exhaust system. Thanks again for your time and videos. Enjoy the rest of your week.

@justinm6110 2 года назад

Sounds great bud, i bet it holds together because you checked the ring gap, most get these kits and just stick it together and dont check that and they blow up after an hr and blaime the cheap kit, nothing is more fun then scoring a cheap quad and getting it running for super cheap, another great video .

@tinybubbles3724 2 года назад

Motor sounds great, exhaust needs that end cap bad.

@lawerncemiller6557 2 года назад

Yeah someone suggested raising the needle in the carb that should get rid of the bogging just above idle making the mixture a little richer

@MM_in_Havasu 2 года назад

With a bore kit, run a size larger on the mainjet for starters and raise the needle one notch.

@shoes121255 2 года назад

I bet it blew up due to being lean since it had no exhaust end cap. I would find a slip on. The jetting specs from the HMF exhaust website should be pretty close. Around 160 main if running the airbox lid and 175-180 if no airbox lid. 42 pilot. Often times with just a big bore kit and no other supporting mods jetting is actually the same or leaner, bigger bores pull more vacuum which actually pulls more fuel through the same size jet.

@ShiningRevolver 2 года назад

I think you should get a cheap header and exhaust also since it’s a big bore give it more flow to keep from over heating

@MusicSensations1971 2 года назад

If you take a little PB blaster or WD-40 and run it around the inside of the air boot it will slip right on your carburetor nice and easy peasy

Those really are some pretty nice replacement panels not bad. Did you get the plastic welder yet? Never heard an exhaust like that before? the thing is a 440 pretty big I guess. If its any thing like a MOPAR 440 it will be pretty bad ass.

@mikeschlup5279 2 года назад

Once you ride it...and you get the jetting good, Redline 15w50 motorcycle oil or even Amsoil will pay for itself...they are the most heat Resistant and the highest film strength...take it out to your parents and run it...a fuzz rich won't hurt.

@lanceh.8537 2 года назад

Honestly, looks like all he uses is the Autojare impact wrench, and the Crescent 170 piece tool set. Occasionally you’ll see him using a 18v Bosch drill. Most of his specialty tools like flywheel puller and crank splitter are all Tusk brand suited to brand or model of whatever he’s working on. Then odds and ends whenever he doesn’t have a correct size socket or something. But between that impact wrench and that crescent set, it covers 90%+ of everything he does.

@Anticidal25901 2 года назад

Man, I’ve watched your videos for a while. Good stuff. I think I would’ve upgraded my head studs going to a big bore cylinder, also a big bore needs more airflow. Which means you should get a new exhaust with better flow. A cheap full exhaust option is resonant racing. I prefer HMF myself.

@jpc42480 2 года назад

I’ve seen people run race fuel on a stock engine and the pistons looked like yours afterwards

@tpghl5225 2 года назад

You’ll just loose power if you use too high of an octane rating. But you can run like 94 octane VP fuel or mix a small amount of higher octane (like 100+) with pump fuel to get about that octane and see some improvements to throttle response. But anything over 95 in these machines and even most stock 250s and 450s won’t lead to any benefits at all.

@garageex4491 2 года назад

Hey man I dm’d you about breaking in a piston how do I ?

@polishoskar2039 2 года назад

From what iv been told over couple of years now and from what I have read most important is wall to piston clearance, ring clearance and with 2 stroke oil ratio. Obviously you should never get China parts but since your doing it for informational purposes then I guess it's okay. I just wouldnt wanna risk anything going into the bottom end

@tpghl5225 2 года назад

Ring and piston/wall clearance is just as important. Both could lead to catastrophic failure either way if not measured and inspected properly.

@njmxjunkie3128 2 года назад

What oil did you use??? For future reference synthetic oil does not allow the engine to break in. The point of heat cycling is to allow the metal parts to get hot and harden to the same hardness all Together. Synthetic oil doesn’t allow this process, this is why brand new bikes all Come with non synthetic oil and the dealer will tell you not use use synthetic your first couple oil changes. I personally don’t believe in engine break ins and don’t think any of that actually does anything. I think the dealer suggests a break in period so that if they didn’t install anything properly that if it fails you won’t have complete catastrophic failure

@njmxjunkie3128 2 года назад

If something is wrong it’s going to break in the first little while, otherwise it’s going to last a long time, so running low temps and low rpm’s will minimize damage in case of catastrophic engine failure,
