It's the intake setup. Your middle 2 cylinders are cold and killing plugs because the fuel/air mix has a straight shot to those cylinders while it has to make 2 90° turns before it gets to the cylinders.

[@ronniewilliz153]

Imo there is no way it wouldn't be the cause. it has an effect on it for sure.

[@chappyboylsx2596]

@cody McGill I been trying to tell them two for a very long time that the plastic piping and 2 cards isn't going to work right on it. They can't find out why it won't run right 🤔🤔🤔

[@BSFPC]

Might also be worth mentioning that when they did use the 4 carb setup they used cheap and nasty chinese style air filter pods that are well known to cause issue with them older keihin carbs. Whack a set of Mikuni RS34 Flatslide's on that bad boy and it'll rip! (with proper manifolds ofcourse!)

[@larrydavidson3402]

Definitely agree 👌 I was going to say the same thing but happened to read yours first I just wish they would bit the bullet and put that sports bike motor on it 😅

[@Jeff-oo8gx]

Yeah, I think it'll run okay with just 2 carbs if they can get equal length intakes into them. 4 carbs would be ideal, but I can understand them not wanting to try to make that potential headache work properly.

[@davolbc]

I say pipe stack em individually four pipes straight up or maybe they have room to put a 45° for the bend to the carb.

[@lotuselanplus2s]

You guys need a proper intake manifold, the one that you have is wrecking the fuel delivery on the outboard cylinders while giving the two inboard ones a straight shot to the valves, and you really should sync those two carbs correctly.

[@hunterpetrovich1154]

PLEASE DITCH THAT INTAKE SETUP. Don't even gotta go 4 carbs. Have a plenum between the two carbs and the 4 cylinders. Plenum has to be AFTER the throttle blades.

[@izzyplusplusplus1004]

A plenum with 4 intake runners would be perfect. Throw a Holley on it!

[@heccsagone]

I missed the cross kart, so good to see it back

[@garnethart1137]

Hey guys. First step in a good tune up is to confirm compression is balanced across all cylinders. Within 10% of each other. Second thing I see is you are trying to feed 4 cylinders with half the carburaters the bike came with.now that u have a sonic cleaner surely u can find 2 more decent carbs to put it back to stock configuration. Third(and this is just my personnel opion) put some bigger tires tires on that thing! Get it up outta the weeds and make it roll over obstacles easier! Keep up the good work.i enjoy ur channel.

[@MUSKLR]

Great to see Ike back behind the wheel!

[@Review3d]

Guys, please invest in an exhaust fan for the shop! For under $200 you can put in a good wall mount adjustable speed one that just plugs into a 110v outlet.

[@dustinengel8468]

That is the perfect build for a 2 stroke 600 triple or a twin bigger. Nothing you've built is more perfect for a snowmobile motor then that

Do u really get proper ground for the plugs on that paint surface? They seem not to be in contact with bare metal.

[@300zxdriver]

@@jacobbornman9494 But these aren’t even the stock carburetors . The stock motorcycle has four carburetors.. syncing them just makes each carb open the same amount at the same time. This has two carbs that can also be synced . But I’m telling you now .. that is not why it runs like shit.

[@cavemanvi]

thanks for asking i was curious

[@Lowry7724]

@CarsandCameras put 4 factory carbs with proper filters and high energy coils. The intake setup has been the problem from the first in my opinion

[@ik04]

How do you expect spark plugs to work when they are not touching bare metal? They have to be electrically connected to the frame/engine to work,,,

[@ridefaster6802]

Exactly! At least put them on the valve covers!

[@richardwheelock6688]

A set of coils from a CBR600F2/F3 are the same impedance as the originals (therefore won't damage ignitors/spark units) but will give a noticeably hotter spark. Cheap and almost bolt-in ignition upgrade. Have y'all checked valve clearances? If that engine wasn't well maintained before you bought it, good chance at least a few of the valves are way too tight and you're losing compression (and on the way to burning a valve). Aim for ~.005" clearance... adjust by changing shims. Then do a vacuum sync of the carbs. Also... agree with everyone else commenting on the intake manifolds... no way those things are providing consistent mixture to each cylinder.

[@discipleoftheword1785]

So don’t the plugs need to be grounded to spark consistent. Wouldn’t the paint keep them from grounding to the frame?

[@NVMDSTEvil]

wouldnt run at all if there was no ground, plugs ground through engine. Their problem is the intake piping and firing order.

[@MrTheHillfolk]

They "should" ground , but have fun watching for spark with that bouncing crap allover the place. Either get a Briggs spark tester for 8$ or wrap a wire around the plug to ground it. The spark checker is way easier to deal with though.

[@NVMDSTEvil]

@@MrTheHillfolk oh you guys are referring to when spark testing against the frame. Yes, a better ground would be better.

[@MrTheHillfolk]

@@NVMDSTEvil and really , most spark checkers make it jump like .100-200 or even .250 of an inch or more. You might have spark at a plug gapped at .035 but load the coil with a 1/4 inch gap and see it fail under load. That simulates a load similar to it trying to fire in a cylinder.

[@MrTheHillfolk]

@@NVMDSTEvil 1342 it should be and ya got a wasted spark on the exhaust stroke of that cylinders running mate. Running mates , firing order , knowing which way the "dizzy" turns and you're unstoppable from figuring out any firing order ever.

[@wesleyd.A10]

You guys should put an exhaust fan and shroud in the window so you guys can keep working on projects while troubleshooting engines. I mean, it's better than breathing in all that carbon monoxide Especially during wintertime since you guys have to diagnose and/or install engines into new projects. Just looking out for your health guys!

[@connerpost8970]

You guys should check every ground I'm in a shop class and I was working on a bike with pretty much the same motor and I fixed the problem with tightening a ground

[@carbide1968]

They do sell spark checkers. Plug them in and they flash nice and bright if that wire is providing spark. Might wanna pick up 4 so you can see them all working or not. Your welcome.

[@MrTheHillfolk]

Briggs ones are nice , but around 15$ each. 2 of em would work though

[@lorenzobiundo8059]

Doesn’t matter much now, but we’re you grounding the plugs through a painted piece of metal?

[@mikedavis1751]

Guys, guys guys, please. You have 4 cylinders fed by 2 carbs. That in its self is not bad. WHAT IS BAD IS, the 2 inside carbs get straight flow from the carbs. The 2 outside cylinders have the flow forced through 2 90 degree turns. The fuel mixture is very different between the cylinders. Put 4 carbs on it! Repeat, PUT 4 CARBS ON IT!!!! Or at least a manifold to balance the carbs.

[@teebuck394]

I’m so glad that you guys decided to pull the cross kart out and do some repairs man I love the cross kart

[@keithflemingfutv3190]

This engine is supposed to have four carburetors four idle circuits you're trying to feed it with 2wo idle circuits

[@edwardweisenburg16]

Cross kart is my favorite too then the pick up kart. Cross kart needs alittle taller suspension. I'm having panic attacks waiting for another oil case fracture. LoL 😂

[@suzukiman650]

Not likely at full power when missing 2 carbs and using a janky intake manifold. Why do you not want to run 4 carbs like the engine was designed for?

[@SuperBigdanno]

Because they dont know much about jetting or the effects of a proper air box on CV carbs

[@JimmyJamm]

They could not get the 4 carbs to work way back when ad tried to simplify with two carbs. It worked until they installed this new engine.

[@crudboy12]

​@@JimmyJamm If I remember rightly, the two carb setup was an attempt to fix a problem that turned out to be caused by something else. It never seemed like it ran that great with the old engine, hence why they were so eager to replace the whole thing instead of just the broken oil pan. The issue is that they transferred the problem from the old engine to the new and are wondering why it still doesn't run right.

[@JimmyJamm]

@@crudboy12 perhaps, not certain if I really recall. Regardless I think they are tired of trying to fix junk and are wiling to pay for a decent motor now.

[@forrest6132]

It might be time to take the hit and get a new set of stock carbs for that engine.

[@1982HondaATC70]

24:15 your left side carburetor is completely missing the brass cable adjuster on the top cap. From the looks of it your right side carburetor slide will move 1/4 of the way before the left side even starts to move. There is also going to be an air leak from those areas since you aren't using the rubber caps that go over the cables.

[@noduh736]

Or you could just put the stock intake and carbs on it I'm sure it's the mess in that area causing problems

[@tomstech4390]

23:15 I think you need better front coilovers with more travel and a higher springrate to prevent the front digging in, Also that left front hub could do with some work too looking at the camber angle.
