Hey brother I have two brand new 2.5 20" king coilovers with piggy back reservoirs they're still in the box I paid 3000 five years ago I would take 1800 for them they would be perfect for the back of your machine

[@atsekjoker]

this looks awesome ! white spark plugs means it is running too lean. open airbox and/or open exhaust need other mapping for more fuel. lean engine will break in a moment. put stock exhaust and stock airbox back on and try again

[@CorndogBrownie]

I’m not worried about it not running right, or whatever, that’s what projects are about. As long as we get to see updates, I love it. Can’t wait to see this thing properly tear shit up

[@Hellsong89]

Well i would be pretty damn worried when plugs are white. Its running lean and thats one expensive "whatever". Running rich would be not immediate issue, just lots of carbon build up and poor fuel economy, but lean kills engines fast.

Whiteness on the plugs means their overheating which is usually because there's to much oxygen & not enough fuel inside the cylinder. Put your needle in the carb up 1 notch to allow more fuel in 👌 Hope this helps

ya might have better luck with a spool rearend on that beast ?! think thats how they came from the factory but the way ya got that set up chrome moly steel is the toughest material they make for a live axle application your working with 🤷‍♂️might be wrong just a suggestion for future reference brother ! 👍

[@DktheWelder]

A spool is for a diff on like a north south motor. This is just a live axle like on a quad, it is induction harden chrome bar which is the hardest you can get , chrome moly one would be a bit lighter.

Gday mate just a heads up i had a 1998 model TL 1000 s which i used as a courier in Mel city and i did the same mod with the exhaust you have done 2 into one and had th same running issues. switched back to twin exhaust and it ran much better. More fabrication but well worth trying. good luck bloody rippa project.

[@DktheWelder]

It could be but I have had it running well with this setup before

[@aspopulvera9130]

The design and the wheel size looks like a mini tumbler batmobile

[@GeorgiaRidgerunner]

Those frosted plug tips are caused by a lean run condition is caused by an improper by an improper air to fuel ratio (to much air) you probably have a leaky gasket some place in your fuel system Its possible your fuel system pressure is low (Bad pump bad hose) Could be a hose that has swollen on the inside and restricting fuel

[@bloodsweatandtearsforeverl9833]

You can add gussets or triangle reinforcement on the axle

[@nicolec7290]

That is the best set up ever

[@XJRRIDER]

white plugs means its lean , reason can be the open exhaust - put a OEM or muffler on it with a DB Killer in it then there will me more back pressure. if you want to keep the open exhaust you need to tune the bike on a dyno probably with a Dynojet kit or something like that from another brand.

[@tylerwatts1004]

That axle looks much better. Shame you anealled it like that and had to drill the hole through, but it's thick walled so hopefully it will hold up.

[@valveman12]

Looks really cool. No rear differential? That must be a little bouncy turning corners.

[@Todd66]

Sure looks cool. Solid axle should be fine as long as you are off road. Those tires look like American Sprint Car tires.

[@DirtWAGN]

Not sure if you got things sorted, by my thoughts for it leining out could be you need to earth the motor and ecu to the frame. Also throw a bike fuel pump on as it may be to do with your tank placement. Good luck

[@Naferner_Said]

i think the fuel pickup in the tank might actually be the problem. Atleast im guessing you dont run a fuel filter on it? If you do that might also be the problem. But 1 of those seems to be blocked or partially blocked. It seems to run okish at first, and then when you put your foot down in runs out of fuel after a few seconds. So i would look in that direction for the problem.

[@DktheWelder]

Yeah it just has a filter around the fuel pump inside the tank , it is happening exactly as you say like the fuel can’t keep up

[@njmxjunkie3128]

i've got a spare gl1100 engine lying in my garage. i think i see it's next life. now all i have to do is cut down one side the the rear axle from the old mitsubishi mighty max sitting in the weeds behind my garage to match the output shaft of the engine. are those dirt track race tires on the rear? loving the look of those meats. ahh, the meaty goodness! lol.

[@victoryfirst2878]

Just want to make a comment on the axle shaft. The best material for the shaft is titanium period. Half the weight of steel with twice the strength easily. This is definitely the way to go. Another method is to get a used kart shaft which is hollow from Kart classified or some four wheelers with the tapered turned shaft ends. They can be had from junkyards all over the country.

[@SilvaDreams]

Titanium isn't half the weight, it's maybe 45% tops if pure titanium and most good steels will be stronger than even titanium alloys. Titanium mostly excels where heat is involved, though as an axels it's not going to really matter weight wise verse the weaker strength and cost. Specially since a single 1" diameter by 1ft length rod would cost nearly 200$

[@victoryfirst2878]

@@SilvaDreams You are correct, I was just taking a number of the top of my mind. But 5 percent off is not bad for just pulling out a number from ones head. Am off with the strength statement between steel and titanium. Please do not throw stones fella. I live in a house with windows. Way better strength to weight ratio. Way better in the heat department. I have a few shafts for axles lying around so to me price is not a deterrent. Would be willing to just grab a 1 1/4 inch diameter shaft and go. But you are correct when buying new the sticker shock is hard on one's wallet. One last thing Silver Dreams, I prefer the natural gray color of Titanium over rusty red steels. Also have inconel shafts too. They have been laying around for twenty plus years. Peace VF

[@safetyst3ve23]

You could have did a cv axle with a possie rear end and still achieve the same thing but with better rear suspension because it would be independent, like a cross kart

white frosted tips mean Lean fuel mixture. too much air not enough fuel. makes power but too much heat. either clogged fuel system to some degree. ORR a air leak/ vacuum leak drawing in more air After the Carbeurator. btw first time ive had a creator Reply, let alone acknowledge anything i said, Mad respect for the engagement. Hope you get it Running Right. If you watch any of JunkYardDigs (i do not personally know him) he goes over a ton of tricks with carbs and shit, dudes a mad scientist and making it run with no new parts sometimes lol. if its fuel injected. check for proper fuel pressure, or just increase it if all else fails. causes more fuel out the inj per programmed duty cycle. like a cheat way to richen or lean without actually fixing shit. increase fuel pressure by restricting return line, more,, or completly another good trick. spraying carb cleaner or either around intake connections, vaccuum lines, inj seals or other sealed air components between Carb/ Or MAF (air flow sensor) and listening for engine idle change can help locate areas that are sucking in air. GO backwards. use a vape to smoke out the air intake system heavy and a flashlight. may see smoke exit leak areas. hope im of some help, Stay safe out there in aussie land. its all coming to us soon enough :-|

[@2LateIWon]

white tips on spark plugs its running to lean.

[@maxhartry6807]

Agreed running lean seems to be likely cause. Fuel injected you say. Is it a smart ecu as in learns itself or do you programe? You need to get more fuel in it. Don't run it hard if it's running lean. I'm a 2stroke man but I'm sure it won't do 4stroke any good. Aesthetically, living your work. Looks awesome. Massive potential here. Get that engine singing before you move on. Sound

[@maxhartry6807]

Right, is your fuel gravity fed or fuel pump. When it took the tree down it showed it has plenty of power and torque. So it runs in short bursts correct. But quickly starves of fuel or loses power. Have you checked the fuel cap is venting correctly. Had this a few times where tank vent was blocked and created vacuum preventing fuel flow. Just thinking of easy things to check. Love the look of this. Really compact. I've got a 600cc bandit engine I'm planning on building into my own crosskart. Hope you get yours sorted.

[@Hellsong89]

Would not be bad idea get them checked/clean them properly just to be sure that potential issue is removed. Other thing might potentially be MAP sensor if its blocked or faulty. It would be giving less air data to ecu witch would give less fuel causing lean condition. Of course there could be air leak after the MAP sensor again giving false info on how much air goes in and then there is clogged up fuel lines, blocked fuel filter, crap in the tank, damaged or blocked fuel pump.. really number of reasons.. this is why fuel injection is horrid. Lovely when it works but horrid to repair comparing to carburetor.

Before I watch again . If it's carbs the floats are overly low so starving for fuel. If injected there is sensor problems making the ECU lean out the injection. Could be oiling up the cat.

Does that have a brain box for the fuel injection, you likely are running 2 lean, with the mods you made, and the computer needs adjusted for those mods. And as others mentioned, replace fuel filter and you may have to replace or add a furl pump, that tank may have inside of it a tilt shut off, it looks pretty angled. Some of those were designed to shut off on tilt, to prevent fire. The pumps may be causing that to shut off. Just tossing out things to look at.
