Just picked up a 2006 LTR also. Got it for dirt cheap but wasn't running or turning over. Ended up only being a faulty tether kill switch. By passed that and went back to the original wire setup. Finally got it running but it's doing exactly what yours is. Before I bite the bullet on the injector I'm going to cycle some injector treatment into the lines and see if I can get it to clean it out. Also, I'm going to make sure all my sensors are clean and what not. These things seem to have a crazy amount of sensors/electrical issues. Can't complain for the price but it's still rough on the edges. I'll let anyone else know if my injector idea works.
I just fixed mine. It was doing the same thing basically. I replaced the fuel regulator. I also put new gas in it, make sure to use 93 octane! Now it runs like a champ.
Fuel filter /swirl in LTR450’s are always clogging up. Maybe clean ur intake n throttle body real good, and check the injector? Hope you find out what the issue is. Good luck.
The fuel pump must be opened clean out the filter underneath proper, the Tea bag under the tank itself must be cleaned and blown out nicely, then lastly remove the injector and make sure its cleaned out nicely, also try give it a bit of Fuel system cleaner in a small bottle that you can apply pressure to, and then pulse it with 12volt till you see injector basically sprays out nicely! Then assemble your prob shoulf be gone.
Ltr’s are known to have fuel problems. Mine did it and it ended up being the swirl filter which seems to get a lot of people I just removed it and replaced it with a Spectre in like filter and runs fine now
Did u ever fix the promblem my sputteres and loses power under full throttle in first and it’s like gestating then has power then hesitates. Only under a full throttle
For future reference I’ve had 6 of these in the shop and the injector screen was always the culprit and is the easiest to see if that’s clogged before you start taking other things off
Mine just did this after tearing it down, cleaning it, and put new gaskets on it because of a oil leak. The yellow wire at the tps sensor ended breaking off when I removed it and didn't pay attention to it lol.
Mine would start but not accept throttle replaced fuel pump injector swirl filter clean throttle body and runs perfect now also added Yoshimura peripheral interface module
Did you at least get it for a good deal ?btw subbed like your channel reminds me of my past year with different dirt bikes lol I’d recommend doing a compression test to at least see how the motors doing.
i now its a little late now amd youve propably already fixed the problem but mine also did that and if you look inside of that thing under the gas tank by that you said leaks petrol when you turn it inside that thing there is an tea bag filter clean that filter up because there can be a lot of dirt and junk even rust in there. And idle srew is behind that feul pump mine has keinin filter on there hope it helped🙈
I hope you got a good deal because you didn’t check it over worth shit before buying. Check fluids, start cold, ride through all gears at all throttle positions, run till fan comes on, turn off, start back up.
Fuel injector you can clean it it. take it out blow air into it from the bottom up. also you can adjust the idle with the throttle cable at the thumb throttle.
That is absolutely the wrong way to adjust your idle by the throttle cable that's how people end up getting killed the idle adjustment is on the right side of the throttle body where that plastic cover goes over the throttle cable
It's the fuel pressure regulatortake it off blow it all out clean it all out and that will most likely solve your problem check your fuel pressure if your fuel pressure is anything below forty it's either your fuel pump or the regulator but it's most likely the regulator had the problem with mine beat my head on the wall for a month trying to figure it out and then came across the post one day explaining how to clean it and I did that put it back together in the bikes never ran better
That's not the idle screw the idle screw is on the right side of the throttle body where the throttle cable attaches the one that you're using to raise or lower the idle is the air screw so I did the same thing on mine but if you get that out of whack it will start hard if you have it shut too much so again the throttle adjustment is on if you're sitting on the bike is on the right side where that plastic cover goes on there's a set screw that goes up from the bottom that's your throttle adjustment
@@lildave4954 sorry throttle body the screw that you are talking about that is not the idle screw that is the air screw the idle screw is on the right hand side of the throttle body on the bottom side of where the plastic cover screws on there's a set screw and a jam nut that is the idle screw the one you're talking about is the air screw which should be out two turns
It's Me Mikey check your battery, i had a problem with my 09 ltr 450 . needs to have like 12 volts or 14 not sure, but i replaced the battery and ran like new.
weak fuel pump bad fuel pump dirty injectors dirty air filter oil to full the airbox sensor is dirty sucking air through head gasket or exhaust flange.. faulty weak battery timing off valves out of clearance ltr450rs are a pain in the ass Been there done it...
Wow that doesn't sound good, I plan on selling this one in spring because I will be getting another dirt bike for the summer and then in the fall getting another four wheeler to go along with the bike
Bad gas can cause a crap load of issues with an ltr fuel system. When moisture gets mixed with fuel that contains Ethanol it causes it to separate out of solution and creates a florescent yellow elephant snot kinda gel that will sink to the bottom of your tank and plug up all sorts of strainers and filters.
Same thing happened to mine. I have a 2007. Ended up replacing the injector and fuel filter. Ran perfect after that runs strong now.
Yeah, I ended up replacing the injector and runs great now.
250R OTM how much did you buy the quad for?
Oem injector or ebay aftermarket?
@@LegendKB1_33 eBay aftermarket. Zero issues

Did the injector work?

The idle adjustment is on the throttle body check that the cold start cable isn't broken.

Did you figure out your problem???
had the same problem changed the spark plug (5.00) fuel filter delete (27.00) and injector (190.00) runs PERFECT now
How does a fuel injected bike have a choke? Mine is a 06 LTR and I don't have a choke.
TheRobbyK its not a true choke. It gives it a slightly higher idle on a cold start
I don’t have that either I have a 06
TheRobbyK It’s called an enricher. Not a choke his bad for misleading you
For future reference I’ve had 6 of these in the shop and the injector screen was always the culprit and is the easiest to see if that’s clogged before you start taking other things off
How
How can you check if it’s clogged?
Throttle position sensor

Thanks man, and yeah I didn't lose any money on it and I got it fixed, the injectors just needed to be cleaned.

Mine takes just under 4 qts of oil . 400ml in the case and fill it till the dip stick in the reservoir
Way to much oil 1200ml in the tank and 400ml in the clutch case....
I hope you got a good deal because you didn’t check it over worth shit before buying. Check fluids, start cold, ride through all gears at all throttle positions, run till fan comes on, turn off, start back up.
what year is this ltr?
Hi, I'm from Argentina and I have the same problem. Did you find the fault? what was it?
did u ever figure out you?
Injector
Your video made me motion sick.
Lol
This is exactly what my 06 is doing
its the injectors you might have to get new ones
I'm pretty sure it's the flux capacitor😂... It's 100% your fuel injector or swirl filter
Choke might be stuck
It's the injector just replaced mine runs mint
Do a swirl filter delete as well run a inline fuel filter
Did u ever figure out this problem...I'm going true the same thing now with minds.

look past the fuel pump, youll see the idle screw, best to use an long screw driver
That's not the idle screw the idle screw is on the right side of the throttle body where the throttle cable attaches the one that you're using to raise or lower the idle is the air screw so I did the same thing on mine but if you get that out of whack it will start hard if you have it shut too much so again the throttle adjustment is on if you're sitting on the bike is on the right side where that plastic cover goes on there's a set screw that goes up from the bottom that's your throttle adjustment

The air fuel mixture also sounds off. I'm guessing valve adjustment or have someone adjust and clean your carb
David H it’s fuel injected
TPS sensor
I got the same problem with my ltr 450 06
It's Me Mikey check your battery, i had a problem with my 09 ltr 450 . needs to have like 12 volts or 14 not sure, but i replaced the battery and ran like new.
it had ome year old gas too cuz it was sitting for awhile since last summer and thought it was but i left the gas in the cuz it smelt strong still .
It’s the injector
weak fuel pump
bad fuel pump
dirty injectors
dirty air filter
oil to full
the airbox sensor is dirty
sucking air through head gasket or exhaust flange..
faulty weak battery
timing off
valves out of clearance
ltr450rs are a pain in the ass Been there done it...
Wow that doesn't sound good, I plan on selling this one in spring because I will be getting another dirt bike for the summer and then in the fall getting another four wheeler to go along with the bike
Stacy Clayson doesn’t mean I don’t love mine lol even if I gotta fix it
Idle srew is actually on the injector
throttle cable could be off or maybe even idle is off.
I'd say adjust the idle
when you give it gas make sure it is slow and consistent
choke could be stuck thats what it sounds like but again find the idle screw
Choke is get stock.. inside the cilinder.. mayve rosted spring.
You can hear it right away replace your injector fool
still having the problem
i can help u dude these people on here are not very smart
i can help u been working on my bike for 12 years
I'm having issues on mine
Can u help me lol
isaiah arias I could use some help on an 06 LTR if you have some free time man haha
Get a cherry bomb. Helps it get more gas
Huh
If you have a yoshi cherry bomb remove it... that will cause it. They are not worth running
Fuel pump
Fuel filter
pretty sure it might've been the battery.
Valve's homie
Swirl filter is clogged.
I am the one who traded you. And I told u it was bad gas. Wasn’t lyin

When moisture gets mixed with fuel that contains Ethanol it causes it to separate out of solution and creates a florescent yellow elephant snot kinda gel that will sink to the bottom of your tank and plug up all sorts of strainers and filters.
There is no choke it's fuel injected sounds like engine problem
Change fuel filter
ever think about cleaning the carb
Its fuel injected...
LOL ITS FUEL INJECTED DIDN'T YOU HEAR HIM SAY "injector"
Lmfao no carb jack ass
I just got a fuel bypass
Needs new wiring
Injector
That was full choke
Smart
Clean the carb
Might need to rebuild it (the carb) and or valve adjustment
David H it’s fuel injected
It's clapped, don't get a Suzuki...

My ltr runs strong as fuck. Had fuel problems but will blow any other 450 away.
Stephen Matinsky honestly🤦🏻♂️🤣
