LTR 450 Troubleshooting Fuel System 

Thank you for the input. Sometimes it can be simple.

Lean for some reason possible. Check your fuel pressures. Those are good, depending on your modifications, it may need more fuel. Or some heater pipes or just thinner material and OEM.

I forgot to mention it also has a cherry bomb plug in if that make any difference

I am glad this was able to help you!

Oh yea. When it comes to electronics, I try and avoid the cheap cheap stuff. Nothing but OEM with the catering components

Thanks for the sub!

Are you sure you are having food fuel pressure. Sound like a low pressure issue to me. Mine used to cut off after full throttle. That pressure valve is what I would change but check the pressure if you can.

@@juicer911 yeah man so i actually checked after watching your vid - it holds but pump and the FPR both have the slowest drops. Are they supposed to hold the psi, or slowly drop?

@@andrewabreu6678 I’m pretty sure they should hold. Maybe the O-ring on the inside of your pump is going bad.

@@juicer911 Just dropped you an email

did you ever get it fixed dawg mine does the same thing

I would say to do the checks yourself. Don’t go based off what he said. People tend to lie. If you have done the swirl filter, delete, first thing I would do is check that filter and make sure it’s not clogged. Then Check your pressure on your regulator, remove the injector and clean it. The fuel pump is a little more difficult to explain how to repair or check. But you can make sure it’s at least getting 8 ounces and 10 seconds of flow.

I am glad it was able to help you!

Upper sensor?

Boom!

Or weak battery. Usually when is valves, it starts easy, but it is hard to start once warm.

I downloaded boot camp. It allows for a partition to install windows on a MAC temporarily.

I am glad I could help ya!

facebook.com/witherowpowersports Craig is the man!

I can’t remember exactly. But I think that they are 20s in the front and 19s in the rear.

If you are on Facebook, look Craig Witherow with WitherowPowerSports. He was my connect.

I did but you can also get them from Craig Witherow at Witherow Power Sports.

It is always good when you get these things figured out.

Glad you liked it!

Are you sure you’re using the right plug? The fuel pump and the fuel injector plug are pretty much the same

@@mrthrottle4587 it should not run with fuel pump unplugged at all.

Do you think my injector could be stuck open?

You gotta be trollin.

No? I’m for real trying to fix this thing!

time to check that fuel system!

My top end was bad 80 percent leakage wat the shop told me so I just rebuilt the whole motor

Right.

@@juicer911 is that an aftermarket or oem gut in the pressure regulator

@@juicer911 is that part you installed oem or aftermarket

The replacement is an OEM equivalent. There is not OEM gut available. The ones from Craig at WitherowPowerSports has a lifetime warranty.

If you are local, we could consider something

My ltt450 started real good and runs good for five minn then dogg as hell the ER n kill it and it runs good agean

@@onelogue hyper bead locks carbon fiber

@@juicer911love them! Thank you.

What part

I got the part from WitherowPowerSports. Craig is an upfront guy!

Nice yeah my ltr blew up on me had to a new top end and put it all back together for no pump pressure 🤦‍♂️🤣

A lot of potential issues, still have spark and compression?

@@juicer911 yee.. but still no start

I purchased my regulator from Witherow Power Sports. Craig is a great guy to work with.

hope that it fixed your issue

@@juicer911 it did

There is an idol screw on the back of the throttlebody. A flat head screwdriver should fit there.

@@juicer911 thank you
