Bad Injectors? At a loss for what's wrong with my 2008 RMK 700

[jman94]

My 2008 rmk 700 Is still bogging out and I am now out of ideas. Maybe yall could help? It started last season, wouldn't pull revs and would almost die if you have it too much throttle too quickly. Took it into the shop, noticed the clutches were in major need of a rebuild, checked compression and it was low on the left bank so we replaced the pistons (scarred pretty bad) while we were in there. TPS sensor, fuel filter, and fuel pump were all replaced as well...

Picked it up from the shop a couple months ago and got the "itch" to smell some two stroke fumes. It took probably 10-15 pulls to start, which is abnormal for it. Once it started, check engine light came on blinking and it was back to bogging under load. If I hit the throttle from idle and just falls on its face. SOOOO now I'm at a loss, could it be the injectors failing? and If so, how can I check or replace them?

Edit: Here are links to my other threads about this issue.. I;ve tried all the suggested "fixes" to no avail.

Good chance of if. Pull em and get them checked.

Were the reed valves ever checked? Hard starting makes me suspect base-line TPS setting is incorrect.

I'm not sure if the reeds were checked. I'll check the TPS tonight, but I doubt that would make it throw out a check engine light?

check with the auto shops in your area see if someone has a ASNU injector machine ,
they can test and clean them for you .
If no one does pm me I can do it for you

On the check engine light problem make sure all sensors wires are plugged in securely.

Simple to clean the injectors yourself. 6v battery with plug in, brake or carb cleaner spray and air compressor with air spray fitting.

First thought was fuel pump as the can go bad and cause lack of fuel flow and bogging out

Happen to have a picture of your setup?

I have the top two injectors out of mine but the bottom two look like the engine would have to be removed to access the retaining bolts.

Just an update... Think I've found the problem. Collapsed fuel line leading to the fuel injectors!

I rigged up a way to use the fuel pump to pressurize the rail with injectors included and I can fire an injector at a time to make sure they spray evenly. I suppose a shop could flow rate them but this makes me think they are all working on my CFI-4.
