Throttle Body Cleaning - ZR 600 EFI

I have the throttle body completely removed.  It was not too difficult.  Remove a few cables, and it was done. Especially since I had already removed the feul lines. I am going to remove the fuel injectors next as I imagine they are pretty gummed up after all this time.  Then I will get down to cleaning.

Happy Holidays

Well thanks to the holiday I haven't done anything.   Been riding the phaze a bit...Seafoam has helped clean some gunk out of the carbs and make it run a bit cleaner, but it dies as low-end.  Either the pilot jets, or even the pulse line.....We will find out tomorrow as things get back to normal, and hopefully back to the cat on Wednesday,

Wednesday 12/23/2009 - Project Arctic Cat / Yamaha Phazer

Whew...I managed to get the Phazer to where it now has spark when it should.   Now I have to figure out why there is no fuel.   The fuel pump, I believe, on these machines are vacuum driven, so there should not be any electric involved.  I am surmising then that the vermin chewed through one of these hoses.

Tuesday 12/22/2009 - Project Arctic Cat derailed again

Psuhed aside again....I went to get our other snowmobile, a 1995 Yamaha Phazer, ready to go for the impending snow, but alas, my intentions were foiled by vermin, mice to be exact.  I lifted the hood to check the fluids, and was surprised to see mice condos, everywhere, albeit full of vacancies.   After cleaning out the old nests I discovered that the mice had been feasting on a few of the wires and hoses.   Hopefully all it will take is a quick patch job to get this one going.   It's too bad, while this machine is not pretty, it has always been a good runner for us, starting on the 2 or 3 pull.  Let's hope I can get it back to that status!

Monday 12/21/2009 - Project Arctic Cat ZR 600 - Removing the throttle body

The two main fuels lines were replaced. Not as hard as I thought it would be.   I connected the engine side of the old supply hose with a barbed fitting to the end of the new fuel line spool (about 10 feet of it) and just pulled it on through from the fuel pump side!  I suspected the hose clamps may get snagged, but not an issue.  I did this with the fuel pressure line with the same ease.




Now, during this and the fuel pump test I noticed traces of corrosion in the throttle body openings.  That will be my next task, remove the throttle body the rest of the way and clean it thoroughly.

Fuel Lines - Project Arctic Cat ZR 600

Who would have thought it would be difficult to swap fuel lines?  With minor effort I was able to pull them off the throttle body for the fuel pump test, but pulling them off the fuel pump was a bit more challenging.  I ended up carefully cutting the hoses with a box knife right at the ends, and then they easily slipped off.  If you do this just be careful not to scour the metal nipples that the hoses slip on to.

Project Arctic Cat ZR 600 - Lost a day

So much for today, between my real job and things to do around the house I never had a chance to touch the machine...and it's frigid out in the garage right now.  Hopefully tomorrow will see some more work performed on the machine.  Good night all!
