Hey Greg, you going to keep the airbox the way I had it?
I think it made more airflow for the mountain and desert riding I did.
Plus it made servicing a breeze.

Greg,
Tried to send you a message, but I couldn't get it to accept GFrench--go figure. I see from this build that you are in Texas; when did you leave Colorado? I'm still stuck in California, and I hate it. I've tried messaging MarkT about taking my RT-3, but he moved, had health issues, etc. He hasn't returned my last few messages here, so I guess he's no longer interested. If you know of anyonew who'd be interested in an RT-3, send them my way. Email is This email address is being protected from spambots.

Hey Rick-

Since I have an original air box in really good shape will be putting that back into the bike...  The Uni Filter set up is Great- I have them on all my daily riders.  

But for this MX will be turning it back into orginal with the parts that I have.

Hey Hammer-

Good to hear from you again... yeah not sure why you were not able to PM me on the site here.

Yeah happy here in Texas!

Your RT3 was a good solid bike when I saw it out in Cali... I will let you know if anyone I know is looking for one... but good to have it on the site here to see if anyone is interested.

I heard some good things about this cleaning solvent at Tractor Supply-  Has anyone used it with good results?

I have been using that same cleaner and like it. It will still deteriorate nitrile gloves so keep that in mind when working with it.

Asking for a friend. ;)

My tank is not harbor freight brand but I’m almost certain it’s a clone of the same model with a different brand name slapped on it. Works just fine. You’ll need 2 jugs of the psc1000 to fill it enough to not cavitate the pump.
