Can you get one of those 90 degree dental picks into the hole? If so, you could attach a piece of cotton shop towel (larger than the I.D. of the hole of course) or fabric on the end sort of like how a gun bore brush works in cleaning. Either way, I think you are safe and good to go!

Russ,

I thought I may have an R6 master like that and I do but the plastic elbow is broken.   :omg:  Not by me but by the P.O. as I bought it as parts in a parts lot. But.. it did give the opportunity to remove it and see how it fits!  :olaf:  It is an interference press in fit after the circlip is removed. The lower part is smooth too as you can see in the pics attached. Also, note the last pic of the inner part at the bottom of the elbow where gunk can accumulate! Based on seeing that, you may want to remove it by taking some pliers and grabbing it below the elbow at the base of the master unit. Hope this helps..

May I ask, what is the event you are taking the bike to?
I'm planning to do this year's Rainey's Ride the Races at Laguna. Should be fun with all those legends! The TZR is my first choice for the ride but I have back-up bikes just in case it's not ready in time.

I need to have this bike done with plenty of time for shakedown runs and to put some mileage on it before the event. I don't want to be "the guy" who breaks down on a 100-mile group ride.

Thanks and damn it. I wish I would have know about that ride. I would love to do the ride. I would have altered current plans. Ken

It's starting to look like I will not be riding the TZR. My completion target date has passed (yesterday, 6/27). :'(  There's no way it's going to be ready in time due to the stuck brake pistons and this front master elbow, and allow enough time for shakedown mileage. So I'll be forced to take the FZ6.

I have another front master unit (used, but nice) on the way as a back up. Unfortunately it looks like it may not arrive until 7/3.

nope, not going to do that. The way things are going that would mean I would have 2 disassembled and non-operational bikes
