Quote from: MarioR on September 10, 2025, 08:01:05 PMLet's say you have pilot jet channel plugged , idle fine but doesn't go smooth to rpm. How would you clean such a small channel manually vs ultrasonic cleaner?

When you say idles fine, do you mean while on the choke? Or does it idle fine warmed up and off choke? Very important difference...

I would fix this by (cleaning them as discussed with a proper sonic soak) or replacing them for new ones, jets or carbs.  You could use some carb cleaner and copper/brass wire strands. But this rabbit hole is just as busy and labor intensive as the proper way. And you might not get it all for the effort. If you really have no options, break out the toothpicks and carb spray, and pray for the best. RPM can do a proper refresh on your carbs. Once the carbs are clean, keep them clean by running the bike frequently (every 2 weeks seems to work for me) to flush the Ethanol fuel from causing the plaque. Or drain the carbs after each ride, or use on-ethanol fuel. The ethanol is Bain   to our Kookaloo...

This was only example 

Goint to the topic, no choke, idle fine, hesitate to go from idle to mid range, after mid is going fine...

Welcome to the FJ family. You'll get plenty of help from the guys here if you get stuck.

3 of us ride our FJ 1200's to Poland in June and made sure we went to the Gorzow Wielkipski round of the Speedway World Championship races. A brilliant event with such friendly people. We loved Poland.

Quote from: Billy Bananahead on August 27, 2025, 05:01:16 AMI would consider cleaning the carbs myself by hand. Those ultrasonic cleaners will never get the carbs thoroughly clean.
In all the years that i've been biking i've never had a set of carbs cleaned ultrasonically.

Let's say you have pilot jet channel plugged , idle fine but doesn't go smooth to rpm. How would you clean such a small channel manually vs ultrasonic cleaner?

As the others have said plus i'd fire loads of cleaning agents down the orifice's such as carb cleaner, brake cleaner, electrical contact cleaner, petrol, anything that is going to shift the caked on sh!te, then put the carbs back on and fire it up. Yes i know certain agents can damage rubber seals and o rings but if i can get away with it then that's great.

The way we used to do it before ultrasound.

Carb Soak and compressed air with a needle tip.  (Wear safety glasses)

Quote from: T Legg on September 10, 2025, 12:10:24 PMMy son Ian and I from Reno are planning to give it a try also. since its an open bike rally I'm going to invite my nephew from Petaluma also. I'll be bringing my black fj1100 I took to the Hayfork rally (I put an xjr 1300 engine in it since last time) Ian will be on his ZZR1200 again and my nephew if he comes would be on 700cc something or other. Its tempting to try to figure out how to bring our dual purpose bikes as well. I have an old yamaha xt550 and my son and nephew both have yamaha wr400's.
Ian and I took a trip through there two years ago but a little further on to Fort Bragg.Then on up through Legget and it's redwoods then up through the avenue of giants and more redwoods then inland past hayfork accross to the feather river canyon section and Quincy then back down to Reno.I'll try to shrink some pictures soon and post them.

Really would be great to see you guys!
Definitely bring anyone who wants to come, on whatever bike they want to ride.......

Kudos! Another FJ on the road....right where they belong.

Cheers

Pat

I will agree with Pat

Yes Pat. This is on the list for the next step to check. Thank you
