Update.

Been discussing with Billy C (V4 carb rebuilder). He is in for 10 sets if he can be convinced that the replacements will work. We've been looking at different things, and think we've found that CBR900RR and CBR600F3 (among others) share the same diaphragm. We are going to see how close F3 pistons are to the VFR ones. If they are similar, this opens up a bigger market for JBM industries to serve. We are just on the borderline of making the 30 minimum order, so this might be a reality after all!

mmmmmmmmhhh

AFAIK, they are not the same. These pistons are only used in the 4th gen VFR. That is by going off of part numbers in the parts catalog.

He might have one that fits. that might be the same as the VF700C, which he has listed. K-68. Send an email, pictures, and dimensions, and he should be able to let you know.

Last bump. Setting Oct 1st as the deadline.

I'd buy it and have no qualms about binning it on the track

Fixing picture links would be great.

So...looked through the thread. All the pictures are still there. Can you not see them?

Here's the link to the new album if that helps

Bumpity bump.

No other 4th gens want some fresh rubber in their fuel control system?

@BiKenG I didn't have a Triumph wheel to measure the offset. Just the loaded swingarm. Send a PM if you still need info.

Maybe I'll make it a weekend project to fix all the picture links. I'm running my own image server so they shouldn't break in the future.

I went with a full length one and remove the insert in my 2-pcs. I run the Tryonic and it's pretty comfortable under the jacket. Don't really think about it much.

RevIt also makes inserts that might fit.

Looking to put together a group buy for replacement 4th gen carb vacuum pistons. These are the rubber diaphragm  that moves the needle up and down. You cannot buy OEM replacements, and I'm not sure if you ever really could. If you have a torn diaphragm, or yours are just old and dry from being 20+ years old, this is for you.

I met with Paul from JBM industries. Paul manufactures OEM replacement parts for many carbureted bikes, including isolator boots. Mike Norman used them on his NC35, and if they are good enough for him, they must be pretty good. He is confident in being able to make replacements. Because these diaphragms are only applicable for the 4th gen VFR, he would need a full order to cover his costs to make the initial batch. If you know other bikes that use these same diaphragms, let me know.

Only the rubber diaphragm will be provided. Read through JBM's page on replacement instructions, but these will involve clipping the plastic ring off and gluing the new rubber on. He will mold in extra thickness to have the rubber replace the ring, as he has done with over parts. If you are not confident on replacing them yourself, we can work on having someone replace them for you.

I will be providing a sacrificial set of parts for him to do his prototyping on if we make the orders.

For Paul to go through with this, he needs a commitment of 30 sets at $80 per set of 4. This does not include shipping. He normally handles production of new molds and products at the beginning of winter, but will confirm if we get sufficient orders. Sign up, ask around, lets see if we can make this happen. I'm starting off with 3.

Give the KOSO heated grips a shot. You have to give up having your choice of grips, but the heat from them was amazing last time I got to try them.

Did mostly commuting on my old VFR. Took it to some real twisties with the tires for the first time. Front was sorta cupped and rear had a flat spot. Definitely could feel the bike get all upset rolling over that part of the tire. In the garbage they went and fresh stuff on. Not worth having that on your mind while you are riding.

There are people on here who could do the work for you if you don't have a dealer or service dept you trust. @SEBSPEED

Those aren't issues that you wouldn't have on any other bike. The way you should look at it is like this. "I have a bike that is old and hasn't been completely maintained. Should I pay for someone to go through the bike to make sure everything is in good shape so I don't have to worry about any safety issues with the bike anymore, especially since I am riding with my daughter, or get another used bike that probably has the same issues." I'm guessing brakes and clutch have never been touched. I would get it done sooner than later.

Again, reiterating safety issues with having fully functional brakes and good suspension. Honestly, I would look into a replacement rear shock too since that thing is most likely toast.

I would say that something is still off with the carb cleaning. I don't think I've ever had to pull the mixture screws out on any carb to get it working right. Are you sure your floats and needles are sealing? Absolutely sure the pilot jets are clean? Are your coils grounded properly? Does it run if you give it throttle.

Off subject, but did you check quality and quantity of oil and coolant?

Just saw someone sell an RC45 for $35k.

Really?? a tad high? ,find me another one that nice I’ll pay double that ,,I looked for over two years and all of them had issues or were rusted beaters! The mint stock exhast is worth a grand!

There is a guy on the WERA forum selling a pristine 1986 VF1000R for $6k or thereabouts. He seems to have been a serious collector, but is selling off his collection of 100 bikes.

@mcrwt644 might be a bit closer to you if you want someone to work on them.

Agree that it sounds like a float or needle valve issue. Once upon a time I had a service guy install the floats upsidedown/backwards, so they never closed right.

That's a good looking helmet

I don't blame you. Finding a green one AND the 4 cylinder version is pretty special. The 3 cylinder one sounded better but wasn't as fast.

Funny enough. Harley recalling a TON of bikes for brake fluid. 

https://www.asphaltandrubber.com/recall/harley-davidson-brake-bleeding-recall/

I think part of it is that they use two different grades of brake fluid for the clutch and brake, or the front is different than the rear, and that perhaps even some dealerships may have mixed them up. If that's true, then you will have some serious consequences. But it's pretty stupid from the start to require two different grades of fluid that aren't compatible on the same bike.

There is a V1000 convert project with full touring set f/s in the cleveland craigslist if you need more guzzi in your life.

Most of them are rotting away, awaiting the decade when I'll get to work on and enjoy them
