Member Contributer MadFrog Posted April 12, 2023 Member Contributer Share Posted April 12, 2023 I had to take a 3 year break from riding in order to get neck surgery and both shoulders and biceps repaired. Old age sucks. The only things i have been to do for the VFR have been to get her plated as an antique and keep the battery on the tender. i started her last weekend and i think im going to have to once again rebuild the clutch slave cylinder (i just rebuilt it 3years ago shortly before i parked the bike) - is that a common issue with bikes sitting too long? Also, i have been bugging the folks at NRP in the UK about making diaphragms for the 4th gen since 2019 and they keep telling me they’re “looking into it”. are there any other options? When i rebuilt the carbs last time i had to buy some used diaphragms/slides off ebay and they were ok but wont last forever. thanks! Link to comment Share on other sites More sharing options...
Csper Posted April 12, 2023 Share Posted April 12, 2023 Not sure about the clutch slave cylinder, but you will want to run some carb cleaner and get the old fuel out if there was any left in the tank, check hoses and such for the fuel system, also check for rust in the tank. All that is if you left fuel in the tank but if you haven't you still just want to give it all a good look around. Might already know most of this but a reminder cant hurt. That's all I got but I'm sure some more knowledgeable people will come along. Link to comment Share on other sites More sharing options...

Who are you?! In the minority, that's for sure. I'm a little surprised that a rebuilt slave would leak after 3 years with all fresh fluid. But usage is better than sitting on those systems for sure. I'm going thru a 92 VFR right now that sat outside for 3+ years under a lean-to, and (the non-rebuilt for sure) clutch system is still working fine and not leaking... shit... I should have never said that. I'm fucked. Link to comment Share on other sites More sharing options...
Member Contributer MadFrog Posted April 13, 2023 Author Member Contributer Share Posted April 13, 2023 Yeah, i am a little surprised as well! I have had that bike for 17 years (shit, 17 years?) and 5 years ago i had to rebuild both master cylinders, 3 years ago the clutch slave and now again. And i had used all Honda parts. Oh well. Its just the bleeding that can be a pain. any info on the carbs diaphragms from anyone? I see some one from china is selling a kit on ebay but as cheap as it is i am a bit leary of what i might get.

Member Contributer Captain 80s Posted April 13, 2023 Member Contributer Share Posted April 13, 2023 I would roll the dice on another used set before I spent money or time on some chinese diaphragms. BUT, if you can buy 1 and it was cheap enough, it would be interesting to see if they are even correct and what the rubber feels like. Link to comment Share on other sites More sharing options...

Member Contributer Thumbs Posted April 16, 2023 Member Contributer Share Posted April 16, 2023 Just seems to be seals and O rings, no diaphragms Link to comment Share on other sites More sharing options...
Member Contributer jefferson Posted April 16, 2023 Member Contributer Share Posted April 16, 2023 Couple of places advertise in the VJMC magazine that may have what you need. www.jbmindustries.com and www.Moto-Vintage.net. They are least as far as I know here in the states. Link to comment Share on other sites More sharing options...
