So, I managed to get the VTR started again but then it developed the same symptoms as before so I've removed the carby's again. And, again, the slow jets are blocked but this time it seems much worse. I've had them soaking in carby cleaner for about 5 hours now but the blockage in both is still as solid as a rock. I'm leaving them overnight but I had a look at a Honda site to see if I can order new ones and, from what I can tell, you can't (at least off their website and, obviously, I can't ring them today. Are new slow jets something I should be able to source easily enough? Any suggestions for suppliers? I can, I guess, buy two carbies from a wreckers and just swap them but, as usual, cheaper solutions are more appealing Any other ideas? Silver lining is that I've taken the top of the bike apart so many times now it's like visiting an old friend
Tried unblocking them physically? Post up some photos. If they're blocking repeatedly logic says it's probably not the jets that are your issue...
Yeah, @joker, i have tried physically and, like I say, its like rock. Pretty sure I know the cause - the fuel filter (a screen in the pipe from the tap) was trashed. It looked like it got crushed and twisted at the same time so it was simply strands of screen held together by some good bits. My guess is that bits of it have fallen into the fuel line and, in conjunction with me shaking up the tank when removing it and draining it, much crap has gone through the carby. I've got a new in-line filter lined up to get me by until I can source a genuine replacement but that assumes I can get the slow jets cleared
Soak them then try to clear them gently with a thin guitar string or a bristle from a wire brush making sure it has no burrs on the ends ..... compressed air would help also. Looks like u have Keihin VD10 carbs in your bike ..... so as much as Keihin is owned by Honda u look for Keihin carb pilot/slow jets Just like the FZR has Mikuni carbs not "Yamaha carbs" They should have the size/number stamped on them http://www.showandgo.com.au/jet/jet.htm?jet_bf.html~mainFrame http://www.jetsrus.com/index.html
Thanks @GreyImport , I'll hunt around for the jets. @joker, smart plan After repeated boilings and application of carby spray I think I've got it now I'm leaving them to soak again overnight but I can at least see light at the end of the tunnel I'll put the bike back together tomorrow and let you know how it goes.
Should not have to replace the jets. They are made of brass and any thing like a wire from a brush should have them clear. Have you cleaned all the other jets and passages? Also clean the needle and seat before you put them back on the bike as you may have some crud in them that would cause them to leak.
If a wire brush bends a small pin or safety pin (being careful to ensure you don't force it through the hole and make it bigger) may also help.
Thanks guys, more carby cleaner and some air compressor work and they came up shining like new Put it all back together and fired it up and she sounds sweet and eager to go. Unfortunately, I can't go for a ride right now but I'm confident it's all good. Thanks for all your help (And, goddam, I LOVE the sound of this bike! Not sure the neighbours will feel the same way but what can you do? lol)
