Gen 2 carb slide question

When I got my bike the po had taken the carbs completley apart and they were in a big tupperware box. And I mean he took them completely apart!

Well with the service manual I was able to get them all back together and figure out the all the linkage. But the one problem is that I do not know which slide went with what carb. And the service manual states DO NOT MIX THEM UP. What to do? They all look the same, needles are all the same, so what is it.

What should I do. I am just about finished restoring the bike and should have new intake manifolds tomorrow so I will be tuning/sinking the carbs this weekend. Is this issue going to screw me up?

 

Only way I could think would be to try to match up wear marks on the slides and carb bores. Make sure you get the springs in correctly where the carb throttle linkages meet and adj.

 

Thanks captb. The tension springs for the linkage is all sorted and works perfect. Schematics and the service manual helped to get them back together right. In fact the carbs are on the bike and the bike runs ok but thats about it. They need to sorted out better but they are a pretty basic carb. Nothing like Kehin FCR's. Jetting is all stock per the manual spec's. So it should be in the ball park. The bike does have a Kerker 4-2-1 pipe and I bolted up a Delkevic 13" Tri Oval silencer to replace the mickey moused Yoshimura silencer that was on it. So not sure if I need to rejet but I am thinking I won't. But any input on this would be helpful.

 

Mines stock jetting but I've modified the stock cans and have a K&N filter, it runs strong but I would say it's still slightly on the rich side especially compared to most Jap bikes that are usually fairly lean stock jetting. Does yours run better cold...usually rich in that case. If it seems better hot it's probably on the lean side. If it seems rich you could try shimming the air box cover up to let more air in and go for a ride, if it's better someone may have jetted it too rich. I have the FCR on my DRZ400E, it just sat for 3 weeks and the bowl gasket weeps now, probably the needle/seat O-Ring shrunk too it's running richer so I think the float level is higher due to that o-ring. I'm glad I don't have 4 of those on VFR, I did a MRD SSW exhaust and removed the snorkle on the DRZ, rejet, played with the needle 5 times and 2 accelerator pump adjustments, it came to life but I'm going to have to fix the bowl/ n/seat o-ring now it has been fine for 2500 miles of mostly off/road riding.

 

If you find yourself slightly lean on the main jet you might want to shim up the needle and see- a dyno test would tell you what you would really need to do.

 

Thanks guys, yes a dyno run would tell me what I would need to do in regards to jetting. But what about the mixed up slides does it really matter?

 

If they are not binding and have smooth action I wouldn't sweat it.

 

^^^^ what he said !

 

The slides are the same.
The springs are not.
Just line up the springs and check the height.

Two of the carbs are down draft and two are side draft.
The side draft need a slight stronger spring to counteract gravity.

All the ones I have taken apart the springs are all about the same height.

 

Don, springs differ on some early models, but not on later ones.

For example, gen 2 springs are all the same. If you don't believe it check parts #s.

 

Thanks for that info squirrelman.
I have no reason to doubt you.
All springs the same then.

 

Ok my bike is manufactured in Feb/06, so that makes it a mid year production run. So I will check the springs and see if there are two that are a little longer or slightly thicker gauge wire. But if all Gen 2 are the same I won't worry about it. Just wonder why the service manual is so adiment about not mixing them up.
