Looking to have my carbs rebuilt

[RogueZuki]

The bike sat for quite awhile before I got it and as far as I know, it need to have the carbs rebuilt/cleaned. I'm mechanically knowledgable enough to take the carbs off the bike, but I'm not comfortable enough to redo my own carbs.

I'm wondering if someone on this forum would like to do my carbs? I'm not looking for a handout but from what Phaseman has told me, he's been quoted $400 for his four carbs. That's a bit much for me. I'll pay for shipping, parts, and your time.

If no one here would like to take me up on this, does anyone have a link to an online place that could do this on the cheap?

Really, you've only got two carbs.
Go for it, it is simple.

It's not a hard job. Just take your time, take photos so you don't forget where everything goes, and ask us questions here if necessary.

If you absolutely can't do the job, drop me a PM and I'll help you out.

I don't know where to get the parts I need to do the job. I'll try the search function, but would really like some advice as to where I can either pick the parts up I need or order them online. If you guys say it's not that hard, then I guess I'll give it a shot.

These o-rings worked on an 86 450 I did http://www.cycleorings.com/
Here's a rebuild tutorial http://www.thegsresources.com/gs_carbrebuild.htm
You only have to do half the work!
Get a gallon of carb dip (Berrymans) and some cans of carb cleaner.

Renobruce might do them for you... I think he's willing to do carb work.

I like to soak them in the Berryman's, rinse with the hose & then spray them with brake Cleaner - No residue. It is not a dificult task, Just take your time. www.cycleorings.com for the O rings. If you are carefull that is all you will need for parts

what about the diaphragms? i hear they can get pin holes in them. how can i find out if mine have those?

[salty_monk]

Hold them up to the light whilst stretching them out a little... You'll see pretty easy if they have any.

i just read through that pictorial, damn that's some scary stuff. i'm now feeling intimidated all over again.

Good work folks! I've been tryin' to talk RogueZukie into doing this himself for weeks... You guys got to him in one night!

You GO RogueZuki!!!

There are a few extra things to understand about doing the carbs if you have not done this kind of work before...

- Make sure you have the proper tools to do the job. You need a tight fitting #2 phillips screwdriver for the screws on the top caps and floatbowls. The larger screws holding the carbs in a gang need a #3 screwdriver - these ones are often very tight. Using an impact driver is recommended on these.

- To remove the pilot jets, and pilot air screws, you need a tight fitting small blade screwdriver. I ground down a larger screwdriver until it fits nice and snug in those small slots.

The carb rebuild often goes array when removing the pilot screws and/or jets - people butcher the slot in the screws if the screws/jets bind in the carb body. Using heat and PB Blaster really helps. Just be very careful to not force anything.

Another place where people mess up is when removing the float pin - they snap off the float bowl post. Supporting the post with a small socket helps keep this from happening. I wish we could get the carb series updated with these added details.

Good luck and hope this helps.

Once you get past the fear, it's really not bad. I just finished my friend's BS30s off his Yamaha Radian. Almost identical to the carb rebuild guide. One step we skipped was removing the pilot jet. It's very small and apparently a real pain to get out. There's no o-ring or anything behind it, so there's no reason it would have to come out before going into the drink.

+1 on well-fitting screwdrivers! A $25 Craftsman impact driver works a treat on the top & bottom screws. Less for the impact, and more that the bits that come with it are fantastic! A 4mm socket did a great job supporting the post, and dremel-ing the head off a finishing nail made a fantastic drift for removing the float pin.

We're using Gunk dip b/c Advance Auto didn't have Berryman's. NOW I find out that AutoZone carries it! We're dipping parts for 48 hours per someone's suggestion here. Not really a hardship b/c we're waiting for parts anyway. He was quite paranoid about dipping the throttle shafts and ruining the seals - though most people seem to get away with it with no problems. We took the handle off the basket and put it in upside-down. The dip was still a bit (5mm or so) deep so we stacked a couple of small combo wrenches under the throttle body. Clean carbs and clean wrenches! A little warm water and an old toothbrush around the throttle return springs and man they come out looking almost new!

I'm going to do mine soon. Was thinking about making a video series about it. Good idea?

A video would be great.

One comment about the pilot jets - they have a very small orifice and often clog. I'd go as far as to say that removing them and holding them up to the light to make sure they are open is one of the most important steps in cleaning the carbs.

Seems one or two of them are always clogged on bikes that have sat too long.
