What is my carb type
05/08/06 at 02:04:44

I don't know what my carb type is but I need to know it because of the rejetting. Is it a mikuni or what?
So can you figure it out? Here are the pictures of my carb:

Sorry for the dirt and oil...

The other question is that does the Keihin jet fit it. My local Harley dealer has jets only for Keihin carbs. I read here that they probably fit:

I do know that the numbering for Amal jets are not the same as the Mikuni.

and do remember the jet has a washer under it that likes to fall out and go under the starter - put a towel over the starter any time you're doing work on the bike.

also the screws that hold the bowl on are very soft - use a good phillps and a lot of presure to break these lose or they will strip out, and replace them with stainless allen head.

The book I spoke of is the Sudco dealers manual/catalog.

If you are looking for a book to use at home there is the Sudco/Mikuni Tuning Manual...an excellent source for carb theory and practical jetting/tuning information, parts, diagrams...it is "step 1", in the "12 step program".
The book can be found on ebay.

As I did the seat mod yesterday in 1/2 hour. Which book do you recommend to buy _generally_? Clymer? Anyway I ordered the 152.5 main jet. And discussed the choke knob problem too with tha dealer who is a Mikuni specialist.

So you need to know what the ls400 has in there before you plan on doing the swap

20 years now as a programmer and still not need glasses. But my eyes are always burned, sometimes watery.

Yesterday I tried to remove the bottom of the carb but those 4 bolts were so stucked I couldn't unscrew them. I think they weren't moved for the 10 years since my bike was made. That's a pity. Even with an L shaped screwdriver they didn't move.
