BS (CV) Main Jet Size

[Vmass]

I ordered what I hope are the correct main jets (112.5) for my 1983 1100e. These jets are stated as " small" main jets. They also have " large" main jets.

These are the ones I ordered: http://www.ebay.com/itm/361325436539...%3AMEBIDX%3AIT

Are they correct?

Did you check the STICKY at the top about factory carb setting stuff???

And theres this huge chart...

EDIT..the "small" and "large" refer to the diameters of the jet tops. Some bowls wont let the larger diameter jets set into the recess right.

Hi Chuck, Sorry if I didn't phrase my question properly. I did read the chart which states the main jet is #112.5. The Mikuni #112.5 main jet is available in a " small " main jet as well as a " large " main jet. The chart does not specify which one is correct.

I did find a listing on eBay that stated the " small " main jet was the correct one, which is what I ordered.

Just thought I would ask since I will not be opening up the carbs until next weekend and have time to order the others if the smalls are incorrect.

My 83 550e has 2 different size main jets. The 2 center cylinders have 102.5 mains and the outer 2 cylinders have 95 mains. My 550 is a 16 valve TSCC motor with the Siamese carbs. Not sure if the 1100is the same configuration.

Hope this helps,
Don

Thanks Don...I don't know a ting about your carb setup. However, the 4 mains on the BS carbs are the same.

Hes talking about the physical size of the jets here. Minkuni makes a "large" type and a "small" type. My BS34's use large type jets. I had to learn this the hard way when like you, I ordered small type jets off ebay.

Yep, the BS34SS carbs on a GS1100 use the large head main jets. Should have asked before you ordered.

Rich, why don't you order from Suzuki, Parts Outlaw $5.92 each (was that a set of 4 or $12 each?)

David,

Yes, that was for a set of 4. I had already placed an order with my supplier for a bunch of parts, realized I didn't order the mains and thought I would just make a quick transaction on eBay!

I had a 50/50 shot of getting it right. I was told that the performance is the same and the smalls will work just fine. A little research showed that the only difference is the width of the head. The length of both the threads and the head are identical.

With that said, I am not in a rush so I will order the large mains (already ordered) and consider that I now have 4 good reasons to search for another bike!
