BS or VM

[Guest]

I need to order bigger jets for a 81 gs450e with the BS34SS carb. Im going up one size for the pilot, which would be 120. This is under part number VM on Z1s site. Is this the right pilot jet? The BS part number pilots are size 55 and down. What one should I order?
Thanks.

Well, you have the BS series carbs, not the VM.

Your MAIN jet might be a 120, but not your pilot.

Your stock PILOT FUEL jets are 45.

Why are you feeling that you need larger jets and why only one size?

If you are installing pipes or pods, you will need to go up more than one size on the MAIN jets.

Usually, only if you go into full-gonzo mode do you have to increase the size of the pilot jets, and even then, no more than one size.

120 sounds wrong for a pilot jet size. If you were talking about the main jets, then they interchange between the VM/BS, but not pilots. The pilot jets are totally different between the two series of carbs. Click the link for the proper pilot jets in a BS34: http://www.z1enterprises.com/SearchR...&KeyWords=bs30

120 really sounds like a main jet size to me.

Pilot jets are different from the Main jets. Pilot jets are typically referenced by numbers in the 30's and 40's, Main jets are numbers above 90. Your reference to a 120 Pilot jet is incorrect.

The correct pilot jets for your carbs are labeled as BS30/96 on the Z1 site. The correct main jets are listed as "Mikuni Large Round Main jets" - look in the Kawasaki info for these.

Edit: sorry for the redundant post. The last two posts came in while I was typing.

So I am not the only one then, seems I am in good company.

Ok, thanks.
I wrote it down wrong, will order the 47.5 pilot jets then.
I am installing pods and cutting down my exhaust.
Thanks for clearing that up.

I ve been reading prior posts about the 450 with pods. Some reference the pilot is 17.5 stock, some say 45 pilot. So what one is it. Thanks.
