NEW MEMBER Main jet size - 1980 LTD 1000
21 Feb 2026 08:12 - 21 Feb 2026 09:23
I have owned this bike since 1987 but it's been sitting for the past 15 years. Trying to resurrect. I just got the carburetor slides freed up using a heat gun. Now I am trying to figure out what my setup is. I can't seem to read the main and pilot jet sizes very well. Any help would be appreciated.
In order to fully clean the slides/bores should I remove them or just do that in place?

My old eyes see a 15 pilot jet and a 118 main jet.

What my old eyes saw as an 8 could well be a 5.

Thanks all. From what I'm reading this bike came with a #15 pilot and 102.5 main jet so the main jet has been upsized at some point. I really don't know when that was done. The pilot jet seems to be stock at #15. I do recall the bike running really well when it was tuned (use to take to a good local shop) so I will probably stick with these for now.
It does have a 4 into 1 Kerker header and the stock air intake is gone. The only thing I recall when last riding it over the years is some occasional popping.
Thanks again.

Thanks everyone. Looks like the main jet has been upgraded at some point from 102.5 but pilot jet size remains #15 at stock. I am going to stick with that for now since it's been that way a very long time, possibly before I owned it. The bike no longer has the stock air intake and has a vance/hines 4 into 1 header.

If the air box is gone you might want to look into Zed1015's air corrector jets designed for use with pods etc
