350 trivia
« on: February 08, 2017, 10:59:45 AM »
Here's an interesting slip of paper I just found in a small BS labeled plastic bag. 

I believe it was included in the tool bag when I purchased my new 350 in 1968.

Looks like the bag originally held two #130 jets and this note.
I don't remember well enough to be sure though, that was a few years ago!!

              Great find BS, nothing wrong with your memory, look after that scrap of paper.  This maybe explains why the 130s never got to the UK.     80 degs F was never heard of back in the 1960s !!!!!!  70-75 was a hot summers day !!  :(
   We get 80+ now  :D but I think the temperature reference was Rockford's covering their backsides in case of overheating problems.

   This was shown in a Rockford Service letter, BSG-0062, dated 10-1-67, which stated the 140s were for break-in only and a set of substitute 130s were packed with the tool kit after Ser No. 16T1646. No mention of 80 deg F !!  It also says with the 130s , the float level was 15/16'' and the needle jet clip should be in the second from bottom position. Where did all those 130 jets go ?

I wonder what happened to all of those 130s also.  Of the 13 350s to come into my possession in recent years exactly four have had the 130s installed.

Of the 6 sets in my possession, 5 have 130's and 1 (from Colorado) has 120's....

Another thought, what about factory fitted idle jets? My bike had #30s in it and when I order NOS jets from RC #30s arrived yet the manual states 22.5, any thoughts guys, esp those with multiple bikes ;)

Hi Ryan, I checked a couple sets today and both had 30's vs. the 22.5's in them. So now, like you, I too am curious as to .... what's up?  ;D

There wa a post a while ago about it, stating they run better with 22.5s, but I'm yet to find a supplier for the odd thread sized jet (0.75 pitch vs 0.7)

Ok, I decided to go ahead and check all 6 sets I have and all 6 have the 30's in them.

The manual says 22.5 is the standard. So that means either....

1 - 6 different previous owners changed them to 30's. (for whatever reason)
or
2 - The 22.5 is a misprint in the manual.
or
3 - 22.5 is correct in the manual, but maybe there was a service letter recommending they be changed to 30's. (again, for whatever reason)

Of the eight or so used carbs I have had about 2/3's were #130's. I believe the NOS set had #140's. Hardy, take a look at Sudco #004-005 for pilot jets that fit. Double check my notes, but you should find a range of pilot sizes there.
