CB550 F1

[DJ7OOK]

Hi, advise needed, I have recently brought a 1977 CB550 F1 I believe that's a super sport? It's running on pod air filters and a 4-1 Straight through exhaust. I have sent my carbs to Gerben for a good clean and refurb. He has informed me that the carbs are running on a 110 main jet which is not standard. 100 is and has asked me what I want to do? The previous owner had the bike dyno tested and it was running well but the carbs were leaking fuel hence the refurb.
Thanks

Pod filters and straight through? If it was running well on those, have replacements of the same size fitted!

Same on mine pods fitted with 110s works well

Yeah 110 main should be good for pods, needle clip should be middle position too

In Gerben's defence he was not aware that it was a F1 and that I was running pods and straight through exhaust.
Gerben has also discovered that someone one has done some braizing on the drilled holes on the main jet which he says this is not normal ! Why would this have been done ?
