I'd go with a 125 main jet and maybe a shim under the stock needle or a TBS (Thunderbird sport) needle. I ran that setup with TORs and it worked well.



I'm using 125s with a similar set up. I added the Hyde bellmouth and haven't made any jet changes. The bike is running great. I do plan to have a new dyno run done next time it's in the shop. If it needs to go up I'll try 128s. Can't see going any higher. Dyno performance has been great before adding the Hyde.
