Bonneville America Forums Forums Technical Forums Performance Mods hsr 42's (long term update)

i got it dynoed today, 62.** at the wheel. i need to drop the main from 142 to 140 and i am all set. the bike runs better now with these carbs than it ever did with the stockers, peak hp i did not pick any up, but the whole band feels beter than ever and with i do the 904 and the heads i will be able to really utalize these carbs. my sheet will be posted with about 10 others (from the NH rally) within a few days
