I'll play around with gearing. I found a 19 tooth sprocket I knew I had but couldn't find. I also have an 18 on hand. I'll play around with those.
I think I'm pushing the DOS circuit pipe as far as it can go. I have an estoril on 3 other bikes. I dont want to put ANOTHER estoril on this bike. I want some variety! The estoril would be a sure bet on more RPM.
The PHBG killed the 15mm Bing on midrange power on another bike. I wouldn't mind putting the PHBG on this bike to improve midrange. But this bike is pretty original and nice so I would love to keep the sidecovers if possible. And Bings are soooooo reliable and simple.
