I have a few questions here.................
1. Why is the XE breather mod needed and does it help??, i have looked on the archives and it say what you cut away but gen is needed.
2. I will be running the above on twin 45 DCOE carbs so will the carbs "ice" up in winter time like other carbs do without a walm air feed??
3. How tight do you tighten ARP big end bolts??
