Valve clearance.

Subject: Valve adjustment - looser settings

Has anyone gone as far as 0.30mm on intake clearances? Or out to 0.35 or
on exhausts? Would these looser settings (perhaps in combination with
appropriate TPS, BBS, and throttle stop screws settings) tend to improve
low-end grunt and overall smoothness? Are Oilheads at long-term risk from
looser valve settings?


Rob Lentini tried doubling the valve clearance and found it to make the bike 
smoother  and reduce the surge.  Makes sense as opening the clearance 
reduces valve overlap and lift making for milder valve timing.
