Help please ?
Sent my Le Mans cast iron barrels for a rebore
For fitting 2 nd oversize pistons ( new old stock)
The shop doing the rebore wants to clarify the
Piston clearance spec for 83 mm pistons in iron bores ?
Anyone got the tech spec handy to answer that one
Would be very grateful 
From the factory manual:-
Original is 83mm - 83.018mm,
1st oversize is 83.4mm - 83.418mm,
2nd oversize is 83.6mm - 83.618mm.
If you pm me your email address I’ll send you a scan of the page.
P.S. Just got your email from your profile, page scan on it’s way.Doug McLaren2013-10-15 21:30:47
