Tappet clearance check & adjustment
Posted: |July 19th, 2020|, 12:16 pm
Hi All,
I have just stripped down my V Rap for tappet check as its now done 31000kms (don't know previous history), took off everything to allow easy access. Double and triple checked TDC and cams positions for checking and the clearances are way too tight.
Front : IN - 0.05mm, 0.05 EX - 0.09,0.10
Rear : IN - 0.06mm, 0.06 EX - 0.09, 0.09
Way too tight for recommended tolerances.
Is this normal as I've read that intakes rarely need adjusting?, it looks like they may have been checked at 12,000Kms as there are timing marks and new sealant to head gaskets.
Any advice would be gratefully received!
Thanks
