Apologies if it has been answered before :
on flat tappets valve lash was set at 0.10 (4 thou) inlet and 0.15 (6 thou) exhaust. Are these tolerances the same for the roller tappets? I seem to recall 0.15 and 0.20 respectively mentioned somewhere.
Many thanks

0.1 & 0.15 were the original factory clearances for flatties. They recommend 0.15 & 0.20 for flat tappets at some point in an attempt to increase tappet life. Rollers should be 0.1 & 0.15.

Thanks Beetle, that's what I have set my rollers to. Just back from England armed wth Carbtune.
This morning checked valves, synced TB, Guzzidiaged it, loaded Beetle map, went on a 200kms burn up.
That beautiful Tenni beast sang like a canary and went like wind tail of hell. Simply AWESOME.
Thanks for your efforts with the maps.
