1974 250 Desmo Questions

Post by desmo_duke1 »

Hi
Anyone know where pointer should point on clutch cover on my 250 desmo widecase for optimum setting. Has anyone experimented with other settings than standard,and had better results?

Having trouble getting my desmo oiltight.keep loosing oil at head/barrell
oilring joint.Renewing oilseal doesn't work,I only loose a little oil however
when riding the airflow spreads it about alot ,so it looks worse than it is.Any tips on this problem?

I am going to fit an Amal 900 concentric ,as my dellorto is worn out,
has anyone done this,and what are the best jets sizes etc.

Many Thanks
Alan

Hi Alan
the closing rockers on a desmo single need a special rubber plug on
the one side and a small O ring in the rocker shaft on the other side
otherwise i will leak like you discribe because the hole for the closing
rockers is between the head bolts and therefore will weep oil
between the cilinder and cilinderhead
