[Ducati] Removing Crankshaft

[Barry]

Thank you all for your advise. I must admit I am feeling to intimidated and
uncomfortable to split the case, if I was working with some one who had
experience like you guys I could learn and push my limits that much further
next time. But up here in Canada there isn't much around for Duc shops, in
fact the closest one is 300 miles away from where I am, and since they are
the only ones that keep stock, they charge incredibly high, and they are not
willing to lend any advise, and they are so busy they can never help unless
the bike sits at there shop for a month, and there goes my race week ends.


Any ways I have learned enough to do the top end maintenance, like shim
clearances and cam belts, I know I can keep my bike healthy and strong for
the race track. So to make a long story short, I will drop the motor (
gently ) and send the whole case to Guy Martin, along with the heads, from
that point I feel confident getting everything back together.

When I have the motor back together I would like to look at throttle body
synchronization and other little adjustments just to have a good running
race bike. Thanks again all.

Barry
