George,

Try to keep in flow, time is ticking for the new season.

Here a pic of the oil spraying jet in my DOHC camcover.

You mean the guy who rides this beast can "back it in", (or does he need it for wheelie control Rob)? ;)

Little by little the exhaust is getting its (rough) shape.

Looks awesome Rob!

Despite the low temps wanted to go ahead with the exhaust to see if I could make it complete today.
Next step is to weld the seams shut and give it a heat resistant spray.
Happy with the outcome, easy acces to oil drainbolt and filter.
Even the ground clearance seems ok, although one can never have enough of that.....

Sweeeeet! If that exhaust works good we could try to make it profitable to do a production run..

Hell,  my second language is smashmouth southern.  And some English. So keep us posted and don't get discouraged,  we just a real hard sell sometimes......Bill

Great thanks Rob. My daughter is 17 this weekend and my boy is almost 20 and studying engineering at Cambridge University.

I've not had much time to ride any bikes recently though!

Goerge and 01Thomas,

Pictures have gone due to new payment rules by Photobucket. One have to pay now to show ones own pictures!!!
There are thankfully other options available.

Hey BJ,

All is fine. All mechanical preps are done, now in process of rebuilding the engine with new HD chains, both primary and cam.
