The engine is now back in the frame, a nice and easy job with the removeable bottom frame rails…

I didn't want to use the frame as a breather as it can rot them out, and rust partials can drop down so I am told...  so I decided to make a new breather the vent the crank case and also the heads.  Here is is...  will it work?  Who knows, we will see!!

Two jobs today...  first was to make a paddock stand.  I hate the universal ones as they are very difficult to get a bike on one on your own..., and often not that secure.  this one positively locks onto the wheel spindle, and when its on the lift I can clamp it to the top so its nice and secure.





The second was to make some bushes out of bronze to take the play put of the clutch lever as the hole had worn oval.  I drilled it out and made some over size top hat bushes.  Finally, here it is on its wheels!

I think using rockers cover breathers is of little use on these bikes. Mine always used to produce mayo and the bike rarely did any low mileage journeys. I removed the rocker breathers and blanked them off. That was years ago and I've not had any problems since. The main crankcase breather is more than man enough.

Interesting. The old Loops did not have rocker cover breathers and I've never found a trace of mayo on either of my Loops.

On the later Tonti engines, the rocker "breather" connection is actually the oil return from the breather box, or frame top tube in some cases.

It used to form in the breather pipes and drip back into the rocker covers, nasty stuff.

interesting comments on the breathers...  I will suck it an see before I go too mad!

I pondered for a long time on the throttle arrangement for this bike… I wanted to keep the pull to open, pull to close for a couple of reasons… First, its safer… manufactures didn’t go to this arrangement for no reason as bikes evolved. Second, it means you can have much lighter return springs, which in turn males the throttle much lighter, particularly if you are going for a quick action. . A light fast action action throttle feels like you have 20 BHP more!  I do find a heavy throttle spoils a bike for me...

I couldn’t find a 4 cable throttle anywhere, so I ended up making one from scratch…

Nice bit of engineering there. I suspect I would have gone the easy route and used splitter boxes.

I did once on a Ducati build...  but I was never happy with the result...  hence the 4 cable throttle...

The centre stand on my ES2 is one of the worst I've ever encountered. I normally use the prop stand (adapted from a Kawasaki ZZ) but knocked this together to attend to chain oiling etc. Not engineering but bodging (in the original sense) and recycling of stuff lying about in the shed.
