1340 V Twin build

Wed Oct 24, 2012 4:04 pm

Renamed the thread. Seems to be some interest in this exercise in possible insanity so I'll keep adding pics if that's ok with the Powers That Be?

Here's a link to his FB page that shows some more of his engineering expertise.

He said that if he'd had 3 1340 cylinders he would have built a W-3 instead of a V-twin 8)

Kinda glad no one answered this..as I've just seen the cylinders in question & they are 1340, not 2800...

So.. does anyone know the max piston/bore clearance for a 1340?

Check the ovehaul manual, 'My boss told me' won't carry a lot of water if something goes sideways and you have the pleasure of a 'discussion' about your procedures with the guys in the blue blazers, much beter if you can hold up the pertinant page and say 'I did it per this manual reference'.

Don't have a manual handy.. & in this case the FAA won't be involved in any way. There are only 2 cylinders in question & the guy is building a V-Twin motorcycle engine with them... He's machining his own rods, crank, cams etc.
He's pretty handy, he built a bike with a Viper engine in it a couple of years back (Dodge, not Armstrong-Siddeley)

Cool! Rumor has it that a mechanic @ Precision Airmotive on KPAE built a bike engine using two R-985 jugs a few years ago, never saw it but the story persists.
His project actually looks more real world practical than the four wheeled monstrosity that DODGE built a few years ago, something that would make a guy riding a BOSS HOSS pull in for a coke even if it does sound like a UPS delivery truck :lol: :lol: :lol: :lol:

Zane,

Looks like piston to cylinder clearance for the Wasp H-1 is .020-.024 "loose fit" with a replace or next oversize at .030. For the Hornet E, it is .018-.022 "loose fit" with replace or next oversize at .028, e-mail me I will scan the page from the overhaul manual for you.
