Ace 50 oil cooler

Fitted on the bike , can put my hand behind and feel heat flow whilst riding ,front of fins cool rear hot only one side made so far ,big valvehead is different to original head castings as it needs massaging to fit properly . I will leave it on and ride it until i make the other side . I will also drill the top plate now that i have it on an can plan a neat pattern of holes

Would be nice to see a photo shoot of your bike. We need to do another Adelaide group ride too

Hi peter , have you seen the airborne photos that the Dlra doctor has put on the forum . Our salt lake is looking pretty good . I will be some of the advanced party making it all possible , arrive wednesday before speedweek .
 
A little off topic, for which I apologise.

If any of you Acers from Adelaide happen to be trundling through Delamere, say "Hi" to my good friend Si Thomas who farms on Dog Trap Road.

Bought a 1963 Tiger Cub off him (not sure why...) before he scarpered to Australia 22 years ago. Stayed with him once there and saw him over here late 2015.

Tell him he needs a bike!

Regards.

Rich.
 
He is in the sticks a bit but if I go out that way I will try. I spend a lot of time in goolwa . 30 or so km away from delamere

OK .This the latest , 4 × 8mm bosses under the crankcase so mounted aluminium and the bolts go 17mm into tne boss . Riding it and the aluminium gets as hot as the engine ,now the plan was to mount a generous heatsink . Looking for a heatsink and on a garage shelf is a Scott Bonner 45 lawnmower engine with an aluminium head . I didnt need the plug for anything so i left it in .

Hahahaaaaa.. the first boxer twin Ace in the world. Snap an old spark plug lead on the plug & really watch the confused expressions :D
 
^^^^^^^or when you go to speedweek, tell them you're there to set a new speed record for a vertical boxer twin, bet no-one's set one of those yet
 
Finished making a set of cooling fins . Cooler weather is upon us so no 37deg days till next summer , they get hot whilst stopped in traffic and cool once mobile so hopefully some help next summer . Also i have added oo racing tappet covers , they are hollow internally about 20mm , the rear wont achieve much but the front may as the cam lobe will throw oil up into this area .
