Returning to an older "thread" - I made a rough and ready measurement on another three heads, and all have spark plug holes which are considerably deeper than...
Hi Craig, The science of combustion inside an engine was still in its infancy during the 1920's - Ricardo had done some research, but it was Harry Weslake who ...
Hi Paul. Yes, that seems quite plausible. All the heads I have checked are OHV (8s and 9s from late 20s through early 30s) so I would be very interested in...
I have a Model 95 which has a deep hole! One Sunbeam instruction book states a Lodge H 54 is recommended for this model and H1 for all others.What reach is the...
I use an NGK A6 in my model 8. I know that the threaded hole is much deeper than the ½” of the A6, but it’s a modern plug and seems to work OK. NGK also...
Just checked my '25 Longstroke; the end of the plug is flush with the aluminum plug carrier/valve cover, and the plug tip protrudes into the comb. chamber. I'm...
Or a fresh bore. Or maybe the carbon is from over oiling? James Sent from my Verizon Wireless BlackBerry ... From: vintagent1@... Date: Sat, 7 Jun 2008...
Hi Gary - these are all 1/2". If you look back a few posts, Paul posted a page showing specs for Lodge spark plugs and a comparison with some other makes. ......
In my Photos of my 1925 Light Solo posted It shows a muffler which I don't know it it is correct?I say the machine is 1925 because of the S/N. Look at the...
Dear Sunbeam friends, I live in Switzerland and posses a wonderful SUNBEAM - model 90 of the year 1929. The entire bike in in pieces, sandblasted, covered with...
HI Alan I've just picked up my running and largely original B24, as far as I'm aware it's the same bike with a smaller piston, in essence! I'm out near Kempton...
Paul--Thanks for your reply--Looking at your bike would help considerably---my mobile is 07831 281686 We dont have this manual you mention & could do with a...
Hi max. Sorry for not replying earlier. Thats a tough call - I havent seen any illustrated parts list or diagram of the whole machine that can be used as...
Dear Craig, Thanks for your response. What I need are details how the frame is being put together. I have them all in single elements. What is most important...
Hi I am a new member to the sunbeam forum,and have just purchased a 1929, 350cc, sv, model 2 sunbeam, there are a few important bits missing ie the kickstart...
I've just investigated why my 1925 Longstroke was lacking compression - and discovered to my dismay that the piston is damaged because at some stage it has...
I would suggest new rings until you find a new piston - it's a very easy job. I use Hastings piston rings, as you can measure up your bore and the dimensions...

I was looking over my new acquisition 1929 350cc sv model 2 before stipping it down for restoreration. and notice it has only one outlet from the oil tank?...
I have never seen anything resembling a shop manual for the sunbeam, It is likely your 12 is total loss, probably sends oil from the engine to the drive...
Simple equation; no way for the oil to get back into the oil tank (without a ladle) - you've got a total-loss system. Surprising, since Sunbeam went for an...
Yep the oil is pumped to the crank then pumped thru the breather to the chain. James Sent from my Verizon Wireless BlackBerry ... From: vintagent1@... ...
Pitman's book of the Sunbeam is probably the closest thing to a workshop manual - covers bikes from '28 to '38. You can get it in reprint or original without...
