Have just been on a few test runs around the block. Not a massive wheel spinning increase in power, but i can get from stopped to slow a bit quicker. I would say the torque down low has increased the most i.e, if i drop the clutch it doesnt just bog down and then putter away, it gets up and goes rig...

just got my milled head back. Had it milled by 0.060" giving a combustion chamber of 27cc. So my maths seemed to have worked out pretty well. Gave the engine a decoke while i was in there, doesnt look too bad. Valves all seem to seal up happily, i see i have 1mm printed on top of the pistons, s...

pcd is 4x114.3 which is very common. The only issue is the centre hole will be too small for the mm hubs. i had a set of rear drums trimmed down (4 prongs that centre the wheel) to fit a pair of early 4 stud ford falcon wheels I never got around to getting another set of front drums to trim down, bu...

ok, some further measuring gives an averaged combustion chamber measurement of
51.8mm
61.8mm
10mm

meaning in order to achieve about 7.5:1 (32cc to 27cc) i would need a 1.5mm or abour 0.06" skim

ok gents, have just cc'd my spare cylinder head *keep in mind i have no history of this head, but it has no markings to indicate its been shaved in the past. So lets assume its std. im getting 32cc per combustion chamber (using champion L86C plug) Now due to the shape of the sidevalve combustion cha...

Just trying to figure out how much to skim to get to the 7.5 ratio. Was hoping you may remember how much was off your head to save some maths, but will CC the head today and go from there. Yes, i do have a temp gauge fitted. http://i136.photobucket.com/albums/q194/tortrontortron/P1070173.jpg The pan...

your bolt is also around the opposite way :wink: perhaps flipping it around would help (i think that side of the casting is thinner) 70mph sounds pretty good for a sidevalve! I would imagine the electronic ign really comes into play on start up and at higher rpm. Must beat the old Lucas T.A.C kit. H...

are you missing the bolt? its a piece of round steel, with an arc cut out of it (to match the distributor hole in the head) when you tighten it, it rotates and locks the shaft in place. Or do you want the other type. have been looking at those kits, let us know how it gets on. Also is your distribut...

Have taken the old girl for its first drive in 5 years last weekend. just on a rebuilt original carb and exhaust manifold. results with larger rear exhaust, free flow muffler and lightened flywheel are promising. Revs very freely, its been a while but if feels to be getting up to 30mph/end of 3rd ge...

My original twin carb set up was for two 1 1/8 carbs (looks better imo too with all the brass bits). I think twin HS2 will be on the heavy side for the sidevalve, a single one with extractors is probably ideal. Some old data sheets i came across claim a 20% increase in power in the 100e when fitted ...

Hi guys, Havnt posted in quite a while, moved house a few times and lost interest, so my 51 has been in storage for the last 3 years. Am getting stuck back into it and am near having it on the road again. Before i put it in storage i had made up some basic twin carb manifolds, unfortunately someone ...

the engine side of the carb body is about a half inch longer
I also have a water pump to fit and will be using a morey's power booster

a pair of "long" H1's

Iv made up some twin carb manifolds and am currently making a new exhaust.
I have been thinking about skimming the head, tho i am also considering supercharging

Cheers for the ford info, i knew it was a scaled down mirror of something

How far can i safely and reliably bore out a sidevalve engine?

Im looking at increasing the bore to gain a bit more power.

not original (or finished)

10 points if you can tell me what this is and where it goes (i just made it by hand because i put the original in a safe place, so i know damright what it is :lol: ) http://i136.photobucket.com/albums/q194/tortrontortron/whatisit.jpg Have just gotten back into the morrie. If you look a few pics up a...

i see you are NZ
got to BOC - thats where we get ours

go to your local industrial welding supply place (or even a fish market) and get a bin of dry Ice. Wearing thick welding gloves put a handful of ice in a bag (cloth is good) hold the ice against the undercoating for about 20 seconds. This will make it very brittle and it will come off very easily wi...
