FULL RACE Road Legal ES2 NORTON OWNED BY Tom Outwin of New Jersey USA![]() The 88mm stroke crank has been machined oval to clear the piston on B.D.C. using a 6.5" connecting rod. The cylinder barrel is one of my own aluminium cast barrels as these will go up to 90mm bore. I have fitted a B33 flat crown piston as this works very well with the squish band head that I use. | |
![]() The inlet tract has been cut off to allow me to bore out to 34mm before fitting a new 15 degree downdraught manifold for a MK2 Amal concentric. The head is fitted with a large inlet valve and fully gass flowed. I have fitted a set of my superlight rockers at 160g each and a pair of race cams. The ignition is by a self generating fully electronic BT-H magneto. | |
FULL RACE ES2 NORTON OWNED BY Gaatze Riemersma![]() This is his first racing Norton that is in fact an almost standard 1951 ES2 iron engine in a BSA frame. Allthough the engine is practically standard Gaatze finished every race and never came in last. Realizing that he needed a faster and better handling bike a Featherbed frame and another ES2 engine was sourced. | |
![]() Can you believe that this is an almost standard ES2 engine that was raced all season without breaking. This is around the time that Gaatze contacted me for help on tuning his nex ES2 engine. | |
![]() This is the new race bike built using a mid 50's Featherbed frame and the new engine. This engine is fitted with a high compression piston, my race cams and a special cylinder head. This time the cylinder head is an Alfin from a 500T trials Norton. The inlet tract is now 34mm and fully gass flowed right up to the very large inlet valve. | |
![]() Once the new bike had been set up on the dyno it was only a matter of time before the trophies came along. | |
FULL RACE 500 CCM OWNED BY Denis Rawcliffe. Rider is Gary Parker from Preston Lanc,s![]() Please remember that I am a Motorcycle Engine Specialist and work on All Makes Of Motorcycles! I have just fully re-built the CCM engine after it suffered from a collapsed lay shaft bearing that almost scrapped the engine case. The only way to save the case was to machine out all the damaged area and fit a bronze bush that would hold a new needle roller bearing for the lay shaft. Once this work was completed it was important to check the end float on both the main and lay shaft to ensure it would not happen again. | |

![]() The winning machine was a long stroke CCM of 610cc and just had the edge over the 500. | |
FULL RACE ES2 NORTON OWNED BY Peter Ashley of SURREY![]() It is fitted with a steel 86mm stroke crank, ally barrel with 86mm Ducati flat crown piston and the cylinder head has been heavily modified with an oval squish band combustion chamber. With all this work done the engine would still not rev over 6000rpm and at this point Peter contacted me. I fitted one of my 34mm downdraught inlet tracts to the cylinder head and supplied Peter with all the settings for a MK2 Amal Concentric. With the engine back together there was a power increase of 8 bhp at the back wheel but it was still reluctant to go over 6000 rpm. Peter then fitted a set of my cams and this is what he had to say. With the new cams fitted the bike has been transformed! 80 MPH cruising... 100 MPH at less than 7000 RPM. Good traction from 3000 RPM. No noticeable downside, ticks over nicely. Very enjoyable to ride! And will mug Modern bikes on the bypass! If you want to see more try Peters web site at www.NortonES2.co.uk | |
