A rather special 500 from the Netherlands

Eldert kindly sent me some photos and information about his 496cc Ducati



After receiving this photo I asked for some further info and this is the reply from Eldert:


"Hi
The modifications are really too many to mention them all. The cylinder head is modified to 60 degree combined valve angle,  relocated the rocker arm pivot points and used Pantah rocker arms, then when timing the camshaft we found out the lobe centres where way off so we made new camshafts with V2 profile on them with the lobes pulled further apart."

Stronger gearbox





"The close ratio gearbox we bought kept on breaking gears ( mostly 4th ) so I had new gears made locally in a bigger module and made the gears  wider where possible."



Comparison of 4th gears


"We had new crankshafts made with 78 mm stroke to accept Yamaha big end pins and rods."



78mm stroke crank



"Cylinder liner is a modified Peugeot diesel engine item  ( about the only one with a collar big enough to suit the Ducati )"


Thanks to Eldert for the photos and for sharing so much about the modifications to his engine.
