Nova Racing clutch OK, I admit defeat...new plates, heavy spring, & the standard Moto Parilla clutch still slips, is hard to disengage & drags. Lets face it it was designed for an engine producing less than 5 HP & Parillas idea of an upgrade was to increase plate diameter by 5mm & stick an extra plate or two in there for good measure. If you have a 175 or 250 engine with some performance upgrades - X1 cam, HC piston & better breathing - its going to be a pain with a standard clutch.
We've been rebuilding RMs old race bike & putting
together another race engine or two & have managed to get Nova engineering
here in the UK to produce what is basically a Nova Ducati racing clutch to fit
onto a Parilla Hicam gearbox mainshaft. The unit consists of a new primary drive - crank gear, alloy clutch drum & steel gear, alloy clutch centre & bearing, fixing nut & washers. You need to provide a set of Ducati single clutch plates, pressure plate & adjuster, springs , cups & tensioning screws plus make a new clutch pushrod from 5mm silver steel. This clutch unit is fitted to 450 racing Ducati singles & has proven to be up to the job for several seasons.
