A Ducati 851/853 dyno chart

I dynod an 853 kitted 748 a few weeks ago and thought I'd compare it to my old 851 just to have a look and then figured I'd put it up to show you all. It's the first 853 Strada I've dynod, with the conversion done by the owner. It's running 108/108 cam timing, 45mm slip ons and Doug Lofgren's UM097DL eprom, apart from that it's std. My 851 runs the same cam timing, open airbox lid, ST4 headers and slip ons and remapped eprom to suit. Compared to the 748 it has 1mm smaller valves and is longer stroke and smaller bore (2.5 and 2mm respectively). I also put the 853R I did late last year on for a bit more of a "this is what you can get from an 850cc 4v" sort of thing, although this run was an early one so it's a bit rough fuelling wise in places. red is 851, green is 853 and blue is 853R. As a comparison the 848's seem to be dynoing in the 115 - 120hp range, which would have seen them outpowering most 851 race bikes of 20 years ago I'd think.

The 851

The 400SS

I bought this 400SS (genuine 93 model Australian delivery! Woo hoo huh.) after seeing it in Ebay for what was possibly an good price. As ever, good was too good to be true. Badly repaired and rusted out fuel tank, badly repainted side panels, lots of km (83,000 of the bastards), etc. You know, the usual. Purchased in October 2012, as of now (Jan 2014) I've nearly finished a major service. The cam timing is done with some of the Madasl adjustable pullies that have been drilled in 4 different settings for easy dyno testing. And I have some 900 headers to try a 40mm dual exhaust set up on it (ala M400). Not a great deal of progress for 15 months, so it's taking on a long term feel. There's an F1 endurance style seat base (more taper at the rear) and front fairing sitting around, which will require frame mods to fit. It's a bit of a mental sticking point as this time. But hey, it's not like I can devalue it much more.

The Mighty KR1S 250

How it looked the rainy night someone came to take it away. Painted all black when I bought it, at some point later I realised i could rub the black off and have much of the original colour scheme underneath. Although the main fairing was originally from a red KR1 I think, and definitely badly repaired more than once, so it stayed black. And the tail panel shown was bought to replace the one I smashed the only time I crashed it and the last time I rode it at a Sandown track day. A sensational little bike, holed pistons and frequently failing stator windings aside. The first bike I rode on a race track and the first bike I had my knee down on. And a great commuter too I found. It's sometimes nice to have a bike that won't wheelie past the city speed limit in first gear.
