MV Agusta 312R dyno chart

I tuned a MV 312R recently, mapping a PCIII over the RG3 ecu. It was fitted with Arrow header and cat eliminator pipes, RG3 mufflers and a BMC air filter. Certainly more power than the previous (all std) F4 1000 I'd dynod. I ran another 312R on this dyno recently, which was the spare bike of the team that raced last year in the Australian Superbike Championship. Between these two runs though the dyno roller surface was reconditioned, so I'm not sure if the comparison is totally accurate - the race 312R may be a bit low. The race bike had a factory head and cams with std bottom end and was also remapped using a PCIII. Red is this 312R, green the race 312R, blue a Tambo with RG3 mufflers and header fitted and yellow an all std F4 1000. The Tambo looks a little flat on the graph, but on the road between 8 and 10 I'm sure it felt faster than any of the others - it was quite intense in that rev range.

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.
