Brad The Bike Boy: It does indeed go to 11

It does indeed go to 11

I took Minnie down to Dynobike this week after I had some time to fill in due to a no show, which went rather unexpectedly very badly.

It appears Minnie is inhabited by some sort of poltergeist, the kind that enjoys messing with dyno control systems. The inductive pick up, used to read engine speed, was registering (albeit not accurately enough to be useful) that the engine was running while being a metre from the bike. We tried some non rpm runs, but the air/fuel readings were going nuts and occasionally the screens would drop out. And then the dyno decided it was too cold.

We did get a couple of "power vs rear wheel speed" runs, but because Minnie doesn't have the tacho fitted, I really don't know how many rpm she was doing. I did see that Dave had already had a couple of M400 in. One of them, labelled as a 2003 so it may have been an ie, put down 37hp at 11,000 rpm. I had assumed that the claim of max power at 11,000 rpm was rubbish, but it would seem I was wrong. Again.

So, first dyno chart for Minnie as a 400: 41hp. I'm looking forward to getting the tacho fitted so I can watch as I ride. I'm pretty sure that I haven't gone over 7 or so as yet.

As an indicator, this is the 2003 model with rpm.

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.
