JANUARY 2013 MT WELLINGTON

I spent my Saturday and Sunday at Mt Wellington for a practice round and a non points race day. Having not raced since November, I was eager to get as much track time as I could handle which consequently ended in my body now being wrecked!

It was a really good weekend of bikes with clear skies and a breeze to keep us slightly cooled. I let a few of my mates have a go on my FXR which should hopefully kick them into gear and mean they’ll soon be out there. During the Saturday practice I made the most of my opportunities to follow Brian and others where I could in the hopes their riding ability may rub off on myself. Brian gave me a few pointers on braking which helped hugely and lead to setting a new PB of 32.61s anticlockwise. On Sunday I improved on this with a 32.20s anticlockwise and I’m eager to keep the ball rolling into the 31s bracket! Thanks guys, I appreciate the hell out of any guidance I can get.

Races run:
5 lap sprint anticlockwise with no grid order (first on the grid gets pole) then straight after returning to the pits, back out for a 5 lap clockwise sprint
10 lap race around ‘the ring’ (midfield coned off) anticlockwise then straight after, clockwise 10 laps. Again no grid placing.
Borrowed bike race – anyone can enter as long as it’s not your bike – 10 laps clockwise then 10 laps anticlockwise around the ring.

I swapped bikes with Rick’s son Will who rides a CBR150 with cams, exhaust, carb, which was really fun! It had much better throttle response and seemed as fast as my FXR (which has more work done to it) although I need to work on the jetting of my bike still. The CBR150 hasn’t been on the dyno before but I’d love to over lap the curves between bikes for a comparison.

Thanks to all that helped out and organised the day, great fun!

SPANIARD DYNO

October 8, 2012



Note: old man in green is my old man. The guy sitting on the bike with a broken arm and doing the honours is Kelly (racing related injury) who I bought the bike from and who built up the engine.

I got the bike on the dyno on Saturday and ran her up to tune the new carb and exhaust in. The last time it was on the dyno it had a hideously loud but well functioning megaphone exhaust which has been swaped off for something a bit quieter to keep the peace. Whilst it was making almost as much power as it was with the megaphone (19.6 vs 20.4hp), the curve was on the piss. A few changes in pilot and main jets and resetting of the fuel floats filled in a large hole in the curve.

Unfortunately I didn’t have a new plug with me because it seemed that the current one was a bit poked. A tighten up of the gap found a bit more in the curve but we left a little disappointed in the result. Although it went off the dyno a huge amount better than it did when it rolled on, the illusive megaphone curve taunted me whilst trying to get to bed that night. I’ll get a new plug and consider having a go at moving the needle around but I’m really dreaming of how to quieten down the megaphone to an acceptable race level.

I painted the seat frame on Sunday which improved it’s looks drastically but with summer holidays coming closer and my wallet tightening further I don’t think I’ll paint it until next year… maybe. Racing is on this weekend and hopefully the rain stays away because I am beyond addicted and I need a hit of racing.
