Dyno Day for the Beta EVO MK1


Dyno time!

With all the drama's of blown up engines behind us. We finally got the db1 Beta EVO onto the Dyno. A call to Motorcycle Weaponry at Mona Vale got me hooked up with one of my old racing mates, Roger Quinlen. I had raced against Roger back with PCRA in 1997 1998. A quick base line showed we had 72HP at the rear wheel. With the Nemisis onboard we set about dialing in the fueling, it took a while to get a nice smooth AFR, it was worth it with the engine picking up 4 HP for 74.

We tried unsuccessfully to remove the big dip you can see in the power curve at 5800rpm. Adding and removing fuel and advance to the rear cylinder which was showing a rich condition during this range. Nothing would fix it. And we can came to the conclusion that it was suffering from the short header on the rear cylinder which was a pretty standard design for a lot of Ducati engines.

Once we had a clean map we tried some of the Elf fuel I had been advised to try. The results were very impressive! The bike picked up 4 peak HP, and 4 ft/lb of torque. Thats 5% power and 8% torque! WOW! Lovely if you can afford the $11.00 a litre price.

Roger also picked up that the bike's clutch was slipping. Dialing into a zoomed view on the dyno allowed him to show me the spikes and loops caused by the clutch slipping then hooking up. I ordered a new clutch on the way home. Thanks Roger!

Round 3 National BEARS Morgan Park, QLD

The db1 Beta EVO in full flight!
Friday May 7: Practice

A new track beckoned for all but a scant few of the F3 field, Mike Coates was out before we'd turned a wheel with a practice injury. Leaving the title a three way fight between, myself, Glen and Deano. We were also joined by a bunch of very fast F3 locals aboard Supermotards. Friday practice was a bit of a strange one, with timing being provided for each session. Makes a change from NSW, were they bin you for having a lap timer on. The track is a total hoot, its tight, complex, and challenging. Half way through the day I had to replace the battery as the existing one was buggered. The DB-EVo was pinging on several parts of the track where I was getting the throttle open wide at high speed. If it was load or speed related I could not tell for sure. I dialed in 5 percent fuel to counter the detonation. The DB-EVo was also exhibiting the same rear suspension problems I'd had at Wakefield in high load corners. I dialed in another 6mm of preload on the rear spring, this stopped me bottoming out the shock.


Saturday May 8

Saturday was two qualifying sessions, followed by two races. Thankfully they had split the grid into F1/F2, and F3/F4/F5, otherwise the traffic would have been terrible. It was still bad enough, but I made the most of it post a 1:10.7 in Q1 for 5th, and a 1:09.7 for 3rd in Q2. Putting me 3rd on the grid, and best of the guys competing in the BEARS National Challenge. Just behind me was Deano, Glen was struggling a bit further back in the pack.


Race 1: Best lap 1:09.697 F3 2nd
Race one was perfect, I got away well with three Motards and Deano ahead of me. Deano did what I thought he would and race the Motards, this made him run wide on turn four and I slipped by him with ease. For the remainder of the race I chased the motards and set a new PB lap of 1:09.697 to come home fourth. Glen got Deano for fifth, the pair some ten seconds back.

Goose leading Glen


Race 2: Best lap "HA GOOD ONE" F3 9th
Race two was not so perfect. My start was not the best, but I used every ounce of cunning to get back past Glen and Deano before I crossed the line for the first time at pace in fourth. Unfortunately for me, an unnecessary yellow flag on turn three had me shutting the gas for the drive down to turn four. Turn three is a blind fourth gear sweeper so I was extremely slow under a caution, only to find no accident around the corner. In my haste to get away from the chasing pack I arrived to hot at the next bend and lost the front end. Data loggers do not lie, and I'd hit the apex 8km faster than ever before. Thankfully the DB-EVo crashes good, I picked her up, straighten the left bar and take off after the field. I cross the line in 19th! Lap three and I peg back two riders. Lap four according to my mates in the grandstand I overtake 5 people from the final corner to turn three. On the final two laps I muscle my way by two F3 competitors for some valuable points to come home outright 11th or 9th in F3. We throw a new handle bar on the bike and replace the brake pads as a precaution.

Sunday May 9

Sundays dawned foggy and cold. In warm up I post a time four tenths of my best for the weekend and I was more than happy with the machine and me.

Race 3: Best lap 1:09.121 F3 2nd
Race three saw me start from 11th place on the grid due to my fall. Thankfully the guys ahead of me did as I expected, all crowding themselves on the apex of turn one so I could barrel past them all on the outside. 11th to 5th on two corners. Ahead of me Deano had broken clear with the leading three Motards. I spent two laps tracking him down, posting a 1:09.121 in the process. However once on Deano's tail the Triumph became extremely wide. We finished that way, Deano, Goose, Glen.

Race 4: Best lap 1:09.544 F3 2nd
The final race of the weekend had the same conclusion as race three, with me unable to get past Deano. Both of us circulated in mid 1:09's for the first half to the race but spent the second half tripping over each other. Once more both me and Deano scored points back against Glen who finished just behind us.
Dean and Goose at play in races 3 and 4!
