Last Track Night I was testing a standard variator vs Malossi variator. Shel's had the Malossi with 4g weights & mine was an old oem one with 4g's.
The test had a result that is now void because I mistook Shel's weights. She was faster than me on the straight, but I later found that she had 5.6g weights in hers.
Next time out we'll both be on our usual 4g's & both with Maslossi variator. I left those heavy weights in hers from the Scooteroo Drag Racing Night some months back that we didn't get to race in because of we were knackered from some business in the city. I'll do that variator test some other time. It's looking quite possible that the bike is faster with Malossi variator.
The Bucket Racer guys commented on how fast we were, but compared to Jason: I was feeling slow....hopefully can keep sight of Jason for more than a few seconds next time out ! 
We also tested 92Ron, with no apparent difference over our usual 95Ron. However, I did notice the "howl" was missing that we get when backing off the throttle at the end of the straight. The howl happens only when the motor has had several laps already. I tried the 92Ron because I figured the recommended 95 for Maslossi Sport cylinders was no longer applicable because we'd effectively reduced compression from the porting, & also I was bothered by how dirty the top of Shel's piston was. I'd changed the piston because of a broken ring tip had embedded itself across two ring seats. Noticed how more easily the bikes started with the 92.....however I'll be using 95 again, especially now that it's warmer nights.
At the next Track Night on Saturday Sept 27th I'll be testing out a Maslossi belt I've had for sometime. I went through a phase of shredding belts a while back when the bikes were road bikes, & because of that I had them sitting around waiting for belts to arrive, & so I swore never to be kept waiting for stuff like that again: hence my stash of assorted belts. I've been using Dayco 7167/1K belt for ages now.....it's been lasting good. The recommended Dayco size for the Bandit 7167K although I swear this is shorter than the oem Bando 747-16-28. I was lucky to source that 7167/1K (thanks to the Dayco AU Honcho), as it sits all the way up the contra pulley, using the whole of the gear.
The Malossi seems a bit short, but after hearing of JTypoon's joy with his kevlar belt, & seeing him lap me last Track Night, I had to Up The Anti, & fit that Malossi....gotta give it a try! I figure I may lose a bit of launch with it sitting so low in the contra pulley, but that shouldn't matter too much because we sucessfully used our adjustable clutches with correct-size bells last time out. It was hearing the bike scream away. I'd still like a bit more bite from the clutch which is at its softest setting.
Jason's bike weighs about 60 something Kg's & my Bandit is prolly a ted under 80Kg. I've been trying to shed weight from the bike as well as myself ! 
Over the last few days I've lowered the bars, dumped the lights & some other electricals. I've also had a look at anything that could be dragging the bike.....no more speedo. There's a few other things I've got in mind....maybe next winter's work. I'd still like the bars a bit more forward than they are.....the front-end needs to be utilised.
Had a look at Lakeside Raceway on Sunday. There were a few cars testing. Don't know what sort of race category they'd be in, but they were Late model Holdens with all their glass.....very punchy motors.
In the pic, on the far side of the track is the part which is used by Mini Motards & Pocket Bikes. It's got quite a climb, & although nowhere near as good as Willowbank, it could be an alternative if we end up losing Willowbank due to their re-surfacing. The pic is from my phone cam.
Think it's about 600metres. On the day I was there, there was supposed to be Mini Motards, but they weren't there, & I was too early for the Pocket Racers. Looks like it may have potential.
The Minin Motards are up to 160cc. There are noise restrictions of 85Db measured at the track.
