Can anyone recommend a decent place with a dyno for my V4S? I’m convinced it’s down on power so would like to get a couple of runs and see if I’m right! Happy to travel a bit but ideally not hours away.
SPR at Ruddington are good Joe. Sam has been at it for years Parkitt Racing nr Tuxford to are very good.
I get out dragged by a lot of bikes that on paper I should be faster than in my opinion. Thanks Nelly, will give SPR a shout once the bike lands back. On a side note while I’ve got your attention….where is the speed sensor on my bike? I’ve got +2 on the rear but my speedo is way out compared to my gps. Tyre sizes are slightly different but I have run the tyre calibration so hoped this would also adjust the gearing?!
Where abouts? Slow corner exits? Full throttle? Electronics. I had this and I turned down wheelie control and traction control. Once on the boil nothing should out drag you...
Basically everywhere, on the power a fraction earlier than a mate on a 2017 gsxr and lose a few bike lengths. Donny pit straight I lost about 8 lengths to a new S1000RR, probably 10 lengths to a new CBR1000RR down Portimao straight. TC and wheelie set on 2 / 3 depending on track etc. The only think I can think other than down on power is using TD slicks I can’t get good drive compared to a softer slick but the way some bikes leave me is pretty frustrating!
It was Donington pit straight where I noticed I was getting gapped. But only on the exit from thingy- that last off camber corner. I’d follow a reasonably quick rider round there and no matter how daft I got with the gas, I’d get gapped initially. I’d catch them again before Redgate, but initial thrust out of slow corners was crap. I’m not sure if it’s just me but 4th gear, on the boil, feels mental. As if gears 1, 2 and 3 are electronically stymied. Also, how heavy are you? If you’re a 16 stone bruiser and chummy bollox on his new blade is a 10 stone skinny poo, that’ll make a difference.
I’m fairly certain the speed sensors read at the wheel so gearing shouldn’t matter. That said, speed readings on Ducati are way high. I use my speedo as a reference as opposed to gauge. Going into Craners for example I’m reading ~130mph. Pretty fekin sure I’m not doing that though….
I’m far from skinny but my mate on the gsxr is heavier than me! When I was slower I always just assumed it was technique but I’m at a decent pace but seem to lose out on the straights.
3 hurdles to get over; ignore everyone else, live with being slower (for now) and concentrate on your own technique. In the real world, no matter how good you are, there will always be someone better who is more often than not, on a flaming 600. Just my thoughts mind Andy
You might have a point with tyre choice. I was at Donington one day last summer and just for shits and giggles I bought a soft Dunlop Moto2 rear slick. It didn’t last long but the way I was firing out of Coppice was mint! I could physically feel the difference with much better drive. I guess a dyno will give you peace of mind. The operator should have a good idea if it’s a healthy output. And if so look at the witchcraft that is electronic control…
Thought you had a street fighter in the early comment. Apologies. In which case it’s fucked, I’ll give you 5k for it lol
Speed sensor is on the rear wheel. Tyre learning doesn’t recalibrate the speedo as such. Tyre changes or gearing changes alters the wheel speed vs. the engine rpm. These values are used by the chassis electronics. One instance is rev matching on the down shift using DQS.
