Top tip for making it easier to locate seat unit holes. Take three bolts, cut off the heads, and taper them to a point. Thread them into the seat base, position the seat in its final position on top. Lightly press down the seat to leave marks for holes on the underside of the seat. I use this process to mark aluminium brackets in a "blind" situation. You could also just cut the heads off without making a taper and put a dab of paint on them to transfer to the fibreglass if you were afraid of cracking it using aforementioned method
@@obsession_engineering Love this bike you built, I just got one and building it now... about the marking blind parts as the gentleman Jimmy Cav expressed, I have done that with brand new fairings(OEM) and installed frame sliders with a clean 1mm clearance all the way around.. Good Job on your videos and i hope your racing is going good as well. Im 54 now and have too many bikes, too much gear etc.... and my race license in hand. I have a KTM 390 that wont pass tech because I used BST Carbon wheels, then the F3 800 had too much modifications for the class to be accepted, then I tried the new Supersport class, cant run BST wheels either. Now this RS 660 Star/Stripes,, almost done with it, had it since 2-17-23 and i just need to install the ohlins ttx30mm cartridges, Ohlins rear shock, Lightech R Series RearSets, IMA triple clamps, AF1 Race ECU. Austin Racing exhaust is on it already. I rode it 12 miles so far, i have scheduled to run it on track for the March 20th, 2023. Anything that sticks out in your mind that you didnt anticipate before your build?
Aprilia looking absolutely fantastic! Looks fast, standing still 🚀! Excellent suspension explanation as usual Mr. Bitubo! Looking forward to seeing it ridden around in anger & fettling! Well done Dave!💯✅
Great video, informative and interesting. I'm sure most people wouldn't appreciate the time and endless jobs needed to create a sorted race bike, there's always one more task to meet completion. Bike looks ace.
Why do you use Bitubo and not Maxton Dave? And did you consider modifying the air-box and using the underside of the fuel tank as the top of the air box for greater capacity air-box? It's a mod Aprilia guys use on the v-twins. Great channel btw 👍 Love the engineering and the racing.
I'm a bitubo technical centre and I rate the product higher than all the previous options I've run, and that includes the yellow stuff, the red and black English stuff and the purple! We did consider looking at the airbox, but being as it's a pressurised airbox as standard we haven't yet gone down that route as it'd be easy to put a lot of hours in to make it worse
@@obsession_engineering changing the routing gonna expose the sensor wiring to damage in a crash event. Why be scared of just filing 2mm off from that hole?
It is damn tight but I was able to feed the sensor through on my 2021. It takes a little patience but it does fit through if you angle it just right. No dremel mods necessary.

I'd not thought of that, great idea. Thanks

Probably my favourite vid of yours. So informative and professional. Can’t wait for more.
Thanks for the positive vibs 😁
Love this Dave, especially the dog biscuits :) Good to meet you at Bedford last week too ((GSXR 750).

A good project is never finished 😁
Looks awesome Dave. Can't wait to see it going around the TT circuit.
Hopefully I'll be there watching it again this year
Bike looks to be coming on great and nice to see your own take on a RS660 race bike.
Loving this series. Can’t wait to see how it goes at the test. Can’t help thinking they’ll have a similar cult following as the RS250 did/does
They are cool little bikes, if only they smelt like a 250
Shallow I know but can't wait to see it painted!
Me too 🤣
Can't wait to see you at the TT Dave😁
Stunning, can't wait to see it go at the TT
Looking great Dave. Can't wait to see her on track. ✊🏽💨💨
Nice work beaut little bike
Loving the bike Dave, good luck with testing
Can't wait for the TT 🙂
Well done Dave looking good 👍🏻
THANK YOU KEEP UP THE GOOD WORK ! 🏍🏍🏍🏍🏍🏍🏍🏍🏍🏍

@@obsession_engineering I see. That's fair enough. And interesting you say this.
Thank-you for the reply. Keep up the great work 👍
you can just dremmel out the speed sensor hole in the fork leg. I dit at first more than one year ago when i've started racing the RS
I could but it seemed a bit unnecessary, changing the routing saves having to remove metal from the fork
Do you need the speed sensor at all?

Jacob is right. One elusive angle allows the sensor to exit
What brake line measurements did you end up with? I'm grabbing some coremoto lines and doing the same setup but I'm unsure what length I should use
Where did you buy those fairings? It's cool.
Faraldo racing on the Isle of man did the fairing, and I think he now does that seat unit too
Measured with dog biscuits? Well then, I expect that you'll win-a-lot on her at the TT.........yeah, I'll get me coat. 😅
Where you get this lightweight reardisc from? Which brand is ist?
It's from a 125 race team, we found them on ebay!
The shock in backwards???
Where did you get the rear brake disc?
Projection Racing (via eBay)
Do you know what grade of alloy was used Dave?
For which part? If you're talking brake disc, it's steel, just thinner than stock
Thanks. People should not while working
I’ve been trying to wipe off that annoying piece of dust near top centre of the screen for 3 weeks.
