Welcome to the forum! Yes, sadly it's pretty quiet around here but still better than FaceBook:)
1) Quickshift: Yes! It is easy and I HIGHLY recommend it. It is NOT the buttery upshift of an electronically controlled ride-by-wire, and it will no 'blip' or downshift for the same reason. It is meant to power up-shift near redline. Ya it should help 1/4 mile times slightly, no one is using a clutch for that anyway.
You can DIY a DynoJet #103 linear sensor (IIRC) as the OE ECM is up to the task by simply enabling the function with ECMDroid, ECMSpy, TunerPro etc. Also plenty of types of bolt on kits available, check out Rev-Mo.com
2) No it is absolutely NOT 'harder on gears' .Your transmission is called a constant mesh transmission. Might be a fun thing for you to geek out on You Tube about.
3) You'll need both pulleys and a belt, not worth the expense IMO, a chain conversion would get you any ratio you wish. Probably cost less too.
4)Yes changing final drive ratios will change the speedo as the sensor is on the transmission output, not the rear wheel. You can either CR dash/calibrate/ or switch the guage pack to a GPS based aftermarket one.
5) I'm all for DIY, But theres lots of CF goodies to be had out there already. I LOVE the CR done by Speed-of-color. https://tekarbon.com/collections/buell/model_ebr https://www.motocomposites.com/categ.../1125r-cr.html https://speed-of-color.de/buell-parts-xb https://mdicarbonfiber.com/collections/buell/1125 https://www.bestemusa.com/XB12_c_44.html https://www.twinmotorcycles.nl/websh...p?mc=1&cid=288 https://bottpower.com/buell-custom/buell-parts/
lots of less quality things on e-bay as well, YMMV
6) IMO for street riding in those temps, stick with the 20w-50 API "V-Twin specific" oil in any brand or synth you want. I would do track days on my CR in 43C days in Florida and use 60W for that extreme example, but thats pretty extreme. The valve train is always gonna rattle like that.
7) Ohlins will have a recipe for that already, just call and order. Wilburs does too. IMO any serious suspension upgrade for track use and you might just be swapping on a front end anyway so keep that in mind. There are tricks to keep that front brake effective and cool, but only up to a point.

Cheers Cooter , and what's up .
I have ridden HD's for the last 3 decades I had an RC51 but sold it a few years ago and always had a worked over XR650R with USD forks I grafted to it in the shed .
This dynojet #103 linear sensor I will look into (had a quick look) .Will read up more when I can. I have ridden HD's for the last 3 decades I had an RC51 but sold it a few years ago So I can short shift the HD's without a clutch but not slip change under full power and the RC51 had the best gearbox of any road bike I ever owned
The swapping drive ratio thing is just a thought it looks too labor intensive to me for the reward.
Most of those links seem XB dedicated but I saved a couple to my favorites thx again .
20W-50 it is then, thx. I like Amsoil and the Purple one in synthetic . I ride HD's so I know about running a straight weight oil , it was usually 50W with Evo's and Shovels .
I live 5k's(3Miles) from the Gillies Range in FNQ Australia and I have the Palmerston Highway (fast twisties) to connect to that or turn right instead of left and there's the Tablelands run to the top of Kuranda Range rd or I can link up with the bottom of the Kuranda range on the way to the Coast Road half an hour away that leads on to the Mossman Range rd and come back home 3 different ways on some of the best roads in Australia man. That is worth a google too Cooter. I am in sports bike paradise and have allways secretly wanted a Buell because of the it's a US Twin thing. Rode a few with the HD motors I really liked them ones just basic and vibey bikes , they turned in really well.
I've seen you on the XB? forums I think giving solid advice to some lads . I tried to join that and it didn't want to play for some reason .
So cheers and thx much appreciated .
P.S. This is what I was looking at Cooter https://www.rev-mo.com/product-page/...ter-sensor-kit apparently I can set a few other parameters with the dongle . We all have our favorite electronic solutions if we can access them.
Cheers mate
