Argh the more I watch the worse it gets

Haha thanks. Don’t worry, I didn’t wash the cylinders! But I was soaking the buildup around the butterfly mating surfaces. That buildup was causing the throttle to stick closed and not open smoothly. Just after I shot it with cleaner, I used a light abrasive pad and cleaned it all out from the throttlebody walls. Much smoother operation now!

Thanks! As for further tasks, I’ll just be adding slicks and making the side fairings from carbon… taking this to COTA in the spring! Send me an email about the bars Extramediumskills@gmail

Making the engine more efficient with a brand new surface on the bored cylinders combined with the 13.5 to one compression ratio made a huge difference. More air and fuel were allowed in and was burnt more efficiently. Additional 15 cc were added to the bore, which made the motor more over square. Check out my later video titled “the battle for first” and you will see how much stronger this engine pulls than a stock motor with a jet kit/exhaust…. Even when I was turning this fat 180 section tire!

@@Extra-Medium-Skills Are the rings thinner than stock on the kit you used?

Thanks John, love your engagement. Not mad at that comment; I totally try to get better with each new project. Will you chime in if one of my future pieces looks better? Hope to hear your objectivity! See ya at the track maybe!

Thanks mucho!

It rides well so far. Will track it in feb or march. Thank you!😊

The tank and headlights are worth more than I paid for the bike. The seller gave me a great deal; good guy

I feel I’ll need to remove and clean every part eventually. No real damages or anything… just old dust & dirt

@Extra-Medium-Skills Same here, only some corrosion and broken plastic on mine really. And I'd like to repaint the frame the original color.

Thank you!! Very excited to have this in my collection

Thanks a lot! I love making my own parts

You’re welcome! Simpler the better, right?? More to come my friend

Find a good machine shop first. Check reviews on piston kits as well as the forums for info.

I run 14/44 on my racebike. But, I have a 180 rear tire. The larger the front sprocket, the higher your top speed will be, assuming same size rear sprocket.

Thanks so much! It’s a fantastic upgrade if you don’t want to move up to 300 class

Thanks so much! The geometry is something I need to do a better job of explaining, for sure. Basically minimizing the input of the arcs to keep the deflection of the stroke to the minimum. If I think of a way to explain it better in a video, I will do so!

@Extra-Medium-Skills Yes if you could do that it would be pretty useful, l am trying to adapt a yzf r125 swingarm to an Aprilia RS 50 and i need to make upper shock mount and Lower link mount points but i have no clue how to adjust the lenght of all brakets to have a correct geometry!

Hey Corporal, good catch, I misspoke but cannot fix it without removing and reloading the video. For those reading, it’s obvious when rebuilding which way the head goes on, just match the domes to fit 👍🏽😁👍🏽

Ain’t tryna brag…👍🏽😁👍🏽

I made both!

Thanks and welcome! Glad you are watching!!

Definitely JC! Lemme know if you make it in November!

Thank you kindly, señor

94-98 VFR are the narrow ones!

@@Extra-Medium-Skills cool is that the 750 or the 800? Also what socials do you use so I can send you some pictures of my RS project?

@@kavonmchellon4651 send to my email extramediumskills@gmail.com ! Can’t wait to see. Also I think these VFR models were 750👍🏽

Thanks much! Hope to be a “fast guy” by the time I die 👍🏽😁👍🏽

Thanks! If I can figure out how to fix it I will. Appreciate you watching!!

These are from a 2006 Gsxr 600

@@Extra-Medium-Skillsthank you!!

Also if you want the single side swingarm look there is an older model 125 that has em, a bit of a pain to find the parts but look pretty neat, although I'm abit biased cuz I have a similar swingarm on my 50

@kavonmchellon4651 I’m pumped to hear about your similar project!!! Feel free to send me pics of your build I can share on vids!!! Keep me updated.

Thanks JC!!

The old ex500 motor is much heavier though… but I’d love to see your finished project!

@@Extra-Medium-Skills just on the drawing board at the moment

Top speed won’t change much, but will be possible with higher gearing now. Acceleration is the goal vs the stock 250cc. Check out my short vid just posted to see how much faster this is than a stock motor!!! ua-cam.com/video/RmlOmhIb63w/v-deo.htmlsi=TyCp89WkM0wCJTwk

Huge main jets and stubbed needles were part of the tuning. Only other mods were port matched exhaust to the gaskets and a full 30mm inner diameter header

head gasket or cylinder gasket thickness should change or keep just stock ??

Yes, the piston kit will fit that year too.

Thanks haha! Always improving… but enjoying every minute

Good point @ryancorbett-d5x! For this particular epoxy, I use volumetric measurements. The manufacturer suggests volume bc the density of each part varies. But totally true that epoxies can be weighed very accurately with cheap scales! Great budget hack 👍🏽👍🏽

Neither confirmed nor denied 😁

Thank you! 😁

Great idea! I’ve not used expanding foam in a project yet, I’ll put it in my to-try list 👍🏽😁👍🏽

Deff love using prepreg. I’ve used that for case covers and it is great!

Right on! I hope you happen upon an amazing deal for your next bike!

@Extra-Medium-Skills thank you I'm sure I will

…not to brag, but y’know 😉

Thanks so much! I agree vacuuming and a real mold would be the best! I aim to do a higher quality vacuum part sometime in the winter. Lots of good instructional videos out there. You made great points! Stayed tuned my friend!

Thanks much! I think you should try racing. I believe my average time at Hallett is 1:39 At track days & 1:37 in races. Both CMRA and Legion have their own license programs. But since both are AMA sanctioned and offer reciprocity, you can use your license to hop into a race in either organization if you want. I think you should do it!

Thank you so much. It’s a great feeling when you actually get a good deal every once in a while huh I’m excited to see your video.

👍🏽😁👍🏽

Almost…

Good tip! Thanks Rick. For track day or street build I agree with @rickbates9232 , sadly I cannot employ pods or lone velocity stacks since I am required to have an air box which receives PCV gases according to tech regulations 😏

Thanks Rick! I will try to find a dyno to get some numbers; great idea! The bike is 306 lbs or 138kg

@rickbates9232 Dyno run coming in September 👍🏽👍🏽

@rickbates9232 yep, I chose the 64mm for less risk of failure and/or heat dissipation struggles.

@kyleegan-op2xo thanks so much! I’m genuinely glad you stayed tuned in! Funny, my editing skills are definitely not best, not worst, but extra-medium level 😄 I promise to keep content real 💯

Thanks 👍 I am addicted to carbon fiber (as one may conclude after seeing my Daytona in previous video😄)
