@@duck8280 I thought the factory quiz was quite good. But my ECU is also retuned and it might have been enhanced. Check with the link on my site and email Vcyclenut for questions.

@@bosqueblanco3744 it’s the optional race display.

I was told by a couple reliable parties that is was a Yoshimuna replica, one being the tuner who flashed my ECU, he had the full Yosh system to compare and tune. So that is what we used as the model for my flash. I'm extremely happy with the results. Now there are different headers on Ali-express. so not all are equal.

@@williamonthewestside thank you! I actually got mine a while ago and it does look kind of like yours in the picture you posted on the forum.

@@TrackAddict_nz interestingly I just did a few session that same day on a 2024 ZX6R, set up for the track with high end Ohlins suspension race slicks. I thought I would have liked it more than I did. I have more fun and confidence on the ZX4RR. Granted it is better set up for me. The ZX6 as set up had much slower steering and power was pretty Abrupt. I think it modded a ECU tune for smoother power delivery.

@@VoodooNinja96 I had CRST suspension tuning order and install it. They did a great job.

@@LoveMachined I love it. It pushes me off the tank a bit and much more securely attached to the bike, especially with the lower body. By control and arm pump are non-issue. It can be a little bulk at first until you get used to it. But I love it.

@@williamonthewestsidewhat’s a monkey grip?

Yes you do. They really are a ton of fun

Thanks for watching!

@@Teeny254 thank you.

My best is a 1:37 on the RSV4, low to mid 1:40's on the ZX4RR. Thanks for watching!

@@jacktupp1427 the track was completely repaved in July 2023. Unfortunately, it has gone through some hard use in the last year. I would love if they would clean up a few of the corners, especially turned too.

@@Teeny254 I greatly appreciate it. I’ll do my best to keep giving you new video and footage. Working on new angles, editing, etc. I plan to take some time to walk around each of the machines to give some detail as to what was done to them feedback, etc. thanks for watching.

@@williamonthewestside you are welcome sir

@@VoodooNinja96 felt very good. More composure and control. Only made slight adjustments. More dialing in next trackdays

@@maurosamarati9818 it is.

@@williamonthewestside Does it make a strange noise to you too when the fork is at the end of the race?

@@maurosamarati9818 no issues or sounds.

@@huseyinbayraktar5087 160/60-17. Same size at stock but a track bias race slick. Pirelli SC1

@@williamonthewestside Thank you, it looks wider than the stock tire. I wonder how the Pirelli sc1 would be if it were 170?

@@huseyinbayraktar5087 I also fitted a 180/60-17. Fits fine but won’t hit the edges on the track. If for street works fine and would look bigger.

@@williamonthewestside thank you

@@annabelloftime4210 so impressive for 399cc

@@metal8831 140ish

Absolutely fortunate. Thanks for watching!

It truly sounds incredible. I do have the DB insert in which only knocks down the sound a few percentages, but I think it makes a cleaner bark. About the closest thing you can get to a MotoGP bike and sound and feel form a near stock streetbike.

Based on your experience, I think you will love it. All the excitement and energy of the 636 with less of the speed velocity and risk.

It was Zoom Zoom. They are really good to work with

@@williamonthewestside thank you!

I don’t know what that means but I hope it’s a good thing 😉

To not have the neighbors complain and sue the track. Yes it’s silly. People moving next to a 65 year old iconic racetrack and then complain for the occasional sound.

2016 ZX10R front master cylinder. Guessing a 17mm piston

I would say it’s near perfect. Allows me to get into the power a little sooner and you can see, I’m able to hold each gear appropriately near the edge of power, but not have to shift to the next gear. I think stock gearing is too tall for the bike on thetrack.

If you can afford it, I would definitely say get it. Once you unrestrict it, it’s an incredible machine compared to everything else under 450 cc, Will seem like a superbike!

@@williamonthewestside Hella man. It is a big amount in Sri Lankan currency. Sri Lanka doesn't have that. It has to be imported from Japan or OC.I ride the ZX25R, but it doesn't fit me well. Will definitely take it one day and do full modification, install a titanium full exhaust system, flash the ECU and do more modifications.
