    I ended up with a similar pig tail for my MTB wideband O2 sensor too ! 👍

    Yes, they both operate on a % duty cycle change value. So +X value in one is similar to the other.

    Well RB can claim whatever they like. I had my 5th gen running PC3 with custom dyno tune before RB install. I ran it for 500 miles on narrow band and it was nowhere near as good as the custom tune. So I bought a wideband AFR sensor & fitted that to the dash temporarily. I used it to modify the cells where it was out of whack. It got much better very quickly. Would have been better if I'd had a logger. Took it for a dyno run & it was still off a bit. Fitted an MTB & it was much better, next dyno run was much better. YMMV

    The problem with the lambda sensor tuning is its fixed for 14.7 AFR lean running state. It only sends rich or lean not actual AFR values. Thus it can correct areas that are rich or lean but not set a specific target AFR you may desire. The wideband sensor MTB allows you to set a target AFR & it will auto tune to that target.

    Racebolt UK do a couple of full Ti engine bolt kits. https://www.ebay.co.uk/itm/Honda-VFR800-98-2009-Titanium-Socket-Cap-Engine-Bolt-Kit-/303933918551?_trksid=p2349624.m46890.l49286 Either the cap heads above or with hex heads drilled for lock wiring.

    There is an RBR map for a stock bike & maybe with a slipon. Other than that you need a dyno a wideband logger or an MTB.

    Bicycle lights are getting way to bright with the LED revolution. Some of them could do with a hi/low beam switch. I've been blinded a few times now by bikes cycling the wrong way on cycle lanes next to the road.

    No they have been upgraded, same lift more duration.

    So HighsideNZ has a 5th gen engine in 6th gen frame, with a 74mm bigbore & all of my mods for 140hp. I have a lightweight 5th gen circa 205Kg wet, with 120hp. I'd like to do more to it, but time & money always arrive independently ☹️ I never seem to have both at the same time. Happy modding 👍

    Hey Wacken, the RBR uses a variable table like the PC. And it is a % +/- add/remove duty cycle system too, same as PC So you can pop any PC map into excel & then select what you want from the PC & drop into the RBR map for the same cells.

    Oh in answer to the question, Yes. VFR Stanchions, VTR sliders, Traxxion Dynamic Cartridges & CBR929 callipers 👍😎

    Well using 7.5wt oil is the major problem. You have a valve system that is around 20years old. Depending on mileage & fork oil changes will determine the amount of wear. They were poorly damped when new, so using 10 or 15wt oil would be a good start. Then it’s a choice of either upgrade the valves or the cartridges, or replacing the forks. There are plenty of threads here on how to or what worked for others. Have fun 👍

    Just to qualify this particular wheel After investigation was discovered to be a hand me down from a sponsored team to the team where it broke, it was IIRC a magnesium Race wheel & had been crashed a few times & NEVER x-ray/dye checked. That’s why cheap secondhand race wheels should be avoided & magnesium ones never used on the road as there are prone Stress fractures. And on broken spoke on a marginally strong wheel is all it takes to overload the rest !

    Looking good, enjoy & summer is nearly here 🙂

    A tip for those clamp springs, get some heat shrink colour of your choice & slide over the springs. It keeps the exhaust free of marks & rust from the springs, they will rust.

    Just found these whilst looking for something else. Enjoy.

    Great shot on the bridge. Good use of the lockdown 👍 I consider bike riding to be essential & thus my riding is in compliance with the UK gov advice. Plus I’ve had the virus, so consider myself immune for a bit.

    You don’t need the timing marks for valve measurement. Just look at the cam lobes, when the tip is opposite the bucket, you can measure the gap. If you need TDC for cam removal/install then a piece of alloy rod or a long screw driver down the plug hole will give you TDC indication. If you use the paint method as advised by Honda, you can count teeth from the head face to the painted teeth ends. There is always a way if you put some thought into it 👍

    I’ve had Traxxion Dynamics AK-20 cartridges & springs in mine for 10 years. Plus a Nitrox Race shock on the rear, with the brake delink & loss of 35Kg it handles & brakes like a CBR600RR now 👍😎

    YSS Fork Spring Table View File Having spent ages trying to find compatible fork springs for an older bike, I came accross this list on the YSS Thailand site & thought it would be a great cross reference for anyone looking for a fork spring, when they can't find what they need for the specific model ! I had planned to use VFR springs to improve my buddies FJ forks when I refurbed them, but turns out Yamaha use a thicker wall on their 41mm forks, so the VFR springs (35mm OD) won't fit ! I was able to use this file to cross reference the early FJ1200 spring (485mmx33.5mmx0.65Kg/mm) with an XJ900S from 94-03 years which is 490mmx33.5mmx0.8-1.6Kg/mm (progressive), so only 5mm longer but stiffer, just what I needed 🙂 Hope it helps others.

    I’ve been using just wide Band for years with my RBRacing module. The narrow band sensors are just looped together on the RRR harness. I use both the original O2 sensor feeds to power the MTB wideband sensor, you have to use both as the Wideband sensor draws to much current for one feed to supply it. As an FYI You only need power through on stock O2 sensor feed to keep the Fi light out. Because the alameda signal is not seen the ECU defaults to a rich map. It is this map you use the RBR or PC3/5 to correct. Have fun 👍

    And if the package got lost you could only claim insurance for the stated value ! Just saying ☹️

    Finally got all the bits to fit my uprated FPR to complete my throttle body & airbox upgrade. Then updated my other threads about both elements 👍

    Skinny tires handle the best. I had an ANF125 (modern C90) as a winter run around a few years ago. I used to think my CBR600F4 handled well, until I rode the chicken chaser. It may not be fast but what a blast, in the wet on the roundabout near my work I could get it into a two wheel drift at 30mph, fantastic. After a few months riding that in the winter, getting back on the CBR was like steering a barge. So don’t knock skinny, they definitely handle the best 🙂
