(1) Has anyone here upgraded their RR unit? May be to a MOSFET type? If yes, will be great if you could point out the source.

(2) Also has anyone relocated the RR unit to a different location where it could get better cooling? It is located under the bike, near the EVAP unit, and I believe the airflow is really limited, especially if a sump guard is fitted.

Thanks!

1. Am curious to know the reason behind this upgrade? Does it improve performance?

2. I'm hoping that the heat sink is designed keeping this in mind. Some food for thought - are RR units used in car electrical systems as well? If yes, they would be housed under the hood and that must not be getting too much air.

As per whatever I have read up on this, MOSFET RRs run much cooler than the OEM one and are more reliable in the long run. Have heard of some of the RE Twins where the RR units failed and had to be replaced prematurely.

Hi guys,
Just picked up a preloved bone stock orange crush 2021model done 6900kms.

Got the full service done plus buffing by the previous owner.
The bike is still with the first owner pending paper work.

Mine failed within 2 years and was replaced under warranty.

I assume RR means Regulator Rectifier unit.
Heard of a few instances of them failing. There is no data or evidence to say they failed due to insufficient cooling. They have a heat spreader and its plenty enough to cool the unit.

Lakshmi turned 3 this past week and since I've started working I have been been able to ride as much as I used to. I take her to the office and back, so she runs daily but long rides have become a rarity.

I've always wanted to mod her but between and my laziness and the affordability of parts I've kept putting it away. I started with the CR7EIX spark plugs but I ended up never installing them and I'm waiting to buy racing cables for it to make sense and I haven't got around to it thus far.

I've been wanting to get the DNA Air Filter since I bought the bike, but I finally got around to it now. My Uncle was bringing back my grandparents from the UK and he carried it for me. It cost about 60 pounds including shipping.

The installation took all of 10 minutes. Needed an allen wrench and a phillips head screw driver.

I haven't been able to ride it around as yet but I can say this for sure that there is no discernible difference in the exhaust note.

The OE Filter Exhaust Note

The DNA Filter Exhaust Note

Here are some pictures that I took during the installation.





The airfilter and its packaging.



What the inside of the airfilter looks like. There's something shiny inside and I'm not sure what it is.

I've not really wanted to get the stage 2 kit but I guess never say never.

Thanks!

I would suggest using the stock air filter cover with the DNA filter. The engine really doesn't need it unless you are doing some track rides on it and then you would need other changes to go with it as well.
In stock form, the engine which is already tuned to run lean, will run more lean with this filter and the stage2 kit. Being in a hill station, the changes may not be that noticeable, but you would loose a bit of that initial torque and response and you will only get that intake roar when opening up and not much response to go with it.

Congrats on getting it done.

Most air filters have this internal side as glossy, perhaps to avoid dust collection.

Well, I think the closed loop fuel injection system will take care of it through O2 sensors. With performance air filters, one observation from the yesteryear motorcycles from Rx to modern day CBR is that they don't feed clean air {especially the high ground pollution in our country} to the engine. We've seen hoards of carbon deposits on Rx's piston with K&N {not sure if RE's performance air filter will be better esp in 2023}. They're more suitable in West where the pollution level is excessive in the Sky rather than ground.

Yes, the ECU will adjust accordingly, but from what I know from when fitting the FuelX system at RaceDynamics was that the stock threshold to increase fueling is not much.
I have also experienced it when I first fitted the W2S performance filter with the open bracket and took it for a spin. I was so disappointed in the way the engine was responding, that I came back home and fitted the stock intake cover back.

True regarding the dirty air being sucked in, which is one more reason not to use a open bracket.

RR unit on my bike is failed twice (in other words, battery health started showing red on console).

First time it was replaced under warranty along with the battery as they could not find the exact cause of failure. 2nd time it happened recently (few months back) and we bought a new one and replaced with old one at a garage run by our own BHPian - "LazyGunner". On another 650, the same garage is also relocated an RR unit to the front (under the front number place, between the down tube of the frame).

Also, discretely, there is been a slight change in the design of RR unit. Visually comparing the older RR units (2019) with newer one, there are minor differences in cooling fin, the cable thickness and orientation.

So yes, there is been issue for sure with the RR unit. Hope the new ones are improved and lasts longer.

Will stick with the stock cover then. Thanks!

Thanks a lot! TIL.


Here's a small update. I got off work early and was able to take a longer route back home. The throttle response is noticeably more immediate and that makes it fun and I feel a slight difference in low speed crawling uphill as well. Also the engine felt hotter than usual after the run and I did burn myself a tad. I find that a bit concerning to be very honest.

I still don't have an answer as to if the new filter is worth it. Once I do, I'll be sure to post about it.

Hi All, need some help. I had got aew t102 installed last year. Yesterday I was just fiddling around, checking if the air filter needs cleaning. I had never heard the exhaust without the db killer so just tried to test it .wasn't able to remove it so left it like that after I thought I had tightened it. Today while coming to office,somewhere on the way, I realized, exhaust was unusually loud; after reaching when I checked, yup, db killer was missing.

Long story short I lost the db killer in one of the exhausts. What are my options now? Do I need to get a replacment db killer from aew only or is it some standard piece which I can order off Amazon or some site. Please help. Thanks much in advance.

That is because the engine is running leaner now, hence hotter.

Check with AEW or order it off their website. I don't think they will sell just a single piece. Also they are not generic, since size and shape differs between manufactures.
