Re: Race Concepts - Next Level performance!

hi i too same issue with RC ffe( loud screeching noise) ,so reverted back stock exhaust for time being and to my surprise i feel no drop in performance with stock
i just want to know if glass wool is completely burnt out will there be any drop in performance
my ride rtr160 with RC bigbore, modified head intake

am yet to followJuris method




@juris can u guide where did u got ceramic wool
thanks

Re: Race Concepts - Next Level performance!

I am no expert on this matter, however my two cents would be that the extreme vibration and lack of barrier between the ffe's inner pipe and the glass wool (I say under the assumption that you only stuffed glasswool and didn't use a mesh first to protect it) made the glass wool disintegrate and get out of the ffe in that short a distance.

Please refer to [MENTION=28676]Juris[/MENTION]'s thread for the right procedure on repacking a ffe. It will make a huge difference wrt durability.

Btw great durability you had earlier, with the 5k change period. Could you please throw some light on the process of repacking you used then...

Re: Race Concepts - Next Level performance!

Hi!! I am new to this thread.
I refilled my RC ffe like 5 times till now in 20k kms, I used to refill mineral wool which used to last good 5k kms and then the noise instead or sound used to come. A very close friend of mine who manufactures glasswool and heat absorption material like ceramic bricks and all, he suggested me to go in for ceramic blanket which can hold upto 1200 degrees centigrade. So now after that I haven't tried it on the highway, but within city limits the end can doesnt burn ur or ur chicks leg at all and the sound is also quite bassey, the only issue I have is that when I refilled the ceramic blanket last time I had put in normal amount of blanket inside but within 10 days the blanket started coming out of the holes that are there in the pipe, plus the exhaust note became veru trebleish, so I again opened it and saw that 1/4 of it was gone, so this time I pushed and packed the blanket so tight that even the end part wasnt going inside. Hope this time it stays well. When I went for the BIC track day then I had got some yellow colored glasswool filled in emergency as I rode down from kanpur to delhi at continously 120 110 kmph and by the time I opened the can there was not even a single thread of that glasswool inside it was all gone, gone completely. I was shocked to see that. How is it possible? Can u please help me out with this issue?

Re: Race Concepts - Next Level performance!

Do give the ffe repacking a try, you will notice a lot of difference, exactly what [MENTION=28676]Juris[/MENTION]'s thread name says, from noise to music :thumbup:

About the life of repacking, initially I used to use only glasswool and that lasted for about 1200kms for me, did about eight of these repackings. Tedious work to keep repacking,

Then I tried ceramic wool like the one mentioned in juris's thread. With ceramic wool the noise seemed pretty much good for about 1800-2000kms ,did many of these too. Tired of the work for repacking I didn't bother to repack the ffe for the past 4000kms , but recently after loosing my baffle and the simultaneous occasion of me being bit by the riding bug again, something had to be done about tht harsh screeching from the ffe

Thing is both glass wool and ceramic wool are mainly for use in static objects and their use in a vibrating environment makes them degrade quite fast and hence the frequent repacking. Recently read about durability of fibre glass wool and luckily I could source some hence gave it a shot, done about 1200kms so far and it still sounds sweet apparently fibre glass wool should last for an eternity but well let's see

Re: Race Concepts - Next Level performance!

Here a short video of re-packing the exhaust.. Glass wool does make wonders..

Bro.. it depends on the quality of the glass wool you use for the filling..

Re: Race Concepts - Next Level performance!

Great post there Juris.
Thanks for posting your ingenious research.

I am using FFE in stock form only and I also do have the DB killer but it's shape is kind of of distorted.
Here it is what happened that while riding on highway the DB killer popped out and a truck ran over it.It became a plain sheet of steel after that.
I went to some welding shop and got it correct as much as possible but after that I haven't got the performance at par with as it was before.

Well I am pretty much thankful for the Ffe filling info that you shared with me .Maybe I can give it a try.

One query 0- For how long will 1 FFE filling last?

Re: Race Concepts - Next Level performance!

Re: Race Concepts - Next Level performance!

Firstly, have you been using the ffe in stock form or have you tried filling it with glass wool/ceramic wool.

If you have not done any packing for the ffe previously, please search the DIY section of the forum. IIRC there is a thread on ffe repacking, follow the same procedure and you will get great results. Once you go through it if you still got any queries do let me know.

I personally used a combi packing of steel mesh, steel wool, glass wool, fibre glass wool, glass wool in the same order and got some great results.

I got it what you meant!!!

Thanks for the information on DB Killer,anyways I knew I have a long shot on getting a new one now.

Anyways can you please spread more light on this FFE Packing you are talking about?

Re: Race Concepts - Next Level performance!

Ahhh sorry to be the bearer of bad news my friend.. you can kiss goodbye to your db killer hopes.
I recently received confirmation from RC that no more db killers are being manufactured, as a matter of fact I was recommended to keep an eye out for a "new ffe with integrated db killer"

Seems like the best way to fix a rs.750 problem is by spending rs.7500 . Way to go RC :thumbup:

Btw: I'll get in touch with you, I got some plans for RC . The more members (plaintiffs) I get , the better


Edit: until you get a db killer or are able to find an alternative to it, might I suggest you try some different kind of packing for the ffe.

Tired sick of the amount of disturbance the loud noise was causing to others, just last week I tried a new ffe packing and it is working great for me now. The horrible treble screech is gone and now I have this nice smooth base like sound from my ffe without any damage to the bikes performance

Re: Race Concepts - Next Level performance!


Aaahhhhhhhh..... Diplomatic Silent Killer :P

Re: Race Concepts - Next Level performance!

I personally have not faced any problem but I was planning to pick the RC kit from a long time and haven't picked it till now just because I trust my peer group, if you know what I mean. My close xbhpian friend [MENTION=37862]snehithpereira[/MENTION] from Bangalore (read Bangalore) has been trying to get a DB killer but in vain. So you do the guess work.

Re: Race Concepts - Next Level performance!

I ordered joel DB killer for the FFE on my FZ16 by this January 2013.

He asked me to deposit 750Rs in his HDFC account as usual and I did.I waited for the parcel to reach for 2 weeks.After getting out of patience I called,emailed,messaged him to send me the DB killer and every time he said that I am right on it to send it to me.

Till date I haven't received it.
Definately Rs 750 is not a big amount to loose but definately my trust has been lost in him.I had planned BIG BORE KIT for my fz16 but had to stall that thought due to trust conflict .

Guys if any1 of you have faced this problem then please let me know or if there is some solution to it??
