Don't get surprised 0-60 lap quick i heard is 3.4 seconds on Stock TVS by 2 of xbhpian

And I am waiting for Review do inform me when its done.

Congrats mate!!! Can exactly understand what the feel is as I have been using the big-bore and FFE since ~2.5yrs now.

Mine is ~5years old RTR160. Been ~25000kms on this setup and it actually is a super value for money(what i paid then back in apr,2010). Was about to sell off my bike as stock seemed a li'l slow but this setup has kept me happy since and still it manages to bring a smile to my face when am touring/riding with my ZMA/R15 friends...getting the drift?

I didnt get enough time to make a proper video of exhaust note or even try to properly enjoy the new kit.. had a micro puncture which was dragging the mileage down & now the air leak from rim, possibly a bent rim.. & got the carb tuned properly with great difficulty too .. So once its in perfect condition & its giving proper mileage, a detail review should follow btw.. stock one doing a 3.4s?? Only a speedgun & flat road can reveal the truth

2.5yrs?? Thats impressive man! I was trying to contact long time big bore users before I got the kit but I could find many.. anyways good to know that you are enjoying to the core as I told above some or the other issues have been nagging me & I have to get it all fixed soon & have a proper long ride

Yes bro. I'm one of the two RTR guys. I have managed a 3.4 on my stock RTR . With the 190 I'm very sure it can touch 3.1 atleast

do post updates as you continue clocking miles.. this update will also help noobs and critics to analyse how is the power up kit performing with your respective ride. just don't let your new thread go dead in the middle. happy riding.


Cheers,

Good to know .. I m not so good at 0-60 .. will attempt next time I get a chance..

Thanks man! I was quite busy & as you can see above, I was facing quite some minor problems with bike.. now that I fixed many of those, I can review properly..

& here is a video of exhaust note comparison of stock and FFE.



Some details,
This is just an exhaust note comparison of TVS Apache RTR 180 stock exhaust and Race Concepts FFE (with dB killer) & not their performance.

Both the videos were shot in same location with almost exact same surroundings to get accurate comparison. One more video comparing exhaust note without dB killer will follow.

By measuring the sound level captured (with some error margin),
At idling, RC FFE is twice louder than stock.
At 3000rpm, RC FFE is more than three times louder than stock.
Couldn't get accurate measure at 6000rpm, since both were quite loud but needless to point out which was louder .
Other than just being loud, the exhaust note has more bass with RC FFE.

Don't mind please!! It's written For Track Use only...lol....and you are using it on street !!!

How much of power difference do you see now??? how much of more kmph ?? pick up ?? etc??? Does braking is still efficient for the increased speed??

Most after market exhaust are 'For Track Use' only. Don't believe it? Check out any of them, including Akrapovic, TBR, Yoshimura, Leo Vince to name just a few. The reason; they do not meet the emission and sound norms. Still I am sure you will have noticed quite a few super bikes using them. Why? 2 reasons; first, reducing weight; second, to get rid of the cat con and improve gas flow.

Rightly said by Abhimanyu, but you got one thing wrong about RC FFE It MEETS the emission norms! I got an emission test done after getting the kit.. it was well within the limits.. so no issues there.. only thing is it might be louder than the permissible level if the dB killer is removed..

@somen : If by pickup, you mean 0-60 timing?? I have to test it yet.. But the overall improvement in performance & smoothness in engine is obvious when you ride it.. & no issues with braking.. stock brakes are good enough..

Very very sorry for the irregular updates! Here is one after 2200kms with the new kit..

Because of a lot of issues (nothing to do with the new kit) like tyre punctures, air leak through rim, wrong carb tuning (blame myself for it ) and busy office schedules I was not able to test & post reviews properly.. so here goes..

Fuel Efficiency : With a somewhat lean setting which I had when I got the bore, the FE was 47kmpl (90% highway), it had minor hiccups in low rpm though. Later, with the Carb needle set to rich and some fiddling with tuning, i was getting 35+ in city. It is not fair to compare the mileage I was getting earlier in stock setup (40+ in city), because I ride completely different now, rev more than before. Mileage is yet to be tested accurately for highway only case, but once I got 40+. On a recent ride, got a mileage of 37kmpl which had 30% city & rest highway (almost 80-100kmph throughout the highway).. which I consider is decent..

Power gain : The power gain is pretty evident as soon as you shift onto first & rev it up. After 4k, it simply shoots upto 7k+ in no time, which is very handy in city to overtake or when you feel the need for speed! I dont how to put the power gain in numbers, you have to ride it and feel it!

0-60 test : I must say, I am quite bad at this.. also a bit scared of the wheelie when started at 5k+ rpm (which never happened to me in stock)..

Top speed test : Reaches till 110kmph faster than before, but there seems to be power loss after that.. which I think is because of somewhat leaner mixture at higher rpms (since I am still running on stock filter and carb) hence unless I upjet the carb, I guess topspeed improvement wont be evident.. Managed to reach 127kmph once though.. Currently in talks with Joel on what is to be done..

Changed the front sprocket from 14T to 15T today & my reaction was "WoW!" what a change! There seems to be little reduction in acceleration in lower gears but I am a slow revver .. I am sure there will be significant increase in top speed.. earlier in 5th gear, it used to do 54kmph at 4k rpm & now it does around 59kmph.. it used to do 65-66kmph at 5krpm & now it does 72-73.. couldn't measure it accurately since I was riding in city.. With proper upjetting, I am sure it can do true 140kmph The bike is now like a tamed beast.. doesnt just lunge forward when revved.. which I miss sometimes though will post updates on the new sprocket soon..

Here is a short video of a casual ride at NICE road in Bangalore, as you can see it was never redlined.. This video was done mainly to check how the video from mobile mounted on helmet comes out
It does 100kmph at around 7.2krpm & 112kmph around 8krpm.. 123kmph was done while sitting completely upright without any crouching..
This is with 15T front sprocket..

Later reached 127kmph without crouching & 129kmph once with crouching.. there was traffic which anyways wouldnt have let me go any further.. These are not in video..





This was done when the carb was still not properly set and with an antique 13000kms old spark plug.. changed the plug to NGK CR7E GP (Platinum not Iridium, so just plug & play, costed 168 bucks) which is recommended for RTRs by NGK & oh man! the difference it made!! The bike simply revs with no probs at all.. was also able to get the carb setting right with this.. It starts at first crank with ease! I was simply suspecting carb all along .. The next proper topspeed run will be done soon with the same setup ..

Where are the Joel'ed RTR owners in xbhp??? I have some queries, please help me out! & also do share your reviews so that it can help whoever is going to get these kits..

For now, I wanted to know the reviews of 33mm carb that joel offers and also the high lift cam shafts?? Has anyone tried it (specifically for RTRs)??

As mentioned earlier, I am currently running on stock carb and filter.. only big bore, headwork and ffe was done.. Have any of you been successfully able to tune the stock carb for the same setup?? I m not able to get the proper tune.. Even with the needle clip set to rich.. I seem to be missing something.. there are some backfires which are consistent from 6k to 4k rpm.. and also the top end hasn't improved much, even with 15T front sprocket.. The overall power bump is pretty obvious as soon as one wrings the throttle but I would like it to perform at its best.. Please share your views and opinions!

Mate check out the FZ18 or Rylan's thread, it should give you an idea what a 32/33mm semi flat D slide type carburetor can do to your ride!!

Rejetting never works out well for any ride as far as i have seen. one always witnesses flat spots which i guess is the case with your ride. Upgrading to a bigger carb is a must then

Cheers,

Thanks man I have seen that.. & I know it will make both me & the bike go crazy! & it definitely makes a lot of sense for FZ since there is 30cc engine upgrade & stock carb is bs26.. but for mine, its just 10cc extra & also the stock carb is 29mm.. even Joel is suggesting me to try out with stock filter & carb itself, saying its more than enough.. But I am not getting the perfect result from my bike..

Like you said, I had flat spots at 3-4k rpm but it was resolved by setting needle clip to rich..but still there are some backfires.. & there seems to be some prob in top end.. the acceleration after 110kmph is not that great.. Reached only 129kmph till date.. I also increased front sprocket by a teeth..didnt do much of a difference in top end.. just wanted to know what fella joeld RTRs did for their ride to make it perfect..

Also I got the new NGK G power plugs recently & it made quite some difference as my earlier one was 14000kms old.. didnt get time to try out top end with the new plug.. Will check with it & post it here..

By looking at new FZ18 threads shooting up, I feel soon there will be more no. of FZ18 than FZ16 in xbhp

Hi all,


Reviving an old thread, an update after a long time, after 6000kms to be precise


It has been a good journey so far & I had no probs with the RC kit as such.
No issues performance wise, but was a bit concerned with mileage as I never got above 35kmpl! Only other minor issue was the loud backfiring which I felt irritating many a times.


Got a brilliant suggestion from @shv18 to check glass wool in the exhaust. Got it opened & saw that only a handful was left & that too stuck in a corner of the exhaust! Got it filled fully & then when cranked, I realized this was the sound it used to make when I got the exhaust!! Bike became much more vibe free & low end torque definitely got a bump! Also backfires reduced significantly.


I was expecting the mileage to improve after the glass wool fix but it is still the same. Went on a short ride of 100+kms & got a mileage of 32 which was mostly wide open throttle throughout the ride. Shouldnt it be higher than that??


Dont mistake me for being a mileage guy the only reason I m calculating it because it is an indication that things are fine!


I was able to hit 122kmph in 4th gear itself but only 130 in 5th, looks like bike is a bit overgeared with 15T front sprocket!

There is another issue. Whenever I ride at Wide open throttle for sometime & let go of throttle, there is an instant when there is sudden deceleration (like someone applied brakes or the fueling was cut off) & then normal deceleration continues. What can be the problem? Something to do with carburettor?? I feel this is the culprit for reduced top end and also mileage!

Also now with glass wool filled exhaust, shouldnt the carb be re-tuned?


Earlier, the needle clip was set to richest setting (3rd position) & also a washer was added to make it further rich. Yesterday I reset the clip to the centre position with the washer below so effectively it is like it is in 3rd position. No flat spots anywhere but there is a difference in acceleration and exhaust note, but difficult to pin point if it has improved or degraded . Yet to test the mileage with this setup. Will retain this config if there are no signs of leanness in engine. Regarding reading spark plugs, since I stay in city, I always find it tricky to read, since I can only find the tuning of first 1/4th throttle.


Also I tour frequently so is the semi flat carb recommended? I read it needs frequent tuning & is prone to atmospheric changes, humidity & stuff. This was the only reason I didnt go for it yet!

Please help me out here guys!
