^^^ don't remember exactly. Will need to search for the bill, but it was not something that broke the bank :-)... Something like Rs.1,500/- inclusive of the seals & oil.

1500, thats a relief.. i think i also need to get my bikes suspensions overhauled...

Hey always glad to help a fellow biker anytime . One must keep in mind the following things though when visiting Kamla Yamaha:

1) First and foremost ensure that one takes a prior appointment before reaching there for service. They will NOT ENTERTAIN YOU OTHERWISE!!
2) Try and reach as early as 10 am if you want your bike to be serviced on priority basis.
3) Because of its service standards, the Workshop is always loaded with bikes for servicing so sometimes availability of certain spares is bit difficult to obtain. It is always better to consult your issues with XBHP ownership thread, enquire about the parts availability in advance from the service center, ask for Imtiaz. If the parts are not available, one can always procure it from other service centers and get it along with them for servicing and troubleshooting.
4) Layout all your issues and problems in front of the service supervisor at one go and post servicing do a small test ride. If you are satisfied with it only then accept the delivery post servicing. It is always nice to do a small tipping procedure for the small mechanics who have worked on your bike.. believe me they remember you the next time and take up your ride as a first priority to get done with (there you go revealing my trade secret to all!!)

This is the usual protocol i have followed since, the day i have been dealing with them and over the years have had a productive and good relationship with the workshop fellows. They are very prompt with their servicing and don't take a customer for a ride...however one should know what your ride needs and deal with them politely.


Cheers,

^^ u are one lucky fellow to have a gud SVC at ur vicinity

I gave my bike for service at Yamaha SVC here and they returned it after 2 days.

If that was not all, i found my bike even more dirty and dusty than before service. The security guard at entrance (where it was parked lonely) felt pitty on me and cleaned it somewhat with a cloth.

Till now i thought that SVC just do a wash job but even that belief was shattered to pieces.

Overhaul and other replacements

Hi all,

Been a while since I have updated about the R170. Anyways, we are taking the ride to SVC tomorrow to get the following things done:

* Get the lower gasket removed.
* Install the hotter camshaft.
* Overall overhaul of the rear swing arm and coneset greasing.
* Getting the electrical connections cleaned.

It has been observed that the Joelled R15s cannot crank properly with the 3.5amps stock battery as the decomps are not present with the camshaft. This may be one off case but the R170 indeed has a lot of trouble cranking to life with the stock battery. So we are replacing the battery to 5/9 amps AMARON.

Also the current map seems to be too rich for sea level conditions so with the help of Abhimanyu31, we will try and set a correct map to get the best result.

I will try and post the results after the necessary overhaul and changes takes place.. Under current circumstances, the R170 can beat the pants off stock KTM Duke 200 and Pulsar 220s and CBR 250r upto 120 kmph.. Beyond that due to rich mapping the top end kinda takes a hell lot of time to push through.. I guess with all the changes taking place, that should change. Will try and do a drag with a Ninja 250R and post results once the maps have been set correctly.

Cheers,

She's a DEVIL!! R170

Well,

we finally took the R170 for a thorough overhauling to figure out the niggling problems that has been troubling her for a while. Here were our observations:


1) The stock 3.5 amps battery is completely useless.. so we are getting a 5/9 amps Battery. Would recommend prospective to be Joelled riders who have opted for atleast BB kit along with hotter camshaft to go for this upgrade based on our experience.

2) the starter clutch Overou had gone kaput.. It was the main culprit which was making morning starts a complete pain in the back.. mind you though: this problem is specifically related to this bike only as the previous owner had not taken care of even basic maintenance.. Anyways, so got it replaced with a new one. Costs: INR 1200/-.

3) The clutch plates were not installed correctly. Got it disassembled and put it back with correct tolerances... Now the engine noise has also died down by a huge margin.

4) Unlike my earlier post, there was only one gasket installed at the lower block and not two like i had mentioned.. So gasket settings were fine.

5) The earlier custom camshaft was not installed correctly.. As a result there are signs of the camshaft getting chiseled at the edges... And may be adding the decomp unit by my friend was also sapping a lot of power from the set up.. Hence, the knocking problem and the ride refusing to go above a certain RPM on 5th and 6th gear as mentioned in the earlier posts. The newly designed camshaft sent by Joel is definitely lighter and of different design than the previous gen we got that installed and this time without the decompressor unit.

6) The current map is too rich. The piston was covered with black soot gooey, the spark plug had to be replaced with a new one as the earlier one failed.

7) We replaced the old gaskets with new ones (Genuine Yamaha). Also the piston pin has been replaced. After dismantling the block, the Cylinder walls and the piston and the rings are absolutely fine and so are the inlet and exhaust valves..

8) After they put back everything together, the coolant was topped up, the clutch cables set back to proper settings and oiled and chain was lubed properly

I really couldn't push the R170 today due to wet road conditions but now one can immediately feel the difference in performance.. She is now literally flying through all the gears easily till 8000 rpm and was beating everything on road. I couldn't push beyond that. But rich ECU mapping is indeed effecting the top end performance. joel was available throughout to help me out in understanding and ensuring that this time all re-assembly is done with proper instruction and as per his pointers. Joel is also sending new maps with correct setting as per sea level to ensure that the fueling is not too rich as in the case currently we are facing..


GOD BLESS Kamla Yamaha, Mumbai!! .. The SVC head had assigned 2 mechanics specifically trained on Yamaha r15 specialising in engine dismantle and re-installation, just on this R170 and was personally hovering around to ensure that the task he had undertaken was completed with top notch standards and to my satisfaction.. and they did deliver..

The video of an engine crank test post the overhaul:



It starts just like the stock bike.

Below, I am attaching pictures for all you guys to have a look at:

01) Burnt out Starter clutch Overou. Replacement Part: Rs. 1,200/-
02) Custom Big Bore piston for 173cc BB Kit.. notice the gooey black deposition on the surface.. happening because of rich tuning.
03) The SVC Head personally adjusting the Valve clearances as per Joel's specification.
04) The Inlet and Exhaust Valves.. excessive soot deposit because of rich tuning
05) Spark plug.. too much soot and rendered useless so replaced it with a new one
06) Piston inside the BB Cylinder
07) Re-inserting the BB piston carefully back in the cylinder after judiciously oiling the piston rings and the insides of the cylinder wall
08) Re-inserting the new Starter Clutch Overou along with the whole assembly
09) Another view of the piston inside the BB cylinder
10) Genuine Yamaha Gaskets both for lower and upper ones.. the lower gasket is of paper material and costs Rs. 65/- and the upper head gasket costs Rs260/- and is fully metal


Cheers,

Get the Amaron Pro-Rider 5A , its a direct fit.No Modds required. Its has no issues at all on my bike for over 2yrs.

great stuff..... Now waiting for performance timings after proper mapping...

I am still waiting for my 180cc kit. ... waiting... waiting... :-(

Then yours will definitely be faster than the R170... i guess you will have to ask for the new hotter cam... it is lighter and definitely lets the engine rev even faster..

Cheers,

Been running that for the past few months, I think? 62.25 mm piston works out to 179.something cc's (according to my calculations). Done around 4000 km's on it, lots of vibrations to begin with, after a few oil changes and a switch to FS 15w50 have smoothed things out a lot, the next and I guess final round of mods for me are around the corner, TB, Injector, maybe more head work and a hotter cam, I hope to have the time to do this at Joel's workshop, along with a dyno run or two. I also run homemade octane booster to give around 95-97 RON from the 91 RON Indian Oil, the other pumps around here only give 87 RON which is BSII, this gives instant knocking.

Can u please share with us how u do this? Will be highly appreciated. Thanks.

Get the 32MM throttle body with all 3 pcs and a 10 Hole injector, untill then you will have all Hickups and cold start issues. Port your cylinder head according to the bore-up kit, you should be running near to stock in comp ratio else you are sure to screwup something. Coz you are using your bike for daily use and not for racing. Also fueling will not be an issue at all after head porting. (Go for elliptical porting it works awesome for R15)

Hi All,

Its been a while since i have posted any updates regarding the R170. Seems the stock bike was so badly kept that when me and my friend troubleshoot one problem some other irritating problem crops up! This time right after i had got her back from the SVC. She was running fine. After a week the R170 just simply stopped responding to the starter button no matter what we did. I was scratching my head over it wondering what now? Howcome new issues right after a visit to SVC? Had a long discussion with Abhimanyu31 and Joel, RC as well to identify the root cause of the problem.

Initially we thought that the maps need some major corrections with idling values for the RD Powertronic ECU.So after almost 2 months of major sabbatical, my friend finally decided that it was better to pay a visit to the SVC. Kamla Yamaha, Mumbai being best in the business was called in for help. The head mechanic took just 10 seconds to pin point to a burnt up starter motor. According to him, my friend was unfortunately given a lemon by his cousin as the head mechanic had recently opened up the engine in my presence and the kit and the crank and the overall engine is absolutely fine and in good condition. Even the front shocks are in bad shape and need oil seal and fork oil replacement.

So friends, an important lesson: make sure that if anyone of you are planning to go for this insane upgrade from RC, your ride or your friend's stock bike should be in good condition. It is a must!! Or else a bad conditioned R15 is bound to give you troubles and may result other problems worse engine seizure!

Anyways, post installation of the new starter motor. She is frekkin flying to 100+ in a blink of an eye. So much so that she did wheelies in the first 4 gears. As per the reports from my friend, upto 120 kmph no one can touch her but beyond that she is taking too much time or just not moving ahead so i guess some more tweaking in the map will bring out the real monster in her. He just had a blast decimating a few Dukes on his way back from the SVC.

Right now R170 is running a pig rich map and returning a FE of 27 kmpl. For Noobs who are scratching their head and palpitating over why so less FE.. understand one thing... this bike has been tuned specifically to generate more power and speed and FE is the last thing in the mind!!

What me and my friend have also come to realise that in the pursuit for more power, the ECU being an open loop one, the rich tuned map is very sensitive towards atmospheric changes like, sudden drop in temperature, air pressure and other variables. So a major dip in temps or atmospheric pressure etc. also effects the performance of this extreme build which may not be the case so with the 165cc kit for R15. This current build is as close to a race spec bike as possible hence with so much power an upkeep with tuning is required at times too.

Also if i am correct, the older gen of RD Powertronic ECU didnot have a sensor to measure atmospheric changes in temperature, air pressure etc. which the newer gen of the same ECU is equipped with which makes a lot of things easier.

I shall give you all a detailed report once i am back in Mumbai.

Cheers,

how man....please tell us too..
