HAHAHAHAHAHAHAH
Haryono is a ripoff merchant. My advise is to steer well clear of Haryono and his Automotivesparepartsshop crap.

I bought his FZS "plug n play" 200cc big bore kit and big valve head with cryo bronze valve seats. I paid in total over US$2000 in December for the kit and other upgrade parts.
After waiting over 4 months for the head to arrive, It did....Unfinnished.
with broken cooling fin, bent cooling fin, cracked intake port runner where the valve guide was screwed in, a partially ported head, missing valve train (rockers, springs, spring washers, valve keepers, cam, cam bearings (X2) tappets, fasteners, head X bracket/cradle)
Wrong angle of the valve guides,
Custom spring washer and valve keepers needed to be made up/sourced
Not to mention the head was not FLAT (would have been leaking from the headgasket)
The piston he supplied was incorrect. It was for a standard valved head.
I got a RRGS forged 66mm and got the valve pockets machined out. This RRGS piston was of a far greater quality than the crap piston that was part of the kit.
The cam he finally did send (extra $ paid for custom duty) was a very poor regrind of the stock cam. You can feel the "corners" of the cam lobes where it should have been round. There was no specs on this cam, hense I called it a mystery cam. Hary was unable to give me any specs on it. The engine was unable to start due to the excessive lift/duration of this cam so stock cam was used.
CDI I bought was incompatable (no refund) and took 4months to get a wiring diagram from him.
Alloy swingarm was faulty. the (new custom) chain cut through the rubber chain guard and started to cut into the alloy arm itself! (no refund or exchange)
Mikuni TM28 carb was not rejetted to suit 200cc as we had agreed
Conrod was removed without my knowledge and its cost used for shipping the head to me.
Bodykit purchased was very poorly finished with dirt trapped under the paint, also did not fit at all!
double row engine crank bearings were substituted with single row bearings with fiber cage.

The cam supplied caused the valves to hit the piston (incorrect piston)
My mechanic had to finish off the head, decompress the combustion chamber and finish the port and polish, Not to mention lap the valve seats as they had never been done. Leaking cylinder head + leaking valve seats = more power???

After talking to Hary he finally admitted to sending me a incomplete unfinished head, though to him it was perfectly acceptable to send out this rubbish.
This is what he thinks of his customers.
So quick to take the money but very slow to offer solutions to the numerous problems his "plug and play" kit caused.

Anyone who wants to try their luck and waste their $ and blow up their engines are more than welcome to buy this Indonesian Junk.

Lucky Luc also bought the same kit but canceled his order for the bigvalve head due to the poor workmanship.

Had I taken this "plug and play" kit to a mechanic and asked him to assemble and install it without numerous measurements, CC combustion chamber, bore/stroke,gasket thickness and mockup builds, I would be posting up similar threads on this forum relating to siezed engines, broken rings, pistons etc.

With all engine parts, regardless if its plug n play, you need to measure the tolerances and check they will work with other parts. Check, measure, check measure repeat!

In hindsight I should have gone with Joel's 180cc kit as he has developed his own cyl, head and piston to suit.

As for the claim hary can advise factories I take that with a pinch of salt (Or should I say a handful)
Plug n Play? More like Plug n PRAY!!!

Anyone who wants to see pics as proof are more than welcome to ask!

HAHAHAHAHAHAHAH

be honest at-least to yourself(nothing personal) there's no point to be on this thread, because i personally think its more of a marketing gimmick..

Hi Anil. I thought, I ll be a mute spectator, until now. I have a big bore 165 cc block(second bore, first one seized and replaced by Joel without much hassles), head work, high lift cam, ffe, simota air filter, clutch springs, valve springs(and stock ECU with modified CO value). In short apart from stock ECU its a fully modified setup. I have had my share of troubles and share of headaches with the modified setup. The point I want to raise is the ignorance of prospective buyers about the perils of hot roding. As a buyer you have the opinion that you plonk a bore or change the ffe and you are good to go, without any strings attached and with the same reliability. Atleast, I was of the same opinion and vouched every review(indeed every review was positive). Well I was fascinated by guys reviewing the kits the very day they plonked it and went gaga over the power bump as well as reliability. For me I took a week off and rode all the way to Bangalore from Hyderabad with the hope of getting a more powerful yet equally reliable R15. Well the honeymoon period came to an abrupt end when I found that just after 800 Kms, the piston got scored(with all due respect, I followed all the run-in guidelines and precautions). Well, all the planning and hopes went for a toss and I was left devastated. Later checked out on internet and found I was not alone. There were many such cases and the disturbing part was not a single one was documented(on xbhp). I got to know about many people reverting to stock after these seizures.
Well I contacted Joel and he gave me a replacement bore within a week and I was happy with the response. After the fix, I followed around 2600 Kms of runin with oil changes at prescribed duration. Slowly and steadily with inputs from Joel and Prateek (read Abhimanyu) I learned about the extreme precautions and other etiquette. Well with the steady engine and detailed servicing , I was hopeful of completing a Saddlesore on this setup. Confirmed with Joel and went for it. Alas, the SS attempt came to an abrupt end due to coolant temp sensor failure after initial 350 Kms of speed run. I learnt my lesson the hard way and successfully completed Saddlesore and BunBurner (http://www.xbhp.com/talkies/tourer/2...er-1500-a.html) on a borrowed bone stock R15 in my second attempt.
Well Joel suggested problems with my wiring harness for coolant temp sensor problem and I changed the wiring harness to be on the safer side a last month. As of now, the setup is stable and I do tours(NO ENDURANCE RIDES). The setup is maintenance heavy and requires detailed servicing and care. It is NO WAY equally reliable(atleast for me) and forgiving as the stock machine. YES it is more powerful than stock R15. The point I wanted to raise was informed decision of prospective buyer about hot roding and flip sides of getting the performance mods. I am sure the general anticipation is that just plonk the part and you ll have a mini rocket. But the dream ride comes to a crashing ride when something goes wrong.
I would like to request proper awareness for modified setups so that the prospective buyers take informed decision and don't regret later. Few points from my side, which a prospective buyer(R15 owner looking for mods) should know-
1) Big Bore installation pics or videos from Joel side(a long overdue). If installations are major problems, why can't we have proper steps to follow and do the thing right way,
2) The service duration is drastically reduced to 2.5 - 3 K kms. The servicing has to be detailed and more or less every servicing needs tappets adjustment,
3) Tappet adjustments have different values when compared to a stock R15. Also, tappets would go loose more often,
4) With Camshaft upgrade the kick start takes longer than normal as the decompression lever is done away with,
5) The modified setup is a bit vibey and engine mounting bolts frequent attention,
6) The FFE wool needs replacement every 7-9 months or becomes extremely loud(means -treble not bass)
7) The modified setup generates more heat and yes it needs frequent coolant top ups or a better grade coolant,
8) The modified setup needs a little more time at idling and it should be idled religiously before usual commute/ripping.

I am not here to make a point whether Race Concepts mods are good or bad. The only point I want to put is about taking an informed decision. The happy go lucky nature of all the reviews(no offense but I hate reviews of modified setup on day1 and people going gaga over reliability even without testing it thoroughly) gives a different notion altogether. As far as performance boost is concerned I have no doubts or second thoughts about the kits(duly substantiated by dyno charts from Joel). But reliability wise I ll be better off with stock setup. I have taken valuable suggestions and advices from my mentors Prateek(abhimanyu), Joel and Digislayer. And Prateek was more than willing to help me out in any of the situations. Besides, I have taken frequent help in procuring goodies from Harish and shared my share of troubles with him and others.

PS: Anil, I don't know whether you have a modified setup from RC or you had a smooth upgrade, but one thing I know that even with the most pro active care and detailed servicing, my modified setup is less reliable than a stock R15 and needs frequent attention. I have had my share of troubles and I can't simply ignore them even after quick replacement and prompt service by race concepts. On the other hand, I do enjoy the power bump.

Well the question whether it was worth? My answer would be its not an appropriate question as I was never aware of the flip sides and I couldn't take an informed decision. PERIOD

nothing personal (regarding referring you to be honest with yourself) and the personal take was for the thread not you.. and why do you pm me this?? this sums up your attitude..

Oh I am really sorry to hear this bro and thats really hard to digest a 2000USD loss, from my experience I wrote the thread and the thread points Bro Haen for advice, read it once more.

He was the one who helped me when I got stranded, not to forget the days he assisted me over the phone and chat for hours, even though I have not purchased anything from him yet. I am very much sure he is open to all when it comes to knowledge sharing.

(Just placed and order for a Denso 10 hole FI with Bro Haen and not even paid for it.)

@Mad Mik: if it is not too much to ask for the benefit of the community please do share the pictures.

Cheers,

here are some pics. I'm currently on a drilling rig with very slow internet.

Well the question whether it was worth? My answer would be its not an appropriate question as I was never aware of the flip sides and I couldn't take an informed decision. PERIOD

I almost started feeling like a fool because I spent the money on 250cc motor to obtain 25 bhp that could've been done right here on a 170cc engine. Used R15 + Mod = CBR killer, this is all I had in mind. At the same time I was wondering how a 170cc LC engine can make 25 Bhp. If you go through the thread you can see that there has been a promise (or misunderstanding) made to this member RevHard Biplab on 25Bhp, but in the subsequent post of clarification, the buck has been passed back to the member.

No Bro, you have taken the most wise decision

I will strictly advice my fellow XBHPians to see the otherside of the coin via this thread.

I have bought a duke..it has an engine nicely tuned by factory itself.

Everyday we are loosing precious young lifes on the road to mindless riding..let us not encourage or add to it.
