Is the 180cc Big bore modded on the existing block or on a new block ?

@Harish - Please keep the discussions offline. You have a build experience at your own level, lets not dilute the efforts that we put in here.
Every product or component that has been developed inhouse is what we offer and not some chinese or indonesian kit.

We have now developed the following parts for the FZ and it looks very interesting when you throttle hard,
180cc bigbore kit with hard sleeve and racing semi forged piston
custom grind camshaft which will help bump the power band much higher into the rev range. Comes with and without the decomp lever. We prefer the non-decomp version for improved rocker life at high revs.
High revving CDI module with 8 switchable maps. On the fly adjustments can be made. Plug and play. Revs till 11500rpm.
All these will be available shortly. The bigbore should be up in 2 weeks.

its orion yamaha koramangala bangalore...i guess they have the device to change the CO settings...
as per mechanic(local mechanic not yamaha mechanic) he said that the plug and gapping is fine only..we also checked the airfilter..no issues.. i just replaced the stock ecu and its working just fine..cold start..after 7 hour period start..no issues..i am almost convinced that its something to do with ecu mapping..i hope joel can fix this..i must also remeber to tell yamaha ppl not to touch my idle speed or timings or any other engine settings because joel's ecu should be taking care of these things already(as per my understanding)

Hi, i'm from Indonesia which sends the ol' veteran Lucky Luke the parts, judging after yamaha servicing thing.. it could be your spark plug.. check the electrode clearance.. if you already bore it up or changing ECU or cam it could be leaning out.. but i suspect the plug clearance is too tight.. causing it to jerking or burping maybe.. it's already happening on several cases here.. maybe some guy changes the CO adjustment on your bike ?


yes it could be.. but if the bike before serviced at yamaha running well then it must be other problem.. or some guy changes the CO setting.. (assuming the Yamaha Service Center has the FI Diagnostic Tool)

It running lean... the map needs adjustment....

i checked the plug..its okay..clean..and dusty silvery in color..checked my air filter..pretty clean and dust free.. still the issue persisted...
THEN i changed the ecu with my stock ecu..started her up with out ANY hassles..single start..no jerks..no irratic rpm needle behaviour...this means that some thing m,ust be issue with the ecu only....i started experiancing this after yamaha servicing..they do somethng to the timings or idle or something which messes with the race concepts ecu mapping...

Yes, please open a thread and share the Knowledge. It would really great if you update a few snaps in every stage of your modd process.

@lucky luke

hey ,i have heard about automotive spare shop from Indonesia
he is offering lottsss of performance mods to FZ and R15 n they r very much reliable .
dont know about the price though so cant compare it with joel

@luke
please PM me about the price he quoted and what al parts u ordered from him ?

but i wonder what wil be the service backup if any part is gone ? wont it be an issue getting the same part all away from Indonesia

Dear HarishK,
I shall reply briefly in order to avoid this thread going off the topic too much (since it is about Race Concepts).

FYI: Yes, am going for the whole thing, from carb. to exhaust. Will start a thread about that when done. This will as objective as possible, and purely informative, as I have no financial interest in this Indonesian supplier.

Effectively, there seem to be, from what information I can collect on the Internet, nobody in India besides Joel Joseph who can study and undertake such big, deep mods on performance bikes.

Sir, I too agree with you to a certain extent,

But Indonesian biking scenario is completely different from India, you have to admit that.

Coz, in Indonesia, we have good/reliable workstations where they modify Low capacity bikes and sell it out just like a new bike and they even warrant their modified bikes to a greater extend, including after sales service etc.

But in India, R15 was the 1st mass production bike to have an LC Engine, and even Yamaha service guys are not well aware of servicing an R15. Owners themselves are very much scared to do R&D with their engine, only Joel has taken the task of testing these Kits from south east and comeup with the best combination and the right product upgrade.

I too admit, I did Joel my bike and was not satisfied with the Piston/Rings quality, so I went for a Shark Yamaha/Honda R Type Piston,

its a fact that Shark Trademark bore/piston are the best available in entire South east, but costly too. (You can ask any LC Modifier from South East) But the Shark User manual says, there is no warranty on the product unless if its being fitted by a authorized workstation, which is no where in India.

Right below you can find my Facebook link and you can find one of the Svc guy from automotivespartsshop.com listed in my friends list, He himself recommends not to plonk the next size block until you convert the total setup to fit the oversize piston, I mean Porting, Gasket Clearance etc.

Now you suggest me and place here in India, where to get all these done under a single roof, with reliability and support?

I maybe banned from xbhp forums for saying that, but this seems to be a real problem with this otherwise nice and knowledgeable person who is Joel Joseph! I exchanged numerous mails with him, to which he replied to one question on five on the average. I asked him a month ago if he would consider making a 200cc. kit for me: not even got a reply...!

So: I have ordered my "bore up" kit (200cc.) from automotivespartsshop.com, Mr. Haryono Adigunawan, and it's on the way after one week. All clients definitely confirm both quality of the materials delivered (high materials specs and tolerances) and of the technical assistance from this person. Trouble, being on this Indian forum: this person is in Indonesia.

Please let me be well understood: after twenty years in South-East Asia, I have very high consideration and esteem for you, people, and for your great country and culture, but there seem to be, generally speaking, some drawbacks in the way business is done there, as well as the care given to production (my FZ-16 clearly shows that!). Definitely has to be addressed.

Respectfully to all
Luc.

talked with him, he said he will get back to me after reaching bangalore.

yups waiting for his response.

^^^ My experience with Joel has always been straight forward.... Be patient, if he has said that he will take care of it, he will...

Don't worry he would take care...

He is a wise guy !
