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...

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

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)

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)

@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.

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

joel will provide a new block along with piston and piston rings.

Joel bro, may I get a reply on my this post?
You said "if there is a market, I don't mind making one batch of P180 exhausts...".

So, don't you see the market as yet?

Joel,
With all due respect for you competence, I must say that this remark is saddening.

Let's just understand the image of chiness products. why Indian refrian from using chiness products. They have flooded the market with economically cheap products, but they are not reliable and that's what Joel is pointing out.

It's a common knowledge here, & i understand the fact that you have different experience, but that's how it is here brother.

Oooh wait lets not jump the gun!the man just said what he sells isn't the Chinese or Indonesian kits which are available in the market.

peace

Most chinese kits are copies of a larger piston shoved into a large sleeve, with the lowest price tag and to flood the market. With no engineering or stress analysis.
Indonesian kits are again, blocks picked from the Yamaha factory, or with copies made in china, then shoved with an aftermarket chinese piston. Most kits sold as "FORGED" is not forged. They are forged look-alikes and are sold at a premium.
Its come to a point that a common man, cant figure out whats real and whats not.
On our FZ kits, we ensured, we modelled a piston first, ran them, analysed and then its now mass produced. With the right valve pockets, compression height and zero trimming over stock. The same applies to the P220 kit as well. The P220 bigbore kit is the first of its kind in the world by race concepts. Again, the prototype engines are already running on a few xbhpians bikes. The results have been very interesting.
Just an insight again.
An FZ bigbore kit sells for over 200USD - Indonesian/chinese kit - with a make-shift piston from an aftermarket chinse brand and an oversize sleeve. Our kit just costs a lot lesser than this, with a fully inhouse developed package. The block is custom made to be 180cc and not a bored out yamaha block. With more material around the sleeve and ensuring sure shot reliability as well.

Joel,
How many mails have we exchanged and how many replies did I get from you to precise, numbered questions? How long does it take you to reply to mails....? Etc...etc...!

I went to you in full confidence that you would deliver the best stuff and with my mind set that you would be the one to who I shall order all the "goodies" I was wishing for my bike, but in fact you have let me down. You said this or that will be ready in so many days, etc....and then nothing!

So: don't be surprised that one gets a bit fed up and finally turns his eyes to another supplier. You are not the only one in the world, Joel!

Now, let me tell you about about this Chinese thing: yes, their home market is so huge that they can produce very cheap stuff, and if asked to do it real cheap-cheap, they will! Then, who floods the International markets with these cheapos: the people who place the order! In your country, that will be Indian people.

I have a Hoa-Jiang motorbike, 20,000 km. on Vietnam roads: only repair been an aft wheel bearing! Of course, it was not the cheapest bike on the market, but I got what I had paid for. I wish the quality of my much more expensive India made Yamaha was up to the plate with this Chinese bike! It is, sad to say, miles behind: leaking valve seal that char-coaled the engine, fork bearing that keeps causing problems, and lacks of paint that is causing rust in many places. This with 2,000km. on the odometer...!

Presently, China is the only country in the world together with Russia that has inhabited satellite launching capability, their medicine (in some fields, like the cancer that was "inoperable" in France for one of my friends) is so advanced that they are selling it over US and EU, their engineering level in many fields is world acclaimed (think Three Gorges, Tibet railway...just like Indians in IT), and I can personally assure you that they beat a lot of pretended top school alumni! Besides that, we alas have to say that the corruption there is such that the country suffers a very bad image on many other respects.

About the kits provided by the supplier to who I have now ordered, considering your deficiency: the piston is made by TDR racing Company, in Indonesia, whose results in races I invite you to have a look at. This is a lightweight (real) semi-forged piston. The sleeve, also Indonesian, is effectively inserted in a (genuine) Yamaha part, and it has shown that there was plenty enough metal left around that high quality sleeve so that there is no need to cast a new cylinder. Valve seats (gamma bronze) are inserted using liquid nitrogen and not pressed. I was feeling like doing the research for the porting, including Computational Fluid Dynamics (basic), but had no time for this fun and left it to this very competent Indonesian person (don't worry: he knows his job, and his bikes too wins races!). The Yamaha ports are actually very well designed and swirl is no problem with them, as you know. Just adapting to the new capacity/ valves. Etc...etc...

I have, Joel, in any mail, posts, always shown highest respect to you, and to your country. You post here-above shows, in my eyes, disrespect for two countries, un-founded suspicions (just non-documented affirmations) against a person you do not know, and generally speaking a defensive attitude which you should not need: just do your job as you have to, both technically and commercially, like this person does, and everybody will have what he deserves.

Unless not allowed by the moderators, since this is a forum about Indian bikes (and accessories), I intend to give a full report here, in all honesty having NO commercial relation or interest in this supplier, and will report any success, incident, or total failure if it happens. I then hope that you will be a gentleman and kindly sell me your parts as replacement.

Regards

^Let me explain. Please, understand the point of view from this country is very different than what you think it is.
Now, my kits are developed inhouse and we have our own timelines. Also with our racing season running in parallel and with many other things alongside. Its hard to explain how the last 6 months has been to us.
That said, we will never push any work just to finish it off, in a hurry.
I have been guaging the market and seen the stuffs around. All the kits that are being sold, like I said are make-shift arrangements with an aftermarket brand piston and using the standard Yamaha block. Whats offensive about this part? A large piston with opposing valve pockets, just milled to the off-set valve pocket arrangement of the FZ as a make-shift. There was no offense meant in any way to any country.
And please note that your posts depict some sort of frustration towards Indians. I dont know which Indian did harm to you, or if thats a state of mind!
You have a project with your FZ, please go ahead and do it. I'm sure, you have your way of working. ANy help, we will help you. Please get back, if you need help in any form from my end. I have responded to all your mails as well. Maybe not in length to the extent of your mails, but in short detail.
Right here in India, we have enough resources to create automobile exotics. Its just sad that all the good stuffs leave the country and we get nothing. We have even built cylinder heads with some exotic metal valve seats and my race engines, run that. Its just that here, we lack the exposure and availability like the other asian countries. Labour is also getting too pricey here.
We have no disrespect for your country or talent. So please go ahead with your plans. All the best!

Joel

really love this part !.. any kind of input is welcome
