That's a stock exhaust of FZ16

Hmm...quite surprising; but how about the RTO & registration part or did you just skip for time being? Or are you saying that the Chinese manufacturer engraves you with an existing engine number that you send? I couldn't get & hence the question.

To gain more on the mid range right?

Agreed strongly

@Lavs sir - Sorry to bug you with so many questions because, like you, I too have a hand made Yamaha Rx but with 3 combination of 135 4S cylinder, 5S gearbox with looks of Rx100. I took about 8 months & under went a hell of agony. I'm sure you'll know what I mean & hence I've so many questions as how you tackled so much issues.

But it was good that you started a new thread. Thanks.

yes, i think he means the new engine has the same engine number engraved as that of his stock engine. if that can be done then one can easily avoid the hassles of getting the registration changed.Sounds good to me. by the way, don't we have people here who engrave numbers on to the engine. if someone changes the whole block for a restoration, how can the original engine number be engraved on to the new block. do we have a way to do that in india yet? we all have seen many restoration projects here on TBHP. people do change most of the engine parts including the block right?

Well, to give you a real picture, the RC book says, engine capacity 153cc & 14hp motor, while in reality its 250cc & 26hp motor. Since the Govt babus have a "chaltha hai" attitude, we don't need to worry much on this.

This is done at lathes who have the tools for engraving. They can do it on the chassis as well as the engine too. This is how I got it done. Anyway, mine was legal & I'd a note from the YMIS dealer, so the guy at the lathe charged me nominally & didn't ask any questions. Otherwise, this is little illegal

I think on another thread (Dustoms?) somebody mentioned the govt. is planning on bringing in a section under which custom vehicles can be registered.

One can only hope..

i was asking for the legal way. just in case someone loses the engravings due to an accident or something. so its not much difficult as i thought it to be. one can easily convert a 350 into a 500 easily if money is not an issue then.

@Lavs: can you post a few close-in pics of the radiator and the engine mounts. and how is your battery responding to the additional load. or have you changed the stock battery too?

Great job. Please do keep us updated.

Engine and accessories means gearbox etc too?

Hi everybody,

The exhaust is not stock and is free flow type. Only it looks like a stock. And it does'nt make too much sound. For long route driving you need a relatively silent vehicle. The tail pipe is 33mm shining peice of Stainless Steel.

@ aargee - Bigger the rear sprocket - you get reduced top speed, but increased power/torque. I have smaller rear sprocket and hence better top speed (as the engine is capable of generating the torque). This bike that I bought in white colour is no more available and has limited edition written on it. So it is different.
You are into some serious modifications - doing it yourself or dependent on mechanics?

Rear Disc will come. I am not happy with the way people fix rear disc. Will take my time to design and implement with whatever is available in the market.

@ jkdas - Engine and gearbox are a integral unit. Everything including the electronics.

Well, I did the legal way; I bought a new crankcasing from YMIS & hence I obviously got a bill. They usually charge about Rs 350 for embossing the engine number, since we'd a good rapport, they asked me to take the bill & ID proof to a certain shop where they have a tie up & thus I got it done legally.

This is the tool to get the embossing done. Apart from this, there're machines, most shops in India rely upon this type of tool.

Incase of accidents, things are much simpler as the A.S.S would take care of those things.

Yes, but the RC would state something else as I posted earlier.

Oh!!! quite interesting; some insights on how this was constructed will be very helpful.

I hate con mechanics & I really want to thank the con mechanics who drove me nuts due to which I learned things all of my own. Except the crankcasing consisting of gearbox, crankshaft & clutch assy, I'd assembled every bolt & nut by myself.

Since you're doing most of the mods by yourself, you may want to consider Ninja's petal disc brake setup.

Now this is something very very interesting.i have been looking for this kind of upgrade for my cbz.there is a good mech here who can get this work done but the problem has been getting an engine down.How did you get about importing this engine and what has been the expenditure on this?

Also what all engines are available from the company you have imported this from?
availbility of spares in case the engine goes kaput owing to chinese build quality? hope this engine turns out to be a reliable one.We'll have a good solution to these stupid manufacturers who have been offering us 100-150 cc's forever.

Terrific work Lavs.

Cost of the engine and the means to import one would be extremely helpful.

Kindly PM me if you do not want to share this openly on the forum.

Cheers,

Jay

These are just two; I googled from this post.

I guess once you buy the engine, you're on your own. But there's always a solution - The great Indian juggad

Well, ^^^ doesn't sound nice. Its not the fault of manufacturer as they're controlled by customers. Next time, when you're on road, keep a tab on how many Splendor, Shine would you find compared to ZMA/R, P220 (I'm not deliberately Kwacker here). Most of our people want 0-100 under 5 seconds & 100 Kmpl that are inversely proportional for now.

Regarding the exhaust - I just removed all the restrictions like Catcon, Pipe in Pipe construction with a regular bigger pipe. Simplest way I could manage was minimum restrictions and maximum volume inside to store gases. Any pipes for interconnecting compartments inside the exhaust to be made adequate for minimum restrictions. I used a electric hand cutter to cut open the exhaust neatly. Did the cleaning inside and got the thing neatly MIG welded.

One thing you need to consider in all modifications is that any welding being done has to be MIG as normal electric welding overheats the metal and makes it hard and may result in cracking because of vibrations. Electric welding if done shud be using inverter based high frequency electric welding machines and try to use SS welding rod. SS and MS join very well.

One principle that I adopted from the very begining was stay away from the big industry modification names, find a cost effective way to find the best solution for any problem faced.

@ aargee - You project - I understand that you are using cylinder from a 135cc 4 Stroke bike. But what is the internal diameter of the new cylnder and what was the dia of the original cylinder? Which piston are you using and how will you ensure that the compression stays within limits?

Excellent job. Hope YAMAHA takes a leaf out of your book and gives the FZ the engine it deserves

The chassis can take much more than the normal run-of-the-mill 150cc that it sports, blame it on the mileage fanaticism. Unfortunately, its the mileage that brings in most of the FZ sales

@Lavs - There's no rocket science or breaking head in my build; I simply used the 135 (or rather 132cc) cylinder & head. No engineering & kept it simple.
