Query Approved

Thanks Sunny for approving this thread.

People please provide your valuable comments ....

Never tried of updating this in papers

But we have done - this in yamaha rx100 - we changed the rx100 engine to that of suzuki shogun

thunder: i'm guessing the cops never catch on right?

before the xbhp server crash, there was a thread started by rajkumar about mating an imported NSR150 2 stroke engine to a pulsar frame in chennai. now the thing is that the cops are going to get pretty suspicious when they hear and see an odd looking pulsar

another instance (if you can call it an engine swap) would probably be venu/joel's v-twin fiero.

till now i'm not sure if an engine swap is legal but i keep hearing it isn't. it's just a matter of making sure the cops don't catch on i'm guessing. what kind of swap do you have in mind?

Just speaking of a normal engine swap between 350cc to 500cc bullet engine.
Both would sound almost same the only issue is the engine number would not match that of the original bike ?

I heard that the process for legalizing this is very very lengthy from an RTO Agent.
dunno if any other alternative could be possible.

I kinda knew this thread wont have many replies....
firstly any mods to a stock bike makes it lose the road legal status.... a list of all changes need be registered with the RTO, along with the reason for the change.

The last I read there was a clause that the revised setup needs to be monitored and checked BY the RTO for being 'compliant' .... that is a BIG pain area...

Thats all i know off!

a bike with any sort of mods not been registered with the RTO is ilegal....and registeration is almost impossible now...it was possible first...(ie.those desel bullets)....

the best and probably only option would be to get the engine swapped and to keep a low profile avoide the cops...

Exactly... coz I think its not worth going through the mess with RTO ppl.... even getting a NOC for changing state is a BIG thing... so keep a low profile with police ppl and be un-noticed all the time in traffic.... you will save lots of pain and money....
Even if you get caught by chance.... bribing them with 100-200rs would be affordable rather then getting the modified thing registered. If the bike has heavy cosmetic mods then I guess you will end up in soup many times... but engine mods would be overseen most of the times.

EDIT: But in times of accidents/big crashes the bikes are inspected (either for issues, or for insurance purposes of the other vehicles involved in the crash), thats the only time you might get into issues.....

I seriously doubt, if they can indeed catch a different engine bike, in such heavy crowd... Anyhow, not all Pulsars sound same.. some sound space-ship kinda, some like Rajdoot, lol, (different version, different sound)

Just a mess-up with exhaust, troubled engine-oil/ RPM setting/ something else I dunno, and you can produce different eng(ine)tone..

Nobody bothers to match engine/ frame number, usually they do just number plate/ license checking..

It can only screw up, if you meet an accident.. or, if you are in real bad-luck with a probability of 1 in a million.

For this kinda of a mod for a Bullet you dont have to ask the questions cause no one really notices the difference between a 350 and 500 the only problem you may face is when you sell the bike but again if you find a entusiast there would be no problems. till the time it looks stock or say normal its fine i suppose in our INDIAN system

regarding engine numbers on the bullet talk to your mechanic they would be able to wipe off the old one from the crank case and punch in the new one and after that get it buffed and there you go no problems at all

RTO worries

hah dont even bother... even getting a license to ride your bike is a big pain if you do it without any bribing (for faster processing), and yes NOC is a even bigger headache

and about engine swap mods ? forget it.... those RTO fellas will never get your enthusiasm of experimenting and seeemply reject it.

best is not to "show" that you're different.

only issue i can see is if the vehicle meets with an accident. if its a self inflicted accident.. dont even think of claiming insurance. that would lead to trouble

and yeah it MIGHT fail PUC tests since there's a limit of emission norms for 100-150cc or 200c+ etc etc ranges.

bachke rahiyo galiyon ke raston sey satak lo

actually its not about the experimenting thing that the RTO is worried about if you want to go for mods or build a bike and stuff there is a procedure where you can register your bike but there is a certain procedure for the same. these issues are because of the saftey reason. cause a stock frame of the bike may not be able to handel the stress by all the Torque or the BHP being produced by the engine. or the engine may not be able to houl the long frame or other stuff that you have atached to your bike. so this basically makes the bike unsafe for the road and thats where this regsitration thing jumps in. all the custom bullet cruisers on the road are illeagal i hope you all know that with those long wheel bases extended front ends and stuff.

now the question is how come the people do it abroad.

just for instance i know a lil bit about the procedure in the UK

if you mod a bike or a car, you have to put it through with a MOT. this is a test that checks that if the car is raod relaiable. and if you pass it then you insure the vehicle and you are all set.

see there is a procedure but sad thing is that the procedure that we have is not a easy one cause the rules being followed are ancient.

aye sir ! there certainly are rules.. but who will bother to do it (for the hassle in return) ? the hassles make the rules literally non-existent.
arent the RTO's way tooo much loaded with work :| ? RTO guys somehow never seem humane when i had taken my cbz-x to ahmedabad i wanted to pay the road tax, it took me while asking people where the heck do i pay the road tax ... and the damned line was so long and moving inch by inch i was like "chuck it"... i was lucky that i didnt get caught in the two months i rode my bike there.

engine swapping might be the least of cases a RTO will ever get.. and seeing the enthu those guys have i doubt they would even be helpful in the tiniest bit \

It is very illegal to drive a bike that is not registered, hence no insurance either!
The RTO does have a provision to Register "Modified" Vehicles, infact it is a requirement, even when the mods are not so radical as swapping an engine. The bike has to pass and be certified by the respective authorities for mandatory requirements such as safety, pollution etc. This can be a time consuming and expensive affair for some. Most modified bikes wont pass all these tests as they can be quite badly put together with the intention to save money.
