Changing engine

[themostestultimategenius]

Is it legal to swap the engine in my bike? Planning to put in a different engine (from a larger cc bike) instead of overhauling it. Eg. I want to put in a RVF's engine into a SP.

I know I will have lots of other mods to do to have that done. Just want to know if it's allowed. The mods can be worried about later

No it's not allowed. You are only allowed to swap another SP engine into your SP. Go search LTA website for more details.

 

If you have done enough research, you would have known that an engine transplant from another bike is a very complicated task at best, and it involves plenty of fabrication and engineering. Not that it cannot be done, but locally here? I don't think so.

If you bothered to check LTA's website, only engines made for the same vehicle are allowed to be replaced and even then it is subjected to LTA's approval. Using ur example, only another SP's engine can be fitted into a SP, not anything else. Besides, bikes are constructed with their engines in mind and fitting another type of engine into a different bike is a recipe for disaster. You'll create vibrations and heat in places that wasn't planned for when the bike was made. Not saying it can't be done, but rarely us laymen or any normal mechanic have any expertise in doing so, unless you can find an automotive engineer.

From http://www.onemotoring.com.sg/publish/onemotoring/en/lta_information_guidelines/modifications_and_vehoffences/modification_guide/modification_not_allowed.html#MainPar_0003

 

"Vehicle owners who fail to comply with the below specifications may face a maximum Court fine of $1,000 or 3 months' imprisonment upon conviction in Court."

 

"Increasing the engine capacity such as enlarging the cylinder bore of the engine may lead to premature failure of the engine and other related components. Hence, this may also adversely affect the safety and exhaust emission characteristics of the vehicle and is therefore not allowed."

"LTA allows changing of engines provided that it is of the same type as the original one. Therefore, LTA would require the following to be submitted for evaluation:

New or reconditioned engines

a) Invoice or bill of sales from the supplier of the replacement engine.

b) Certification from vehicle manufacturer or the local sole agent stating that the replacement is of the same type as the original one.

Swapping of engines

a) Swapping of engines between two registered vehicles is allowed, provided that both engines are of the same type and engine capacity.

b) After the swap, one of the vehicles must be scrapped immediately while the other must be produced for inspection at LTA. "

nice info u guys have.. cheers

[welly]

who says it cant be done??except the old folks at LTA..if u can find a whiz kid who can do the job for u,BRAVO...

power lah... RVF engine on SP... why not R1 or R6 ?

Thanks for the replies.

Because I want a small bike that can go fast. Not a big bike that people already know is fast.

Ok, let us just ASSUME it is legal. From your choice of donor bike, looks like you have not done much research at all on this topic.

 

Sure, there are many documented cases of engine swaps, but most are swapping engines of similar configurations, and not between a single cylinder 2 stroke and a V4 400cc engine...

 

Here are just some of the very basic things that probably have to be done for most engine swaps:

- new engine mounts

- align front sprocket to rear sprocket

- new wire harness

- new custom exhaust

- frame modifications

- airbox customization/modifications/fabrications

- customized radiators

- extra bracing around frame

 

And then, you may find that your stock brakes cannot make it anymore, or that the recipient bike's frame cannot stand the extra stress, or the weight distribution is totally off.

 

And a thousand and one other considerations.

 

Just buy another bike...

True true....so true....Price tag.....sure to be similar to above a class 2A bike.

 

Ohh ya forgot about the fuel tank....muz get a bigger one. The current SP one may not be enough.

 

Its better to start from scratch and build the bike up. Like Mr Arlen Ness. Anyway this guy (below) knows what he is doing.

 

In the end modded then see become RVF or CBR.

sp150 handling is not really that great.

so kinda wasted to do engine transplant unto it.

 

sumore sp150 frame is steel, not aluminium, the suspension & brakes are rubbish,

and the swing arm is dead heavy.

 

if you're talking about mito chassis, its in a totally different league.

mito is like a razor blade.

 

anyway bro, i'd like to ask how fast do you want to go on an sp150?

another sp racer wannabe lol

I know I have to do all of that. It's more of for the fun of it. I can get all the mounts manufactured for me and frame modded in the US by people I know and flown in. Cost and time isn't an issue to me

And the SP was just an example. I was planning to do it to my RS125. I've got an SP sitting around the house too. Not going to mod that. It'll be for me to ride while the Aprilia is out of commission. Don't like the SP either, which is why I rarely ride it. Could always buy another RS to ride too I'm not one who buys something for how cheap it is to maintain and run, I buy what I feel is good to ride

sound special yet weird 2 me lo

spend so much time mayb $ (maybe more ex than buy a rvf) WHY nt jus buy a class 2A bike?

 

e few reasons i can think if is u dun have class 2A licene? or u wana scare other w ur rvf engine but sp body?

 

b it illegal or legal? think save e $$ do something easier n better ba..if change le later more pro...minor pro juz repair..worst it breakdown on high speed , who knows it will b dangerous 2 u n other rds users lo. yet again unless u wana use 4 track lo...

[bleeeek]

i just would think that it will be very hard for you to hide that the sp has a rvf v4 400cc engine.. i think it will be quite obvious that the engine area would have a huge bulge and you will get stop by curious tp or rov and get fined and jailed.. so i dont think its worth it at all..

i think if you money and time is not an issue to you and you can get your american friends to help, why not just build up the bike from scratch and put a rvf engine into a similar looking sp frame and fairings..

 

its your life, your money, your time... soo good luck in whatever..

[ghost04]

do wat u want..just don get caught...anything could be possible..

One thing for sure with that mod engine,

1) inspection already fail. Due to engine number.

2) Road block confirm tioh.

3) Once tioh whole bike gone. Due to confiscated under illegal modification and straight to LTA for inspection if its from road block.

4) SP body doesnt balance the weight of the RVF engine.

 

Wat Coolman suggest is correct. Save the $ and do something easier and better. Enhancement for bike, not destruction.
