Convert Shadow 400 to 750?

[khoonkeat]

Being riding Shadow 400 for 2 years now. Feel like changing the engine to 750 if that is possible. Any advise?

 

Thanks.

Interesting?

Same model. Looks like same chassis & front suspension.

Looks like it'll fit.

 

I'd like to know too.

[gohjohan]

I didn't change the engine,Shiraz

 

ok, my opinion, from a 2000 Yamaha Dragstar to a 2004 Shadow 750 Aero, power difference is indeed not that noticable 'cos the hp is only more by at least 10-15. Btw, both are shaft driven bikes, so some hp loss is expected, but the smoothness is still there.

Yo Johan....

 

u are saying that the increase HP from 400 to 750 not that much difference...

 

how does 250cc = 10-15 hp only..... and here i am trying to get my class 2 to change to a 750 ACE. The 400 cc is definitely very much under powered.....

 

My wife was saying that my x9 felt faster.....

 

I know its not about the speed and all....but its good to have a bit of a grunt to get out of sticky situations.....

 

mebbe have to aim for the 1100 cc already.

 

but anyone knows who does or have done a engine conversion from 400 to 750cc??

 

WOuld be quite keen to know the outcome....

 

at least u ay on roadtax....

 

hahha

Both bikes are shaft driven, so the power loss is there. The 750 is better with torque, so uphill is a lot better.

 

The X9 is auto so the pick up is going to be faster 'cos all you have to do is to floor it.

Yes. It is possible but do be aware that you have to obtain approval prior to inspection and the process could be quite tedious and time consuming. Do forward your query to LTA at Sin Ming.

eeerr.... i dun think we wanna do legit rite...

[khoonkeat]

Yes, not legit mod since it is the same chassis... A friend told me that a new engine would only cost some $1k plus and with workmanship thrown in, $2.5k max. I would then have a "new" bike and save the world too...

[adriel]

think u better budget for more..... engine transplant so many areas can go wrong......

 

but u are right... if u keep for another 10 years...saving might be worth it.....

wanna extend the COE for what bro? scrap the bike la... u've already acheived the ultimate what.. but seriously, do u still ride the shadow?

[sgstarrider]

goh jo-han, wen u said "just floor it" macam driving pulak.

 

shouldn't it be ' just squeeze it'? 2wheelers use throttle not pedal ley.

 

happy holidays all riders. Yahoooooooooo

[maniahk]

hmm.. so actualli shadow750 n 400 not much of a difference huh.. rather disheartening.. haha.. goh johan u mentioned dat uphill is alot easier w 750.. wad abt w pillion? on my drag it feels quite lively when i'm riding alone, but once i pick up a pillion i can feel e slow-down.. of coz w pillion of coz heavier la.. but juz wanna check if e 750 dun feel much difference w or w/o pillion..

 

n i read 750 max spd abt 150 onli? haha..

[shiraz]

150 good already leh... actually it's like this, sportsbikes always discuss top speed and all right.. ok for them bacause they can mantain at that speed for awhile.

 

for cruisers, 130 or 140 is fast enough because at that posture, u're being like a sail in the wind so u'll be pushed backwards and using all your might to hold onto the handlebars.

haha true.. but w a windshield can substantially reduce e problem rite? haha.. juz wondering how does a shadow 750 compare to a magna 750? hee..

 

n y did dey actualli put a speed limiter on shadow anw?

hmm wad abt low end power? my dragstar feels choky sometimes when moving off from stop if i dun open enuff throttle.. but i dun realli like to open big throttle esp at lower end speeds..

$1k plus for a new 750cc engine? you've got to be kidding??

Yes, I do. It's the best all-round bike for me so far. Easy on the fuel consumption, handles well in the traffic jams and also is alright for touring.

All the same, in the name of acceleration

let's clear something 1st. Not much difference in power, doesn't mean it's negligeable. Hence going uphill, even with pillion, still can make it up without any downshifting of gears.

 

Actually my Shadow 750 can go faster than 150 km/h, but I dare not risk it when there's a pillion and also the engine feels hot. I know we were talking about going faster to cool the engine, but on a hot day like that, it's not worth pushing it that fast.

 

 

hmm wad abt low end power? my dragstar feels choky sometimes when moving off from stop if i dun open enuff throttle.. but i dun realli like to open big throttle esp at lower end speeds...

 

yeah, for the Dragstar, it won't work to your satifaction of finding the strong horsepower pull at the lower end. The power seem to come from the 3rd gear and onwards.
