I apologize if this question has been asked before but is it possible to fit a sv1000 engine into a 650 or will it not fit? I am young and cant afford the insurance of a larger bike but would like a bit more power and wanted to see my options the 650 is plenty where i live back home in the mountains but when i moved to an area that was flatter it became a little under powered. I guess when my friend flew by me in his stock Bmw M3 at 160 i was a bit disappointed. thanks for your thoughts.

Yes it is possible - Streetfighters Magazine (a UK publication) featured one a few months before the SV Thou was launched.
I have to ask though - wouldn't you have tell your insurance company that you have a larger engine that standard ? So is there any real difference between this option & buying a bigger bike ?

Changing the motor is no major problem but I would be seriously thinking about the suspension and brakes as well if you intend riding at 160mph,plus as Vox says there is the insurance issue. Is it worth the hassle? would it not be easier to just change bikes?buying something that is designed to do these speeds

You'd do better buying an IL4 600 sports bike!!!!

That was my initial thought as well - although I would possibly look at the Gixxer 750 as well :D

Dosnt seem worth it, and you'd have to declare the change to your insurance company anyway (else your insurance is invalid).
I was thinking about this the other day though; a 1000cc curvy, anyone?

[EDIT] I'm expecting people to say "yea, 1000cc curvy...its a tl1000s..." :oops:
Yeah 1000cc curvey is a TLS :lol:

I'm pretty sure that in the UK, insuring an sv650 with a 1000cc engine transplant would cost more to insure than an sv1000. The suspension and everything else would be worse too.

I see what you guy are saying i mighty just look for a sv1000 i was more wanting to see the options and i love the seating position and feel of the sv better than the gixers is partially why.

Why is it everyone seems to consider the 750's instead of the 600's, coming from an sv650? People don't seem to realise that a 600 is a HELL of a lot quicker than the sv650...common misconception that people think it isn't... :?

Only if you rev the ******** off em. You've got to be getting over 10k to get significantly more power from a 600. The 750 has more lower down. That is why the sv is better than an SS600 :D

Pers'nally I reckon that the 750 is a better street bike than either a 600 or thou, and I assume that anyone upgrading from another reasonable bike (ie, SV) will be comfortable with it so I'd recommend it over the 600s. Not that SV owners will be dissapointed with a 600, not at all, but the 750 is a better choice as far as I'm concerned.
As for the thou engine in an SV... It's been done, but it means major frame surgery and even then it still doesn't work as well as a TL or SV thou. No reason to do it other than that it's a hell of a project, many reasons not to.

putting the 1k motor in a 650 frame is a lot of work!
engine mount points are different and engine size means some of the frame has to be chopped out.
get a tls!
soooo much fun! :twisted: :twisted: :twisted: :twisted:

Trust me mines not :wink: I can understand why some people dont like the IL4 but if you get the right one boy is it fun.
I prefer mine to the SV, but they do different things and behave in different ways, both have advantages and disadvantages. On cacky wet days I'd rather have the SV, the power delivery is much easier to cope with on a wet slippy road. But on a dry day give me the GSXR every time.

I keep on getting pulled to the idea of a 600 (CBR600 or R6 - is it CRB or CBF... or CBR600F...), but then one pulls up to me at the traffic lights and I listen to the diff in engine note (and I'm only on a standard pipe) and I just couldn't do it. Sure they sound nice, but a twin is just in a diff class.
I want either an SV1000 or Duke 748 next. As I commute a lot I guess the SV will be the choice...

You can commute on a Duke, dont let people who dont know any better fool you. The service interval on Liz's 749 is bigger than the SV is.
I'm not saying its better an IL4 is just different, the ride is different the sound is different. I'm guess I'm lucky I'm able to appreciate both :D

Yep, but it's a horrible shame to submit such a nice bike to the battering/borderline abuse/neglect that commuters tend to. I'd feel sick to my heart if I treated one the way I do my SV...
so how about goin for a big bore kit? i`ve heard you might have to up grade the bottom end but if you wanna keep the same bike and have more power it`ll probaly be cheaper n easier than shoe horning a thou lump

Yeah but its a bike its made for riding not polishing...
To be fair Liz has kept her SV and thats being used for a winter hack and so that the duke is subjected to winter roads, but once the spring comes the Duke will be used for commuting on.

If you are going to go down that route, then you will need to upgrade front and rear suspension as well - if you can afford to do that, then it could be a better option than hacking the frame to put a 1000 lump in
It would still be cheaper to buy an SV1000 though.

Nah, it's a Duke, it's made for riding but also lusting after :)

I've been thinking about getting my 650 bored out to 700cc, any more than that and it starts getting very expensive (£1500+). A 750cc SV would be nice though.

I think Northy summed this up nicely a while back. By all means tune an SV engine, but accept that it is not a smart economic way to go. Upgrading bikes rarely makes financial sense as it won't add to the resale value.
If you just want cheap power sell the SV and buy a bike with a more powerful motor. If you want to keep the SV and get more out of the engine then some good posts have been made on swapping cams over, using different air filters, different exhausts, big bore kits and re-jetting the carbs to suit, but after all that work you're going to be about 20bhp down on a SS600, the motor may not be as reliable (Big bore kits are an on-going discussion but some people seem to have good reliable 700cc SV race bikes), and upgrading the suspension would probably have made you quicker everywhere other than a straight line.

P.S You'd probably want to tell the insurance company about all that work too, and modified bikes are not always the easiest things to insure :(
