my project- SVFR

[vzzzbuxt]

well due to a few bits lying around, and the fact i do love the sv 650 engine, but crave more 'flick-a-bility' in a road going frame id like to use this thread to kick off my new build and follow it through.

ill post any shortcomings i have and pics of progress as i go along for those interested.

initial plan;-
VFR400 NC30 frame (retaining original geometry) and rear single sided swingarm, excentric hub remachined and spaced to fun with a 5 spoke vfr750 17" rear wheel for sticker rubber options...:batman:

ducati 996 USD fully adjustable front end with 320mm discs and brembo goldline calipers

bodywork?- not a clue at this stage.

engine mods-none right now other than cone air filters due to space/size. and exhaust re-rerouting due to frame design. once its properly all in and together then i may go for engine tuning...

no actual pics yet- for starters the rear hub is away being remachined for vfr750 wheel fitment, and im waiting of a few bits for the ducati front end.

...im also waiting on the actual doner bike for the engine (thanks for bearing with me here paul- all this expenditure is getting me lined up for divorce!)


this is a initial pic of a guy's bike over in the states who had a play back in 2006 with the idea but got rediculeously sidetracked ever since.. but you get me drift-:smt040

and yes i know the frame is gonna need a lot of modifications for mounting point fitments, but thankfully i have a enthusastic local machining guy thats always up for a challenge to give me a hand.

I'm not leaving my Duke unattended when you're around then Mister! :mrgreen:

Duke front end, single sided swing arm, v twin. Got to be good. :D

Good luck. will watch this project with interest.

[DarrenSV650S]

Very interesting. Should be great when it's done

[yorkie_chris]

Cool. Enjoy.

[Mr Speirs]

Looks like a promising project. Looks good even now. Shall keep my eye on this. Good Luck

[amnesia]

Is it done yet?

[maviczap]

Dat single sided swingarm is going to look the business, very jelous & interested at the same time.
Keep us updated

[xXBADGERXx]

Machining parts for the frame won`t be a problem and getting them welded on as well will be quite easy , just make sure that the frame won`t need to go in an Oven afterwards . There is some form of heat problem that can arise from welding certain types of Aluminium . Look forward to this dude :)

[Thingus]

Nice one, kinda brave. Are you gonna ride it or go crufts and show it off?
Best of luck!

[xXBADGERXx]

Ohhhhh Ohhhhhhh Ohhhhhhhhhh RGV250 Bodywork ? With a bit of sideways expanding it could look SAWEEEET!!!!

[Dangerous Dave]

Good luck with the build, although I will say that the SV frame is a great frame already!

[vzzzbuxt]

Cheers guys, I'm open minded about downfalls and possible changes during the build. But that as they say is a budge to cross when I finally come to it.....

[thedonal]

Might it be less work getting a VFR swingarm to fit a curvy frame, than to get the VFR frame to fit an SV engine?

[Jester666]

Here is the svrider.com thread (http://forum.svrider.com/showthread.php?t=69736) on doing the single sided swinger conversion for the curvy.

hmm,, you know its your bike thats going under the angle grinder!!!! LOL


i may well look at going down the SV modding route if i get to stuck with shoe-horning the SV motor in the VFR400 frame. but only as a last resort

:batman:

[markmoto]

that would be a great tool but looks like alot of work, goodluck fella

[xXBADGERXx]

Engineering wise it isn`t that much hard work if you have access to a Lathe/Milling Machine and a good Welder , the Devil will be in the detail and I can foresee a broken man in 2 years time because he just can`t find the correct shaped nut for a fairing , when everyone else can see a perfect bike :)

[Ceebl]

Wow! This looks like an awesome project, very interested on watchin how this works out 4 u!!

Good luck!

[dual-power sv]

a word of forewarning. i have swapped quite a few engines from frame to frame, and the main problem we've always encountered, isnt making the engine physically fit, but getting the sprocket from the engine to wheel to line up. in some cases we've been lucky and its been very easy to fix sometimes not we've not been so lucky.

lets just hope your lucky.

and loooks like its going to be a head turner, definatly keeping an eye on this.

luck is upon us the vfr400 and sv650 have a lot of common traits, ie the rear shock is the same place on both bikes and the exhaust downpipe exits the same side of the shock on both so only needs minor modification.

the sv sprocket and the vfr400 rear on the swingarm only require a minimal spacer which isnt required as the vfr750 rear wheel im fitting will counter the offset to within approx 1mm


the main work is engine mounting points on vfr frame, and then the under tank work (assuming i keep the vfr tank?!?) to accommodate anykind of pod filters/airbox and the higher sitting carbs- i may loose some fuel capacity or i may just go down the route of a one-off tank getting made, that wuld mean i can even increase capacity, or keep in style with whatever fairing/bodywork i choose to run with, but that for later

[DarrenSV650S]

If you don't mind me asking, roughly how much do you reckon this project will set you back?

[markmoto]

i think this would be a wicked bike if you could keep it looking as vfr400 as possible

yes i'd say your very lucky, we've spent hours trying to figure this problem out on some bikes

[vzzzbuxt]

my thoughts exactly, although vfr chassis, the bodywork may stretch towards the newer and slightly slicker looking rfv400!! bodywork will get toyed with later after i have past the rolling chassis+fitted and running engine ( so i can test ride it on an unpublic road first)


If you don't mind me asking, roughly how much do you reckon this project will set you back?

honestly? - enough to cover a return to a single life!!!:batman:

but seriously, ...:rolleyes:

ducati 996 complete front end, vfr400 frame, rear swingarm and bits, the vfr750 wheel. sv650 engine+carbs etc..
machining work to fit modify the front end and rear wheel to fit to vfr400 chassis.

£700-ish so far, i imagine same again to having a 'running' bike, and probably times that total by 2/3/4 to get it to me considering it 'technically' finished.:smt040

[vzzzbuxt]

i initially thought of a sv1000 engine but the rear cylinder is the opposide way round so straight away heavy mods to frame, complete relocation of rear shock etc...

the sv650 is a fun enough motor with standard or mild tuning on the road, couple that with the oh-so sweet handling of a vfr400 and you understand my reasoning

:mrgreen:

you should have forgot about the sv650 engine and the sv1000 and gone for the original version of the SV1000 engine, the TL1000 engine and had a killer ride. LITERALLY :p

Don't remind me!, I have had a tlR tlS and cagiva vraptor. It's a hoofin engine but like the sv1000 lump to many complications and near impossibilities

[xXBADGERXx]

I lusted after a TL and thought I would start with an SV . One bonus from all of this is that with the junking of the airbox for cones , you can modify a tank to take a hell of a lot more petrol than standard .

err.... not if its a vfr400 tank, the lost airbox kinda compensates for the engines vertical dimensions, that and the carbs...though if i get a tank fabricated i can have it made slightly wider and taller etc.

to be fair, im used to filling up every 70-80 miles! and thats on my bmw!!!!!

[Dangerous Dave]

the bodywork may stretch towards the newer and slightly slicker looking rfv400!!
Have you considered the Tyga (http://tyga-performance.com/site/index.php) RC211V replica bodywork for the VFR/RVF's?

http://tyga-performance.com/katonc30/katofrontleft3.jpg

Or are you looking to keep the bike a little more stealthy?

[Alpinestarhero]

This sounds like a brilliant project!

I will be keeping a very close eye on this; Hell, who knows - if I could get hold of an NC30 rolling chassis and a fuel injected SV engine, I would gie it a go too :-D

Good luck, please post lots and lots of lovely pictures

[plowsie]

Oh my god Dave, I really want that now!

[vardypeeps]

Goodluck with sorting your cooling etc out too I have heard that can be a pain in the bum.
And regarding the amount it's cost don't forget insurance when you come to claim all the mods!

[thor]

Just out of interest, is the SV engine much better than the standard VFR400? I thought everyone raved about those.:confused:

not sure about how stealthy i want it BUT NEVER IN A MILLION YEARS WILL I FIT A GOD_AWFUL TYGA bodykit like THAT! -nothing against tyga generally.. but id rather lick up my own puke.

OH GOOD GOD NO!!!! carb'd version thanks. 1=i already have most of everything 2=give me carbs over fuel injection anyday!.. lets just check that against all the bikes i currently own..... :rolleyes:oh yeah-carbs!

yes the joy of cooling, it'll be twin rads due to front wheel clearance, due to width of the sv engine i may go down the vtr route of side mounted, or similar to MX bikes with twin verticals giving downpipe clearane between.... lots of ideas going on there i tell you..:smt040

different kettle of fish. had/have both and allthough they are both absolutely brilliant in their own rite and both love being thrashed, the v4 is a high revving 4cylinder still and the sv is my personal shangri-la a 'twin':batman:

[yorkie_chris]

So put some flatslides and pod filters on it too then :-D

[vzzzbuxt]

oh forgot to say i got all excited as the headstock spacers/fitting kit came back from my machinery guy today so the ducati front is ready to fit, well bar a front wheel spindle that appears to have been misplaced over the last 2 weeks.(typical)

[vzzzbuxt]

can you let me finish the frame mods and install the engine into the chassis first?

...or should i say 'excellllllent...whats your credit card number again so i can pay for them ? ;)

[DarrenSV650S]

Update please :)

[tonydc]

Wow, can't wait to see how this develops.

I have both SV and NC30 and they're both great bikes. A hybrid will be great too I am sure!

Keep us posted on your progress...
