RGV250 chassis with SV650 motor....

[fimpBIKES]

Can it be done?? [:I]

CR500 ?

[davio]

fuck i hope so ,, what a gr8 idea n when do we start?( by we i mean u of course)

[fimpBIKES]

the other option is a XR600....

[davio]

ive had a similar idea fer yrs but was always a rotax motor ,, mate i really reckon ur onto a fuckin gr8 idea there ,, good motor cheap and available,,proven top donor chassis ,and the twin will be narrower than the 2 stroke donk ,all u gotta do is make room for the rear cylinder ,, pleeeeeeeease have a go ,im to poor and i really waane see

[oldskool]

The motor will be wider than an RGV motor and I dont think the RGV frame will take the stress.
Just my 2 cents, nice idea tho.

[miniman1]

Anything can be done provided u either have the experience/know-how or have the means to keep throwing
cash at it till its done.

Have a go mate, would love to see the end result!!!!

it should be compulsory

[Fight_fan]

Give Ben a call! If it can be done, he'd be ur man!

[Jockney Rebel]

fimp what ya doing with the RGs engine?

[OZ750L]

If they can get an RG500 motor in ya should be able to do it. Like it's been said, cubic dollars will make it happen.

Saw a Buell motor being fitted into an XR650 the other day. Something different.

[fimpBIKES]

nah jockney
this is a new RGV250 rolling chassis i have coming my way :D

wanna by a 95% done RG250?

[ST31TH]

ive seen it done in an nsr 250 they dropped a cr500 in it and it nearly shook it to pieces i have an nsr 150 frame i was thinkin of it 2

how much

[Stocky]

The frame might need some bracing etc to make it stiff enough etc.

Given that, just jam a TL1000 engine in there.

If you are going to fit another engine it may as well be stupidly over powered ;)

[gixkat]

Someones gotta do it and your the man Fimp;), actually i dont know if your the man for the job or not, but like i said someones got to do it:D, like others have mentioned bracing the frame is a must do!

[fimpBIKES]

yeah, i know the TL motor is tempting...

but this will end up being a after-learners bike for annie

using the XR600 motor would probably be easiest (depending on whether i think i can make a profit on the bike as a whole)
but the power seems kinda lacking in that motor
(45bhp with 52Nm)

the SV motor will cost more, cos it needs a rebuild
but its (68hbp at 62Nm)
plus i need carbs or injection from a newer model


i guess if the SV motor will slot in then its the only way to go

UNLESS we can extract more out of the XR motor later on....

You could buy that and flog all the bits you don't need

[TurboKat]

Do it Fimp, the RGV/SV6 conversion is SCREAMING to be done by somebody [:p] It would be such a trick unit, I'm surprised it hasn't been done (if it has, I'd love to see pics/details)
Don't bother with an XR6 motor, they are a bit gutless stock & if you want decent power from one they get real hot when ridden on the road, if it's a big single you want go for an XR 650 IMHO.
Did you buy Rexies/Chris' roller?

[fimpBIKES]

yeah i guess, but then what do i do with the SV650 lump i have sitting here?

did i mention that?

here is what i have laying around (relevant to this particular project anyways)
- Rolling chassis of RGV250
- Complete XR600, with good motor and not sure how much else of it is good
- SV650 motor from my old bike with probably stuffed big-end bearing
- Profiles in foam to make a custom tail (which was going to go onto the RG250)

i wouldl go the whole SV large, but i have tried to sell this SV650 motor for as low as $300 and no-one wanted it
even blokes i know who raced the fuckers!
still, there isnt much wiring in it if i stick with carbs so it should suit this sort of thing

i just know it will be a lot more effort than a supermono sort of thing
and not sure if the extra horsepower is going to make it worth the hassle

oh, but the other factor is that i would prefer electric start since it wont be my bike really



jim, how about $500 for the RG and all the extras i have for it sitting around (fairings etc)
probably enough to have a nice replica once its all together, the wiring is all sorted now with a new stator and harness

happy to drop it off if u need me to :)

[Jockney Rebel]

ill have a word with you when i see you at casino mate, im interested

[fimpBIKES]

sounds great jim, looking forward to many words in casino :)

[fimpBIKES]

looking into it more, im thinking now that the XR is the way to go

but either way, how hard is it to get these sorts of things registered/engineered in NSW
or are they a track only sort of thing?

[Hillsy]

I remember a guy that used to put BSA twins into RGV chassis. He was in NSW and he had them registered so it's do-able.

Maybe PM Chopaweeza - he built an XR bobber not too long ago (??)

[Stocky]

If you have the motor and the frame what are you asking us for ?

Jam that 650 in there and show us how it's done !

Don't do that... If someone buys my VFR soon I wanna buy that SV and build a cafe fighter with it... :)
Oh, yes, you must rebuild your SV650 engine and slot it in. BTW, how do you do a big end in an SV engine? Run it out of oil...?

[Weaselman]

I like the idea of the SV motor.

I dont see the RGV frame struggling to take the stresses they were well built for what they were.
I personally say go the twin.

And you'll need and engineering cert on the swap

[Jockney Rebel]

nah stick a kwak triple init and realy scare yerself

[Hillsy]

Well yes - most commonly by doing big long wheelies. This tends to starve the bottom end...dakka, dakka, dakka....

[fimpBIKES]

no big wheelies, i just made the mistake of buying an ex-demo bike i think

had the engine rebuilt once but i suspect they fucked something up, i didnt get the impression that the guy new 100% what he was doing


im just trying to get in touch with the local auto-engineer here
according to RTA, for engine swaps you're only allowed
Tare Weight * 3 = Allowable CC's
which for the RGV = only about 150kg*3 = 450cc :(

but i need to talk to the engineer, cos what i actually doing in this case with the XR motor is going from 60bhp with the standard motor down to the XR's 50ish ;)

failing that it would mean individually constructed vehicle time...
anyone know how much thats worth??

That formula seems a bit strange, for example if I was to change the engine in my Bking I could only go 220*3. That would mean 660cc, which is less than half the original engine size?

[fimpBIKES]

yeah, the formula is fucked
thats the point i plan to argue with the engineer :D




anyways, i figured this out earlier

using the XR600 engine
(45bhp with 52Nm), about 8000rpm max

the SV motor will cost more, cos it needs a rebuild and carbs etc
but its (68bhp at 62Nm), about 11 500rpm max

so using my fancy linear interpolation skills, assuming that the dyno is sort of linear

that means at 8000rpm the SV makes 47bhp



so there you go! Probably pretty close low-down…



never looked at it that way, plus you have the added mass of the SV engine, and extra carbi, a radiator

fuck-it, the XR is looking better and better…..
:D


now i just need to make sure it wont be a track-only bike!

[_M_]

The equation in QLD is something like 1.2 x the original engine cubic size, i thought it was simular aus wide.

Don't give up yet! I know a lot of the supermono guys I uesd to race with did exactly that build and had issues with vibrations cracking the engine mounts and cradles, a problem the SV won't have as it has perfect primary balance.

Hey, if this guy can make it work in a KR1-S chassis it's doable for a RGV

ok i know that was a v-twin but it sounded like it had an awfull knock .....and cmon fimp fuck the XR600 mate go the sv it will be way more fun ......i thought you liked a challenge mate

[loosebruce]

It might be cheaper and easier finding an SV frame and getting all the RGV suspension and wheels onto it.
Less rego hassles and it probably wouldn't be any heavier.

bruce, your a FUCKING GENIOUS!!!!!!


love ya!


yeah rod, thats what an SV with pods'll sound like
i used to hate that ticking, reminded me of how much money the rebuild cost me [xx(]

[davio]

lmao , bruce is quite smart ,,, the rest of us are idiots

RGV suspension or just Gixxar suspension. I know K4/K5 Gixxer 600/750 front end is a direct swap in the injected SV650 frame :)

the RGV had around 65 RHP apparently,i doubt the SV650 would be to much different there.My GSXR hasn't broken its RGV banana swingarm,yet,and its about twice the power of the RGV.

[fimpBIKES]

my old SV dynod out at the high 60's at the wheel from memory


i checked out the bikes yesterday, seem good
pretty sure that the SV motor could be made to fit :D

still waiting to hear back from the certifing engineer about legalities....

[TurboKat]

Fuck the legalities Fimp, just build it & ride it.
I didn't think as the Commander of the Coalition for the Liberation of Itinerant Tree dwellers you would feel the need to conform to any legal requirements [V]
Maybe you should join up with the less militant Liberate Apes Before Imprisoning Apes movement, they might be more your style ;)

[fimpBIKES]

was wondering if anyone would get that :D


well, i just got off the phone with the engineer, he says the vehicle guidelines are for cars and not to worry about them
Can do whatever I want as long as I don’t mess with the main frame too much

This swap would mean 2 new lower frame rails, which bolt on anyways so not a problem

I will need a noise test ($50)
And a certificate ($350) and im in the clear

Greenlight to do what ever I want as long as the power doesn’t go up by “too much”

So SV engine it is {:D]

the idea is to end up with a lower seat-height, light, torquey bike that can be a daily for anne and a good little bike for trackdays

might have a mate who needs a cheap learner legal bike too, so that takes care of the XR i hope

[DiscoDan]

Yee haa. Let the games begin

[RUSS M8]

Really looking forward to this build. Like seeing a dream turn into reality! You might start a trend ya know... :)

[nelpd96]

Fimp,
The engineer is giving you a bum steer if you are in NSW because by the end of April all engineer will have to re-apply to be listed as a signatory because NSW is changing it's system over to the NCOP. This means that there are a number of codes that are applicable to motorbikes. I will be listed in NSW after the ramp up the new list so I should be able to help you out.

Cheers
Paul

[fimpBIKES]

thanks mate, so will i be able to get it registered or not?

[scottyrrx]

hi the 650 does fit and goes really well but i put it in an aprilia rs 125 the cr500 has also been done but not by my self but i recall that was silly quick but shook everything loos on a regular basis if you want pics of the 650 let me know

A fella in Adelaide has a single in a RGV Chassis, dunno what size/sort of Engina it is, b ut she's definatley a Single!

Zipps around Mallala quite well!

[BANDITROD]

fuck yeah fimp no your talking mate get into it man i wanna see this beast at AFR10

[fimpBIKES]

hi scotty, would love to see pics mate

[scottyrrx]

not forgot guys about the pictures but struggling to find them and then i have to get them to the correct size i think i already upset cbrrt because of using large pictures and dont want to upset him any more may need is input in future so will get it sorted soon

[LAW]

Hey all, just wondering if there was ever a happy ending to this?

I'm desperately keen to slot a 650 into an RGV/RS frame and I will buy the man a beer who can give me any info/pics. :D

[crazymofo]

bring it to my garage, i'll sort ya

cheers.joe.

[fimpBIKES]

you would need to redo the rear shock crossmember on the frame
this makes it unrego-able in nsw

unless u do it as an individually constructed vehicle it would be track-only

[LAW]

Haha, hey there CrazyMofo.

I've got a 650 engine laying around and there's a wrecker down the road, I would be very tempted to apply for experimental rego but for now it would be a trackbike.

I think I'm going to need a bigger hammer. :D
