would it be possible to fit these little gems into my early vt 250 frame
and what are approx mesurments across the cylinder heads inline 4
say a suzuki or cbr just for general idea doesint have to inch perfect
my frame is the one with detacable frame cle square section tubing mid 80s
but after the round tubular first vt 250
it be if the cylinders fir between the cradle at the bottom of the frame the cylinder are forward slanting also

I haven't heard of anyone putting a 4 cylinder into a VT250 frame but that doesn't mean it hasn't been done.
If you're just looking at options for what to put into the VT250 frame you've already got you might want to look into a big single. I've seen a couple of projects online where people have put a Yamaha SRX600 engine into a Spada frame. (Which isn't what you've got but I assume the important dimensions are similar since they had the same engine from the factory.) I reckon a 600cc single in a VT250 frame would be shedloads of fun.

I'm with Ender on this, big single all the way. Would be heaps of fun.
I'm still meaning to drop by and look at that RC36 too :niceone:

Frame is trash, waste of just about any motor you put in it.

its doable, but youll need to get custom engine mounts which will require certs. in doing this, the power output may increase enough that you need to do brake modifications as well, and if youre gonna do that, you might as well look into an upgraded front end as well.
Seems like a lot of effort for no gain to me, but if its a project to do 'Just because' then fuckit, go for it.
I think a big single would be a better idea, like an XR 600 or something would be sweet, probably quite alot easier too.

Yes i think single myself well my ideal whould be like rgv frame with single motor maybe 400cc
but just this motor avaible minus carbs and just bare motor for 325.00 which is cheap
And not sure when single engine will be avaible i had no luck with getting orginal vt 250 motor
I dont think frames are shit look and feel pretty good to me when had engine in it nice light
Ats always good foundation to work with , know old gsx 1100 frame that be shit to put single engine into hehe or worse a cb 750 oh the shame
I think go with the Yam engine i like them you need rev thats only down side compared with
relaxed single mind you vt motors where rev happy too so not to out charcter
Thanks for the replys and your most welcome to call over dude

I get what your saying but am not going race it so you know just want make use of something
I paid 500.00 for insteed going okay i thow that all away scarp itfor 10 bucks
I hardly think big demand for vt 250 parts from 80s model somehow

I'm with ^him^.
What about putting an FZR250 in an FZR250 frame? They're quite a nice handler. If you're REALLY keen I'v got a mint 3LN FZR250 motor for sale...........

There was a 250 inline 4 transplanted into small mx frame a few years ago so anything is possible for a cost of cash and time .
Wouldnt that v motor end up costing alot more if you need get carbs ,exaust and electrics.trying to get the exausts out of the v motor wouldnt be easy in that vt frame also.
A nice 500-600 single would end up a better bike in my opinion.xr600 maybe or xt .there must be some cheap complete dirty bikes that will provide all the gear you need and a slender single will be alot easier to make good mounts for.Also a inline four will be hard to get chain alignment when the vt had a slender motor.

You would'nt happen to remember where you saw that? Ive been thinking the same with my spada now 'cause she's a bit beat up & would make a nice project.
not wanting to hijack the thread either...

Unfortunately not, I had a bit of a search when I first posted that but wasn't able to find it. I'm still not having much luck but I'm pretty sure I wasn't imagining it. I remember there being a decent sized page about a guy in the states who'd kept a record of his build, which was based on another SRX engined Spada that his mate had. This was at least 3 years ago so the domain might've expired since it wasn't on a big forum.

cheers anyway Ender...i tried a Goggle search with the words 600 engine in a Spada & found out that Spada is a word used in malaysia for gay stuff supposedly:yes: Apt I 'spose seeing its a honda.
I'll PM Gatch....he was talking about "doing it" with his:blink:

Plus unlike vt 250 engine rebuilding them is possible and doesint cost thousands
I always wanted to get hot up parts for a honda single like flat side carb kelhein mild cam
Road tires mmmmmm mind you with spoked rims mmm super motard retro
Say just rev counter and digtial speedo single seat port hills special
mind you dreaming aside just a engine is better than a door stop the garage
I do have spare xr 200 engine that cant get back toghter found had striped 4th gear fixed that
But getting cases back toghter must be how i fitted the gearbox or kickstarter just wont fit right
yes your right just weather i can get a good single engine i prefer 400cc or around that
I had xl600 rf was bit dispointed with it had the twin carbs it didint like top at 50kph
I thought was whole point single felxable ;-) xl 250 rf was more refined
I always like honda gb 500s 400s one those engines whould like nice
Think inline whould look werid too out of place but i see i brought the engine know
So either keep it get to run then sell it as a runner or put it into fzr 250 frame
But then i got get all the rest of the running gear aghhh

Yes i rekon those close ratio gears it be wheelie machine hehe opps not that approve such
rekless behaviour i be bad infulence on certain bros riding dude.
Also has green machine remain nameless with sometihng to do with wheel hmmm
Ps as for the rc36 i neraly had thing fall over on me last night getting the front headers of
As it sitting on the exhust underneth the sump me pulling on the headers hd bike rocking and rolling
oH l attach some pics can anyone tell what these pipes are i need order new set and think for water , but then again chould be for oil am cofussed and me parts man at city honda chouldint
find them to order new ones
thes two chrome pipes about 4 mm round go into two rubber hoses and round like water or fuel pump not the main water pump though got me stumped
aslo do you think okay to put back on after i checked them they don't seem blocked so ?
The vfr 800 doesint have these pipes at all all there just under the rocker cover but agaist the cylinder head. just below the exhust headers where go into the head

I'd have to look at the bike to tell you.
What you could do though, is drill/tap those brackets on the end of the pipe and throw some braided line in there instead. ;)

Actually, blowing it out with compressed air is quite a good idea!
A VFR flute would be pretty neat.
Braided line will handle whatever you throw at it, excluding thermite.
