Out of interest, how are these got through mSVA as there is a max power of 15kW for quadricycles? Do you fit a restrictor or something?

Sure - fire your progress and pics on this thread!  Looking forward to seeing them!
Are you aware that it will need an IVA once you're finished (even though it's been previously registered)? Not teaching my granny to suck
eggs here, but thought I'd mention this early in your project build as plenty others with similar ideas to yours werent aware (it's
because you're taking the power beyond the max legal limit for the GS Moon buggies type-appropval).

It originally had a 16bhp 250cc engine, it's already road legal so I don't need a sva test

They're already type-approved with a puny engine Matt.
I guess Dixyman has a previously registered one and is doing a conversion???

Yep that's it, it's fully road legal with number plate and v5, I'm doing the conversion now and all I'm guna do is mot it with
the new engine and that's it cba with iva sva tests etc its cost me enough as it is ! Lol

You aren't aware then! 
You're right insofar that you don't need an SVA test Dixyman as that process is largely defunct, but you sure will need an IVA! See my
previous post!

I can get a iva test done at my local mot station so that's ok, it's just to say its save ain't it ? I've done engine
conversions before and it's been fine

Sorry buddy, but an IVA can only be fine at a VOSA centre, will cost you 500-ish quid and to pass you will have to re-engineer a fair bit of the
buggy.
You could of course stick 2 fingers up to the process and take the risk of running it on its current type approval... but you won't be insured,
and you'll be driving an illegal motor.

Fair enough. Be a decent spud though when the time comes to move it on and be sure to let any prospective owner know its not road legal (or return it
to its previous spec first).
So lets see your pics and hear your plans to stiffen the structure and upgrade your components to cope with the increased power.

I got the mot station to write to dvla when I put a bigger engine in my car to say it was done properly etc and they just changed the engine size on
the logbook is that not the case for a buggy ?
I've done extensive strengthening processes to the frame and I've got 4pot brembos to go on it with gaz adjustable shocks. I've also
got a sierra LSD for it so it ain't no bodge job !

I quite like the blog type builds, something like http://www.blogger.com/. It keeps everything in sections, having it on a timeline shows how things
progress over time, and you can add all sorts of stuff.

That's fine if you're changing motors in a previously registered CAR, but won't work for your circumstances as your buggy is
currently registered as a 'heavy quadricycle' and by increasing its power past the legal threshold it will become a 'motor
car' (and will therefore require IVA as its changed category).

Bit of a grey area mot wise as quads are tested as a class 4 with exemptions on emmisions . They used to get through with a mechanical lock on the
hydraulic line to the rear brakes but that's been changed . Pretty sure its still testable as its within the same class but applying the rules
to the bigger engine might mean it needs testing possibly a cat test if the engine is young enough . Personally if it was presented to me for test I
wouldn't do it as I'm not sure if the low powered quad exemptions apply with a larger engine fitted

It's not a grey area at all Froggy. You shouldn't test it simply because its no longer a heavy quadricycle! It's new unrestricted
Fireblade engine means that it's now a motor car.
After all, you wouldn't test a vehicle that was recorded as being a trike if it was presented with a recently added fourth wheel!

I test what is presented to me . Engine size doesn't dictate wether or not I can test it and there is no requirement or practical way to weigh a
quad . Its not down to me to decide wether or not it needs iva . Without looking at the flowchart I can't say wether it would need an emmisions
test .
Going from 3-4 wheels is a change of test class , changing engines makes no difference regardless of weight its still a class 4

Emissions won't come into it as the fireblade is a carb model with no cat anyway. U lot are worrying to much !

Until you hit something or someone hits you and you're not insured.

All you need to do is prove the engine is made before 1st August 1992 . The engine swap or weight makes no difference . Engine changes are tested on
whichever is oldest , your buggy is 1999 but is exempt due to being a quad . By the book it should be tested according to whatever age the new engine
is as its a class 4 vehicle , carb or not if its post 92 it comes into the cat test criteria . In reality you are unlikely to have any issues but
that's the way I see it going off the testing guide
