Ben is that from personal experience ?
Lot of people use the Quaife box - can't be all bad.
Mines under warranty - if it dies I'll get a new one

as far as I remember, homemade leccy reverse is usually done with a starter motor engaging with a sprocket on the propshaft, with your choice of
switching, etc. to try to make sure you don't engage it while in a forward gear, or over-running it, etc.

bike engines are more highly tuned that car engines and rev harder so need to look after them, but regular oil and filter changes with good quality
parts will look after them. Also i guess that the fact the engine only ment to haul maybe 250-300kg about in its normaly fitment it wont like the fact
its needs to cart swo much extra weight about, maybe thats why some give up

Can someone please list this long list of fragile bike engines that have gone bang ?
Tuned blade, over 15k miles in car, thrashed to **** everywhere.
Off the top of my head here is a short list of CEC engines that have let me down during my "racing" days.
Blown, Pinto x2, mini (bmc) blown countless, 205 block atmo cosworth (blown) RV8 blown. Peugeot 205 blown x 2. Blade, cant blow the dam thing, still
waiting to upgrade to a ZX12R, guess it will let go one day.

Hi, here are some piccys of electric reverse setups.
As for reliability, a well looked after bike motor can be regularly thrashed to within an inch of it's life. What they don't like is abuse,
ie massive over rev on down changes or clumsy, violent gearchanges.

Thanks for all the info guys. As far as the reliability goes, im not too sure yet. Still need to buzz around for a while.

Are there any bike engined middys around. I would like to hear what they have to say.
BE's will bring the weight of my car down to a minimum! thats cool, but it shouldnt take up too much time maintaining it

I think the new Quaife one is probably the first one that does'nt have a reputation for dying. Still eats a %age of the BHP (okay it's
small %  )

Not sure I like the idea of a circular saw blade whizzing round next to my thigh... even less that a honking great pole whissing round next to me

Looking at Mike's last photo where you can see the engine about 300mm forward of the diff I'd guess that's middy. Quite happy to be
corrected though.

Yes, tis a middy. Built in the states with a Kawasaki motor. Odd hot rod looking car with the bike front end! I'm trying to find the link now

Bike engines are even more reliable in a middy, the engine is mounted more like it was in the bike.
Ran a blackbird motor know as the "cat" it used a fair few of its lifes up.
Blown oil cooler hose followed by a fire, survived.
lost sump plug, survived.

reliability is the person driving and maintaining it. EPR, anyone thought about using a multy V belt with a magnetic coupling used on airco pumps?
In combination with an reduction starter with a pully. Big circlesawblade doesnt get me going either. You can always make a flintstone trapdoor for
FPR

Not an expert, a new kit car owner but from my limited experience chose a cec.
I had passenger ride in fireblade bec and sounds beautiful, bit harsh gear changes etc but a real different experience to a normal car. But isnt that
why we get these cars any way.
However as a lot of my driving is with a passenger I needed more torque and ultimately power, so went for a cec with 235hp xe engine.
Its heavier than a bec, around 600kgs, but has reverse, revs to 8500rpm, sounds mean, high 5th gear, 3000 rpm at 75mph and its quick enough around
400hp/tonne.
Must admit though I still love the idea of a bec, in some ways its a purer concept, light weight and loads of revs and may one day go for this one
i've been let in gently to this new experience by cec
Both are great!

i have a quaif reverse on my BEC and its great. Got to reverse slowly though but enough to not have to get out and push. cost about 600-700 for it and
it adds to the weight but i found it better thatn an electric one.
all depends on how oftern you are going to be driving in towns and might need that reverse.....................
