BEC Tuning
What are the options for tuning bike engines?
With cars, there's all the usual stuff that's avaulable from every other engine shop, from the cheaper bits right through to expensive
upgrade.
Bike engine stuff seems to be only carb jetting and power commanders - is there anywhere that sells other perfoamnce parts?

Absolutely loads mate. Depends on what engine and how much money you got...
Big bores, skimmed heads, blueprints, cams, filters, exhausts, turbos, superchargers.......
Where do you think all the BSB teams and privateers get their uprated engines from???
Try searching bigccracing, TTS, etc etc

Ah, there's my mistake - I was looking at companies like Demon Thieves etc.
I was wanting to upgrade the engine over tie, so would start with the smaller items and work my way through the goodies until I'm satisfied with
the performance.
How does tuning effect the reliablility in a car installation (obviously, like any tuning, things like clutches etc. would need upgrading to handle
the extra power, but this'll be done anyway)

TBH - the money vs power you spend upgrading a BE is pointless, unless you go Nitro, Turbo. The respective companies have already done pretty much
what can be done for you. Airflow is pretty much all you can do as the restrictions on BE is noise.
Regarding reliability... almost every serious upgrade will take more out of the transmission related parts and these will fail much quicker in a
BEC.
If you think it's still worth it - go for it!
If you have plenty of money to spend "gaining" loads of power - buy a Pinto and start from there... it'll cost loads, but
you'll be starting from a much lower base to achieve a similar figure - but then you'll get much more longevity!

Agree with Steve, bike engine tuning seems to be a lot more expensie for the gains you get, for example when I had the 919 blade with ~130bhp it would
have cost more to tune it to ~155bhp than swap to an R1 with the same power, and if you do the upgrade you also lose the advantage of having a stock
engine (ie cheap replacement) and also with the more powerful stock engine you have a gearbox / clutch designed to cope with that power to start
with.

That's what I was weighing up for the future - do I spend money progressively tuning or do I save it up and upgrade to something bigger.
So, apart from a re-jet and maybe a barnettt clutch, I'll just leave it alone.

If you really want decent horsepower, the man to spea to is Nicky Kennedy in Scarboghorror (01723 354395). He can get horsepower where others
fail...
In the late '90s, Tony Scott was getting 106bhp at the rear wheel of the factory SS600 CBR600s. Nicky was getting 113, and it was properly
usable!
The only problem is that you'll well and truly pay for the priviledge as it's a lot of work....
Spin 'er off Well...

I think I'll be ok with a re-jet and save the money.
Might even think about just getting the car on the road in the first place (progress is alarmingly slow and my mind is getting too far ahead at the
moment!)

Best idea is get it thro' sva & on the road, then you can play about with it once you know what you have (& whether you actually need
more power) & look at the respective costs for tuning or upgrades etc.
I no longer run Furore Products or Furore Cars Ltd, but would still highly recommend them for Acewell dashes, projector headlights, dominator
headlights, indicators, mirrors etc, best prices in the UK! Take a look at http://www.furoreproducts.co.uk/ or find more parts on Ebay, user names
furoreltd & furoreproducts, discounts available for LCB users.
Don't forget Stainless Steel Braided brake hoses, made to your exact requirements in any of around 16 colours.
