I remember reading through a post were a guy detailed how he went about makeing a CF tank for his bike. It looked awsome all right, but there was one thing that always bugged me about it. In an accident, a steel or even an alloy tank will deform on impact, absorbing a lot of the force before it fails. And even when it does fail it will likely only be a relatively small split or puncture. Unlike steel, carbon fibre dosn't have that give/elasticity, so once it reaches it's limit it will fail much more completely leaving the rider laying in or possibly even covered in fuel.
You could run a bladder inside the tank (at some considerable cost) that could solve this issue, but it's a lot of cash for the cool factor in this case.
The other options are to rap a standard tank in CF to give you the cool look at a much lower price, or you could go the extra mile and have an alloy tank made and fit a CF cover over it.

Mr HC
Iam thinking of changing the ride height on my Rgv/lc and wonder if you could you do me a favour [-o< and measure with your bike up right from the floor to the top bolt that holds the grab rail on,

I's the same problem you used to get with fibreglass tanks in the 60's and early 70's. You could get some great race and road tanks and seat units which were fairly cheap to buy and looked great. But if you dropped a bike you could have major problems
- They were eventually banned.
Not certain that cf would be a good material for a tank anyway as the trend for more and more ethanol in fuel (E5 soon to be E10 in UK normal unleaded) would probably wreck it in no time unless it was coated on the inside with an ethanol resistant sealant to keep the fuel away from the carbon.

I have a plastic tank on the Buell and it was fine until this ethanol was introduced into the petrol
It is bubbling left right and centre after being fine since 2001
On the Buell site they are having alloy tanks made but at £800
Was going to have a cover made in carbon and get that painted so the bubbling paint can carry on as you won't see it
There is a bloke with all carbon LC bodywork but he just had the original metal tank wrapped

Same problem with the Ducati Sport like I have. That's a plastic tank and they are having problems in the US with tank spread through E10 which they have already use in their fuel.
E10 is being introduced in the UK allegedly some time this year replacing the E5 we currently have in normal unleaded so I have already changed to using super unleaded in all my bikes as it does not currently have any ethanol in it (unless you happen to live in the South West of the UK). It costs more but in the long run is a damn sight cheaper than replacing a tank, rubber hoses, carb or injector bits etc which were not designed to be ethanol resistant.
Bloody fuel suppliers won't even add it to fuel in their main storage/production facilities it is only added when it gets to the delivery tanker.
Stuff bio fuels, EU rulings and eco tw*ts,
bring back lead
did me no harm
smoke the buggers out!!!!!!!!!!!

67.91bhp on the dyno today
Let's call it 68bhp
All the gains came mostly from Kenny's TSA pipes
Main jet was too rich (152) so maybe another 1-2 bhp jetting down (150) but will leave it at that I think

It's making 60bhp at 9100rpm and the next 7bhp in the next 1100 revs
It was still gaining but told Kev not to rev it higher
35 ft pounds of torque from 7000rpm to peak too

Fueling needs a bit of tweaking but feels great on the road

That torque curve is something else! It's as if you converted it into a 4-stroke lol.
Impressive stuff.

That's the powervalves doing their job then but it feels very torquey on the road and very grunty for such a small CC bike
Got some more barrels on now (same tuner but inlets and boost port opened up) and some Vforce 4 reeds (Slightly bigger than VForce 3's and reed stops return) so will be interesting to see if they have lost or gained on the dyno
