Thinking of modifying the Gixxer.

OH you've changed ya tune!!!! (blade motor)

At least half the enjoyment would come from actually doing it.

Yeah u should do it... i'm trying to talk colin in to doing some stuff to his bike!! SOOOO you better do yours too as not to be out done! muuhahahaha u cant be beat by an R1 now can you!

I did a tally up of the cost of titanium bolts etc, they alone will cost $1000 from the site I listed above. Hmmm, not sure of the actual weight savings so don't know whether I could justify that. A lot of people who have gone down the path I'm planning seem to have done it though. I wonder what the reduction would be, they advertise a 40% saving. A few hunderd grammes?

mate .. go for lighter wheels for sure .. here is an article that should tell the story..


i just got done with the motor on the FJ.. cant tell you how much fun giving your trusted steed a birthday is .. ( 1314 Weisco kit, stroker crank, heads, cams, timing advance, gearing and a few sundry other tweaks..)

REDUCING THE WEIGHT OF YOUR WHEELS IS THE MOST IMPORTANT PERFORMANCE CHANGE THAT YOU CAN MAKE TO YOU MOTORCYCLE!
Lighter wheels will make a major difference in the handling of your bike. They will also greatly improve the acceleration and deceleration “braking” of your bike for the following reasons.
Static Weight: Each ounce of reduction of the wheels weight is equivalent to 4 ounces on the sprung part of the bike. Magnesium wheels will normally weigh at least 10 pounds less than your stock aluminum wheels. This is equal to 40 pounds of weight reduction on the bike. That’s alot of carbon and titanium.
Dynamic Weight: This is the weight reduction on the rim of the wheel and this is where the ACTION is. EACH OUNCE OF WEIGHT REDUCTION ON THE RIM IS EQUAL TO ABOUT 25 POUNDS OF WEIGHT AT 100 MPH!
This is real weight that must be turned, accelerated, and stopped. As an example, a pair of magnesium wheels will normally reduce the total rim weight of the two wheels by at least 20 ounces. This means that your bike will weigh 500 pounds less at 100 MPH.
At all other speeds the reduction is in relation to the velocity of the bike. As you increase your speed the weight will increase exponentially.
The following formula will enable you to figure for yourself the impact of dynamic weight on your bike.
Given:
V=Speed of your bike in MPH.
D=Diameter, outside of tire in inches.
G=G Force (Times force of gravity)


So: 1 oz. At the surface of the tire at 100 MPH produces a force of 600.37
ounces, or 37.52 pounds.
Force at the rim: Let’s say the rim is 2/3 the way from the axle to the surface of the tire. This equates to 17 inches for the wheel and 10 inches total for the tire. To arrive at the percentage, divide 17 by 27 which will give you 63% which is the distance of the rim from the axle in relation to the overall diameter of the wheel and tire.
Multiply the force at the surface by 63%. 1 ounce on the rim is about 23.64 pounds.

2.2 pounds per kilo - 1.6 kilometers per mile..

aftermarket rims are my next investment..

Sorry I'm not too sure what your setup is, but the cheapest way to make your bike easier to wrestle over could be a longer clipon, even a centimetre or two would be a huge difference to the tourque you could throw on the wheel, especially with only one arm, and while you're at it, why not get rid of the left hand clipon and switchgear completely, save weight and make it near on impossible to pinch at the same time.

Have you seen the articles on the Czecher Superlight? It's here: http://www.motorcycle-usa.com/Articl...ArticleID=3012
and although it's a Gixxer 750 it looks like they've concentrated on weight saving and handling rather than outright horsepower so you might find it useful.

Also have a look at www.durbahn.de. This guy is amazing, and manages to knock over 50kg (yup, 50kg) off the weight of a Honda SP1/2. His next project is a K6 Gixxer with similar things in mind so it'll be worth a look for you too.

I agree on the horsepower thang. Those K1/2's are absolute gruntmasters, the later versions seem to have pinched from the midrange to improve the top end.

Interesting that you were impressed with the 999R you were playing with, 'cos it's substantially heavier and down on power compared to your Gixxer. Good gear on 'em though and all the grunt is right where you need it. I won't mention the difference in price......

What the factories give us is a mass produced compromise at best, so it's good to see someone making a more personal statement. Don't forget to post the piccies!

if you go with that undertray from Canada just check with there distributor in Aussie first,the guys in canada insist on using the most expensive postage service over there...when i bought mine i think it was an xtra $100 us just for the bloody postage.as i say check with the guys in AUSSIE first...just a matter of sussing out whats cheaper know that the dollar has gone down so much.

[onearmedbandit]

Thanks 98tls, I'll keep that in mind.

Got the price on a set of carbon rims today, less than what I expected but more than what I was quoted by a friend. Not his fault, blame it on the exhange rate. So I could have a set of carbons for $4700, which like I said is less then the $6000 I was expecting. They could be here in a week as well I was told. Going to pop into see the guy tomorrow or Wednesday to look at some samples he's got, and also inquire with him about Marchesini Magnesium rims, apparently he's done them quite cheap as well. A set of 5 spoke Marchesini rims would look quite cool and offer a decent weight saving, just not as cool and more importantly not as light as carbons. Decisions decisions...

Has anyone dealt with Just Fairings before? I was put onto them today for carbon work, anyone up north know these guys or can help me with finding out a bit more about them? Thanks.

Any word on that Ohlin stuff yet Sensei?

[98tls]

i bought a hugger off them for the TL....great service..seemed like a top bloke.

At least half the enjoyment would come from actually doing it. The other half would be enjoying the benefits and knowing that it's your work. And how often do you see carbon fibred GSXR's coming up? Also I've just been put in the right direction for carbon rims, I'll know if it's on tomorrow.

Perhaps buy a race bike and scavenge all the bits off it you want? Then put whatevers left back into the race bike Save you crashing the tricked one at the track

I see where you're going, but a lot of the bit's I'm after won't be on a race bike here or will need rebuilding. I'm still looking at my options as far as what to buy, where to buy, etc. Nothing is set in concrete but the ball is rolling.

Hope you got the xls file I sent you... outlined about $17k worth of crap over two shops Wouldn't be much left but carbon mind you

Don't have office on my home pc. Any program you can suggest that I can use to view it?

Checked out the carbon rims today, BST goodness. Was beginning to think that I'd go a set of Marchesini rims but after looking further into it I'm much better off to go down the carbon path. When I talked to the local supplier for them he didn't say what brand they were so I was a little hesitant about buying an unknown company's product, but now that I know they are BST they are worth every dollar he's asking, and more. Only a week to get them in as well, price includes fitting too.
