Nice!

I've never been but would love to go someday on a visit back to the US....although I get to go to the HD Museum for the first time in Milwaukee in a few weeks.

A business peer of mine spent quite a bit of time at Bonneville trying to crack 200mph on a modified Hayabusa. From what I learned from him it's even harder than it looks.

The closest I've been to it is seeing the World's Fastest Indian bikes(real and replica) in the flesh.

Wind drag, lack of traction on the salt and lack of barometric pressure are the major obsticles to overcome at Bonneville. Especially barometric pressure, at 6k' ASL, a naturally aspirated engine requires huge valves to flow enough air, and incredibly high static compression. The 110 octane gas will support cold cranking pressures in the range of 240 lbs. At sea level that equates to 12.5-13.5:1 static compression depending on the closing point of the intake valve. At 6k' ASL, the same engine/cam will require close to 16:1 compression to make the same CCP. To do it right, the engine gets built and tuned at the same elevation as Bonneville. In the real world, the engine gets built in NC, tuned, shake down runs and then pistons and heads get changed prior to the Bonneville. Maybe a day to tune on a buddy's dyno in Colorado on the way to the salt.

Honda CBX
 

One of my bikes is a 1981 Honda CBX 1000, 6 cylinder 24 valve sweetheart.

classic!...although I'd hate to do the valve adjustments and carb sync'ing

Had my carbs cleaned a few months ago. Very big job and expensive, but the bike went a bunch better afterwards. Unfortunatley I had a bad crash on it and almost lost a leg, so no riding for me for a while as healing is taking a bit of time.

The carb sync'ing is not really hard. It requires a six colum mercury vacume gauge. Simply connect each carb to its own colume on the gauge. Then adjust the other five butterflies until they are all drawing the same vacume. Idle AFR is sort of done the same way.

Tuning six carbs for power can be challenging as their are big differences in temps between the inside cylinders and outside cylinders. Add in the different port profiles for the various cylinders across the head and getting everything out of each hole is alot of trial and error.

Awesome........

Being in the motorbike biz, it drives me nuts seeing Honda come out with some awesome bikes while it also comes out with generic clones of Harley-Davidson.

No matter how good their cruisers are(and they can be surprisingly good), they are still perceived by most as clones and the red haired step children of the Harley dominated cruiser community.

If I was running Honda marketing, I'd say "We're bringing back a limited edition CBX."

"We are only going to make X many(the first year)".

"They are going to cost X dollars paid in advance."

People would go nuts.......and the program would be pre-funded. :)

The CBX is a big part of the Honda legacy......I've got a photo of me as a kid on one with my uncle that drove my desire for motorcycles and entering the business.

It's a shame really.....they've brought back brands like Norton.....I don't see why they can't bring back a brand within a brand in the form of a new CBX.

Anywho.....nice bike.

ouch, hope ya heel well, and fast. that hurts just looking at it.:eek:

Thanks Glebo, funnily enough, it didnt hurt a bit, which is more than I can say for the broken ribs and shoulder.

The other bike
 

The other one is a 1978 Triumph Bonneville 750 cc

An update. Not the Bonneville land speed bike, but a bike I am building for a friend. Very similar to my race bike.

/\ /\ /\ Haaa, gotta luv it, in the kitchenette no less....LOL

They only place to build...close to the fridge..

Ohlins up front?

What about on the rear?

You might be able to scare up some Ohlins rear shocks(not sure if they'd fit size wise, but maybe) 2nd hand off of the Yamaha XJRs that came as standard upgrades a number of years back.....could be some in good knick from a salvaged bike.

I like the direction you're going in.....looks like a reinterpretation of an old FXR.

Thanks for the kind words.

That is an FXR frame. The front fork is a set of KYB 43mm inverted forks that have been lengthened by three inches.

Look at the area between the lower tube and the caliper bracket, there is an extension in there. Inside the fork the dampener tube is three inches longer, final was 1200 grit and then hard place anodized. Very slippery.

The rear shocks are going to be custom built by GMD Atlanta once the bike is completely built and a true rear axle weight is known.

Here are some pics of the fork extensions in various stages of the build and the bike in its previous configuration. The fork with the red fender is from a tube frame Buell. The Buell fork was great for going straight but was too short for the twisties, plus it had side mounted calipers. The 43mm KYB is a much better platform and more worthy of the work required to extend it.

Awesome effort....I'd be keen to see the finished product once done. My workshop manager is going to get a kick out of this one. Him and his Dad are working on an outside the square kind of bike....trying to mesh old school Harley with more modern Buell/Ohlins bits too.

They're trying to shoehorn a TwinCam motor/trans into an FXR frame.

I'm working on a 48 at the moment....but will be 80% stock.....far more show than go.
