New Bike Frame Project

Larry-
The plan is to race Bubs.   I will have the 1000cc Buell drag bike ready. This build could be ready. Plus the nephews are pushing for Bubs.

Hey Joe, no Bub's for me this year. Should have 2 bikes for Speedweek this year. My 1350 and another 2000. Was hoping to have the 2000 ready for El M this weekend but no luck...

Got son and grandson over today.   Welding up the frame.



Going good.  Who knows this thing may get finished yet.

My son Joe came over and finished all the frame structure welding yesterday. 



I put the mock up engine in, assembled the front end and put the wheels on.  I have tires on the way and then it will be a roller.

Looks pretty stout Joe, nice work. Will you use the stock airbox?

[55chevr]

I am planning on using the stock airbox. Not sure on how I will duct the intakes.  I probably will fab an air box out of aluminum later on.  The stock air box is the highest part of the bike right now.

Nice looking frame, Joe.  It looks wide at the seat area.  Try your riding position to make sure you can get your legs tucked in where you want them.  Better to find out now than on the track.

Those stock air boxes on Japanese bikes are magic. The tuneup depends on them.

I pulled the air cleaner from a Honda 500 Interceptor and lost 27 MPH. It didn't even

want to run with the choke on. There's more to that air box than meets the eye.

The only problem with the stock air box is that it will be the highest point on the bike.  I noticed that the mini sprint cars use zx10 engines with different air box with success.  This will require some research.

something to think about, Joe--

the sprint cars are at full throttle for short bursts on the round the round.
the Zx 10 R will be wot for 1 - 3 miles, or more. that bike could wind up on the long course at Bonneville.

the air box application could make a difference in how it performs.

I am sure that the inlet length and the plenum volume have a lot of engineering invested in them.   I am planning on running the stock box initially. The inlet tubes are going to be a bigger challenge.  The reason I want to go a different way then the stock air box is that it will be proud 4 inches over the engine.

That's why we experiment and learn.

Bill - you are correct about sprint cars. Mini-sprint more so as they usually run on really short tracks.  They are built for quick acceleration off the turns.   Will have to research before I mod the air box.

Where are the underhead camshafts and pushrods?  Er, never mind.  I see you intend to go fast.

This worked well







Certainly got positive pressure even with the flexi hose
