Jet
Powered YSR Motorcycle Getting
it all to fit and look right
Bike in full dress
I had to order a
new front fairing for the bike to replace the cracked one
that was on in the previous pictures. I was fortunate enough
to find one on Ebay (thanks Kevin!) and got it here right
away. There was also a ton of things to do to mount all of
the little doodads on the bike to make it even cooler.
Most of the pictures
are just of us getting the fit of the body right, but there
are a couple of new additions and some surprises too. Be
sure to check out the videos and see some of the goodies
we decided to throw in just for good measure.
Cleaning the tank
Firstly, since
John was here helping out I had him strip the tank to get
it ready for paint. There were numerous coats of old paint
that looked as if they were from various racing paint schemes.
John brought over a little poly abrasive wheel that would
just take the paint off super quick and leave a nice bare
metal finish.
Quick removal
I had never used
a wheel like this in the angle grinder before, but I am
a believer now! This thing wouldn't gunk up, slow down,
or give you grief. What it did do was take off the paint
really quick. You can see where he has already cleaned the
paint off the tank, and it leaves the metal nice and ready
to work with for Bondo and primer. Really cool tool!
Fitting everything together
With the tank
almost completely stripped, I put everything together for
a trial fit. There isn't a lot of explanation needed for
most of these pics, so I will keep it pretty short.
New dash panel
I fabricated
a new dash panel out of some diamond plate aluminum sheet.
The main switches, and control computer will mount up here.
Body fit with new engine mounts
I thought there
would be some minor trimming to do on the body panels once
I mounted up the engine in the new motor mounts. I was happy
to see that everything fit together good, and I don't think
there will be any need to go cutting away as the fit has
stayed the same for the most part.
CO2 tanks
I did manage
to get the mounts for the CO2 tanks on the rear swingarm.
Yes, I know this is a nitrous bottle, but no there won't
be any nitrous used on the bike. This just happens to be
the same bottle size as the CO2 bottles we will be using
for the cryogenic cooling system, and it was handy so it
was used for the fit up of the mounts. The CO2 tanks will
feed the intake cooing system, which will give us a bit
of a boost by allowing more intake air to be pulled in to
the engine. Basically, the colder air is more dense, so
the same size "bite" of air will actually have
more air in it than air at normal outside temperatures.
Looking like a jet bike
This thing is
looking more like a jet bike all the time. I do have to
admit, that the tank looks much better without all of that
caked on old black paint. Thanks John for doing the dirty
work of cleaning that stuff off!
Rear view
This view from
the back shows how the jet pipe will sit in relation to
the body panels. Also, you can see where the CO2 bottle
will mount on the other side. What is that strange looking
thing on the left side of the swingarm I wonder?
New fairing
The new front
fairing was a good find. It has never been wrecked, and
is almost ready for paint. I will have to get a front fairing
stabilizer to keep the windscreen from flopping around wildly
at high speed though.
New engine mount
Besides looking
really cool (as any bike with a jet engine in it would!),
this picture shows the new front engine mount. It is made
up from a stainless plate that has been laser cut to match
the compressor opening. The bolts pass through slots instead
of holes, and this way we can make small adjustments to
the angle at which the engine sits. Again, a big thanks
to Chris Krug for helping us with all of our laser cut parts!
Now that's a jet bike!
The bike looks
almost normal from the front now, and the only giveaway
that is readily apparent is the little bit of the combustion
chamber you can see in the lower left of the picture. I
love it when a plan comes together!
The dash
Here is a much
better shot of the dash. The cut out on the lower right
is where the master cylinder fits when making a left hand
turn. Looking at the far right of the dash, there is a small
black bolt that holds the dash to the front fairing stay.
Directly to the left of that bolt is the new key switch
for the bike. The computer screen will fit on the far left
of the dash.
The left side
This is just
the left side of the bike. I may still have to cut out more
of the fairing to clear the turbine, but I'm not sure as
I haven't tested for max heat output of the engine with
the new turbine heat shielding in place yet.
Another left side pic
Just another
left side pic of the bike, because I think it looks good.
What is this?
OK, for those
of you who didn't notice it already, that is an electric
motor mounted to the side of the swingarm. The question
is why? Well, this bike will be run at drag strips as an
exhibition vehicle, and there is a funny thing about drag
strips. They just don't really care for it when you drive
through the pit area with a jet engine spitting fire everywhere
out the tailpipes. So, this is the electric motivator to
get the job done of moving me back to my area in the pits.
It doesn't move the bike very fast with me on it. It will
also serve another very crucial purpose. If I take the bike
out on the street, the motivator will get me going at a
stop light instead of having to use the afterburner. I am
sure it will be very much appreciated by the car behind
me, as the blast from an afterburner tends to messy up the
paint on trailing vehicles just a bit! The motor is a small
1 horsepower electric motor like the type used for starters
on garden tractors.
Electric motivator tests. Push play to watch
Above is a video
of the tests of the electric motivator. Another really neat
thing about the small motor is that it can be used as a
regenerative braking system. This means that the faster
the bike is going, the more stopping force it creates. A
very nice thing to have, because the original rear brakes
on the bike are drum type, and not very big. The motor combined
with them will provide plenty of stopping power.
Clearance between body and engine
Just a picture
showing the clearance between the body and the engine. I
have a bit of room to fit things, but not much!
Clearance between body and engine
The same clearance
from the other side.
Turbine housing clearance
There is that
pesky issue of the turbine housing clearance. I really hate
to cut up the body panel here as it would remove a good
portion of the left side. If I have to I will, but I will
hold off for now.
Underside
There is good
clearance on all the parts, and the underside of the bike
looks great. That big exhaust really lets you know that
this bike means business too!
Jet pipe routing
Here is a great
shot where you can see how the pipe will fit over the rear
tire. There is also about 3 to 4 inches of clearance between
the pipe and the seat pan. Thank god for heat shielding
material or I would probably end up feeling like Yosemite
Sam screaming "my buns are burnin!".
Rear angle
I will have to
fiberglass in the openings on the rear body panel, and may
make the fiberglass work extend up under a bit for a more
finished appearance. I do know that since the room is there
I will be using the original battery box location under
the tail section for some extra room when mounting all the
sub-systems.
Random picture
Another random
picture. Hey, why not throw it in for good measure? At least
it shows another angle of the bike, and since I'm proud
of the work I want others to see it too.
Our sponsors banner
We are so proud
of our sponsors, and all of the help they give us on the
project. Thanks to all of them for standing behind us on
this crazy idea!
Speaking of sponsors
Another of our
sponsors, Kenda Tires. Thanks for the great set of rubber
the bike will roll on. Check out the next few pics to see
the tires they provided for the build.
The new rear tire
Here is the fat
rear tire we will be putting on the bike. These great tires
come in widths up to 140, and this one is a 130 that we
will be using. Then again, maybe we will use the 140 if
we feel like it!
Much wider
The 130 is already
much wider than the stock rear rubber on the bike. It will
really be more for looks than anything, but shouldn't a
jet powered bike look good too?
Plenty of tires
We have a few
different sizes of tires to play with, and to keep us on
the road and dragstrip.
Gogo button bracket
The little bracket
mounted on the left handlebar will be for the go-go button.
This will be the switch to light off the afterburner and
get things nice and toasty!
Key switch
And the key switch
to keep the neighbor kids from trying to take off on it!
Another random pic
Another picture
just because I think the lines of the bike look good. Hopefully
it is enjoyed by my site viewers as well.
The last one this time
The last picture
in the set. I just love the way that big exhaust sits under
the bike. You can see a lot of fabrication and modification
here. The extended swingarm, the jet pipe, the adjustable
rear struts, it just goes on and on. When you start a project
like this you don't expect there to be so many little things
to do, but there are always tons of them. Again, thanks
to my wife for putting up with me for all the hours I spend
in the shop doing work on the "never ending list of
little things".
Another engine test. Push play to watch
Finally for your
amusement and enjoyment, another engine test video. Take
a close look and you will see that right as the engine starts,
the camera guy jumps a bit and shakes the camera. I just
have to give John a hard time about that!!
Well, I hope
you have enjoyed seeing a bit of our progress, and what
the bike will look like. There is lots more to do, and many
pieces to fabricate. Hopefully it will all go very smoothly.
Thanks again to our great sponsors, and all the help they
give us. Please remember to help support the site, and be
on the lookout for more updates and more projects very soon!
