I have been putting together a APS 250 using a Suzuki RGV chassis and a Aprilia RS250 90degree V twin 2 stroke engine (based on a RGV).

This is the original bike. Had planned to run in P/P 250 but a rule mix up changed my plans.




Team Two Short Men at the first meet at Lake Gairdner, ended up running it in M/G 250 in 2010 ran 119mph License Pass and had a miss fire on Record pass 99mph. (Me on the left with my brother Gary pit crew.)



Rain outs have left me with my plans a bit all over the place. But from there.

This was Mk2 at 2011 wash out. Hoping to push the record up a bit. Drank Jim Beam instead until the road re opened and we could head home.lol



2012 was always meant to be a move to APS bike. I'll have more soon.

Hey Pete,

good to see you here, get over to the "Introductions" thread and tell the family what your up to or the old man SSS will get huffy. Tell us where you're from in Aus, I seem to remember you're a crow-scoffer.

You started with the DLRA during a tough stretch, hang in there. cheers cheers

Been to Intro page March 30 I'm a Brisvegas Boy grin

The Trailer Panels held on with Sikaflex Body Adhesive and Riveted.

Had to make a few mods after the 2010 trip. Dust!!!

All good now with twice as many Rivets and a Vent in the roof.

Get new Trailer Pics soon.

Pete,
Nice looking bike!  Bet it sounds wicked too.  I ran an APS 125/2 for 3 events of the ECTA Mile.  It is a 1994 Honda RS125.  Not many 2 strokes out there any more.  Mine is now back to sitting in the corner of the shop while I work on my Morini 350. 
One suggestion- while on the rear stand practice your tuck position and have someone take side view pictures.  You may find that you can keep your head lower and still see forward if you place a high density 2" thick foam pad on your fuel tank.  The spot you want it is not for your chin but for the bottom front of the helmet.  You then have a target for your tuck position and when the helmet is resting on that you push down and it rotates the front of the helmet up.  That gives you a higher vision opening without bending your neck any more.  Helped me.
Good luck and always check those plugs after a run.

I have been doing the photo stuff from day 1 dr j.

The first thing i did with the APS build was work out where I sat on the bike and found I needed to extend the swing arm.



This the 125mm or 5 inch extension. I got this done as my ally welding is still a work in progress.



Then I worked out the seating position and made a subframe to mount the Seat.



An Ally tube frame gave me the shape for the Tail Fairing.



More stuff soon

Love that exhaust. It'll clear you sinuses as well as your ears.

Nobody will pit too close to you.

If you are running Nitro just hold your breath and don't have the earwax removed at your next physical.

Sorta like those divers that don't wear masks and harvest pearls.

You can do it.  The faster you go the less time you have to hold your breath.

It is nice to see another partial streamliner.  Will the shell be aluminum?

I have been building the bike over the last 18mths. So this is a catch up post.
I was not sure if I could put this thing together, but it has slowly worked out.

I have built it in Fibreglass.

I used 6mm Divinicell and heated, bent and hot glued sections to get the shape I wanted.



Then Glassed over it.



More soon

Are you going to leave the end of the tail open for the exhaust to get sucked out?

Love that exhaust. It'll clear you sinuses as well as your ears.

I disagree with Freud, as everybody will say they are "too close to you". grin
