Well, here it is, start of another season of racing for us old farts!

Last year all of my tools had already been moved when I decided to build the Bonneville Bomber. That bike was put together with a 4 inch grinder, a 120 volt Lincoln mig welder, a 10 inch disc grinder and a benchtop drill press. Any special tools I had to make, buy or borrow to complete the job. SJBMW did my heads and everything else was done in my shop. With the help of my friends at AirTech, MDR, and Bob's Garage, including help from Scott, we got the job done
A lot of things were put together, knowing they would be changed this year as more time was found for construction. Here we are again, getting ready to race while I still have more on my plate than I have time to complete. I have the house and shop nearing completion and vines just delivered, ready to plant. Whew...what did I do when I had a full time job!!
Most of the tools are still packed, so I'm still working on a shoestring for the Maxton race on April 5-7. I do have more tools available than last year, so it will go a little quicker.

My goals are this year:

1. Add engine and gearbox oil breather/recovery tanks. Last year, after each run I had oil dripping from the engine breather tube onto the salt and the 90 degree gearbox was overflowing from the breather vent.

2. Add reverse cone to exhaust megaphone to reduce exhaust reversion.

3. Add Air/Fuel, RPM data logging system to record info from each run Last year I couldn't remember "or see" the indications for this info on each run.

4. Add an airbox and ram air tube for the carburetors

5. Try to stream line the bike more than last year

Item #5 is underway. I want to build a completely new airbox and intake system when I get the new Lectron Carbs. For the first Maxton race, I have set up a stock R100 airbox with an open filter body (removed the filter material). I opened the air intake tubes and fitted 1 1/2 inch stainless tubes in each side that are sealed with liquid plastic. I will attach 1 1/2 inch tubes on each side that lead to the front of the fairing.

For the first race this season, I will be using an old set of 38mm Mikuni VM round slide carbs. The TM flat slides I used in Bonneville and El Mirage were garbage. I had nothing but problems with them and one of them had already failed when I started the bike this year. I don't know where they are made now, but it must be some third world factory that has been sourced because of the low price and quality!!

The Lectrons and new airbox will be on by Bonneville.

The bike is ready to go. It's been lowered, air intake has been modified and new electronics have been installed. I modified the seat and moved the footpegs forward a couple of inches. It has new Mikuni carbs for this race, I will be looking forward to mounting the new Lectrons when I get them.
