@landuse - Its definitely easier to "control" off the line or ripping straight through the yard. I was hoping I could muscle it to the inside of a turn for some dirt track style power slides but the weight and geometry is not right to lay get the rear to kick out for a good powerslide. (could try using the rear brake to set up a drift, I guess)
I am about ready to try a baseline lap time in my yard track.
I kinda doubt it will beat my 2019 Yard Kart build on the yard track, but the trike will roast the rear tire on pavement and wil be much faster where conditons permit as it has the big motor and a 6 speed gear box.
However, on the mechanical side, there is something going on with the engine during a cold start. It seems like it is taking a while to build up compression (?) to make power.
I put in new NGK plugs and upgraded the ignition coils to see if that would fix it, no joy yet.
It's a bit smoother and it will kick over immediately and warm up pretty quick if I use a shot of starting fluid in each of the carbs.
I did some searching around on the CBR Forum and a couple of folks there have said valve adjustment fixed their hard start issue, while others have no problems with cold start and they run theirs up to 25k miles with no service issues. This engine has just 17k miles on it, so it seems the PO may have not had it serviced before it got dumped.
We all had a mower or tractor
that would not start until the valves were set to spec, right ?
I will be checking the valves and cleaning up the hoses under the tank, will try a compression check before and after. Then try to balance the carbs.
Maybe then it will start and purr (or growl) like I want it to...
