I've been on here for quite a few years Dennis, just not been on for quite a while due to the Drag Racing.
I met Tiny on here when he built his 175 DOHC CB125 postie bike. 8-) 8-) 8-) 8-)

That is one nice video that gives me a big smile.  Brings back memories from warm and distant days when I thrashed the life out of my 305 superhawk.  No wobbles in the corners!

People say is is hot where you are.  Here is a picture to look at to cool you down.  A "tit stiffener of a day" as we say here.  Stay safe.
Now were even Bo. your "cool" pic gave me a long awaited cool change, glad the megga rev video link worked to warm you up.

To Sam and All.......YES :-) :-) :-) :-)

My team is ready and we are now preparing the new motor and adding some partial streamlining to the Triumph Cub. I am always on a tight budget and did not have the new motor ready, so we skipped last year. I hope to begin posting some updates in a few weeks.

Oh Tiny Noooooooooo!  I am so sorry to hear that.  I was really rooting for you with that way cool Honda 250.  I wish I was closer so I could come look at it with you after the meet to do an autopsy.  Thanks for the video post.  Awesome sounding 250cc engine until the extra noises started.

I think I may have had a crater in #4 piston before I left home,,from when I burned a plug earth strap during a sorting run, making that piston the sacrificial lamb ?
I sort of hope there will be a hole in 2 or 3 as well when I pull the head (damn near impossible to get those plugs out) , although it is not running lean,,it gets a failrly hot thing happening in the combustion chamber.
Although I have an EGT gauge , i decided not to fit it to the bike,,'cos they slow you down,,lol
