Lets see. I need to find the way to the journal function but I can say the expansion in on and it is welded. So far with me being a heavy guy and having the new rear de-railer I went to the highest ( smallest rear sprocket ) and put all I had into it as I accelerated with the gas after the pipe was on and the engine warmed up. It wasn't too dramatic but the front forks fully extended and I believe I had an inch or two off the ground for a moment or two. The sound is more throaty, the putt-putt of between 8 and 16 mph is easy so there is more low range there. The comfort zone of 20-22 is now 23-24 or so. Now There is still airflow issues and I plan to try something to fix that so long runs in open country on a hot summer's day like this week is will not heat the motor to diesel-ing. Tonight in about an hour or so I will hit that back roads and see how she likes a long cool run. I have some pictures and I attached one. My friend Dale did well to put up with me and get most of the work done with me chattering on all day. Lets see if the attachment works.
