All 2st Rebuild a pancake pipe?

Topped up the radiator put some fresh fuel in, put in a 40 pjet (had a 45)checked every nut and bolt that I had touched and all that I hadn't,t and took for a quick blast up the road.
All good started 3rd kick, bit high on the idle, way better response from down low, no midrange bog and no escaping smoke and power from the bent header.
So gotta get a chain for one of the kids 85 and we are hitting the forestry next Sunday for a bloody good clean out!!
brrrrrrrraaaaaaap!!

Wow what a huge difference a fitting pipe makes...
Actually held it wide open top gear for about 500 meters and it sounded friggen perfect., no lean pinging or nocking.
Happy days
Until I rode my mates 14 6days 300 and hit the same wide open section and clicked up to sixth gear and it pulled harder than a teenager. Honestly it has more power over the whole range.... And still on the mild pv springs
But he can only catch me on the flat open stuff.

Great to know. Thanks for sharing!
