Sand is better than nothing, however I remember seeing it done using lead, and that really worked great. Want to guess how long ago that was?  ;D

"Of all tyrannies, a tyranny sincerely exercised for the good of it's victim may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated, but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience." - C.S. Lewis

Couldn't get my cone layout app on the phone to do what I wanted, so took a lucky guess using the inner and outer of a roll of masking tape.  Lucky guess!





Need a bit of tidying before welding on a belt sander, which I don't have, but I like the overall shape.

Yes, going to have to rig up something temporary to get it through the test for the road, won't matter if it runs like crap for that 5 minutes each year

Every time I see unbaffled megaphones like that, I think of Lord Moonpie's racing exhaust on "Doctor D" Dave Hiller's 750F and Vincent's CR for the street.  Doctor D's can wake up half of Seattle with his pipes on the dyno.

Bit more mocking up today, need to bring the lower ones (upper in pic) in a bit I think.  Definitely not going to interfere with the wheel spindle

Are you sure those will not scrape when you lean the bike over?

Probably, this was just a mock up to see if they were any where close to being ok.  I'll be tweaking them further.

Tremendous work...would be just slightly even more tremendous with more upturn.  Ha ha turn up the up turn and they will be truly tremendous.

Thankyou, I do intend turning up the upturn, but am going to wait until after upturning the upturned bike to get the upturn correct

Very Nice. Are you able to change the oil without moving the pipes or are you going to install a remote filter and oil cooler?
What color scheme for your tank, etc, are you going for? 


(never mind on the oil filter...April Fools Day post shows it clearly...)

Those pipes look like they took some time to weld up.  I am not an exhaust expert but do the sharp bends at the exhaust port present any flow issues?  I like how tightly the tubes tuck on the bottom of the frame.

I'm no expert either!  But there is about 60mm straight pipe before the bends which are 3 x 30 degrees.  I'll be surprised if it runs at all after I'm finished!  Running well will be an added bonus
