Yamiya No No. Exhaust Not Fitting Well

(1/5) > >>

Finnigan:
I purchased a 'lotus root' exhaust from Yamiya for Xmas despite the shipping and tariffs.  Gorgeous pieces and while the 1 and 2 pipes fit perfectly the number 3 pipe has issues,

- While fully seated on the exhaust flange(?) the pipe hits the rear axle and doesn't line up with the pillion hole
- The pipe's angle and position are noticeably different when compared to the #2 pipe
- The #3 and #4 pipe joining baffle seem to be at different positions

Yamiya sent a leaflet saying something like this can happen and to adjust the pipe by moving it out and up (I read that as 'lift it hard and even stress/flex to get it to fit') but not even close.  I put some rubber between the pipe and frame and tried to flex it but nothing seems to be helping get even close.  Standing back it looks to me like the compound angle is making it point out the back the of bike wrong.

I sent an email to Yamiya with no answer yet.

 If one side of the flange is tightened before the other, the copper crush washer can be uneven causing the flange to tip one way or another. I like to hang them loosely and start at the rear.
 That said I am one of the few that also had a line up challenge with a Yamiya no no. pipe. My most recent set of Yamiyas came with steel line-up tubes to go into the muffler connector at the rear.
  On one #4 I connected the rear and peg bracket then coerced the front onto the exhaust nipple with a rolled up towel and a rubber mallet. Be extremely careful if you proceed in this manner.
 The busso pipes required a ratchet strap and a little tug towards the rear. It looks like #3 is one way and #4 is the other way.

I have a long pry bar (about 3’) with a tapered end. I turned down the last 8” so that it just slips through the tube on the pipe. I use it to “pull/push” the pipes into place. Usually start with the inner one and then remove it and work on the outer….
Good luck
