341 repo exhaust fitting issues.

<< < (2/4) > >>

flatfour:
My CB750 K2 is fitted with the DS pipes and the top one is much tighter into the frame than shown on your second picture.

Hi, thanks for the replies. I'd just like to explain the reason for starting the thread.
Long story short: Bought set of pipes of DSS, had a few problems with fitting.
Both left sides needing levering into place, when managed to get bolt through and tightened up balance pipes miss-aligned (a lot)and side stand hitting upper.
Right side lower fitted perfectly, upper way off, impossible to fit with lower in place.
I spoke to DSS and they offered to send me another right upper and see if it was any better, and if not satisfied send everything back for a refund...fair enough.
The replacement arrived today but unfortunately still no good as the balance pipes are fouling, preventing the upper from being fitted.
So unfortunately i'm going to be asking for a re-fund as they have no sets left.
Anyway...having 2 upper rights in my possession i made some interesting observations.

1, The headers are a completely different profile. One having a much more of a sweeping lower curve than the other.
2, The bosses that the bolt passes through sit at different heights.
3, The balance pipes are different lengths
4, There are visible spot welds on one and not on the other.
5, The seams are visibly different.
6, The drain holes are different.

There's no way these two exhausts were made with the same tooling, which would suggest there is more than one company producing them. Apologies if this is common knowledge for you lot in the know...I'm a complete newcomer to these bikes.
Be interested to hear others thoughts on the subject, especially now i'm back in the market for a set.
Where do i go now? CSMNL....Yamiya....?
Cheers

Nurse Julie:
David Silver sells off the cast offs / rejects from CMSNL.
Edit....Trig has just pulled me up on this. It is Coastal Path that sells all of CMSNL's returns or rejects. Silver has nit got anyone to sell his rejects, so, if he gets anything returned, they are either sold at shows or, put back on the shelf and then sent out to the next customer who orders a set. So basically, he puts exhausts that don't fit back in to stock and keeps sending them out until someone perseveres and makes them fit.

BigAl (Alan):
Just had a look at my K4, your ‘side stand stop’ on the lower exhaust has not been welded in the correct place. You do however, have the correct side stand for a K5

You are not alone with this problem, here is my experience with David Silver exhausts. http://www.sohc.co.uk/index.php/topic,16403.msg137927.html#msg137927
Eventually got a set from CMS, they did fit with some forcing but i am not happy with the down pipe bend.
