If you look closely at the Lotus Roots, you will notice that they are very poor quality because the upper and lower welds are very poorly made and really look like lace... I think they do not control anything and they do not care... This is unacceptable >:(


i have only seen the LR's of Yamiya's first (2005) production run.  i have not seen any of Yamiya's later LR production runs to know if the first run is better quality than later runs.  i remember comparing my "05's" to 3 original LR's and being pleased except for the fact original LR baffles will not fit Yamiya mufflers.  maybe i do not have a fully discerning eye.

Just compare the photo of the LR with that of the HM300, and if you observe you see that the welding edges are very irregular and very unsightly in comparison to the 300...The flat connection is wide in some places it is very reduced in other places because it is eaten by the welding, I think that on the LR, the edge should be it seems to me 2 mm but regularly and there we are very far...
In fact the price is surreal in comparison to the quality, and they should be much more attentive, knowing that they are true sandcast specialists who will buy their bad LR copies, it's still a pity and very regrettable...
The first fabrications of LR were of better quality and very close to that of 300...
And If someone wants to send the link of my post to Yamiya I agree, because I have already contacted them but never had an answer from them...

How is my good friend from France with whom I will disagree. The original Lotus Root exhaust also had rough welded edges and nothing like the HM300 posted. I'll post a photo of an original when I get a chance.
If Yamiya has done one thing right it was to reproduce the LR exhaust and the no number exhaust. The HM300, as I understand, was never fitted to a Sandcast and for me is the same as using a Yamiya exhaust

I do not know very well the first sandcast, because we have that very little in France with the 74 California bikes of August 1969 and all that I know I learned from you on this forum, I I have a lot of gratitude for that, and I thank you for it...:)
Kp ;) but you have the right... And I can not wait to see your pictures of your LR my friend from Australia...
I'm like St Thomas who only believe what he sees...;D ;D lol

But not long ago, it seems to me that one member said that HM300 had aslo equipped the Sandcasts...
Where I'm wrong again?

No sorry, I found the post and Kp said they were also mounted on the K0 ... Important nuance!

Brothers, I love you all so much.
Photos as promised. The hits I take for the team. My sandcast F28 has been in storage for about 8 months and since my move to a new place is parked up the back and not easily accessed so best photos I can take. I really do need to haul it out and get on with a sympathetic resto.

Yes KP, I can understand what you mean for welding, but very honestly your LR have nothing to do with Yamiya LR repros...  What is a fact that an LR is an LR?  The famous solder of 2 mm very regular, and on your LR it is perfect with just what minor defects that I consider acceptable and normal, and on copies Yamiya it is a disaster !!
Your LR genuine, I will not hesitate to buy them if you sell them ;D ;D :D ;)

Conclusion : Why make quality if we can make shit that sells too? ??? ??? ???
