Gents ...
Anyone tried/has any experience with this configuration..Just looks a bit more'easy on the eye ' than the sort of 'dogs hind leg'... sticky out...kind of afterthought muffler set up that can spoil the looks of say a ...UCD .60...Dave.

YOU went with the os 91 not the ys 110fz Shame on you.....just kidding.... The tuned pipe will be allot quieter and adds some performance .....but not worth the money...just my 2cents ...JW

J...i'd allready got the os in stock... but being a sneeky little snake ....thought if i went horseriding (why anyone wants to do this is beyond me..?..! ) with the girls ,on MY birthday ..i'd get some bigtime brownie points... that get doubled on birthdays...so i could hit the director of finace for th YS later today..... i can here her now .... oh.. go on then if you must ... well thats the plan..!

That sound's very familier...Iv'e found that sometimes it's easier to ask for forgiveness then permission....lol...just kidding I think that you will have allot of fun with the UCD3D with any motor you put in it ...The YS 110fz will fit right into the same mount as the OS 91 fs ,so when you get the YS the swap will be very easy .....good luck and have fun ...JW ...Oya HAPPY BIRTHDAY.......

I emailed you about moving the engine from 5-7/8" to 6-1/8" ...I moved mine forword because the cowling didn't line up as per the manual.....I had to let you know of my error and I again must apologize for any problem's this may have caused you.....I will go away in shame now....JW
