Restricted?

[juancojones]

After much hassle finlly go the Sito Plus fitted to my PK80s.
Anyway, I'm told the elbow that came with it looks like the elbow for a 50 special. The elbow has what looks like an inner pipe as well, like an elbow within an elbow. Does this mean that it's restricted? The scooter is running, just much much slower than before, there's not too much there at the high end of the revs. It starts to accelerate through eac gear but just hits a flat spot in each gear where it wn't accelerate any more. I've no idea what a restricted scooter feels like so does this sound typical and I just need to change the elbow or does it sound like something else? It was surprisingly nippy before and now just plain slow.

Thanks for any help!

There's several different elbows for smallies so if you've got the wrong one for your bike you'll get into alsorts of trouble.

Can't remember an inner elbow on my 50 but that was over 20 years ago and I took the whole lot off and fitted a Shaft pipe.If it is as you say then it certainly will be restricted and probably why you've had so much hassle fitting it.

You want to order one of these.
