I asked this same question in chit chat very recently and it seems theyre ok going by the comments. I only asked on behalf of someone local not a lcgb member who is rebuilding a DL 200 wanting to keep it original looking.
Hi All, An update on my Scootopia SH22 carb. I changed the jets, but i left the 200 cc slide on. Remember I am now using a 175 top end, opposed to the 150cc top end, and a sterling type expansion exhaust, now running great. I fully recommend this carb. Happy days. Cheers Stag
