Welcome to the forum djrosa!

Most 150's use a #428 chain.. Not sure about the Roketa.. do you have a manual? It should list the chain size..

 

hey, don't buy the chain from an independant dealer unless you want to pay out of the nose for it. i've found that farm and ranch supply places, such as a tractor supply for ranching/farming and etc... carry the chains, master links, half links, and pretty much every chain size there is to offer. the local dealer here wanted $10.00 for a master link and 7.00 for a half link. i went to a tractor supply place and got both for $4.00. yeah, go figure!!!! hope this helps on supply. but yes, the manual should tell you what size chain it is unless you have some and then a supply house can tell you the size....

 

Sometimes it's stamped on the chain.
FYI: if it is 428, #40 chain fits 428 sprockets (same pitch) and rolls 10x easier.
Like mentioned, tractor supply or mscdirect.com

 

found out its a 520 54 link chain, now looking for a for a sprocket set, I can find the primary sprocket around, but no luck with the secondary one. I will have to get a tooth count on those yet, but storms in the forecast so I may have to wait them out to crawl under it again. Looks like I will need brake shoes as well. It does have a new carb, and the oil was fresh and full, new fuel filter and solenoid as well. Looks like everyone sells the tensioner, but holding off on that until I see how badly stretched the chain is. It was skipping teeth under load, so I cranked the tensioner all the way up, seems better but now its very hard to shift.
