so ive had problems with the 49cc scoot for a while and found out the piston rings went so i figured seeing im taking it apart anyways might as well up grade so i got an ebay 100cc bbk and a uni intake. runs awesome BUT, when i go over 40mph it cuts out comes back cuts out comes back. now ive read were ppl have had to replace there gas lines cuz they would start to pinch and cut off fuel or am i in need of a bigger jet? the kit came with bigger jet or was that just sound like some ebay crap
NOOB ? now im still running the stock exhaust can this interfear as well?
[replyingto=thebeerguy]thebeerguy[/replyingto]100cc kits call for - jetting depending on your intake and exhaust setup. A free flow filter and performance exhaust calls for + usually. This also depends on your elevation and other factors etc.
Stock CDI units usually do have a rev limiter which will prevent you from hitting your top speed, you should try getting an unlimited CDI and see if that helps your speeds.
ok just put in a manual petcock still no change gunna check out the plug and see what it looks like if it looks like im running lean ill get a bigger jet then later get the new cdi. also i did put a new uni filter on and didnt really know what to do with the pcv and vacum lines and that valve on the exhaust . sorry i keep adding more to the problem
