Hi, everyone. Since making the changes to my GV125 (main jets, plug cap’s and coil’s) the bike is running well but feels like the breathing is restricted. Has anyone fitted a K&N or similar air filter to the GV125?
Can you show us when you get a chance what the center of the spark plugs look like ?
K&N doesn’t exist for the GV125, however, the panel filter & airbox flows enough air to power a 250cc. I wouldn’t worry too much here. The GV250 carby uses the same airbox. GV250 EFi Injected & Carby use the same air filter as the 125GV Carby.
Lets see the analysis of your plugs i’ll determine what’s going on in the piston chambers.
