Hey, ill give you a break down of my situation. After moving to Costa Rica I decided to get a bike for transportation - As a new rider I bought a 125cc 4 stroke motorcycle. The name is genesis, probobly none of you have heard of it because I cant even find it on the net! The roads are so dangerous here its close to suicide getting on a bike. My First accident destroyed the whole front end, impact was at about 110 km/h. The second accident did little damage, but involved clipping a horse at around 100 km/h and sliding down the highway..... yeah i know..... The problem is the mechanics here are HORRIBLE... they dont even know what a spark plug gapper is - now im ok with carborated engines however iv'e never worked on a bike before. Since the accidents the bike seems to be lacking power and "shudders" (loses power and then regains it) between 7-9000 rpm. The carborator on the bike is horrible, it comes factory set and is not possible to adjust, idle screw only. If anyone could PLEASE reccomend what problems i should be looking for, or any solotions, it would be greatly appreciated. Thanks! (and yes i clean the carborator often, as my dealer said it was neccesary when the bike is being used in constant full throttle)
