whatsup guys, im garrett and im from socal. i had 2 cateyes before, my first one was a junker, i think i picked it up from craigslist for like 60 bucks. tinkered with it and barely got it running. i know very little about tuning or pocketbikes in general so when it died i gave up on that. 2 years later i found a pretty solid cateye on craigslist. that thing hauled some ***(compared to my first one). not sure of the mods but it went a little over 30. two days ago i picked up a x15. i show up its a little dusty, okay no big deal. it starts up no problem, then i see it smoking. one of the wires was exposed and grounded to the frame. okay i can fix that. the radiator has a little metal piece that holds it back from the front wheel, it was chopped so i had to rig it up with zip ties to hold it back from hitting the front wheel. i will weld it when i get the chance to use my friends dads. so the first day im riding it after i fix a loose wire in the ignition(soldered it back) and the radiator issue, im testing it out and the chain started to slap around. i think its because it was too loose and the fact that the guy put a smaller gear in the back so it was closer to the frame. it had pegs on it so i had to go to walmart to buy a lug wrench to fit in there. we tightened it up and it was running so smooth. okay, top speed test run right? so we go out to the street and my buddy is getting my rough speed next to me, around 50/55 (im 6'1 230 lbs) so after some crusing i head back to my house and about 200 feet i hear what sounds like me running out of gas. at first i look down, okay gas in the tank, then i realize i didnt put any fluid in the radiator, it had very little so i thought it just over heated. after getting it home, i pulled the line from the carb, it was getting gas, i pulled the plug and put some gas in then reinstalled the plug to see if it would fire up, nothing. there was some air escaping from the plug(when it was pulled, does this mean its not seized up) when i tried the electric starter for a second. then i checked to see if there was an arc from the plug, i didnt see anything. the guy who sold it to me said he changed the coil before so maybe it has some issues, idk. do you think the (ngk) sparkplug could go bad like that or do you think its the coil? there is a racing cdi but idk how that might affect a stock coil (im assuming he put the cheapest one he could find). basically, are there any ways to check if the coil went bad or if i just need a new plug. also its a cluster fk with wiring, im not using any accessories (lights gauges etc) are there any diagrams or ways i could rewire it for only the essential wires needed?
