Hello,
I have a yamaha jog 2010 with only 600km on clock. I have had a 70cc big bore kit put in, a new datona racing cdi(un restricted), new exhaust all installed with the aim to get it up to 70km/h(to keep up with trafic). All of which i have had no joy. It would do a maximum of 60km/h(tops). It had a lack of power. That is until the other day i got on and kick started it, as it was having trouble starting(cold morning). Once I got it going it flew, with heaps of acceleration and max speed of 70 to 80km/h. Loved it. This was what I expected with putting all the extra modifications on. It went really well for two trips and now it is back to no power and only getting 60km/h tops.
I guess the question is does any one know why out of no where I got my power and how do I get it back? Could it be the air filter or something else??? Apparently it does not have a fuel filter.
Any help/suggestions would be of great help.
Steve
