Hi mini riders I have got some problems with my brand New pit bike from funbikes.co.uk in the uk.
Bike came already built up(PDI) btw!
So, first & foremost before first engine start removed the plug out(Denso...btw) was sooty black!! Banged in a fresh NGK cr7hsa plug ..then continued to kick the bike over a couple times on choke but no start so then I took choke off n kicked it and it started! I let it warm up for 10mins then took it out for its hour run in...that went all according to plan. Was feeling very happy until i came back to it hours later...the bike would not start at all...very unhappy at this point! So i decided to take the plug out to find the New plug all sooty black just like the Denso!?! Cleaned it up to looking all New again & refitted! Then the bike started...whoop whoop let it warm up,then done the oil change to New Silkolene comp 4 oil ( the best I'm advised ) started the bike again & let it sit for 10_15 mins then hit the kill switch! Job done!
The next day.... after a few tries the bike started,warmed it up as per then set off for a ride....INSTANTLY i noticed once shifting into 2nd gear about 1/4 to 2/4 on throttle the power disappears while backfiring & popping,nearly throwing me off the bike once power returns at half throttle all the way to fully open! This happens in every gear if the throttle is below the bog point!
I've called Funbikes about this and they say its a possible idle/air mixture adjustment needed so tried that no difference.... so before i call them back to vent my frustration at i would kindly ask for you're advice as to getting my bike running perfect!
Thanks
