Hi im new to the forum so hi to everyone

I was just wondering, I have a ybr125 2006 model, it misfires/backfires on start up and sometimes when riding, upshifting and down shifting gears.

I was just wondering if this is normal, or what is the causes and fixes for it.

Also 80% of the time i have to use choke to start this bike, its very hard to start from cold, i was just wondering if anyone else has this problem.

finally This is just a general question, I like to look after my bike but im inexpirenced, i was wondering how to keep the bike starting first time

Check the spark plug is clean should be light brown on contacts check plug gap and HT lead is pushed fully on

Check valve clearances

Timing cannot be adjusted

Is this an Injection model or with carburettor?

Backfires can be caused by loose exhaust fitting or rusty / perforated exhausts.

Hey guys, anyone got a photo of YBR125's brake pads? i heard it's similar to sniper135. Just wanna check.

This topic was about backfire...why are you asking about brake pads? why not start your own?
