Hello everyone just wanted to introduce myself as I am new to the forum and although I’ve had many years experience in the mechanical field with being a licensed mechanic for over 35 years it’s always a great asset to come into these forms to see if others have had situations similar to mine and gain some helpful insite from others.

so with that said not sure if anybody could point me in the direction of a unit been working on for friend it’s one of those Chinese ATVs i’ve not had much experience with wrenching on And after doing all of the standard checks and processes of illumination with This particular model a 2008 JAINSHE 400 mountain lion and the issue that I’m having is mid throttle backfire suspect ignition timing at this point but
thought I join the site to see if anybody has had experience with one of these in the particular has experienced this type of issue there’s not much posted on the Internet for these offshore Atvs. Parts or service wise so perhaps somebody out there can provider some much appreciated Insite.
Kind
regards
STN
