Everyone is right…lol. Firstly. Had the opportunity to run it around and once it burped and started to bog I turned on the headlight and started to run fine…thank god for that one…I’d never would have figured that one out. That’s why this forum is so essential…we have the opportunity to learn from others hardships who have gone through the agony. Secondly. I used an unlit propane torch to test for a manifold leak and it kicked so I investigated that next…turns out the intake manifold was cracked! Gooped that all up with gasket maker for the time being. Hesitant to buy Amazon products and wonder if best to buy a used original piece…(had bought an Amazon maintenance kit…air filter, plug, whatever else…and the air filter came apart and allowed dirt into the carb/motor. Went back to a cleaned original. So in other words you have to be careful what buy from Amazon). Thirdly, haven’t checked yet but will check the inlet valve lash…since it still doesn’t start the way I’d like…but it is an older bike and all. thanks to all who have read and future enthusiasts who will need to read…lol.

Definitely that intake manifold is suspect especially with hard starting combination…I’ll test with some carb cleaner and see if revs up…thanks

Wow, thanks for all the help with this…I’ll get busy next weekend and let everybody know how it goes.

I’ve tried posting two replies and they just disappear… I’ll try again…thought I had it with the last carb clean but it burped and started to have same symptoms. Sits and idles reasonably but bogs as soon as try to give it gas. So I tried the headlight trick and it appears to help…ran fine without headlights on the other day so I imagine it depends on when it overcharges. Is it worth changing that part? Or just flick on lights when burps again? Now it’s having a hard time starting though…cleaned plug, bluish spark, so definitely fuel related…stupid thing is once it does start it runs reasonable and has no issue restarting…

So I fully choke and it starts reasonably. Runs ok and throttles up ok when choked. -2 Celsius here btw. Once I warmed up a bit and take off choke…idles ok but bogs when move the throttle off idle…checked fuel pump and and is getting good fuel pressure. I now am gonna take carb off again and reinspect/clean but blew with compressed air and cleaned with carb cleaner before…certain jets of carb should look at better? Diaphragm/needle looks good too. took apart carb again and physically removed jets rather than blow just compressed air…think I got it. Found bit of crap and then blew. Going to put a small new fuel filter on the vent hoses to see if prevents anything going in to carb…thanks guys think next I’d like to adjust valves…

Just started to bog in gear. Chineses carb. Taken apart and cleaned. Starts good, runs good, throttles good sitting there but as soon as try to go it will bog. Plug is black so I cleaned and adjusted needle downwards. Kinda lost at this point…ideas? Thanks in advance.
