To keep myself sane during lockdown, I've set about working on my battered Venom 125 to get it vaguely roadworthy. Bought it off a insurance company with a few scrapes for next to nothing, so my expectations were surpassed when it arrived as it's way above the previous crud i've owned.

Been through most of the bike, changed the chain, new shift linkage and a good fettle of the electrics. Had the carb out when I got it, ran it through with carb cleaner, had the jets out and drained and replaced the fuel as I wasn't sure when it was last run.

Long story short, it runs like a dog, requires choke long after it's up to temparature and it bogs in any gear above 2nd with even the lightest touch of the throttle.

Has anyone on here upgraded the carb to something more reliable and if so do you have any recommendations? I'm 99% sure it's the carb, and i'm pretty sure it's all clear and set up as best as my limited capabilites allow.

Cheers in advance

Chris
