Carb works great but you cant have a filter on it.
Got this kit from a YouTube video i watched going on a 459. It was definitely expensive but I thought it would be good quality compared to the Chinese ones. However i was mistaken. The carb works great but now i cant run it with a filter because the filter that came with the “kit” doesn’t fit because you need a adapter for it. No the “kit” does not come with said adapter. I had to order the adapter separate and when it showed up it wasn’t even the right size. So now i have to send this adapter back and Jerry rig something together to get this carb to work somehow. When it come with a air filter in the “kit” you would think you can use it without having to get extra parts. For $210 and it doesn’t come with all the parts needed to make it work is beyond me.

Mixed feelings.
Air filter sent does not fit well. Mikuni is 58MM and the air Filter is 63MM. I contacted them and their response was to tighten the clamp more.

It came scratch and without a throttle cable. Works but do wish it had a little throttle cable bracket on top of the carb

Having an issue with a running rich now I have to order jets in order to clean up the mixture of little bit following spark plugs so I’ve got some more work to do furthermore with the trouble I have ordering the mikuni throttle cable was a waste. The throttle response is much better after lowering the needle hopefully I will get it dialed the carb should come with more fuel line filter and some jets

I have tried a ton of different things. Different exhaust and setting on the carburetor and I still cannot get the engine to take gas without fouling the plugs. I have heavy carbon build up on the plug since installing this carberator. I think I’ll need to rejet to get this to actually run.

Not to sound dumb but Does this have a way to choke the carb with a cable
