I'll try to upjetting and see how that works, but I think I'm leaning towards a new kit. It's expensive and I wish I could get this running, but eventually I want to have a solid ped!
I really don't think carbs are super difficult to tune, the bing 15 was a combination of main jet and c clip setting. It wasn't great when trying to start, which left me stranded once or twice (wet plug) so I bought the mikuni.
There's definitely something with the fuel not all being burnt. I just don't know if it's lack of compression, lack of air, or improper tuning but with everything I've tried, I haven't been able to break 37.
Has anyone else run into this issue with a treats kit?
