I just put a boss tecno on my puch maxi and have a dellorto 15 mm with the stock air filter no cover. I had a 68 jet in the carb with stock exhaust and it ran good. I tried the pipe and it won't start then tried a seventy jet. still no dice. I need to buy more jets. I have a 69 what way should I try going? thanks
I have a high flow filter & a 72 on my 15 with the boss.
Its on a kstar 70, & alittle lean.
So perhaps 69-72 is good for you.
You should be going up from 68 ("upjetting"). Are you choking it when you try to start it? And have you checked for air leaks?
up is what I figured. I'm gonna try to open the 70 up with a torch tip cleaner and I think it may need some grinding on the pipe flange. thanks
I'm running the Kstar 50cc with 15mm dellorto & 70 jet. 72 jet and I four stroke a bit. I had the techno boss pipe on there but just switch to a biturbo. hitting 45+
You might be restricting too much air with the stock dellorto filter. Remove it and see if it'll start. I too run the stock filter, but I removed most of the screens from it.
Upjet jessu! fuckin g c!1
