Post by: My_Lil_Kymco on April 03, 2017, 06:44:55 PM: Wanted to confirm it's working and not at fault as I'm checking the whole ignition system as I can't adjust the timing.

I think my idle jet is still low, is there a formula or anyone have a 70cc malossi on a 14mm carb as reference for jet sizes

Post by: paceneedsstides on April 04, 2017, 04:13:54 PM: Leo Vince Handmade ZX I'm assuming with that setup you should definitely work on upjetting big time and or getting a bigger carb also have to play with roller weights to stay in the right RPM range

Post by: My_Lil_Kymco on April 05, 2017, 09:32:56 AM: Yes, Leo vince zx, exactly!
I put rollers in that came with the exhaust.
As supplier didn't have jets, to get me outa trouble I drilled out main jet to 1mm, allowing for wobble I'd say it's 1.1m min. The idle jet is still standard.
I did order jets from uk but never arrived!
Will reorder again and keep fingers crossed.
Sorry pace, I didn't write full info last night, had a call out on a fault I had to attend.
But I see your on the 49cc forum and the Kymco too and see your replies on both.
In the 49cc I'm sure you saw my previous posts when it started to soft seize and I rebuilt engine before, well there is all the back story.

Rev range, since I changed rollers it improved dramatically, until the recent event lol.

I plan to get new piston etc thurs/Friday.
And rebuild it Friday evening.
Have to sit with current drilled out main jet and standard idle till the new jets arrive from the uk.

What carb would you recommend, or what jet sizes?

Thanks for your help

Post by: paceneedsstides on April 08, 2017, 06:33:06 AM: I would hget 19mm Dellorto carb or 19mm carb that has alot of parts out there it's easy for me to find parts for Dellortos so thats what I use on an open filter and exhaust on same performance scale as yours I was running 92-96 jet depending on temperature a CHT really helps oyu to tell when you're jetted right as it tell you head temp at WOT
