Title: 80cc kit
Post by: fraserdredude on August 07, 2010, 10:23:53 AM

ok heres the thing. i nearly have enough money to buy a new 80cc kit for my bike. this is the kit http://www.adrenalin-pedstop.co.uk/p/AIRSAL-80cc-CYLINDER-KIT-FOR-C-1916.aspx (http://www.adrenalin-pedstop.co.uk/p/AIRSAL-80cc-CYLINDER-KIT-FOR-C-1916.aspx)

on the description it says no upjetting or modifications needed, one of my experienced friends who is fitting it says that you probably wont need to upjet but it would help. another inexperienced friend says you definately need to otherwise it could burn the piston. who is right?? and if i do need to upjet could anyone please advise me on the jets to buy?? thankyou.

I don't believe it.  You are increasing the size of the cyclinder...

More air = less fuels (by ratio) = running lean

Any time you do something to increase one side of the ration, you need to compensate on the other.


Its the only way to get more power.

not sure where to go for new jets yet.
