UPDATED; want your cag engine quicker?

[peep108]

i have a mod that i don't think has been mentioned yet, if you drill out your fuel switch .5mm bigger then what it is already it will let more fuel it the motor which gives you more power. note it takes some tuning to get it right with the fuel air mixture

just reading through this thread and i saw about the 1 piston ring it works if u take the bottom ring off and leave the top ring on and i heard it gives a tad more compression aswell

if you mean the fuel tap i doubt this would help any with power as the jet in the carb meters the fuel in the end, so supplying any more or any less to the fuel bowl wouldnt really affect it.

but i drilled mine anyway just to help supply the float bowl with a bit more juice as assurance.

Cag was the 1st 'fun' produced mini moto by Cagllari.

China have produced 3 main, and very popular types of bike. Priced normally at under or around $200 $250 for the latest spec, these bikes are great value for money, and are a lot of fun to ride. Aimed at people who dont want to fork out hundreds for a race-ready mini moto has made these bikes a big hit amongst kids and adults alike. The basic Cag bikes can be used on a track, but not for proffesional racing. Cagclub.co.uk Bikes

quoted from this webpage have a read its a great bit of info Cagclub.co.uk Bikes

People occasionally ask how to tell if they should use an advance timing key. Unfortunately there is no easy answer as it depends on your crankshaft and flywheel. Both vary depending on which factories in China made them.

RD RACING posted this info a couple of years ago on checking your timing to determine if you should use an advance key or not.

Hope this helps out some people. I know I checked my timing after I read RD's post. And thanks to RD for sharing his knowledge and experience with us.

Stick a 6-port RD race engine in, with a Fatboy Exhaust kit, yeah!
