Ok so I have a linhai matrex and I wanna put in a 72cc kit. What size jet and rollers should I use? and if anyone could point me in the right direction of a good kit to buy that would be great.

You can also get a crate 80cc if 4T or 90cc if 2T that bolt right in .
Start by finding what jet size you have and try a size or two up . Rollers weigh them and go with 2 or 3 gram lighter will help take off , uphill and keep rpms up for topend .
Replace the fuel lines and fuel filter since some stock ones are junk . Replace sparkplug with a NGK iridium as its the best .
Do that first and see how it runs before buying a BBK

there is no set answer if you have a stock air box 80-85 main jet and for rollers try a couple different weights until your happy i have 6 grams and a 90main and open air filter and it runs great for me i also got trans kit and hp exhaust on my gy6 if it is 2t thats whole different story

I can tell you what Im using but your ideal set up may be different.
6 gram sliders, 1000lb torque spring and currently a #87 main jet. I change to #89 in the summer. I also live at 6000ft elevation.

Its a four stroke stock everything. I would do it myself with the help of my mechanic friends (i work at a dealership so there are plenty of people floating around that can help.) I like the link for it seems to have everything in a kit for a decent price .

thanks for the info peoples. now i got another question. what about clutch springs and a belt. if i were to put 6 or 7 gram rollers and an 88 jet without a 72cc bbk what rpm clutch springs would you recommend? and if i installed the bbk would it make a difference? and also should i get a different belt?

dont do a BBK
the rest of the drive chain
crank etc is not built for it
if u have to upgrade, get a crate engine
or better yet get a 150
