hi im new to this site i have just bought myself a sinnis apache 125 and im looking to add some upgrades to it ive already found a molkt 26 mm carb power filter and im debating wether to buy it or not.

has anyone else done this and does the molkt 26mm carb fit straight to the standard inlet manifold or is it best to get another one.

i can do re-jetting if needed thats fairly straight forward ive also found a kamikaze k-pro cdi which i will be buying.

the one thing im wondering is about the exhaust ive seen that people have just fitted standard big bike exhausts does this affect the back pressure that the engine needs as ive been told these engines need some back pressure im abit of a noob to tuning bikes four stroke bikes.

in the past ive tuned a cagiva mito evo full de-ristriction pod filter new carb and race exhaust and expansion chamber

and also tuned a gillera runner 125 sp malossi 172 big bore kit malossi carb pod filter malossi gear up kit and pm tuning race pipe.

any help with the sinnis apache would be much apreciated thanks
