Re: batavus high comp head jetting

You might have been better off investing in and exhaust rather than a high comp head.. as for your initial question well ride your ped and see how it feels and plug chop as well.

it rides fine but i cant seem to get`past 25....

Re: batavus high comp head jetting

To get past 25mph.

Raise the exhaust port timing.

These will give you more top end.

The cylinder needs .020-.040 removed plus the head.

Alot of mods for the battys must be done with on hands work no aftermarket parts buy MLM sells a sweet ass intake I thought. Ask Devin .. Its a shot in the dark.

Think those have been gone for a long time...make your own.
