Bottom end power.

Hi, I am building a trials Bantam using a 4 spd B175 engine bored to 185, I will be using electronic ignition etc. I have been told that to obtain more bottom end I need to have the transfer ports "worked on". Does anyone have any info/ spec on what I need to get done, or any other tips??. I am building the engine myself but will pass the barrel to someone else to sort out. I will be using a Delorto carb or may be Mikuni?? Thanks in advance

Sorry Andy I don't think anyone on here can be much help..

Try Rex Caunt Racing he used to market Alloy D10 cylinders for trails use.

Hi Andy

Rex Gaunt still makes, barrels and heads and provides pistons in fact he can provide you with a complete top end, he also does ignitions and he is well known in the trials /MX Bantam arena.

We are meeting him on the 28th December at the sugarbrook Pub on the A38 from 11.30 onwards just off Junction 1 of the M42 there are a number of Bantam racers bringing bikes and bits and pieces to look at, you are welcome to come along and take a look, Rex is comming to and he is bringing some barrels and bits and pieces with him.

regards Derek
