bantworm Posted December 15, 2007 Report Share Posted December 15, 2007 Hi. Does anyone have a detailed dimensioned diagram for the building of a silencer box for a Bantam B175 trials, using a standard large bore high level front pipe. I have seen a number of nice examples on classic trials websites, but would appreciate help, as I cant find much in the way of trials mods available for the humble Bantam. I would also appreciate a few pointers regarding gearing for the B175 box. Managed to find an 11t front final drive sprocket and a 58t rear but I have heard that it is a good idea to swap 2nd and 3rd gears round before re-assembly of the box takes place. Its all a tad confusing and I'd like to sort the engine next. Hope someone can assist with these questions. Cheers. Quote Link to comment Share on other sites More sharing options...
bantworm Posted December 23, 2007 Author Report Share Posted December 23, 2007 Seems the humble Bantam is considerably more humble that I first thought. Should have stuck to my Bullets, but I am a Bantamite too. I bought an adapted bantam sports standard silencer recently, and I'm going to adapt it a bit more before re-chroming, then run it high with an up and over front pipe i'm fabricating. As for the gearing on my B175 donk, I had some very useful advice from RCR Villiers in Atherstone, who well be rebuilding my crank, so sorted a few things out. Enjoying the forum.

charlie prescott Posted December 23, 2007 Report Share Posted December 23, 2007 Hi Guy's Hi Bant-etc, If you are going to use a road bantam silencer, for your bike you may find that the baffles are to good , this will restrict the bikes top end ,mostly when doing long climb's the works "Red T1" and "Red T2". used these to start with, but then fitted PECO type boxes. I think Mick Bower's always used this type. hope this help's a bit. Best Wishes for Xmas and New Year. Regard's Charlie. Quote Link to comment Share on other sites More sharing options...
bantworm Posted December 23, 2007 Author Report Share Posted December 23, 2007 Thanks Charlie, I appreciate the information regarding the baffles. I had wanted to use a box type silencer but was not sure if the 4 stroke items available would do the job. Was concerned about the lack of back pressure and the inability to pack the thing a little. Kind regards. Steve. Quote Link to comment Share on other sites More sharing options...
