| Post subject: | ZTL2 Conversion |
Hi was wondering if anybody can let me know what master cylinder they have used on a ZTL2 conversion to a 2005 XB12S? I was speaking to Pash and he was saying an 90s jap one may be ok with 5/8 bore i was wanting to keep the Original mirror mount just wondering what anybody has used. |

You could use one off an 1125 (I am guessing the XB12SX is the same), they are 19mm bore. That's what I use on the Firebolt. I stripped one of my ZTL2s last night and measured the pistons (I lead such an interesting life) and the mechanical advantage (area ratio) with a 5/8 bore is the same as that for the ZTL1 with a 1/2 bore. I will be trying a 5/8 bore next to see how it performs. The 96/97 tubers with PM calipers had 5/8 bore master cylinders. A lot of Jap stuff and Triumphs too with four piston calipers on twin discs. Worth having a look round dealers, bike parks etc. Note that bikes with twin disc sliding calipers generally use a 14mm bore. Recent Z1000 or ER6N have 5/8 bore and a hole for a mirror. |

Above, I am referring to master cylinders that look the same as standard items. You could get something with a remote reservoir off a naked sports bike. The bores are marked on the cylinders. |

Just fitted a 5/8" bore master cylinder (ex-97 S1) to the ZTL2 on the Uly. Pleased with it so far. I used: 2 x http://www.brakes4u.co.uk/itemdetail.asp?catid=2950 1 x http://www.brakes4u.co.uk/itemdetail.asp?catid=2926 We get a discount from them too... viewtopic.php?f=15&t=2160 |

Yeah man. I also used a Stanley knife blade to slice through the rubber grommets on the original hose so I could use them on the new one, with the clamps etc. |

Why would anyone want to add the massively heavier 8 pot caliper to an air cooled slug ?......thus negating any 'advantage' the ZTL might provide to unsprung weight

I found the 8pot to be a horrible wooden brake with little feel on the road and just unnecessary weight on the track. |
