Bike prop

Hi,
What the score with a bike prop.
I'm using a fireblade and a live axle and no reverse.
Would I be right in saying it's a bearing nearer the engine end and a sliding bit near the diff end?
Anyone got any pics?
Anything else I need to know like where to get one and which bits to measure?
Cheers,
Pat...

Yup - bearing on the front section, slider on the rear

Bailey Morris have done a lot of BEC props so should be able to advise which bits need measuring before taking your order - probably around £200 for a standard one without a TRT

With IRS, though, the slider is on the front, right?

TRT = Torque Resilient(?) Tube, basically the front of the prop has one diameter tube, the rear is another diameter, the smaller tube is passed inside the larger at manufacturing time, and then the two are joined together with rubber a bit like a metalastic bush. This allows a bit of twist and shock absorbing in the propshaft and can help protect the gearbox a little, but Ive never run one with any of the blades and never had any issues with either driveline smoothness or gearbox reliability.

IRS, Im not sure, I cant think of a mechanical reason to have it at the back as the diff wont move like a live axle, but I prefer it at the back anyway because if the prop flange on the engine ever comes loose, if the slider is at the front then the flange can slide off the splines and the prop will smack the tunnel (and possibly your legs), and wont stop until the car stops. If it is rigid between the centre mount and the engine, the worse it does is come a little loose and vibrate, its noticable enough so that you investigate and fix it, but its very unlikley to come off unless the engine mounts etc are very flexible.

Yes, but your rear diff is fixed.
My live axle diff will move up and down.

Got me thinking now, with a live axle, which end should be sliding - surely the diff end???

Yep definitely diff end on a live axle, otherwise you'll be pulling / pushing the centre bearing every time the rear suspension compresses
