Airbag vests.

Airbag vests.

Decent explanation of airbag vest types by the you-tube channel Fortnine.









You can’t put a price on your health but having never looked at them before all I can say is wow they are pricey for the latest models.



370 euro for the older helite model on fc moto site which I suppose isn’t too bad considering it replaces front/back and neck brace.



Not in the market for it atm but might suit some.

Weird noises K5 gsxr 1000

Weird noises K5 gsxr 1000

Was doing a “hard” pull from 2nd gear 100 km/h to 200 km/h and this noise suddenly appeared. I know these bikes come with automatic cam chain tensioners so why it would make such a noise if it is supposed to adjust itself automatically? The noise increases with RPMs and sometimes disappears at idle.



I am thinking it may be either the valves, rods or bearings or possibly cam chain. Anyway, someone maybe has experience with this and could recognize it from the sound. I have added a video of the sound during startup.

Mehole owes me a Yuasa

Mehole owes me a Yuasa

Bought a new battery after first lockdown, looks like I need another new one now. And before anyone says it, I don’t have private parking so can’t use a charger/tender. :doh:

Recomend me a machine shop nearby

Recomend me a machine shop nearby

Howdy,



Not a bike related post but the tools are the same. Can anyone recommend an engineering shop on Dublin southside – Sandyford area, that could drill two 12 mm holes and put a 45 degree bevel into a hard plastic? I could attack it with my Aldi cordless drill but I’ve only one shot at this and google is not being the most helpful. A bench drill, the correct bit and whatever is used to bevel a hole is all that is needed! A mate in the UK said he could do it in 60 seconds and that includes putting the drill bit in!



Any suggestions? thankyou :bikerie:

Bike testing

Painful if the bike has to be tested too. I think bikers here keep their bikes in good shape.

Tyre pressure – rule of thumbL hot v cold ?

Tyre pressure – rule of thumbL hot v cold ?

(Not sure if Ive asked this before, if I have apologies)



Read this a while back:



Bike Tyre Pressure Setting – 10% rule



MY manual recommends 32 PSI front solo. I run 36. I found this out by testing as follows:



Inflate tire to cold pressure.

Run the bike a minimum of 20 minutes.

Check hot pressure. It should increase 10%.

If its less you need less air.

If its more you need more air.



Do this in 2 lb increments.




I presume the pressure rise when hot comes from friction between the tyre and the road, and a degree of flexing of the carcass itself. Based on the above, it would look like you can gauge whether the tyre is working properly by the temp/pressure rise between cold and hot.



Does that ring true – could you use that to find out what pressures you should be running for your tyres, your own riding style and weight ?
