We`re putting new fork seals on my step-sons bike tonight and I wondered what weight fork oil to use? I know the manuel says 10w30 engine oil but as this isn`t the most common of oils am hoping to put in staight fork oil. Any reccomendations on weight and make please. Thanks, Guy.

Thanks Ted I`ve some 10w40 in the garage so will use that. Spoke to a chap at Hagon shocks yesterday, didn`t realise how different fork and engine oil grades were. Also how the same weight oil varies from one manufacturer to another. I too have eaten a kebab or 2 too many over the years

Bugglier, forks apart and the r/h leg looks like one of fifes' bananas Did notice that they differ though. Pics shows fork legs as on bike, i.e left leg on left side. The reason for different oil quantites I guess.

the reason they put different mesures in each fork leg is because of the brake drum 136cc and 156cc in the other

So.....the leg with the spike at the bottom goes with the stanchion with the smallest hole in the bottom? And the leg with no spike and the flange for the drum brake goes with the stanchion with the bigger hole and has more oil in it? Is that right?

Just checking as that's how I assembled mine and it seems to jam a bit on the left hand fork(the one with the spike in it) I think the spike is getting stuck in the hole at the bottom of the stanchion. I've checked the fork straightness and it was OK.

Can someone help me - I feel a bit thick

BTW anyone in SE London who's going to the Bolney run? .........or can pop round for a few minutes advice on electrics.....there's a beer in it for you

NO THE DRUMBRAKE /SIDE TAKES MORE OIL THAN THE OTHER BECAUSE THERE IS MORE WIEGHT ON THE DRUM SIDE THAN THE OTHER DOES THIS HELP I CAN GIVE THE EXACT OIL MESSUREMENTS IF YOU NEED THEM
