400/4 low oil pressure + Other Misc problems

<< < (3/3)

K2-K6:
You can also make a small pocket of something like blue-tak if you want to soak it in penetrating oil...something like a kangaroo pouch type thing to leave it a while.

Mr-Gear:
Sorry for reviving an old thread,

FINALLY after a few months, I've got the bike home properly and took the exhaust off and front brake caliper.

Unfortunately during my first inspection I missed a bloody hole in the bottom of the silencer (Attached) and a single bent spoke on the front wheel (Does anyone here think that a single bent spoke on the front wheel is anything to worry about for the time being?).

The exhaust sounds like a maraca and after poking my finger through the hole a load of rust pours out... So I'm going to look at making a stainless exhaust in the near-ish future, probably not TOO difficult.

I took the caliper apart to find a fair bit or corrosion on the inside and the piston has some pretty bad pitting, after machining a new piston out of stainless bar stock to the dimensions of the old one, fitted it back together and bled the system however it doesn't feel like there is a great deal of power there, the lever can, with a bit of grip, touch the bars and the pads don't seem to reset properly (Slight bind). Am I over estimating the brakes power? or is this just how they are?

P.S: I changed the oil from the 20w50 stuff for halfords 15w40 and that has cleared up the clutch slip dramatically and also I believe it has solved the sticky gear change since I haven't encountered a problem yet. thanks for everyones advice on that.

Thanks, Ryan

my experience with the brake is the caliper seal hardens,causing some of the problems,it is the flex in the seal that retracts the piston,
they  are cheap as chips to replace,so try that ,and see how the brake is after,

Mr-Gear:
Thanks for your reply John, But I forgot to mention I have already replaced the seal  :-[, I'm gonna take it apart again tonight and try to clean it up a bit better.. maybe I missed a bit of corrosion somewhere
