Dropping front forks
 
After fitting a Metal Mule lowering link I raised the front forks through the headstock by about 15mm but the result on handling is horrible.

So I've loosened the bolts to drop the front forks back again but easier said than done. Is there a technique?

you will need a block of wood to put on the edge of the top of the forks and tap it with a hammer to move them down again

You also need to take the weight of the front end - jack the bike up under the bashplate (or a centre stand if you have one) - leaving the front wheel in place can actually help, as it will pull the legs back through the yokes - make sure they don't go too far though!

I'm now wondering whether it really is the raised front forks that are giving the weird feelings.

It's as if the front tyre keeps getting caught in a rut and when I've been going straight for a while the effect when I turn is much worse.

The bike was fine before being serviced in Spain and I put it down to the MM links or the change I made. But could it be something to do with steering head/bearings?

Have you checked the tyre pressures?

I have the same links leave the forks where they were. Dropping them will make it turn quicker

leaving the forks as they are and lowering the rear will really slow the steering down.. not sure what the MM links are but I assume 35mm ??

I'd start off by lifting the forks through 5mm or so and take it from there.. small changes in fork height make HUGE chages to handling/steering

When I dropped my forks down it made my steering really unstable over 50mph, so I put them back to normal and stiffened the back suspension 2 clicks on the spring, and it works fine now for me, turns quick enough and no wobble on the steering at high speeds.

I think you have just got to try and see what works for you, and ONLY DO ONE CHANGE AT A TIME, or else you won't know what fixed it.

Thanks for the assistance, eventually found a cycle shop in Morocco and put the forks back to where they were. Things are much better.

On the positive side I had the side stand shortened and a bigger footprint plate welded to the bottom. Cost me the equivalent of �1.
