DR 750 Big
« on: July 23, 2008, 02:49:19 pm »
We just bought a DR 750 big and need some advice on what pressure we put in the front forks and any idea why she wont start first time. We checked the battery which looks fine not sure where else to look.

I can write a book.

Check the valve clearance. Dont trust the manual its wrong. trust me. Me and my brother in law have got them.
I will check up on my notes what the correct clearance is. i had the same problem. I found the answer on the net. Not a guarantee solution but a good start.
Battery must also be super strong. Sometimes it will swing forever if its a little under power.
Also try holding the decomp lever in for a few swings before releasing it.

What do you mean by what pressure in the front forks?
Standard front forks use 10w oil but know of one with 5w in (to soft for me) depends on weight and setup. What do you wanna use it for? Whats your poison.

You can play with the springs as well but its up to you and the application.
Post a picture of the bike for us to see. :thumleft:

above post was supposed to say army not arm. :laughing4:

Raven you must lift the front wheel off the ground. Support under belly.

Then release the pressure in the shocks. This will equalize the pressures in the shocks.

As far as i know you should not have any pressure on the shocks because it will pop the fork seals.

P.S When you shut it down dont turn off by using the ignition key or on off swith. Compression will whip the piston back and stuff up the starter system (dont belive me check it out its a real "system")

Pull on the decomp lever and it will glide to a halt. The swith attached to the lever kills it and the decomp valve opens up for relaxed slow down.
My tip of the day.

As you will have noticed its got two spark plugs :o
Make sure they are both working lekker. :thumleft: If problems, back track. It can run kinda on one spark barely though.
That was my last tip for the day.
