I own a 1994 suzuki dr350 and i find the front suspension a little soft so i was wondering how you would go about hardening the suspension if its possible. There are screw like things at the top of each fork im not shure if those have anything to do with adjusting the front suspension.

I Think the DR gets oil to the rockers using an external line. Look for 3/16 line with banjo style fitting on the head or rocker box. the bolt for banjo fitting is hollow. Do not accidently install a standard bolt at banjo fitting . And do not over tighten Hollow bolts in banjo fittings.

now u sound like a smart mechanic so Im sure u can read a service manual-fixya hasum

Spring preload FR
To increase the spring preload and
thereby harden the suspension, turn
the adjusting bolt on each fork leg in direction
a. To decrease the spring preload
and thereby soften the
suspension, turn the adjusting bolt on
each fork leg in direction b
NOTE: _
Align the appropriate groove on the adjusting
mechanism with the top of the
front fork cap bolt.

damping, turn the adjusting screw on
each fork leg in direction a. To decrease
the rebound damping force and
thereby soften the rebound damping,
turn the adjusting screw on each fork
leg in direction b.

Compression damping force
To increase the compression damping

on each fork leg in direction a. To decrease
the compression damping force
and thereby soften the compression
damping, turn the adjusting screw on
each fork leg in direction b.

Although the total number of clicks of a
damping force adjusting mechanism
may not exactly match the above specifications
due to small differences in
production, the actual number of clicks
always represents the entire adjusting
range. To obtain a precise adjustment,
it would be advisable to check the number
of clicks of each damping force adjusting
mechanism and to modify the
specifications as necessary

Whole process where need to turn toward "a" means clockwise and "b" counterclockwise. From Yamaha service manual. Hope this is good enough info to help you out. Good?

all good spiers,

the year model have not changed, even the rear wheel axle size is the same.

i dont think you can......because these bikes are made for confort at a cheap price..........

higher value bikes can be adjusted....they have special shocks and you can adjust on either soft or stiff ride.....

I need a manual or specs how to set the timing on a 93 Suzuki King Quad 300 ATV. Timing chain broke, bought a new one, jumped time. Need help.

I had the same problem. It was a blown fuse located right in front of the battery.
