WR400 99 manual owners, need some data

In "mm" please, just correct red data if wrong

1.

manual, page around 4-44 (cylinder and piston)

-cylinder bore "C" = 92.00~92.01 mm

-taper limit "T" = 0.05 mm

-out of round "R" = 0.05 mm

-piston size "P" = 91.945~91.960 mm

2.

next page, or 4-45

-piston to cylinder clearance = 0.040~0.065 mm; Limit 0.1 mm

piston ring side clearance

-top ring = 0.030~0.065 mm; Limit 0,12 mm

-2nd ring = 0.020~0.055; Limit 0.12 mm

3.

page 4-46

ring end gap

-top ring = 0.20~0.35; Limit 0.60 mm

-2nd ring = 0.40~0.55; Limit 0.90 mm

-oil ring 0.20~0.50 mm

4.

page 4-47

piston pin to piston

-piston pin outside diameter = 17.991~18.000

-piston inside diameter = 18.004~18.015

-piston pin to piston clearance = 0.004~0.024; Limit 0.07 mm

30 numbers overall, hope its not too much to ask.

I do have manual, but for past 2000 WR 400&426, so manual pages could differ.

Thanx

Cheers, Denis

Could make it blue, but...

Yes, nice link, only YZ 400's are available, probably data I search is comparable :thumbsup:

Denis,

I added in blue what my manual has for 1999. I only see a few differences, and they are service limits.

Thanks, you've just made my day.

Thankfully, data for YZ 400 '98 has the same diffrences as you've pointed out, so it is OK to use the link from Kepy.

Thnx again :thumbsup:

Hello, would again need data, this time on the fork oil level (from top with spring removed) and standard comp & rebound setting for the euro model bike.

thnx

Denis

oil level- 125mm

compression - 8 clicks out

rebound - 10 clicks out

Accepted :thumbsup:

Again, some data needed for the 99 WR euro model.

Extent of adjustment for the rear shock spring.

98 model 247-260 mm, 00 model 247-260, 02 model 240-260

99 model-???

and also standard spring colour (grey??)

Book page is 5-62

Also if there is any online manual for the 99, Id be glad to be informed of it.

All other than 99 can be found.

99 400 model owners, still need upper post data.

Its not, have 98, 00 and 02, all diffrent.
