IT 200 forks
« on: January 14, 2019, 09:19:56 PM »
I have a question for the masses
 I have 2 IT 200N's and between them i have 3 sets of forks. I trick set of disk ones and two drum brake ones that also aren't 200 forks that are both combined with twin leading front drums. Now between the two drum sets there is a difference, the boss where the front axle goes through is 10mm further down the fork leg thank the other one, plus one set seems too good to be over 30 years old.
 So if anyone has any ideas what they may be off it would be a big help
 thanks

One set is IT490 for sure.

The other could be YZ490J but it's difficult to see the detail on my ancient phone screen.

Cheers,
Dave.

Are the lower axle caps a press fit on the fork outers?
Looks like one of them has slipped.
I would say 490, not sure YZ or IT though.

Cheers,
Steve.

I thought that to but the grey plastic protector is the correct length for the fork tube protrusion so it is how it was intended it seems

This is from the underside, some .slight differences there.
 Its reported that both have been interfered with so hopefully I will get them apart this week an have a look as well as check the spring rates

Well, i called into my mate's who is pro-moto suspension and pulled apart both sets. The grey ended ones looked ok, oil was a bit dirty and they had .41 springs. The black end ones looked ok inside, had .41 springs too and had emulators. So i put the emulators i the grey forks and put them back together to be used on the weekend and the other set went back together as spares. The plan is to order some .46 s[rings and put them in the grey ones as my forks for bike two.
 Find out how they go on the weekend
