HI everybody,I have a 87 Hurricane 1000 and would like to know how
to adjust the front forks,Thanks.

 

Forks are not adjustable, other than by changing the amount or weight of the fork oil, at least on third gen (93 and up) bikes. OK. Just checked the parts fische, and it looks like the 87's have an air valve on the forks, which means you can adjust the air pressure in them. Increasing the air pressure should firm up the front end, just don't go down to the local gas station to use their air pump. You'll surely blow your seals if you do. A bicycle air pump should do. The Haynes manual say 0 to 6 psi pressure. The Haynes and Honda shop manuals can be downloaded at http://cid-f661f6844a8cd45e.skydrive...e.aspx/.Public

 

The forks on my 93 were'nt to good over pot holes etc so earlier this year i changed JUST the oil.
Now MUCH better.


ALL DONE

When i read the manual PROPERLY it is 14.7 fl oz per leg.
So after the oil drained overnight i took the springs out & measured them 446mm so all OK for now.




I measured out & refilled with AFT.




When i had done this i measured how much old oil had come out it was only 23 fl oz so 5 fl oz short, should feel a bit better on the bumps now.

 

NO oil just air?My only issue is on a good road no problems very good ride
but on the bumpy not very good.

 

Casino,

Here the trick, you need th oil in your fork , but can adjust it with a bit of air, although you can have up to 6psi of pressure, please don't go over 3 psi, on mine it is just perfect , you can use a small compressor where you can dial the amount of air pressure being pushed out, they sell them at Canadian tire, I got mine at 50% at 49.99.


Have a good day!

 

You can change spring pre-load in the early forks but you have to pop the caps and put a different spacer on top the spring. Bit of a pita but do-able.

Based on personal experience I totally agree with MadHattr059 & Dadarob approach, forget putting air in, it's a crap medium to say the least for suspension.

As mentioned above in the other replys, definitely replace the fork with 10W ATF fluid, you can add extra fluid to suit your ride 5-10% extra to each leg. I have an extra 10% in mine.

I also changed my spacers for longer ones made from stainless tubing cut by my local engineering firm so they were cut straight, total cost 'next to nothing'. They are only 15mm longer but makes a big difference to how the front end performs along with the extra oil and the 10W ATF oil used.

Adding air to the front end only loads up the fork seals, don't do it. Based on personal experience it's worth changing the spacers, the oil and mucking about with adding slightly more oil, it's well worth the time spent and cheap to do. If you want to spend some money, splash out on progressive springs, if they are availiable.

Cheers, Andy

 

When I bought my bike used the forks didn't work worth a crap. They were too soft, and had little to know dampening. I cut one inch off the spring and replaces it with a one inch spacer made of schedule 40 pvc the same diameter as the spring and refiled with atf/10wt fork oil mix and the difference was day and night. firm ride with much less dive on braking, very stable at high speed (135+) and was very little investment. Just my .02.
