trike front suspension

Post by tailgunner10 »



I recently purchased a CSC trike that had a trike rake kit installed, steering is easy, but there is no shock absorber action on front fork, really bangs hard on pot holes etc., is this normal after this modification?

The rake kit only alter the rake and not the suspension.
Check fork seals for leaking and oil level. Not sure if you have air assist forks if so check air pressure 6psi.
does your trike sit low on the front as if it leaning forward

How many miles are on the bike? Suspensions do wear out and need replacement.
Do you know if it has OEM springs? Tell a true story: One of the installers I talked to told me, he insisted on installing "stronger" fork springs on the first 6 conversions he sold. After 5 of the 6 asked for their OEM springs be reinstalled, he quit telling customers to replace the OEMs! I replaced my original springs at 25K on the conversion with new OEMs and have been well pleased.
If it seems the front forks have no "action" at all, you need to check the ADV. It's possibly stuck.
Some times after market springs are installed and some of those result in a very harsh ride!
The tire pressure can also be an issue if to high! Someone, somewhere back in time posted 41psi was the proper psi for the front tire on a trike. That's a bunch of nonsense to me! Did that when I first triked. What a bad ride that gave. Reduced to 35psi and all is good.
As for the comment on the front end setting low, if the installer knew what he was doing, fork extensions were added with the rack kit! Might look and see if this was done on yours.

New to Honda, been on a Harley, dont really know much on how a TRIKE should feel. Trike has 23k on speedo.How would I know if it's air assisted? Steers great, but slams hard if front tire hits a pot hole, no shock absorber at all.I put a new Avon trike tire on it right after I bought it, old tire full of cracks and splitting. Service records show rake kit installed, nothing else. No oil leaks anywhere.

Hold the front brake and see if you can push down and get any suspension compression. If you do, bounce it hard and fast. It should "lock up" after three or four compressions. If it won't compress, most likely, as I already posted, the ADV is stuck!
Most bikes will feel harsh if one hits a "pot hole"!
There will be "valve stem" look a likes on top of the fork caps, if someone added schreider valves to the forks.
Your avatar shows you have a GL1800. 1800's don't have air forks from the factory.
