My royal 4000 height adjuster-slips and dose not maintain set height. Any ideas as to repairs?

SOURCE: Rear air ride suspension is not maintaining height

The are ride height adjusters the look like arms. they are mounted on the bottom of the struts and lower control arms that control the height The can be adjust but for the most part if the were working fine before then they need to be replaced. Make sure that there are no leaks in the system.

SOURCE: Clutch is slipping is there an adjustment? 1997 royal star

Yamaha has a curved washer style clutch spring that it uses for this model. These have been prone to slipping from day 1. Normally when you get on the throttle hot and heavy. A new spring will help the situation for a while but you may have to replace the clutch pack to get more pressure through out the clutch pack if the bike has high miles on it. Maybe the dealer would know if the VMAX spring is heavier and would work as a replacement.

Is the height adjuster tight on both sides? if loose the bolt holes may be elongated, both sides set the same? any wheel wobble indicating worn out wheels?.if it checks out as good put the machine an a known hard level surface such as a garage floor and check the clearance by turning the wheels by hand without putting pressure on them, If the wheel still slips the mowing deck may be warped or bent. if all wheels are original there shouldn`t be a question of mismatched wheels ie:different sizes.
