Tips From The Toolbox
There are several reasons why your clutch may slip or drag.
1) Your clutch may drag if you do not have enough free play at the handle bar hand lever or at the scroll. You should have 3-5mm free play at the tip of the scroll arm and 3mm at the hand lever.
Note: the operating pin bearing may seize if there is insufficient clearance.
2) Your Stormer clutch may slip and drag if you have the early type pressure plate fitted. Ensure you have the later, post '72, design pressure plate #0710132 (can be purchased from our on-line store)
3) You may have the incorrect quantity and grade of oil. See fuel & oil tip.
4) Your clutch may slip if the friction plates are worn excessively. Stormer friction plates should measure 0.090" thick. The wear limit is 0.002" We have new replacement plates with fibre friction material available #40906
5) Your clutch may slip if the diaphragm spring is weak. Replacing the diaphragm spring can also be a cure for worn friction plates.
We offer an up rated spring kit (#USK) which is 25% stronger than the original spring and has a self centering effect due to a re-designed bearing adaptor. If your casings are out of alignment your clutch may "drag". Our up rated spring Kit will help solve this problem too. USK Up rated Spring Kit, fits Starmaker and Stormer.
Starmaker clutch plates are not interchangeable with Stormer plates.
It is possible replace your complete Starmaker clutch for the later Stormer clutch. Please contact us for a price.
