I ordered some WR250 clutch springs to fit into my WR450 to give easier clutch pull so that I can learn better control and reduce hand fatigue. I don't weigh much and I am not doing steep hill climbs so from what I have read in the various threads on this subject, putting in light clutch springs should not generally cause an issue with clutch slip.
The question is whether I should go with 3 or 6. I wondered if there was a problem with putting in just 3 lighter springs as surely the 3 original springs would be putting more pressure and therefore increased stress in just three places on the clutch hub? Is this ever a problem? Also would putting in all 6 lighter springs lead to clutch slip in just normal riding conditions?
Finally I have read about the washer mod, putting washers inside the springs to effectively raise the clutch hub towers and create a larger recess for the spring when at full compression. I was planning to do this with my stock springs, but now I am putting in lighter springs would it be a good idea to still do this or will this further reduce the spring pressure and cause problems?
