Hi Trev,
I agree with Wolf Zero that it may very well be the so called clutch basket, that bit that holds the clutch together. Stops the steel plates from spinning when clutch is disengaged and provides drive through the steel plates to the friction plates when clutch is engaged.
I can visualize your clutch slipping if the adjustment is incorrect too tight however this would be consistent if the engine was in 1st or 6th
I have had a similar problem with my DRZ250 and this problem is consistant with liots of bikes similar because they operate in the same manner. Mine was draging in 1St …..The bike place I bought it from repaired it under a warranty system.
However when I repair things I go all the way, they just replaced the discs and filed the groves in the clutch basket,
Now I am thinking that your clutch basket is badly worn and the plates are not moving backward and forward as they are required to do.
When you are able to inspect this….couple of things to look out for and checks can only be made when the clutch is disassembled,
· Firstly after disassembly check the basket and if there are wear grooves where the clutch plates sit discard the basket and replace.
· Check that there is no rust on the steel plates this will cause drag.
· If the friction plates have been overheated they may be warped place them on a flat surface of a thick piece of glass and see if they wobble by pressing on the edge of the plates in several places
· If there are blue or brown heat marks on the steel plates check in the same manner to see if they are warped,
· If the friction plate’s show signs that there is some contamination in the linings. Place some emery paper on the glass and rub the plates until they look clean
· Do the same with the metal plates be sure that the plates are kept flat on the emery paper on the glass surface?
· Replace your oil with oil recommended by the bike manufacturer most high grade oils are recommended and unless you are being a cheep skate then buy the cheapest oil such as recycled oil which is sold in supermarkets etc.
Hope this helps but guts feeling it’s your basket always open to discussion and if you find anything diffrent please let us all know
Kind Regards
Champ
