Hey Thumper Talk community I've been all over the forums trying to find out what is going on with my 09 drz400sm clutch. So during the end last riding season I noticed my clutch lever started feeling poor. Just didn't give a very good feel but still functioned just fine. I thought the lever just needed to be adjusted. So in preparing for this up coming riding season here in Minnesota I started to adjust my clutch lever. No matter how I adjusted it at the lever/perch/cable area I could not get it dialed in. I then proceed to work on the clutch arm and see if that was the problem. From what I was reading the clutch throwout post needs to be rotated all the way counterclockwise, then the arm place in either the original position or parallel to the bike. I feel like I have tried every position and every time it leads little to no room in the cable to adjust it at the perch and wont fully disengage the transmission. The clutch lever has great feel but no slack in the line and will barely allow me to rotate the rear tire while the lever is in and in gear.(not fully disengaging) I started to think something inside the clutch was wrong even though it worked fine last season. I followed this clutch inspection guide and everything is in tolerance. I'm kind of stumped. I even tried to put everything back to how it was last season to see if i could get something but no luck. I have zeta levers and a replacement cable (original cable snapped). Both worked fine in the past. Let me know if you have any suggestions. I appreciate your time. -Justin
Alright TT Gentlemen.. I appreciate any and all who have commented on my posts, without TT and the knowledgeable people in it, things would have taken me much longer. Anyway, I was shimming my valves the other day,before I did it when I checked the clearance.. There was none. I couldnt fit my smallest feeler gauge between any of the valves and the bucket. both on intake and both on exhaust would not fit. I checked my compression before I did this, and it was only at 60/70 PSI which I know is far too low. Before I tear into the engine, I want to get everything I need.. so if A new piston is in store then so be it.. But would valves that have far too little clearance at TDC cause low compression when cranked? Thanks again guys! - Brad
