I've posted on here before with a few of my troubles but I thought I'd make a list of them and see if anyone can tell me what my underlying issue is.
- Burning oil - about 100-150ml every 60-80kms
- Backfiring on decel a lot - I put a new exhaust on after these problems started but it never backfired as much as now.
- Very hard to start when hot, a bit hard when cold.
- Won't idle - The idles as far as it goes. strange thing is it seems to drop randomly and stall and then sometimes it sounds too high.
- Sometimes the kick starter seems to 'skip' teeth.
Things that might give clues:
- All started shortly after the bike was drowned (it had water coming out the exhaust when I tried to start it.) Not sure if that's just a coincidence or not.
- The mechanic said the timing was slightly off (the cam markers didn't line up exactly)
Things I have done:
- Had the valves adjusted - no difference. One of front valves (I think exhaust?) was tight so it was loosened up.
I just spent around $300 having the valves done and a service which made no difference at all so I'm a bit hesitant to take it to the dealers to spend more money for nothing, even if they do have the correct tools that may help them find the problem.
It is still ridable but very frustrating so I'm not getting out and enjoying it much any more. It seems to run smoothly when it's moving and the power loss I feel may just be in my head. Went out on an organised ride last weekend and it turned out to be mostly tight single track so it was difficult to keep the thing from stalling.
I guess what I want is some good idea's where I can narrow down the cause. I fear that if I go to the dealer with my crack pot thoughts they'll end up doing something drastic and unwarranted that doesn't fix the problem. To me the oil burning seems to point to a pretty major issue and doesn't seem like it could be related to the starting problems, but that's just my crazy theories. Is it normal for these things to burn oil at all? I had a 2008 WR450 that never burnt a drop.
Thanks in advance.
