timing problem?

6 posts in this topic

On Saturday, I changed out my timing chain in my 2000 YZ 426. It was pretty streched out.

Anyway, I put everything back together and it fired up with one kick.

Went out riding yesterday and I noticed that I'm lacking a little horsepower compared to the way it ran before I changed out my timing chain. It's not a huge horsepower loss but there is a difference. Anybody have any clue as to what is wrong? Maybe i didn't align the cams correctly?

yes, I made sure i was at TDC. I followed the manual pretty closely. What does 12 pins mean? Thanks!!

12 pins in the timing chain between the punch marks on the cam sprockets.

I think the WR's are 13, i times my WR to YZ specs which was 12 pins between!

So, that is 12 pins, not 12 links. It seems there are a lot more than 12 pins between those punch marks than just 12. There are 2 pins per link.
