5BE vs. 5JG DVP needle - Has Yamaha fixed this mixup?
Posted March 26, 2001 - 08:49 AM
I finaly yz timed my '98 WR400 and after hours and hours of research on Thumpertalk I ordered new needle and jets. Of course I got the 5JG-14916-DP needle. OOPS. My question is does anyone know if this mixup of the 5JG being a DKP as opposed to a DVP needle still exist or has Yamaha fixed it? I have no clue as to if the needle in my hand is correct or not. AAAGGGHHH! I have the kid at the shop calling Yamaha, but he doesn't have a clue as to what I am talking about. I wish I could call them myself. Good thing it is freezing and snowing here in Michigan or I would be upset.

bike runs good but the plug looks a bit on the lean side. Im going to try clip#4

It is the description that is wrong on the microphiche, not the part number itself.

The microphiche shows.
Part Number (description).
In the description portion for the DKP needle it says (DVP). Under the description of the DVP needle it said (needle). So clearly the needle description is not the item on which they rely.

Take your parts guy back to the service area and make him look in the 2000 YZ426 service manual. It shows 5JG-14916-DP is a (Size) DKP needle. I have a copy in my hand right now, page 7-8. Then show him the needle he gave you is a DKP when you asked for a DVP!!
Tell him you found out on the internet.

the bike runs much better. I tried the clip at #4 and the bike started to foul out but the air temp was cold, still testing.
