Title: Oil Pump Injection Nozzles
Post by: Diablo007 on September 17, 2020, 01:04:46 AM
The oil injection nozzles I have fit loosely in the carburetors.  One side is OK, but still looser than I would like.  The other side is loose.  What is the best way to seal them?  RTV silicone?  Yamabond 4?  Any tips would be appreciated.

Judging from what I put in my amazon cart so I would remember, Chuck says Loctite 640 High Strength Sleeve Retainer.  Hopefully someone better at searching the site can confirm.  Posted this year, I bet.

Yamaha recommended contact cement.
The locktite  will work if you have it, or use JB weld

:thumbs: It's a little Yamaha heavy but it's intended to be our go-to resource for specs and other info tidbits.

Thanks!  I guess my search skills need some honing also.  I thought I had checked the Tech Library but apparently not good enough.  Now that I see the link to the green loctite solution I realized I had read that before this bike was back-burnered.  Fired it up today and it was awesome.  First engine I have totally rebuilt.  Well, I left the oil pump alone as I have been told many a time that they are bullet-proof.  (Here come the comments....)
