Are the oil injection lines on the GT500 (Part #16820-15033 & 16840-15033) interchangeable with the injection lines on the GT250. I see that the part numbers are different for the two but they look to be very similar in appearance. I have a leak(s) on the injection lines on my GT500 and would like to find a good used set. I have not torn it down to check exactly where the leak(s) are but I do see air bubbles in the far right side line and oil on top of the crankcase when I run her. Too cold here in South Jersey to even think of tinkering in the garage.
Have some other problems I need to address on the bike. Starts fairly easily but will not stay idling off of choke for more then 5 to ten seconds even after being warmed up and ridden. Much harder to re-start after it stalls. Smokes like a banshee but have not noticed any drop in the transmission fluid regarding possible crank seal failure. All in all pretty good shape. I have had it for 2 years and am going to try to get it sorted one way or another for this summer so i can enjoy it. Will try to include pic of the bike. Thanks

Re: GT500 Oil Injection Lines
South Jersey hey? I am a native of Toms River. Spent the first 25 years of my life there.. I sorely miss the ocean and good pizza. There are no oceans in Oklahoma and the pizza sucks 

I was born with nothing and still have most of it left.

Re: GT500 Oil Injection Lines
Coyote, a little further south then you. I am 15 minutes outside of Philly on the Jersey side . But have been to the "Saw Mill" in Sea Side Heights for their world famous pizza a time or three and the Office Lounge in Toms River more then a few times.

Re: GT500 Oil Injection Lines
Oil line compatibility for GT250 and GT500 equals zero. They are not the same.

Re: GT500 Oil Injection Lines
Oil line leaks can be repaired.
There are check valves in the oil line crankcase fittings.
You may be able to clean them & get them to work properly again.
But don't try high pressure air as this will ruin the springs in those valves.
I have a T350 that would develop bubbles in the far right line when it was parked on the side stand for a long time.
But the line would fill back up if you switched to the center stand & left it there.
I think the oil was moving from the highest line (right) to the lowest line (left) when parked on the side stand.
As a general practice, I park my T-series twins on the center stand if its going to be there for a while.
Sorry, I don't have time for a more complete post.
Try searching … there are lots of posts about the oil lines.
