Are you using oil injection or pre-mixing? There is no additive that I know of. I used to use synthetic when I had a two stroke. I was using oil injection and had less smoke. If you are pre-mixing there isn't much hope as you are burning twice the oil recommended and putting out unecessary pollution at an idle. The only time your ratio is correct is at WOT, the rest of the time it would be a bug fogger.
I have a 1996 waveventure. Oil injection. The reason i was asking this, is because stp makes a smoke treatment. And it advertises that is reduces exhaust smoke. Didn't know if anyone used this or something like it to reduce the smoke. Thanks Joe
I recently perchased a GP 1200 that was modified for premix and I am greatly bothered by the amount of smoke that it puts out. I was told buy the gentelman that I purchased it from that the mod was due to an engine failure because of the injection system. I hear both pro and con opinions for premix and and am on the fence about it. Is the oil injection as problematic as I hear? Can running it that rich be good for the intake? Enviromentaly, I am very tempted to go back to the injection pump. Any real world advice?
Thanks,

I had a GP1200 and it had well over 200 hours with the oil injection system. Never had a problem. And best part of all is that it literally sipped oil. The oil level took a long time to drop. If I had been running premix I would have been using at least twice the oil for nothing. Personally I don't know why people go back to premix, it's like going backwards 20+ years in technology. :dunno:
On your GP if the oil tank, pump and lines are all still there I'd go back to injection. If not it might be too much hassle than for whats its worth. Depends
If you do decide to go back let a pro get the injection system running if you don't know what you're doing because I know you have to prime the pump otherwise you'll have air in the system which can ruin your motor. Plus you need to really check all the lines and what not.
Thank you YamaDoo!
Yes, the infrastructure is all still there. The lines were just blocked off. If I do restore the injection and most likly will, I will install all new lines to assure their integrity. I have a Professional Jetski mechanic in the nieborhood that can do the work.
I was told by the previous owner that the oil failure that caused him to go premix was because of air in the lines. Do you have any suggestions or check procedures that would keep that from happening?
Thanks again for you reply.

the better the oil the less smoke
I was looking into this as well. A local performance oriented shop had a kit that they'd install that replaced hoses and clips used to secure hoses. He said some of the "oil pump" failures are not the pump but the lines.
This is second hand info, discount it as such...
