I picked up an older Yamaha Waveraider recently. It's been sitting a bit. I started it on the trailer really quickly to see if it would start. I noticed it smoked a bit. I'd like to run this a bit at the house where I'm a bit more set up to do some work on it and not look like a doofus at the lake and get stranded. I see that I can get a water flush kit on eBay for this but am not sure what to splice or where to splice to install the thing. I'm new to PWCs as this is my first. Also, any ideas about the smoke? I'm thinking it may be as simple as having some fuel additive for winter storage or maybe the rings that would snap back to life with a little heat and fuel running through it. Obviously I'm an optimistic fellow! Anyway, any help would be appreciated!
