Is there any negatives for filling the cross over passages? I have a stock ski except carbs jetted to OSB recipes and flame arrestors. Do you lose any low end power from filling the passages?

I am parting out a GP1200R. The engine had a broken powervalve shaft which caused a piston ring to scrape against the power valve. No major damage took place. I caught the broken shaft while cleaning...

I have a set of Flame Arrestors for a 66V. They were used for half of a season on a GP1200R. The water socks (which I never used) and the hardware for mounting are...

Another option would be running Tee on your oil lines for the primer. Keep the Tees close to the carbs. Add check valves to keep the oil and premixed gas flowing the right direction. That will allow...

I am in Florida and thinking about a new watercraft. I have read reviews on here on SeaDoo and Yamahas but where can one really test drive a watercraft before purchasing? I have looked at rental...

Do you have a picture of the break? I am curious how bad it is and if JB Weld is a good option. I have never had good luck with JB weld on anything.

They make T-Handle adjustment screws for the High and Low adjustments. Since you are already pulling the brass caps out, you might want to replace with the adjustment screws.

The high and low adjustment screws are behind bass caps which maybe painted over making them tricky to spot. See the attached thread on how to remove them. How does the Waverunner run with the carbs...

I have a GP1200R and I have only run 87 octane with 10% ethanol. I have had the ski since 2001 and yes I rebuild and clean the carbs out once a year. I do not run Non-ethanol fuel because it is out...

I would be interested in this type of trip once COVID is over. I am in the St. Petersburg area but will take the trip down for a weekend trip.

Why would you trim the wings? Is it a fitment issue on a GP1300R or some type of performance gain?

I know this is an old thread but I will be moving to Colorado from Florida later this year. I am debating on bringing the GP1200R with me or trying to sell it in Florida. Anybody still there riding...

I have a blown engine in my GP1200R. What are the advantages of a Sea Doo engine versus a Yamaha? I have always had better experiences with Yamaha watercraft than Sea Doos.

Does anyone have pictures of the routing of their return lines with the tee? I thought I had my Tee low enough to pick up fuel but I was wrong. I am going to drop the return line almost straight down...

Go to Riva Racing's website. They have performance kits. There stage 1 kit is about $2,000 and will get you into the low 80s. MaptunerX will be the first mod I would make to your ski.

Anyone on here live or ride around the St. Petersburg Area. I have a 2001 GP1200R. My usual route is launching at Maximo Park and doing a loop around Fort Desoto.

Rebuilding the carbs will be a great hands on project. You'll learn alot. There are many people on here to help out in the process of the rebuild. There are alot of carb rebuilding posts on Greenhulk...

How many hours are on the engine? Is it the original engine? With low compression, it maybe after to completely rebuild the engine if your already going to do a top end job.

Cleaning the...

Not sure exactly what your question is but it looks like a fun project. How many hours are on the engine or is it new? I wish you lived closer to St. Pete because I wouldnt mind helping you out with...

I always premix at the pump. I add 5 gallons of fuel, then the appropriate amount of oil, add 5 more gallons, and then oil, and then top off with a few more gallons and whatever oil per the remaining...

Have you tried a compression test on the cylinders? 2 strokes are pretty simple. Fuel, spark, and some compression. You should be able to pick up a compressor for cheap at any auto store.
