    New GP1200R owner...help

    Got a great deal on a 2000 GP1200r. This is my first PWC and It has a few issues to be had. After alot of reading, I stepped the sponsons and got a R&D intake grate. Was all excited to run it....Well something is wrong! Compression is 118/120/119. It is running so rich when you give it gas that it smokes unbelievably and will only rev to about 2500 RPM. My local dealer says there is no adjustment for oil injection and that the pump is shot. I was going to put a block off kit on and a d-plate in. Do you guys think this is the answer or do you have any other ideas? I know nothing about this thing except for what I read here so I am open to any suggestions.

    Cool

    compression is not off by that much,sounds like cable to oil inj. broke (yes it can be adj.)try throwing new plugs in and stick your nose in fuel filler, if smell sour 86 gas . oil pump cable up front is hard to see,you may have to pull pipe(good time for d-plate,clean carb's,check power valves,jet works mod----sorry got carried away

    later cd

    the first thing i did was siphon the gas out of it. Its got brand new gas in it. I put the Waveater couplers on also. I aint looking to mod the machine to much as the whole family will be using it. Just trying to make it a very reliable machine. I downloaded the service manual, and that also says the oil injection is adjustable.

    ya, your dealer is either full of it or doesn't know what he's talking about. I would eliminate the pump anyways with a block off plate and go pre-mix.

    Got a look at the pump and the lines are lined up perfectly. Now I am even more confused. I ordered a block off kit, but now I am wondering if 1 or more of my carbs is dirty.

    Put an oil block off and run premix. Get your carbs rebuilt and rejetted.

    +1, have the carbs gone thru, it's not worth seizing up a motor.

    pulled the carbs off today and what a mess. A bunch of crystalized crap all over the place. looks like they need to be cleaned and rebuilt. any tips on doing this, I have read a ton about it, but never done it before. A local guy wants $120+parts per carb. I am a little scared of carbs since I have no experience.
