That is one way of fixing it.He got scared of this issue, didn't have an extended warranty and converted to carbs and ported 700 cylinders.
Ha ha.. what if it is a failed injector or a plugged injector... what/who fixes that. You are out of warranty, you fail a piston, you do a pressure decay check on the engine before tearing it down. You got lucky and the cylinder was still ok, you put a new piston in, you put a new filter on the inlet of the fuel pump, you do a pressure and flow test on the electrical pump and you put it back together. Now doo under warranty probably would put a new injector on... but me or you.. we look atThat is one way of fixing it.
The other would just be to change the fuel filter, do a compression check and call it a day, maybe toke the y-pipe and inkates of to check for scratches in the pistons.
Just curious, how many miles on your sled?thanks for all the info. I'm going to have them check the injector to see if they can find anything there. I don't believe it was bad gas. If pistons are going to melt down due to gas, then brp needs to figure out what is the cause and fix it. I've been loyal with doo since I started riding and this is my first real disapointment. Especially with an etec.
Was there no grease leakage?My advise is this, Have them perform a leak down test. It is very simple to do and they shouldn't charge that much. It will reveal any and all air leaks. The y-pipes are good for cracks. On my sled(500ss TnT) I was told bad gas and rebuilt thinking that, then 36 miles later I had to do a second rebuild which I then did a leak-down test which revealed the PTO seal was bad. My sled had 4000 miles on it. The sled is at 5300 miles and running strong. You fail to mention which piston. Take a little extra time now and you will be rewarded later.
What mileage?Have a 2009 gade 600 etec, went down last ride of season. Finally got to dealer to take a look and said I had a siezed piston, probably due to bad gas. Anyone heard of this? and any thoughts?
Change your fuel filters.Original fuel filters on our two 09' etecs.. 7,000mi. each.. compression 140 or better in all cylinders. No issues to date. We just keep riding them and they just keep running great. Knock on wood
