this is a two part question

one, can you get a tester to fit on the 650, i guess the plug size is smaller than a car plug, and i havnt been able to find any set up to work on the bike

two, if i do find one what is a good leak down precentage

thanks

 

Most good leakdown testers have the right adapters..I used a MAC and it had the right adapter
I have heard 3 percent or less?...for the DS,
You might have to pull the valve cover..to make sure the decompression lever is not engaged(when at TDC)

you can get adapters from mac,matco,snap on ect.mac or matco are cheaper. my rappy ckd at 4%

 

ok thanks, my snap on guy comes around on wendesday and ill see if he has one one truck, i dont like using the mac, or matco due to the salesman who come to our shop, there idiots, i know the tools are good, but these guys propbably dont even know what a compression tester is

 

2% is prefect. 10% needs overhauled. 20% no power.

 

The first leak down test I did..I didn't lock the crank..and I got a false reading..
I went back and re-tested and had 20%...with in seconds it blew a good amount of oil on the floor(out of the breather)
