Spark plug change

Bike has 22K on it and I figure its time for new plugs, also considering checking the valves at the same time but figuring out if I can confident enough for that.

I have the vacuum pump and have refilled the rad before, also have spark plug puller from my 12GS, new spark plugs and new antifreeze but have a couple of questions.

Once the rad is drained, any tips for removing the rad or is it straight forward?
What is the spark plug gap?

If I do the valve check while I am there what parts are needed?

Re: Spark plug change

The valve check took me a while to learn..... (Spare engine to play with)

It will require to remove the radiator completely.
Leave the pump on the engine. And dont touch!

Clean the area. Plenty of sand and small crap lives there
Drain Engine Oil.
Remove SLS Plastic lines....
Remove stick ignition coils + spark plugs

Remove clutch cover
You need to turn the crankshaft

Unscrew the Valve cover.
Get a good set of metric feeler gauges. 2-3

If you are already struggling at removing the radiator,
DONT attempt to check the valves.

Use the manual.

Re: Spark plug change

Andy, look into soaking the rad to get all the crud off. I only run 3 temp bars now.

Re: Spark plug change

Only need to remove the little (2") plug over the crank on the right side not the whole cover to turn the engine. When you remove the radiator take pictures of all the little stuff and where it is. Do not gap the plugs, if they are out of spec use new ones. It is hard but do able to measure the intake gaps. Your bike more than likely will be in spec at 22K miles. You need to remove the valve cover gasket, clean the old corner sealant off and use some new high temp O2 sensor okay stuff in each inside corner of the gasket, only a tiny bit. Use a torque wrench as needed. Use a coil puller not pliers to pull the spark coils. Carefully pry the black plastic secondary air tube on top of the rocker cover. Work it loose. Have some oring grease to lube the orings going back together. Manualy clean your radiator with a tiny pick first, then air, then brake cleaner solvent then hot soap and water rince. I also have a soft wire brush to do the radiator to get the bugs loose first.

Yea, those guys can get into those small spaces and really do a good job. They have really bad personalities but will work for a reasonable price.

Sorry Beech, I couldn't resist.
