Compression Release location

[FrankBDPS]

I am having some trouble starting the bike. Once it starts, it runs great. I figured compression release would help with the starting.

What kind of starting issues are you having? What motor do you have? 107,117 or something else. You may install compression releases and still have starting issues. They are not a cure all. Good luck.

107 engine. It just seems like it is having a hard time turning over, Slow. I'm going to start with plugs to see if that helps. It has been sitting for 2 years. I may need a stronger starter. Idk yet. Compression releases just seemed to make sense and was trying to see how hard it would be to add.

put in a higher Kw starter, next you need a more CCA battery, then you need larger diameter cables.... that road never ends . Test your current battery, check its about 310 CCA, be happy. compression releases do help, but engine doesn’t need to crank like a sewing machine. I have a 1.7kw high torgue starter on -03, turns the engine over somewhat relaxed speed but starts the engine just great.

Mine does that when its cold or the battery is tanking. Last time I pulled the starter thinking it was the problem. NOPE. New battery solved it.

Agree Check your battery first if you want to replace it with a larger starter I recommend ultima thunder fire starter they are reasonably priced and they have some beefy starters. I have used them in both bikes and really like them over more expensive starters that didn’t last

Its supposed to be 500cca. Ill check thr battery

 

[FrankBDPS]

If that battery has been sitting uncharged for two years it is more than likely trashed. Good batteries,cables,clean connections and good starters are key to starting these engines. Once you get it turning over good then worry about the tune up.

I agree also with checking battery and connections. Compression release only effects the first compression stroke. If the engine gets past that but cranks slow, release is not your problem. Since your bike runs great after it starts have the battery tested and if its good maybe the starter is getting tired. A new battery always feels good!

Battery is new so maybe the starter then

"new" batteries are not always good. I had (2) new interstate batteries in a row leave me stranded on the side of the road within a week. never again. went with Braille.
both 320 cca interstate batteries were actually 270 cca rebadged yuasa.

I do not believe on 500 CCA unless it’s lithium. there are no rules , just marketing. That makes me think would I rather believe company that tells honest 310 or claims the battery is 500.... If you examine how to increase CCA, you’ll find the only way to do it is to increase the surface area of the lead panels, make more thinner, make them curvy ... result is thin plates very close to each other... sure way to make a battery that doesn’t last if the bike vibrates or battery gets hot....

Anyway do the cables get warm when you start? good battery, bad cranking may well be loose cable. easy to check and doesn’t cost anything. If the cable on battery end is loose the battery connectors tend to all the sudden.

Correct battery CCA for 2007 K-9

Does anyone know what the correct CCA for a 2007 K-9 is

There is a few models including the K9 that you don’t have to take the rocker boxes or tops off to change the releases. The backbone is high enough to get the tool in both heads. You just splice the wires into the original coated wires and your all set.

I haven't seen that. Usually there's MAJOR misalignment in the rocker boxes to prevent compression release removal.

This all helps me a lot. I haave a 2000 Wolf that is very hard to turn over. The new battery was not the answer so I will pull it to check the CCA, it isn't visible on any label on top. Was thinking Interstate till I read it was just a relabeled too small battery. I can't see any sign of any part of releases sticking through the valve covers, so I guess it didn't come with them. I have a very pricey paper/notebook type service manual for my bike coming soon and maybe it will guide me right.

Well what you cant find in the book we will all do our best to help you...someone on here will know

Thanks.

Is there a rubber in the hole in the top of the head? Push on that and u should feel like you’re pushing a button

Wow John, I think of you as an engine god, and bow down to everything you say about engines. But yes, on the K9's and choppers, you can change the CR's without removing the rockers. I've changed many of them. And once, out of pure laziness, and the fact we had the primary off, I unbolted the engine on a Mastiff, and slid it over to change them out.

 

[john sachs]

The key word in my post is: "USUALLY". I don't get a whole lot of drive in bikes, as I do parts to modify. I've been able on a couple to remove the releases without removing the rocker arm saddle. This holds true on Harley Davidson factory bikes, that the owner has replaced the stock engine with an S&S engine. I've had S&S pay for the removal (under warranty) knowing the rocker boxes do have misalignment.
