So COPS do not cure hot starts?
If they help starts how could they not help hot starts ----i still do not understand.
 
I fixed my hot start issue with the combination of two things. The battery mod, with battery box mod, and bill sewards r/r mod. Hands down a must, at least that's my opinion.

I had a TX500 back around 1975. It would die in traffic on a hot day. Those bikes did run very hot, and the coils would cut out when they got really hot. Giving the bike time to cool off a bit would allow it to start. I replaced the coils, and everything worked fine for the rest of the time I had the bike. I believe a coil can fail due to the combination of age and heat, and replacing either with COPS or a new OEM coil would fix the problem. COPS are less expensive, and IMHO, more reliable. If you have a coil that is breaking down internally, replacing with coil sticks, or a new OEM coil could definitely help performance. And definitely help hot starting, if the engine cranks over properly.. You do need a good battery, charging system and starter motor. COPS won't help a bad battery, or fried stator.
 
I can't take credit for the R/R mod, I heard of it here. I may have been the first to try the SH775 Series Regulator though. In any case, I'm glad it worked for you..

But Bill, the unscrupulous sellers says CURES hot. Look at the snippet below.

Also yesterday we had the hottest city in the US at 100 degrees breaking the old record--I never had one problem starting mine with cops while hot.
 
I've got all the charging and battery mods you can think of done to Godzilla. Series regulator directly connected to battery, high output Venture stator hard wired to Regulator, battery box mod, AGM Gold Wing battery. After the COP upgrade, the bike honestly did start easier cold OR hot. For that reason, the upgrade worked for me. Remember, my coils were over 25 years old, and had over 120,000 miles of use. I never did try replacing the coils with different stock ones. Maybe the same improvement would have happened. I don't know, but in my case the bike did start easier. As I stated, they won't fix a bad starter, stator, regulator, or battery. But if your coils are iffy, they do help.

I don't know about "unscrupulous", but I agree, one could possibly misunderstand that ad.
 
I would still say unscrupulous. Here is the definition.... willing to lie or cheat to succeed:

In the first snippet, the seller mentions that they will increase hp. It was brought up on this very forum (the seller used to be here until he was banned), how COPS did not increase hp. Myself and others could post dyno runs, before and after to prove there was no increase.

Then the seller changed his ebay post, to say that COPS will cure hot starts.

Yamaha fixed the hot start issue by changing to the 4 pole starter in 1990 (thats why upgrading the battery helps so much)

Bottom line, COPS are a good upgrade if your coils are going bad (ohm them out first), cracks dont mean anything in the coils. Maintenance for your electrical system is usually over looked. Check for signs of corrosion, IE around the ends of the wires, around the boots. If the wires have corrosion on the ends, clip of 1/8th of the ends, and good as new. The boots can be taken apart, and cleaned.

One of the things that people always say about COPS...."Well modern sports bikes have them....they must be an upgrade", well actually no. Modern sports bikes are fuel injected, so the coils producing the spark doesnt need to be as powerful. Thats why COPS are not as powerful, as the stock coils. The A/F mixture with fuel injected bikes is more precise, so less spark energy is needed.

Now, like all things there is aftermarket.

I would actually like to try those. 80000 volts. NOW THOSE are an improvement over stock.

Is this the same guy you harassed on Facebook and were told to leave?

Do you have cops or stock coils on your bike?
