\u3007 Idle speed sensor (green) – Control of RPM<\/p>\n\n\n\n
\u3007 Sensor map (purple) – Engine control<\/p>\n\n\n\n
I assumed that one or more of these were broken, so I bought these parts in Brazil.<\/p>\n\n\n\n\n\t\t\t\n\t\t\t\tI have all the parts so I’ll see if I can replace it myself.<\/p>\n\n\n\n\n\t\t\t\n\t\t\t\tThis is the idle speed sensor.<\/p>\n\n\n\n
Well, I think I could remove it myself, but if I make a mistake, I won’t be able to bring it back to Paraguay, so I decided to look for a repair shop.<\/p>\n\n\n\n
The motorcycle has over 50,000km on it, so I thought I’d have the inside of the engine checked as well.<\/p>\n\n\n\n
<\/p>\n\n\n\n
To the repair shop<\/strong><\/h4>\n\n\n\nWell, I’m currently in Uruguaiana<\/p>\n\n\n\n
After this, I plan to go to Ituzaingo in Argentina, passing through San Borja, so I contacted several repair shops in both Uruguaiana and San Borja<\/p>\n\n\n\n
I sent more than 10 messages on WhatsApp, but only 3 replied<\/p>\n\n\n\n
I took it to the repair shop that I had contacted several times and seemed the most reliable<\/p>\n\n\n\n
*It was close to where I was<\/p>\n\n\n\n
I had contacted him in advance, so the mechanic knew the situation<\/p>\n\n\n\n
I told him that I already had the parts and asked the price including the engine check, and he told me R$700, about 126 USD<\/p>\n\n\n\n
Well, including the engine check, it would be about that price in Japan, so I agreed<\/p>\n\n\n\n
I left my motorcycle and went home<\/p>\n\n\n\n
Message from the mechanic<\/strong><\/h4>\n\n\n\nThe next day, I received a message from the mechanic.<\/p>\n\n\n\n
He said to me, “There’s something I want you to look at, so can you come over?”<\/p>\n\n\n\n
When I went to the repair shop, he told me, “There’s a crack in the cylinder head.”<\/p>\n\n\n\n
When I checked, it was a small area and hard to see, but I definitely found that the spark plug socket was cracked.<\/p>\n\n\n\n
I had to choose between replacing it or leaving it as it was.<\/p>\n\n\n\n
I still had about 80,000 km to drive, so I chose to replace it without hesitation.<\/p>\n\n\n\n
I told him that I was going to buy a new cylinder head and went home.<\/p>\n\n\n\n\n\t\t\t\n\t\t\t\tThis is after I removed the cylinder head, and this is the photo where I can actually see the crack.<\/p>\n\n\n\n
It has lines on either side of the center spark plug.<\/p>\n\n\n\n
<\/p>\n\n\n\n
I buy parts<\/strong><\/h4>\n\n\n\nI immediately checked the usual website.<\/p>\n\n\n\n\n\t\t\t\n\t\t\t\tI see, it looks like I need to change all of these.<\/p>\n\n\n\n
I searched for the product by model number.<\/p>\n\n\n\n\n\t\t\t\n\t\t\t\tOK, I understand.<\/p>\n\n\n\n
This is a genuine HONDA product, and I did not get the model number wrong.<\/p>\n\n\n\n
So I bought this.<\/p>\n\n\n\n
The price was R$1,420, about 253 USD.<\/p>\n\n\n\n
<\/p>\n\n\n\n
Rio Grande do Sul is at the southern tip of Brazil, so it will take about a week for the product to arrive to me.<\/p>\n\n\n\n
I will wait.<\/p>\n\n\n\n
It arrived but\u2026<\/strong><\/h4>\n\n\n\nWell, the product arrived, and it was the same product with the crack.<\/p>\n\n\n\n
“Well, that’s because you ordered it,” you thought.<\/p>\n\n\n\n
Actually, before I received it, I was looking into the problem with the cylinder head.<\/p>\n\n\n\n
Then I found that there were many reports of this problem with the XRE300, and HONDA was also aware of it.<\/p>\n\n\n\n
I found a statement that the cylinder head had been resolved from the 2016 model.<\/p>\n\n\n\n
I thought this was the model in which the problem had been resolved, but it seems that was not the case.<\/p>\n\n\n\n
<\/p>\n\n\n\n
Just to be sure, I took it to a repair shop and checked with the mechanic, and he said, “It’s fine to replace it with this,” but with this product, the crack will appear again, so I will have to replace it again.<\/p>\n\n\n\n
So, feeling sorry, I went through the return procedure at Mercado Libre.<\/p>\n\n\n\n
At that time, the mechanic told me, “You need a tablet, so please buy it,” and told me that there was an additional part to purchase.<\/p>\n\n\n\n
First, I look for a solution<\/strong><\/h4>\n\n\n\nWell, first I need to find a cylinder head that has the problem solved.<\/p>\n\n\n\n
I tried searching for the model number of the 2017 model on the same HONDA parts search screen, which is after the 2016 model that had the problem solved.<\/p>\n\n\n\n\n\t\t\t\n\t\t\t\tThe model number has certainly changed.<\/p>\n\n\n\n
In the 2013 model, it was 12010-KVK-B20, but in the 2017 model, it is 12010-KWT-D20.<\/p>\n\n\n\n
The big difference is that the spark plugs have been made thinner and longer to prevent cracks, so I will also look up the spark plug model number.<\/p>\n\n\n\n
In the 2013 model, it is 31907-KVK-B21.<\/p>\n\n\n\n
In the 2017 model, it is 31907-KWT-D21.<\/p>\n\n\n\n
I will search for the product on the Internet.<\/p>\n\n\n\n
First, I searched for the 2013 model, 31907-KVK-B21.<\/p>\n\n\n\n\n\t\t\t\n\t\t\t\t<\/p>\n\n\n\n
And this is the 2017 model<\/p>\n\n\n\n\n\t\t\t\n\t\t\t\tThese are obviously different in thickness and length.<\/p>\n\n\n\n
That means I was able to confirm that I was not wrong with this cylinder head.<\/p>\n\n\n\n
<\/p>\n\n\n\n
Fits or not<\/strong><\/h4>\n\n\n\nI was only able to find a little information on the Internet, but I often see sales sites such as Mercado Libre saying that it is compatible with models from 2010 onwards.<\/p>\n\n\n\n
However, I should not trust everything that Latin American sellers say.<\/p>\n\n\n\n
So I decided to compare all the model numbers of the products around the injection between the 2013 model and the 2017 model.<\/p>\n\n\n\n\n\t\t\t\n\t\t\t\t\n\t\t\t\n\t\t\t\tThe model numbers of the cylinder compressors that connect to the cylinder heads are the same for both the 2013 and 2017 models.<\/p>\n\n\n\n
That means they are compatible.<\/p>\n\n\n\n
<\/p>\n\n\n\n
However, there is one thing that bothers me.<\/p>\n\n\n\n\n\t\t\t\n\t\t\t\t<\/p>\n\n\n\n
The model number of the second camshaft is different.<\/p>\n\n\n\n
I tried looking for this too.<\/p>\n\n\n\n\n\t\t\t\n\t\t\t\tIt’s R$430, about 76.6 USD, but it’s out of stock<\/p>\n\n\n\n
If I were to exchange it, it would be better to have two, so I checked again<\/p>\n\n\n\nThe price is R$603, about 106.6 USD<\/p>\n\n\n\n
This is a bit expensive<\/p>\n\n\n\n
<\/p>\n\n\n\n
By the way, the price of a 2017 cylinder head is R$2,150, about 392 USD<\/p>\n\n\n\n
If possible, I would like to reuse the current camshaft<\/p>\n\n\n\n
The result of my worries<\/strong><\/h4>\n\n\n\nThere is little information about it, so I watched a lot of Brazilian YouTubes that explain the problem.<\/p>\n\n\n\n
But they talked about replacing the cylinder head, but no one talked about the camshaft.<\/p>\n\n\n\n
So I thought it would fit, and I passed on buying the camshaft.<\/p>\n\n\n\n
I bought a set of cylinder heads anyway.<\/p>\n\n\n\n\n\t\t\t\n\t\t\t\tThe packaging was careful<\/p>\n\n\n\n\n\t\t\t\n\t\t\t\tIt’s a genuine HONDA product, but the burrs are noticeable.<\/p>\n\n\n\n
I later asked the mechanic, “Is this a fake?”<\/p>\n\n\n\n
He then told me, “Look, look here. It says Made in Brazil here, right? This is what it is.”<\/p>\n\n\n\n
I was convinced when he told me that.<\/p>\n\n\n\n
<\/p>\n\n\n\n
I compared the spare spark plugs I had with the spark plugs that came with it.<\/p>\n\n\n\n\n\t\t\t\n\t\t\t\tThis is correct from the information I compared previously.<\/p>\n\n\n\n
Now that I have finished checking, I will have the mechanic install this cylinder head.<\/p>\n\n\n\n
<\/p>\n\n\n\n
About tablets<\/strong><\/h4>\n\n\n\nWell, when I took the returned cylinder head to the repair shop, this is the tablet the mechanic told me to buy.<\/p>\n\n\n\n\n\t\t\t\n\t\t\t\tApparently this is called a “valve pad”.<\/p>\n\n\n\n
This was the first time I’d heard of it, so I looked it up.<\/p>\n\n\n\n
It says there that it “adjusts the clearance between the valve and the camshaft<\/strong>“.<\/p>\n\n\n\nThat part is number 12.<\/p>\n\n\n\n
It says that in order for the engine to produce optimal power when the pistons move, the appropriate gap between the camshaft is necessary.<\/p>\n\n\n\n
The number written on the tablet is the thickness.<\/p>\n\n\n\n
There are many types.<\/p>\n\n\n\n
However, I won’t know the thickness of the tablet I need until I assemble it.<\/p>\n\n\n\n
When I checked with the mechanic, he told me to order four 200s, so just to be safe, I ordered not only four 200s, but also 190, 198, and 208.<\/p>\n\n\n\n\n\t\t\t\n\t\t\t\tI’m going to the repair shop with these.<\/p>\n\n\n\n
<\/p>\n\n\n\n
To the repair shop<\/strong><\/h4>\n\n\n\nWell, I went to the repair shop with the cylinder head<\/p>\n\n\n\n
The mechanic told me “This is fine”<\/p>\n\n\n\n
I waited for 3 days, but he didn’t contact me, so I went there to check directly, and he told me “tomorrow”<\/p>\n\n\n\n
In Latin America “tomorrow” doesn’t mean “I can do it tomorrow”, but “I won’t know until tomorrow”, so we need to be careful<\/strong><\/p>\n\n\n\nI checked with him the next morning<\/p>\n\n\n\n
He told me “afternoon”<\/p>\n\n\n\n
Then he told me at noon that day<\/p>\n\n\n\n
“You bring the tablet number 208 at 14:30”<\/p>\n\n\n\n
I’m glad I bought it separately<\/p>\n\n\n\n
In Uruguayana, there is a siesta, so the afternoon starts at 14:30<\/p>\n\n\n\n
I was thinking “Are you really going to finish today?”, but he contacted me and said he finished at 17:00<\/p>\n\n\n\n
I will check it<\/strong><\/h4>\n\n\n\nFirst I would check to see if the FI light issue is resolved.<\/p>\n\n\n\n<\/video><\/figure>\n\n\n\n<\/p>\n\n\n\n
That was resolved.<\/p>\n\n\n\n
And the idling was stable at a low value.<\/p>\n\n\n\n
<\/p>\n\n\n\n
I couldn’t be sure until I drove it for a bit, so I told him I’d come back right away if there was a problem and paid.<\/p>\n\n\n\n
That’s not what you said<\/strong><\/h4>\n\n\n\nThe amount I was initially told by him was R$700, about 126 USD, but the amount he charged me was R$1,270, about 226.6 USD<\/p>\n\n\n\n
When I asked for a breakdown, he told me, “The cost of replacing the cylinder head is not included in the initial amount. The cost of the replacement is R$500. The remaining R$70 is for the oil change.”<\/p>\n\n\n\n
I also ordered the “inside cylinder check” at the beginning, so I thought the replacement was included in the price<\/p>\n\n\n\n
And I did not hear from him that there was an additional charge if I replaced it<\/p>\n\n\n\n
If I replaced the cylinder head, I would also need to change the oil, so I certainly ordered it<\/p>\n\n\n\n
R$700 is quite expensive just to replace the parts around the injection and the chain<\/p>\n\n\n\n
I was disappointed<\/p>\n\n\n\n
This is a Latin country, so I should have checked all the prices every time I added something new<\/strong><\/p>\n\n\n\nThis was my mistake.<\/p>\n\n\n\n
Check the run<\/strong><\/h4>\n\n\n\nThe next day, I was planning to drive a long distance in one day, so I first tried driving about 10km around the neighborhood.<\/p>\n\n\n\n
Because the engine idle is low, I use the clutch a little differently than before.<\/p>\n\n\n\n
Perhaps because the engine has not yet been accustomed, I felt that the engine was a little hard at low revolutions.<\/p>\n\n\n\n
However, compared to before, it has improved after 4000 rpm.<\/p>\n\n\n\n
The only concern I had, whether the camshaft would fit, does not seem to be affected at the moment.<\/p>\n\n\n\n
However, because the RPMs were lower, the engine started stalling every time I stopped at a traffic light.<\/p>\n\n\n\n
I’ll wait and see.<\/p>\n\n\n\n
Check the vehicle<\/strong><\/h4>\n\n\n\n\n\t\t\t\n\t\t\t\t\n\t\t\t\n\t\t\t\tOnly the cylinder head part is obviously a different color, which I find strange, but I will try washing the car when I get back to Asuncion<\/p>\n\n\n\n
I also need to get the tar off the bottom<\/p>\n\n\n\n
<\/p>\n\n\n\n
I will also look around the sprocket<\/p>\n\n\n\n
It was in a bad state before<\/p>\n\n\n\n\n\t\t\t\n\t\t\t\tThe chain is well lubricated, so that’s good.<\/p>\n\n\n\n
Now I can ride with peace of mind.<\/p>\n\n\n\n
Check for other possible problems<\/strong><\/h4>\n\n\n\nJust to be on the safe side, I looked into possible problems that may occur in the future.<\/p>\n\n\n\n
Broken main fuse<\/strong><\/p>\n\n\n\nThis problem occurred soon after I bought the motorcycle, so I bought a spare fuse.<\/p>\n\n\n\n
Overheating and cracking of the cylinder head<\/strong><\/p>\n\n\n\nThis will not occur in the future because I replaced it with an improved product.<\/p>\n\n\n\n
Defective nozzle and pump<\/strong><\/p>\n\n\n\nThis has also been solved by me this time.<\/p>\n\n\n\n
I have a DENSO fuel pump, so I will buy a spare injector.<\/p>\n\n\n\n
Defective kickstand frame<\/strong><\/p>\n\n\n\nThis is a structural problem. It seems that the kickstand can break from the base.<\/p>\n\n\n\n
This has caused me trouble.<\/p>\n\n\n\n
This motorcycle has a center stand, but when I’m carrying luggage, I need a side stand.<\/p>\n\n\n\n
There are welding shops in every town, so I will keep an eye on this and see how it goes.<\/p>\n\n\n\n
<\/p>\n\n\n\n
These are the main problems.<\/p>\n\n\n\n
I will go back to Asuncion and upgrade this for now.<\/p>\n","protected":false},"excerpt":{"rendered":"
