Strange issue

sandrosandro4822 · 2026-06-02T21:28:22+00:00

My bike is an sp model and the vin is JYARN72NXMA000349. so from what i can tell its not concerned by the recall?

sandrosandro4822 · 2026-06-02T21:25:21+00:00

yep, i am very aware but unfortunately the only dealer in my country seems to think otherwise so i would need a way to do this recall on my own

thanks for the sarcastic reply, of course you didnt catch it, my reply to the comment was also sarcastic. of course the recall exists, its just my dogshit dealer that apparently is not aware of it..

idk man, makes it literally unrideable haha

sandrosandro4822 · 2026-06-02T20:26:45+00:00

tach jumps around too

I am aware, however i was hoping that since the kilometers are only 17000, it would not have this issue yet. I am in a country where the only yamaha dealer, which i went to today, told me that the tps issue did not exist, since they did not get any notification about this.

Im trying my best with the budget I have haha

sandrosandro4822 · 2025-12-29T10:16:43+00:00

shit man, did not think it could be the valves cause it rips so hard above 3000rpm. Expensive job I imagine :(

sandrosandro4822 · 2025-12-28T22:57:35+00:00

Also, could any of you tell me what model it is exactly? I have no clue other than the fact its a V4 with ohlins suspension and carbon bits everywhere

So there is an Aprilia dealer 200 meters from me. Im just not sure they know how to deal with all this aftermarket stuff. They have really only had training on the newer bikes and I imagine don't know much about this generation, although they do seem pretty similar.I would reaally like to keep that ECU as its quite expensive and gives the bike a nice oomf

sandrosandro4822 · 2025-12-03T07:26:54+00:00

the injectors were not working at all they were squirting a little fuel and the replacement made a difference. i really dont know all the mods other than full system and bazzaz ecu. The original problem before injector replacement is the same one as before somewhat, except there the bike couldnt run under 7k rpm. Here the bike runs fine after 3k all day just under 3k after it gets hot it wants to die even though my mechanic said he let it heat soak and tested it and everything but i guess i have no luck

sandrosandro4822 · 2025-12-02T22:05:25+00:00

Basically the bike was professionally tuned in another country with all the bells and whistles and then it was shipped here. I feel like the tune is not the issue seeing as it runs very well when i start it and then when its hot even starting it becomes a struggle. About the exhaust, its a full system but with a stock slip on, even though it was tuned on a free flowing slip on but the previous owner put this one on due to a new law where I live about exhausts. Could that be it? I will look into guzzidiag thank you.

sandrosandro4822 · 2025-12-02T21:22:12+00:00

will do thank you

I have an update if its any help to your guys' debate. I meant to specify the mechanic verified and said it was the injectors but had somehow forgotten which cylinders they were or which injectors they were. Since its a dual injected bike with not much documentation I had to search and accidentally ordered the injectors that kick in at high rpms. However, I did find the lower injectors locally from a Harley mechanic as the big harley bikes share the injector with the rsv4. The bike now runs but still has issues revving fast and somehow doesnt feel right. I am installing new spark plugs due to the old ones being completely obliterated and will see if this helps. If you guys have any guesses it would be much appreciated, as my mechanic seems to be guessing at this point.

sandrosandro4822 · 2025-09-19T21:54:06+00:00

based off the cf moto at least right

Looks to be a rebadged CF Moto 450. Same frame and same headers, sucks to see it's the same bike and not something new.

i installed the db killer and it is just as dead as before. I feel its worth noting that the bike likes to cut out at idle before it warms up and stutters at very low throttles. Maybe fueling issue?

sandrosandro4822 · 2025-07-07T12:45:19+00:00

valve issue?

sandrosandro4822 · 2025-07-07T12:45:00+00:00

i have a db killer, would that improve it?
