Hi guys, and girls i have problem with my speedo on my Yamaha TZR50 '03, speedo is showing just 00KMH, it is electric one, digital, do someone know what i swrong or what it might be? Thanks for helping..

Thank you man, i cleaned it and now everythink is ok, bike runs and drives great.. everything is perfect.. i have 1 more problem, but i will open new topic because it is with electrics..

Thank u, today new problems.. on this hose fuel is leaking, it just keeps going from that hose, but when i close it bike wont go.. and this is closed with something inside..

it was blocked, but now i unscrewed that, and bike goes good, but now it needs setting, it turns off in neutral, on 5-6K RPM it starts to moaaa and when I leave gas it pass 6k rpm and goes great.. Do U know original setup for carb? Thanks for helping guys!

i tried "infusion" but it is the same, fuel is leaking from small hose onder the carb, thas hose has been closed with some screw... i unscrewed that and fuel is leaking when i stop the engine.... and i didnt seen that filter in this carb.. the carb is Dellorto PHBN16

No difference without filter.. yes there is good flow.. i think choke is problem.. it goes good for 100m without choke and then i must switch choke, if i dont do that bike stops, and if i swittch it dont stop but it cant go over 4000rpm

The float is about 14mm, i think something is wrong with Choke but i dont know what..

I bought manual just now.. i understand what is float height.. i will check it tomorrow. Thanks!

Yes there is height, about 17cm..

With choke on it just stops, i am bad in english.. hmmm the bike turns off with choke on, i tried another carb, working carb, and i can drive it for 100meters and go to 6th gear normaly and after about 100meters it says moooaaaaa and turns off again.. with my carb it cant even do 10meters in 1 st gear... I really need to fix this..

Compression is about 10-11 BAR.. i replaced piston rings today, it revs great in Neutral but in 1st gear the top is 4500rpm.. someone have ideas?

I replaced them 2 days ago, but its same..

I have new problem.. Polini reeds, 16mmPHBN Dellorto, Iridium sparkplug,...The bike revs great in Neutral it goes over 12k RPM but when i want to go, in 1st gear it just Moooa and stops, bike start inmidietly on electric and again it revs good in N, but it cant go, on push start he can go in 1st and 2nd till 3-4k RPM, it is 10-20KPH, i dont know what is wrong with the bike... in gears it just sounds like "Mooooooaahhh" and stops, in Neutral is great, revs more than good, over 12.000-13.000 RPM..

I solved this, thanks for advice, I have new problem.. The bike revs great in Neutral it goes over 12k RPM but when i want to go, in 1st gear it just Moooa and stops, bike start inmidietly on electric and again it revs good in N, but it cant go, on push start he can go in 1st and 2nd till 3-4k RPM, it is 10-20KPH, i dont know what is wrong with the bike... in gears it just sounds like "Mooooooaahhh" and stops, in Neutral is great, revs more than good, over 12.000-13.000 RPM..
