    Unlike what was said, the needle for the main carb of the XT 600 E does fit that of the TT 600 RE. I ordered a kit from Aliexpress advised by someone that has a TT 600 R and the needle fits perfectly, just so anyone who's interested knows. The bike has actually more power on low and mid ranges, behaving better than before. No need to spend 10x more for an original part.

    I'm now trying to address one last issue which the bike already had before the needle broke. In 3rd, 4th and 5th gears (maybe in all gears, but I notice it in these three), when I open the throttle to the max (from 4/5 till fully open), the bike stutters and doesn't keep on reving/rpm drops a bit. As soon as I go back to 4/5 throttle, it starts revving up again. Any idea about what might be causing this?

    I've read about (and will try) taking the air filter out and checking if it improves, disconnecting the sidestand switch, buying a new slider/diaphragm for the secondary carb.

    As always, thank you very much in advance!!

    I dont think any one said the XT needle wouldnt fit? The difference is in the profile of the different needles. The factory uses specific profile to suit the characteristics of each bike. The biggest difference on the TTR is the difference in airbox size and the venturi size on the primary carb. Suspect it is now running richer at lower throttle sttings now. Check you r plug for colour after youve done a few kms.

    Did you check/ clean the rest of the carb when you had it out? Cleaned all jets? Removed float needle valve and check the cleanliness of the filter under the needle seat? sounds like it could be starving for fuel under full power ie running out of fuel in the float bowl

    Thank you for your answer. Did about 200km and the consumption is still the same as before I changed my needle--almost 6l/100km--, but I will check the spark plug's color, indeed. I will also check the filter under the valve seat, which in fact I did not check. Everything else was thoroughly cleaned with carb cleaner.

    Thank you!

    Hey guys, have a little issue going on with my 1984 model. Starts easy and runs great, as a rule. However, it seems as it warms up--or gets hot--the throttle response gets weird. It's as though the secondary carb. stops functioning.
    At first into the ride, it rips--great throttle response and power at all throttle positions. But in time. the throttle response gets sluggish, especially at smaller throttle openings. If you open the throttle more, the exhaust note doesn't change much and the bike doesn't accelerate properly then suddenly it takes off like it should. It never does this when first riding it, only after it has run for several minutes into the ride.
    The engine is built. 621cc, 11.5:1 compression, ported head, Web motocross camshaft, K&N air filter, stock carburetors with, I believe, stock jetting, stock exhaust with end silencer removed.
    Bike is a rocket ship when running properly. Probably only 4-5 hours of run time since complete rebuild.

    Any input is greatly appreciated!

    Thanks!

    Did you solve the problem? Check if the Carb slider is moving free, all air,vacuum lines are sealed, and the air cleaner clean with not to much oil(K&N type).
