XT600E wont go over 140 km ??? Help !!
Hi , I have a 91 XT600E done 40,000 + Km . It runs well pulls like a school boy! It will get up to 130 km and after a loooong strait I can get to 140 km !:confused1: I am running 16 frt and 45 tooth rear ?? , I have gone over everything I can think of from dyno tuning carbs dialing in cam free flow exhaust fitted a better coil . I have not been able to ride an other XT600E to compare,Am I expecting too much ?? How do your XTs go ? I,m not after a race bike but a bit more go would be useful in all the gears so if you can let me know that would help. Thanks

Original its 15/45 and top speed marked as 148km/h. Maybe you need to buy a R1 if you like riding from 140-280km/h

Looking at your problem.... it is not a problem!
130 Km/hr is already 80.778mph so... you are already achieving over the prescribed max speed limit in NZ tsk tsk tsk

It's a 23-year old air cooled single dual purpose. Exactly how fast do you think it should go?

Use the right tool for the right job.

Go 15 in front or 47 in the rear, it should help a bit.

Then he will get lower top speed, with the gearing he has its suppose to give more than 140 so its low. Maybe take a compression test on engine.

Speed?
If you want to go fast, 16 or 17 front, 42 back, but then don't take it on a dirt road in the mountains.

Ha Ha ! Thanks guys , I know its not a race bike but it just seams to run out of go a bit earlier than I thought it would of ? Top speed is just an indication of what it will do in the lower gears and who dosn't want a bit more go? I just wanted to know if thats all it should have, or if your similar bikes have a bit more go than mine, but it sounds like thats all I should expect from the old girl and I love riding it

Well i dont think its ok, with your 16 in front you should gain about 5-6km/h, and if yours stall at 130 its to early. Check your engine compression and your carbs diaphragm. If its taking in air true the rubber it will give you slow riding on high rpm.

Its good, have you notice if bike stalls when you get high rpm? Remove carb and check everything, included the needle filter inside. When my diphragm was not working i felt like i had half power on high rpm, i recomend change anyway when rubber is over 20years old its not smooth anymore.

140km/h is only 5700rpm on stock gearing. He will be able to rev higher with the bigger rear sprocket for added top speed, without being anywhere near the revlimiter.

Its different from bike to bike, a xt350 pulls to just about redline when stock, and need a smaller rear og bigger front, as it runs out of revs before the power is gone.

I never do high rpm on the XT to get high speed, this engine last longest on low rpm on al gears. If you set the 47 back you get about 8km/h less than with standard 45. And that is on 6500rpm.

MY 90 will do 100 mph. I had to switch to air pods and 135 mains in both carbs and raise slide needles all the way up. The biggest problem is the ignition timing. My 86 has a max advance of 36 degrees vs the 28 max in the 90. With the same air box and jetting changes the 86 will leave the 90 in the dust and has a top end over 100 mph. You willing to avoid deep water crossings, clean the air filter often and drop your mpg to 45 to go 100 mph? you cant have everything. thumpthump
