Yamaha XT600E
 

Hi all,its good to find such a useful and interesting off-road biased site:thumbup1:.
I have an XT600E,year 2000,and i have been told it might have some form of restriction on it.I have checked all of the obvious things but wonder if anyone knows of any form of electronic ignition restrictions like a rev limiter wire or similar!!!
Any help appreciated,thanx.

Hiya & :welcome: to the HUBB...

In What way do you mean restricted? they arent real powerfull to start with!

if you want a FAST bike, get rid......

If you want a bike that will cruise happily at 65-70mph and will return 60mpg you have it.

If you want a bike that will go just about ANYWHERE,, you got it!

If you want a bike that will give you more smiles per mile and actually handle a damn site better than a traily should... you got it.

I regularly ride mine ( 1989 vintage 2KF XT600) beyond what I think it is capable of! It actually goes round the twisty roads here in Spain at a rate of Knots that has to be seen to be believed! The tyres are Heiddenau catspaw Trail and although iffy in the Wet.... are great in the Dry ( I haven't found the limit yet, although I do try... they have slid a little but never enough to make me scared.. :thumbup1:)

What is the top end speed on your Bike? mine tops out at just a shade over 90 ( 150 Kmh) although speed isnt what the XT is about it will outhandle a lot of other bikes on the twisty roads.

Hi,good to meet you:thumbup1:. I dont mean faster, i mean gruntier-torquier ! A few mates have ridden it and all said it should be and feel much more torquier and suggested it may be restricted in some way...:confused1:

Mechanical rather than Electrical?
 

Hi,
Maybe some previous owner has had it restricted to 33 BHP for the first two years of their licence - could be something on the throttle control cable or even in the carb.


After that, it may need servicing and or adjusting?

right, heres the simple fix!
 

The standard gearing is 15 tooth gearbox 39 tooth Rear wheel (15/39) 2.6

last week I changed mine. I put a 14 Tooth Gearbox and kept the 39 rear so the gearing is now (14/39) 2.78

Now that dont seem a lot, and it isnt, it is roughly equal to putting a 43 tooth rear sprocket on, it means the Bike will not have the same top end ( theoretiacally) all i noticed is 500rpm difference higher when cruising.

BUT now it accelerates like a ROCKET.... bags more grunt, :thumbup1:, even the odd little wheelie for fun and is a little 'buzzier' like riding a small 2 stroke.... Ha ha!....

Now that is a good idea Martyn!

I have thought about doing that!

The problem I have is that here in the mountains of S. Brazil my buddies want to cruise at 80 kph which is I think 55 mph and I have to either keep it revving high in 4th gear or chug in 5th gear which is bad for the gear box.
Does the 14/39 ratio allow you to cruise at 55 mph in 5th gear?

oh yes!
 

not a problem........ best mod and cheapest I have done to the Bike.
far easier than splicing a few links into the chain for a bigger rear sprocket and quicker to change too..... took me about 20 mins. :thumbup1:

Jst looking through the threads,

I have a 4pt 2003 with a 15/45 on, is this standard or higher geared? I know some say 14/39 is standard? the bike does seem high geared doing 5500 rpm at 90mph. Just wondering if I put a 14 on things might be a little nippier?

15/45 is stock, yes.

My 600E is old and tired, but will hold 55/60 mph easily in 5th gear, so it sounds to me as though there is something wrong. And I would call my bike very grunty/torquey - it's the bike's best feature :)

I'm not aware of any restrictor kits for the 600, but I had two XT350s in the past. The first (1986) was full power, the second was a later model (1992-ish) which was factory restricted to 19 bhp. The restrictions were a) a thick washer between carb and inlet which choked the intake, and b) extra baffling in the exhaust can. The first was easy to drill out, but the second was more difficult and I ended up selling the bike before I sorted it out. Remember, those were the days before online forums, when the only source of info was the dealer himself.

Worth checking the carbs to see if there is anything in there.

Ok just to confuse things, I'm running a 15 front, 43 rear sprocket and a 18inch rear wheel!

I find that the bike loves to sit on 95kph and gets 65mpg (4.3lt per 100K's). Anything above this is a chore and i find the noise and buzz annoying.
I weight 110Kg's (192cm heigh) and with my gear on board the total weight is around 290Kg's (143Kg for bike, 110kg me, 40Kg gear) fully packed for a long trip. This gearing is great for dirts roads and back tracks, where i can sit on 80/85kph all day and still get 65mpg:thumbup1:
