how much power?
 

How much power is the XT600E supposed to have? I don't mean in HP, i know its 40hp but how is it supposed to feel when accelerating?

The reason I ask is mine feels a bit slow but ok, when accelerating from 0 as fast I can down the tarmac road it feels on 3rd gear like its "just below the frontwheel-lift-border". Even on 1st and 2nd gear its not wild enough to lift the front wheel.

Its not that i actually want to drive on 1 wheel but looking at all those xt's on youtube it seems that they lift the front wheel as easy as anything.. So that just makes me wonder.

Does your x's acceleration fit my description or? Is it really supposed to be like this as a standard untouched XT600E ?

When i bought mine, it took some efford to make the wheel, lift, I dont know if I just got better, or the opened up exhasut and stuff like that really helped.

Ride in 1st. af 3000rpm, close the throttle and wack it wide open. That shoild get you in the air, if not, move further back on the seat and try again.

Other things to help is to use the suspension. You can ride at 4000rpm, use the front brake and make the front end dive, and get down to 3000rpm, as the front rises, wack the throttle up. Or you can give it just a quick wack on thr throttle, the suspension will rise, then "fall down" and as the suspension gets up.....Yep, you gussed it, WOT (wide open throttle)


You can also tighten up year're rear spring so it gets firmer, so it wont absord all the action going on when you try to wheelie :)

Enjoy, and be safe.

I know what you mean, from your description I think your bike is like it is supposed to be.

I have a TT600RE, it has the same engine as the XT600E 1990-1995, but a little bigger carbs.

It pulls ok, but feels a little “lazy”. Not much throttle response, probably designed to be “user friendly”. From memory my ’82 XT550 I had many years ago had apprx the same total power, but felt much more awake. It built power more quickly. Maybe the difference is in the ignition mapping.

My bike will not wheelie easily. It will wheelie in first on the throttle alone, but not that easily, I need to be aggressive.

In second gear I need to apply front brake aggressively to compress the forks and when the forks rebound, apply throttle and clutch aggressively. Timing is everything, if I don’t get it right the bike wont wheelie.

In third the bike will not wheelie at all.

They have a massive flywheel, so they dont build revs that fast, but hey do crawl along in gear, at idle :)

Thanks for replying :)

It sounds like my xt is "normal" in terms of power :)

It will be right dont worry about it and you can tell it has some torque you're prob just thinking it should be faster because its a 600, if you wind it up through the gears they do move a bit but I wouldnt worry about flipping it :)

Hello!

I am a proud owner of 2 bikes, XT600-2KF from 1989, and 1990, with total rebuilt engines. My bikes should have about 45hp and with a slipon silencer(as i have on the first bike) there should be about 2-3hp more, i hope. Secondary reduction ratio (Chain drive): 39/15 = 2.600 (2KF).
My eldest bike lifts the front wheel rather easily when I drop the clutch after shifted from 1st gear to 2nd gear. IF Im sitting as straight as possible and rev it rather high in 1st. My wheight is about 75kg. The bike is about 150kg. It does the same after im shifting down from 3rd gear to 2nd again, when I give full throttle and drop the clutch after a little practice! When thinking of the engines lengt of life this last manoeuvre maybe isnt just the best thing to do..
But there isnt enough power to lift when its shifted from 2nd to 3rd gear.

If the bike is supposed to be 45 bhp (manufacturers figures) allowing for production variation you can realistically expect around 40 bhp.

This figure is at the crank so you'll be looking nearer to 35 bhp at the wheel.

I'd expect an easy wheely in first - just snapping the throttle and a slight pull on the bars.

In second gear, a touch of clutch will be needed - or a bit of a bump in the road and a hefty pull on the bars! These bikes are not thorough bred performance machines, afterall!!!!

Carlhenrik, is your ’89 the last of the “first” generation of the engines (the engine without the oil line to lube the gearbox, CDI ignition )? And the engine in your ’90 -- has it this oil line for the gearbox and TCI ignition?

If so - How do the two engines compare in power and feel….??

35 horses on the wheel is about right, my 03 with 55.000km showed 34,6 on the wheel on a dynorun.

Was that stock?

The problem isnt that it should wheelie..its just that its hard to know if theres anything wrong with the engine or if its just supposed to be like that. The reason I brought up wheelie is that I used it as a reference point of power, thinking that a 600cc would be able to lift the front wheel(if should guess).

I've taken then end out of the stock exhasut, opened up the airbox, and used a foamfilter. Not sure if it helped, it did seem to me friskier at the low end.

Mine wheelies without hesitation, but i'be now added some bigger headers and a laser produro exhaust and rejettet the sucker. It wheelies even wit a 16 tooth frontsprocket.

If yu're worried, pay for that dynorun, you'll also be able to se air/fuel ration, and see it is rich or lean and stuff like that.

This is how to WHEELIE with an XT600 -

Expertly done I must say......:thumbup1:

Very nice XT too.

That's awesome :)

I went for a ride, and brought my helmetcam. I tried to show my xt600e wheelie, sorry to say im not good at holding it up.

The bike has been opened up and rejetted, gearing is stock.

Most of em is in 1st gear. just before, and after the roundabout, its in 2nd. Ii stand up, pump the forks, oull the handlebar and give it full throttle as the fork decompresses. After that, some 1st gear action again. No clutch at any time.

As I said....its been a while, and I suck at it, so bare with me. It's the bikes performance im trying to show :D

Sorry, no sound.... :( The camera does that sometimes, need to get it fixed :thumbdown:

Will make a better attempt later on.

Anyhoot, here it is:

Poor wheelie training

Thats a nice video

What is this? Intake manifold, but what do they mean "unrestricted version" "dethrottling supercharging power", is it a powerboosting product and what is that vent, is it gasoline directly into the intake?

Hey, as i read it (in german) its to replace your're intake rubber IF it is restricted there. Sometimes bikes gets restricted as a lerners bike. Here in Denmark you need to have had you drivers licens for 2 years, or be over the age of 21 to be able to ride with more than 34 horses.

Most bikes can be restricted, and often its in the intake. I doubt that this is a part that will replace a stock part, and give you mere umf. Sorry.

The hosething is just for venting ot something like that.

Thats how i read/get it.

G600: My 2 bikes are the same model, 2KF. And that model is suposed to have been manufactured 87-89. But my second bike are sold 90 in sweden and therefor it became a 90... According to Yamaha its a 89.
Yes i know, they changed the XT-model 1990.

I have tried an XT600 made 01, and I discovered a big difference, my 89 felt more powerful. The big difference is probably in the heavier wheight of the bike made 01. But this may not be all the difference!

I have heard from my local yamaha dealer that they may have changed the exhaust valves to another size(but I dont know for sure if it was 1990), so it could really be a difference in the XT-bikes engines whos listed to have 40hp against the elder ones who have 45hp. OFCOURSE on the crankshaft... Nothing else has been said in the specifications from yamaha.
Thats the only difference I know in the engines stock performance modifications. But it still could be some differences in the carburettors and different silencer-mufflers from one year to another AND in which country the bike has been sold.

Carlhenrik thanks.

From memory my XT550 I had years ago was more responsive and more “awake” than my current 2005 TT600RE. I suspect the ignition mapping of the newer bikes to be more “politically correct”, no doubt to fulfill some regulations…

The TTR600 (the last TT model before the TT600RE) had a kick start engine (not e-start like the TT600RE) and different ignition. Probably a CDI and not a TCI. There was a wire that could be unplugged (changing the ignition mapping) making the engine more powerful and responsive.

So… I’m 70% sure the newer Yamahas are running worse than they “should run” because of some regulations and retarded ignition mappings…..

The 500 and 550 are lighter than the 600's xt. They were build more as offroaders, where the 600's, especially the later ones, are dualsports made for a lot of street use. The 500 and 550 probably has a lighter swingwheel, making them more happy to rev.

With reference to the TTR and TTRE, I have both. The internal gearing and final drive ratios are different. The ignition is different, this is because one has a battery-one does not. The mystery wire on the TTR alters the ignition to affect noise and emissions regs, disconnecting it does make a small difference. The TTR does feel a little more powerful on the "seat of the pants dyno", this is probably also due to reduced weight, suspension travel and gearing. I run mine and the wife's (3x TTRE, 1x TTR). with airbox snorkel removed and Arrow paris dakar stainless pipe.
They are not powerful beasts, the only time I have ever managed to wheelie mine was by accident off road. That said, they will haul you and your luggage anywhere you want to go. I have run mine at approx 4500m with no no noticable difference in pulling power. with standard carb and jetting you should get good mpg too.
