Also, sweet looking XR!

Thanks broski!

Make sure you buy the HALOGEN light one!!!! the cheaper one runs a oldskool bajonet fitting (same as stock..)

And make sure your stator can run it!


Tomorrow (today already, its 2.37 am..)is the dyno day.. wish me luck.. Hope the piggy will survive it!!!

And? How did the piggy fare on the big bad dyno?

Did you just do a baseline check for the hell of it, or did you take it to the dyno to finetune the carb and whatnot?

Piggy survived!

36Hp / 50NM
DIN power / DIN Torque.

With the open airbox it GAINED 2hp!!!!!

I adjusted the mixture screw a little bit since it was running a little lean, other than that just took off my airbox cover tape (had it masked till i'd get to the dyno).

With the the airbox "closed" it had a little dip @ 6800rpm but it was due to a slight too big main jet. with the airbox open it revved all the way up with no problem to 7300rpm.

When pulling the tape on the box I "lost" 1nm, but that could be due to acceleratorpump setting. The dude agreed that finetuning the acc. pump would solve that little loss.



Wiseco11:1
hotcam stage1
FCRMX40
Open airbox.
stock 2in1steel header

I'm pretty sure the pig will gain some HP when using an aftermarket header.

Depending on your source it supposedly made 43 or 46 hp stock

The specifications are probably exagerated, and maybe they mention crankshaft hp instead of rear wheel hp which would make a substantial difference, but how can it have 36 hp after these mods?

Yeah, the numbers the interwebs mention are completely stock too, so header & muffler.

I find it hard to believe that a high comp piston and aftermarket cam will make less power with the steel header than the original setup would have.


What's going on here fellas ?
Can anyone chime in on whether the original numbers were THAT much exagerated or not?

I can promise you a stock XR will NOT make anywhere near 43hp stock,

see this reply
http://www.thumpertalk.com/topic/252.../#entry2087191


And remember there are a LOT of dynos that are a little positive when reading power..

besides, its not the power it makes, its how you use it :)

Progress is far more interesting compared to peakpower.


also see these

does it make any difference what number the dyno puts out?
honestly?
if you NEED MORE POWER
get a modern bike with a lot more power bone stock
but will that make you faster?
and (to me) more important:
will that make you happier?


am in need of a spedo plus cable plus drive
maybe an original headlight cowling + headlight
and heat shield for the headers
for the 86 I am trying to restore back to it's original beauty

if you have something flopping aroud
and are wiling to part with it
without breaking the bank,
please
please

there are enough mutilated XRs out there
I am on the quest
restore them back to stock

I rode a 2001 Fazer 1000 for the last 6months, and yea, I do notice the power difference, but the XR is so much more fun to ride!!! peak power does not equal fun.

on the topics of sprockets....

greetings pals,

I am new to the XR600R community but i bought an 86 this past fall and have been restoring it and turning it slightly more supermoto-ish. I intend to do mostly street riding and i am switching to a 19" front wheel and a 18" rear.

is there anybody out there that could advise towards if any sprocket combinations?

I will be feeling it out this spring/summer when i get it on the road but i was wondering if anybody had any experience on the matter and could weigh in.

thanks kindly.

I'm not one of those 'pissing contest' guys that's all about having more power than the next guy and rubbing it in, far from it.

A friend of mine is like that, rides a GSXr 1100 and is all pissy about me not being able to keep up with him on the straights.... gee you think?!?
Gets all childish when I tell him he looks like a clown dragging that lump through tight corners
Atleast he's a good guy other than that...

I was just genuinely suprised to see how big the difference is between what the internet will have you believe and reality.

The articles Royal posted clear up some confusion.

I suppose the factory numbers would atleast HAVE to be crank hp's instead of wheel hp's to explain the discrepancy


I've had more powerful bikes aswell during the time I've had my XR, this is the one I kept

Welcome !

What Steve said

I run 15/42 on a 17" wheel, it works for me.

It's still a little bit buzzy on the highway, but I don't do long strectches of highway often, so this is a good compromise.
If you use an 18" wheel it should be even a little less buzzy
