What size jets?
Running without fuel pump and bike performance not good.
Get 140 km/h max.
VEE,

Depending on exhaust can, you'll likely have to increase the main jet size. Many owners do not understand this and just stick the end can on without a thought to correct jetting.

My bike (slightly modded standard exhaust) will pull up to 164 kph (on the GPS so no speedo error). It just starts to touch max revs at that point. It will get to 150 fairly quickly, the other 15 takes a bit of a run. Your top box likely does not assist with top speed runs.

Start with standard jetting but be ready to increase the mains if it will not pull well at large throttle openings. Or replace the exhaust with the standard one.

You think pump wil make a difference to performance?
1 thing is that the vacium pipe on your left carb will suck in falls air and dirt when not closed off. so start by closing it off and do a test run.

With a aftermarket exhaust you have to re jet your carb settings, could be enough to just lift your needles but best to do a dyno run..
it could even be that you need smaller main jets because it breaths out easy now but is still restricted on the air intake..

And for the 750 riders, do grease up your air filter edge where it connects to the filter housing! it will leak fine dust/sand there! even worse than the 800 i thought was badly closed off!

@ Villguy, nice!
Was thinking about doing all that.. then i thought about it and bought a KTM Adventure 640
Love it when going on really bad off road rides..

But miss the BIG when its more easy, the BIG let you work harder and forces you to drive on technic in stead of just giving gas
So now thinking about a 750 '89 with the 800 engine and CDI and carbs, a good foam air filter, WP Extreme front and good rear suspension lifting it about 5 cm more butt leave the rest as it is qua weight and looks..
o and disc brake at the rear

haha yeah .. i was wondering why the hell i didnt just buy a ktm 640 adventure too. But then i realised how little this cost me if i lob it off a cliff.. i wouldnt cry (well ok maybe just a little)

kx500 forks - should fit, do as we have done and just change over the steering stem into the kx yokes - you will need to sort out some lockstops also. I welded a tube on the frame and used bolts to make adjustable ones

she just fired up by the way, for the first time in ... many many months.. and for only the second time ive ever started it haha, rather loud without the link pipe... obviously.. but still nice to hear it. Tanks on, seats on, new decompressor cable/lever on, hydraulic brake banjos on.

last little jobs and itll be ready for mot

Secondly, I'm guessing but I think you have the 1988 SR41 model (drum brake on back with the monster 29L tanks). She/he looks mighty fine.

I sold mine....

WD40, cleaner-diesel, oil and petrol fumes actually cure all illnesses in true grease monkeys bodies! speaking from experience

or...is it called addiction?

Now you know why I got myself LARGE end can. Still lot's of free breathing for engine but tolerable sound levels.

haha im just glad its up and running mate. Took me long enough.
Now im starting to fall for all the goodies i want for it
  • riky cross rallye bashplate for certain.
  • also want the seat covering and building up a little to stop it dipping so much.
  • still got this ktm front fairing to modify to get it on there, but i can do that on the side and just bolt it on.
just want to get out there and ride it now!!! but my mate wouldnt let me ride it away from his garage because all the neighbours would complain hahaha

i was totally amazed that it started straight up. I was expecting it to run like a bag of spanners but nope... perfect idle!

Good job!
Always a bit of scare bevore you push the button.. specialy when you had the engine apart...

And about loud.. try a open Laser and a fast sport cam.. thats f**king loud!
Those hard and sharp barks of a true Dakar bike
http://www.youtube.com/watch?v=IEZo7OMzRtM

Took the cam off, powerband changed to much..
more power above the 4000RPM but less under those RPM.
I love riding single tracks and climing and so on with the BIG more than just going flat out on the straight..
So missed the torque at low RPM.
But for fast flat out super motard style road driving it was gread
