Making an ag100 keep up with an xr250

[MarlinHemi]

cant find much on compatible exhausts but does anyone know of ones that will bolt on?

[MarlinHemi]

reckon an at1 yamaha dt125 exhaust would make a difference or make any power?

One that you make yourself with a little basic maths a few bits of 20 gauge mild steel and a welder

Hiya i own a 1999 ag100 and do a few rides with friends and i cant keep up withe the bigger bikes like xr250's (obviously) and I cant afford a new bike and wanted to know if there are any mods that will give me any more power?


Cheers

I understand your needs.
I have experience.
:
1.FIT NEW TYRES.
In any sport this gives the major performance advantage.
2. Strip the bike down to the beer essentials! ...to save weight and bulk.
3. Add new oil to forks and up the level to give you a bit harder suspension. Crank up the rear suspension if it has adjustability.
4. Try de-restricting your exhaust somehow. Take the baffle out or take the end cap off. Check for restrictors at the head port.
5. Clean your air filter and maybe drill holes in your air box for better breathing.
6. Check for restrictions in the carb and inlet tract. You may have to alter carb mixtures to enable your mods.
7. Service your bike. New oil. Look over it and tighten bolts etc etc.
8. Up the gearing. Bigger front sprocket and a smaller rear sprocket.
9. RIDE WITH ATTITUDE !!
"Your bike is fast and awesome !
Your mates are slow and so are their bikes "!
Pin the throttle and GO HARD !!
:
Works every time. ;-)

yip mx100 cylinder or just some judicious metal removal Rd250 reeds and 28mm carb.
then add a better silver plated big end piston with thinner rings etc
Only problem is then the AG gears are too far apart
Pete Sales was selling some bits a while back including I think a dt or MX100 bottom end with a semi tuned cylinder.
here is his trademe profile just ask him what he has.

so try that fella first.

I posted a few tuned port maps for them ages ago.

Only thing is then you still have crap suspension and brakes.
You would be better off to save and buy a faster bike, but not so much fun.


Make up a semi decent exhaust and it will fly

What tools are you doing the ports with?

What tools are you doing the ports with?

If you need to ask, you would be better off to get someone else to do it.
a dremel and a die grinder plus some riffle files
But you would be better off to ask Pete Sales as I originally suggested.
Its very easy to make it slower 1 mm the wrong way can ruin one.
On the other hand there are plenty of Ag100 cylinders.

I was hoping there would be some other magic tool that wasnt a file. What Im doing isnt really relevant to this thread but it is a GP100 I have been playing with, the duct work was easy enough with a dremel but just trying to fit something into the bore to widen the rear transfers is a bit of a mission.

Wouldn't even bother. would sell it and buy something older with more grunt.

Pushing shit uphill.

There is magic tools but they cost more than some bikes.

But what you want is a 90 degree.


Or heat file to cherry red, bend file, then heat file to red again and quench in dirty engine oil.
