For easy country/road use you might get away with a reduced rear sprocket size, But clutching at straws really, a xr 250 is an xr 250, and a Yammy AG100 is always going to be an AG 100.

Yeah i know but honestly the gearing is already quite low

This modification will fix that problem

If you have the time an AG 100 responds to hot up quite well. BUT you will need to know what you are doing, try Gordon Jennings Twostroke Tuners Guide, old but relevant for that age engine (first built in the 70's). Larger carb, reeds, porting work (lift the barrel) and most important an expansion chamber. Done right you could be looking at around 20HP, probably more than the XR

If coin is tight new cogs for the sprogs will be the go.

Re gearing your bike with sprockets may be the cheapest mod here...Your bikes is a mountain goat made for carting fat Fred Dagg Farmers with home killed mutton and Tui beer packed arses over hills swamps and dales.

Up one or two teeth on the sprockets front or back may help give her 'Longer legs' while keeping her offroad charm.
Beware though no more billy goat hill climbs after this mod.

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.

can you not find an 125 air cooled?
Oh well if the price was right. I will have a look for a RD Yam reed Valve and reed Rubber unless you have you got any. MY RD stuff is at the old mans but i think there is only plastic ones there though you really need alloy ones as they are ment to be better.
I have a map of the Porting for the GYT kit somewhere I think. no clymer

The mx100 had a closer ratio box from memory.yes it did


DT100A MX100

1 3.18 2.83
2 2.00 1.88
3 1.37 1.37
4 1.00 1.09
5 0.80 0.96

Turns out it is a clymer hot up but i will post it anyway it is old but a start. The MX100 has a 26mm carb vs the DT100 22mm
The thing with Yamaha's is better parts from the hotter models can be fitted, but more so for the 125cc bikes.

Make up a semi decent exhaust and it will fly

Shouldn't you be getting your gp100 bucket racer on the track

[FlangMasterJ]

Get off and jog.

If you spent the time that you would need to hot this up, working for coin, you could afford to upgrade to a bike that ticks all the boxes. I understand the need to hot things up yourself however, so do what you need to. Should be a fun factor either way.

I know it's a shit old bike but you can learn a lot hotting up something like this and costing bugger all. If you fuck it all up, big deal, find another one and start again (but don't make the same mistakes). That's how we all learn't.

[MarlinHemi]

Thanks for all the replies to start off what would be good pipe for my bike?




to askor: dont have the cash to convert it and get to the track lol

[MarlinHemi]

That was my point. Did you not fully read my post?
Anyhow as said, MarlinHemi, there must be tons of info on here and google re getting a pipe to start with, or making your own?
