Try to avoid the temptation of over-revving the bike. If your gearing is correct you should be able to use second and third gear for most corners and first shouldn’t be needed. It’s not quite as critical on 250s as the extra torque means you don’t really need to use first anyway, but the correct gear for your riding style will definitely help increase your speed. It’s pretty rare that you will rev out in top gear so use this theory to get your gearing sorted so you can carry third gear more often. Two-stroke 125s can often handle several additional teeth on the rear sprocket so that first gear is no longer needed on the track, and third gear becomes more useable. Your goal should be to gear the bike so you can ride it in this window more with fewer gear shifts and without the need to use excessive clutch. This can be critical on a two-stroke because they have such a small window in which they produce their best power.
It may allow you to run the bike jetted slightly closer to optimum without getting excessive detonation which will eventually lead to engine failure. It’s not cheap but will guarantee fuel quality, which can be more critical in a two-stroke engine.
If your racing is moving to a higher level and you are looking for a performance increase along with some extra reliability, it may be worth investing in some race fuel like VP Roo100.

Don’t go spending huge amounts on engine mods until you’ve ridden your standard bike with the right jetting, as you will be surprised. Don’t be scared to be slightly on the richer side when jetting a two-stroke it will work as a safety net for engine life and also keeps the power a little more rideable, especially on a 250. If you aren’t sure about it, either do plenty of research or, even better, pay for the services of someone who can get it right for you. There is quite a bit to getting a two-stroke jetted correctly. If you get this right it will change your world. STORY SHANE BOOTH | PHOTOGRAPHY MATT BERNARD Some riding and setup tips aimed specifically at two-stroke racers.
