Hi Jon, I probably got my post in while you were typing yours. Just to clarify, I bought my Raga 300 brand new and the settings I listed were how it was supplied. Like I said, this is the best carburated (if that's a word) bike I've ever had. But I disagree on giving it throttle while kicking though. It took me a while to figure it out as I used to start my 2001 TXT321 with little or no throttle. In any case, it costs nothing to try both techniques. Having said that, I have nothing but respect for your opinions. I've followed all your Gas Gas Guru technical articles for the past 10 years or more and you've helped me heaps. This is my chance to say thank you for all your hard work. Regards and thanks, Chris.

Hi Razorback, The standard settings for the PWK28 on your Raga should be: Main Jet: 122 Idle Jet: 45 Needle: JJH with clip in the middle groove Slide: 3.5 cutaway Idle Mixture Screw: 1.5 turns out Float height: 19mm from bottom of float to gasket surface (with carb inverted). I have moved my needle clip to one position richer to smooth out the sharpness that I had when rolling off the throttle. It runs absolutely perfect now. However, I find the bike likes plenty of throttle when starting (unlike the older models with the Dell Orto carbs). Probably about half throttle hot or cold. For cold starts, I pull the choke on and give it a quick kick. It will usually start first kick if I remember to give it throttle. No more than two kicks from cold. It will fast idle perfectly with the choke on and I do that for five or ten seconds then flick the choke off. It runs fine straight away whereas the older bikes would take a fair while to warm up before they ran any good. By the way, I'm at about sea level - but our winters are no where as cold as yours. Chris.

Hi Razorback, Don't be running 50:1 or even 70:1 fuel mix. It's not a lawn mower or motocross bike. At worst 80:1 but I've been running 100:1 in my gassers for years. That's using good fully synthetic oil such as Motul 800. Some people will argue this point but I ran 100:1 in my 2001 TXT321 for ten years before putting a set of rings in it. And that was riding a full day virtually every weekend. I'm running the same mix in my 2011 Raga. If you ever pull the head, or the exhaust header (or even the plug), you'll find there's plenty of oil in the cylinder. And the main bearings are lubed from the transmission oil. Any more oil than 100:1 and you're just clogging the exhaust. Regards, Chris.

I have the same bike (since new) and I love it. But the power is wicked. Your bike will have a black outer head. The insert you can see with 30T on it should be silver. That is standard compression. A high compression insert is red and the low compression one is black. S3 is fine - I understand the original head is an S3 Stars item anyway A low compression head and flywheel weight should make it into a smooth running torque monster. Be sure to let us know how you go. Chris Brisbane Australia.
