Hey Denis, Sorry for being late to the party I don't get on here very much these days. Anyway, I have a 2007 300Pro myself. Great bike. I've had several Pros over the years and loved each, although I have a particular fondness for the 300 models. I see you are in Moncton? Timely that I come across this, as our Provincial association, NS Offroad Riders Association (NSORRA) is working at this very moment on acquiring and building 1-3 trials riding areas!!, and putting on some events over the upcoming year, organized practices, competitions, and possible school. Drop me an email with your contact information so I can keep you in the loop. Joe

Yup. You can also clean air filters in any high flash point solvent (kerosine, etc). I'd also strongly recommend that after washing in solvent that you wash the filter again in nice warm water with some dish washing soap. You'll be surprised how much more dirt is released in the soapy water, even after a thorough solvent washing.

Alexei, First question I would have is what gearbox oil are you using? This is important because the fibre plates of Pros are effected by some oils and causes swelling and therefore clutch drag. You should use the recommended non-synthetic ATF (automatic transmission fluid). As for bleeding. Yes, they can be a PIA to bleed. Not sure of your technique but the best success I've had is using a syringe on the slave end and pushing fluid up to the master cylinder. Take the top off the master and let it overflow. It's messy, be warned. If it's particularly stubborn, I'll push fluid up for a little, then draw back on the syringe slightly pulling some fluid back...and often an air bubble as well. Now, when you changed the seals on the slave, did you make sure everything was surgically clean? Also both seals should be lightly coated with silicone grease. I've put in seals without the grease and had them fail almost immediately. With a little grease, and extreme cleanliness, they'll work fine and for an extended period of time. Hope these things help. I don't get on here as much as I used to so feel free to drop me an email if you have any more trouble. I've spent a fair amount of time on these.

I haven't had one of the Trials Ohlins apart, but have had many of the MX/Enduro ones apart. This screw does not seal the nitrogen charge on a normal Ohlins shock. It is little more than a dust cap. The charge is sealed with a rubber under this screw. Still shouldn't hit regardless. I'd rather replace the screw with a low profile bit than grind the frame. Bushing swap is the right solution though.

If your speaking of the air mixture screw, it's on the airbox side. Little brass slotted screw.

So long as the bike is pre-06 and not a Raga

Looks just like the one of Dougie's Montesa in Duluth a couple of years back.

I wouldn't chance it...those slave o-rings can be sensitive. You should be able to find silicone grease in any autoparts outlet. Heck I'd send you a blob, but don't think it would survive the mail

At the Supercross making a living

If 1-2 turns on the screw doesn't fix it, pick up the next size up pilot jet. I've found I can run one richer on the pilot on every Pro I've owned.

Don't let some of the stuff on here put you off. You'll see most comments are from guys who've never even owned one. Most who have have been perfectly happy. I've had every Pro since 2002 and haven't had any issues worth speaking about, aside from an ignition adjustment needed on my 2005 300. If you like the feel of the bike, buy it and hop on past all the neysayers with your front wheel held high

Don't hold back Ringo....tell us what you really think! Just when I was getting bored, leave it to Sendro and Tom for sarcastic relief

yup

I am going to assume the bike is running when this happens? It's kind of a "clack" sound...like you tapped the motor with a small hammer? If this is accurate, it's likely a lean condition at idle causing this. It is sort of "pinking", which is caused by detonation and is normally noticed most under heavy load and open throttle...sounds sort of like a bag of marbles being shaken. This too is usually a sign of a lean condition. If the noise your hearing is similar to what I described above, I suggest you turn the fuel screw (little brass slot screw on the side of the carb) out 1/2 to a full turn and see if it improves.
