Ps You can take off the flywheel cover. Grab a hold of the flywheel to feel any movement. If you feel any up and down movement, you need new main bearings and seals.

The jet tower gasket can leak and cause all kinds of poor behavior. That`s the piece inside the carb with torx security screws. The original gasket can shrink. The mating surfaces are not very plumb. Some people have good luck filing the surfaces flush. Sometimes just a new gasket fixes the issue. You can also search you tube for ways to test your carb.

What carb is on the bike? Should be a pwk, but old enough it could be anything.

Connecting rod comes as a kit. But it is 400 dollars more for a complete crank.

So We were at a National in late 2004 in the states. A friend had a 300 pro. Just after getting his score card and starting his bike he broke that case right before our eyes. Luckily Dale M. the USA gas gas importer was in line with us. Dale ran back to his trailer, pulled out the case and a gasket and handed me the parts. I had the bike back together in 40 minutes. We all finnished on time and had a great weekend. We sure will miss Dale! Thanks Arnoux for hanging out posting and helping everyone!

Yeah, you guys are talking about two different types of events. Our local event does have pre entry, but you can sign up at the trials for the same costs. We have had portable toilets at local events for about 2 decades as the total people count is about a hundred. We are having a National next May. Already working on the sections. The Nationals thrive on having a real number of pre-entries, you can enter on site the day of the event, but costs a hundred dollars more! Security? You guys don`t live in the states. Even our Pastor at Church carries a gun under his Robe.

The std 300 Beta in stock mode is weak. Beta used to have a bunch of factory parts to make it zing. My son had a 2015 with all the goodies and it was a beast. On the other hand I spent a day riding Ray`s bike and it was a monster, but was quite fun! If you look at the stock plate on the left, you can see the witness marks were a few springs moved off center. Just because you use different springs does not mean they don`t work correctly. The Japanese put alot of thought in the aftermarket parts they use.

That is 'nornal' on a diaphram clutch! The oring should not go bad if you are using mineral oil. Must be that tractor lube!

You were repying to me, again! LOL The Montesa clutch has never been very good ever. But we all have opinions. You should know better. Don't you ride a TRS now?

There is a reason the hrc machines use a different clutch.

The plate holds the springs straight. They other wise rub on the towers. The springs are much lighter. Available from Webike.

There are springs and plate available which improves the clutch feel. of course it`s only available in Japan.

The top riders use x11's.

The michelin is the best, nothing wrong with the IRC. If you find an 803 buy all they have. the rest of us can`t find them. LOL The TL01 is crap I threw mine in the trash after one event. And Dunlop knows this!!!
