Thanks for all your hard work John. My son and I had a great time. Best trials I have ridden in years! The sections were perfect.

Hmm why would you start a thread that the sole problem is yourself? You lost it. The rebuild kit is the same kit for 90% of the bikes that year. Has nothing to do with just one manufacturer. Hope the kit fixes it, otherwise you will have wasted more.

Hate to say the shims vary bike to bike. Just did mains on my cota 200 no fun. There is specific measurements to come up with the correct shim pack. Best to find a true montesa man.

So, Cope is the bearing lubed some other way like the gasser?

Wow, my first thought is a bike rack on the back. Second thought would just remove the bars. Just a couple of eye bolts and something removeable to brace/block the wheel since nothing is solid in any rv.

Remove the clutch and check the top hat at the end of the shift shaft. If that is all you are quite lucky!

Dad of 2 has got it correctly diagnosed. After just seeing the same thing happen to a 2010. You need to have the tranmission inspected now before you actually start beaking gears and need a total replacement. Yes it will just destroy it self if you choose to ignore it. Out of curiosty is this the Econo model?

Just curious how many pro motors have you repaired since 2002? Do you remember the crap shift drums and all the plate changing on clutches the first few years? When was the last time you replaced a complete tranny on one? HMMM? It`s been about 90 days for me on a 2010. You just seem new or lucky.

The clutch always has a lip of build up on it. The drain plug will usually have a small amount on it. If you ever have anything bigger on the magnet then you could be in for trouble. Sounds normal for a pro motor.

They are as bad as you think. The 300 is the worst. Mainly the kickstart. We have six 2004 300 in the club. Three of them have never had a problem. The other three have all had the clutch cover break. Shift shafts replaced numerous times and of course the kickstart gears. Even seen problems with newer bikes, but they have slowly gotten better. On the plus side they ride very well, make great power and are light and inspire confidence to the rider.Reliable? No.

That was almost funny, I knew I used to were one. I have not wore one since my desert racing days. I rode trials before my go fast days so I never considered wearing one. I would try both ways. Actually I need a girdle or it would now take at least two belts! Any how to correctly ride trials takes alot of body input. (the new bikes make it so easy most new riders never learn proper body english) If you watch a rider with a proper stance they seem to over exagerate every movement. But also notice they rarely need to dab. Trials takes alot of range of motion that cannot be done with all the gear our go fast friends use!

The beta guy from north yorks is correct. But understanding how hard the cable types are to pull the best thing is quality levers and perches first. Secondly 99.9 % of all clutch arm extentions were with bolt on items that could be removed and or modified for the user. Changing the stock arm might not be the best option as all ty parts have become crazy money. Unfortunately I can not find a picture of this mod. John? Are you riding vintage, modern or just having fun? Great bike! Last month I rode a `like new` example for two days chasing my son. Still smilin` Ps part is unavailable . arm is now obselete in the usa.

You need to buy a rod kit , top bearing ,piston clips,main seals, center case gasket, base gasket, and clutch gasket from a gas gas source. The main bearings should be available at a better price. You did not mention year, but should be the same for all models. Not a cheaper way around it at this point unless your dealer can also do the rod rebuild. You could replace all seals, and other parts also but is just preventive for future use.

You can `save` the pads by burning off the oil.

did you say you sprayed wd on the brakes?

If it is a constant tick related to engine speed perhaps the primary gear on the clutch has picked up some debris. What happens is a piece off the half moon kickstarter gear travels to the idler gear then becomes inbedded into the primary teeth. It is an annoying sound once you realize it is there. It can be very hard to find, sometimes a magnify glass is needed and go tooth to tooth. I have seen this three times before, twice on the pro motor.

Thanks for that,Martin! Nice shot of Whaley on the Honda.

Without looking it up ,I want to say it could be center cases. I fixed one with jb weld (epoxy) and last I knew it was still working after ten years!

I always loved that bike, but had seen one corroded through. Pull the water pump cover off before purchase. The suspension front and rear was great for a bike from that time. There used to be some great video from jordi torres on that bike!!

Buy the 225 kit for the 125.

The newer gassers actually lube the main bearings from the gear box oil. Dad is more right on this one.

Have you ridden them, the 88 rode like a ty 350 (nothing wrong with that if you want) The `89 was the first water cooled (large) 90 (large marginly better. 91` green theme still big. `92 and 93 much more compact and actually the 94 was the best but now with the new gassers out was considered still bulky. I have owned quite a few, but the `93 was my favorite!

`92 or 93 Aprilia was a fun bike. The earlier ones not! The fantic would be easier parts wise.

80:1 fuel. 4-5 rear tire, 6-7 front. Beta had a good manual with weight versus settings if you can find someone with it.

All the magnets were good and tight your good. Just pointing out what goes on `em. Still have that strange noise?
