80:1 seems to be the normal ratio for the majority of modern trials bikes. Also with GasGas Pro engines the crank bearings are lubricated with the gearbox oil, not the premix. Premix is only lubricating the piston and con-rod bearings

do you know what the previous owners were running for an premix ratio? Possible they were running a high(er) amount of oil which would foul the packing sooner than 80:1 OR it's possible the crankshaft seal has gone bad and is sucking in gearbox oil.

Yep, had a few fires in the silencer of my 2003 300 GasGas. Got hot enough it started melting the outer decorative plastic up by the airbox. Packing looks horrible too

Welcome, good luck

@mbeers6 sorry for taking so long to respond, bike maintenance has taken a back seat lately. I tore down the dog bones today. As you can see in the the VXB photo of the bearing there is no seal. Here is a photo of the same bearing installed in my dog bones. (Still a bit dirty, but hopefully can see it clear enough) note: it is a caged bearing and there is a rubber seal, I "persuaded" the original GasGas seals to be in place. It is a very tight fit and the seal does stick out probably a half mm from the dog bones. but after install in the bike, they don't stick out anymore. SQUISH!! ?

A friend in Germany mentioned the next 2 trials events have been cancelled. Events with more than 75 people are currently banned in their area. Here in the states I have not heard of any events being cancelled, but it may be a regional thing. MOTA doesn't have any events scheduled until May 17th.

I have medical insurance............. motorcycle doesn't............. but that's just me being a smartass

Of course refill with new gearbox oil, but be sure to run it until warm, dump that oil and fill with new. That will help get rid of any residual coolant in the gearbox.

Actually been a little while since I changed the bearings. If memory serves correctly, (this may be the issue and as I type this I may have remembered differently) the new bearings are just a touch wider than the originals, I believe I put in O-rings to take up the gap or I was "persuasive" with the old seals. I actually need to grease the dog bones bearings soon. I should take a pic and post it.

I buy these and re-use the old seals https://www.vxb.com/HK1516OH-Needle-Bearing-15x21x16-p/kit7374.htm

I really enjoyed his commentary through the sections, was interesting to hear what he was thinking etc..

my GasGas starting procedure - from cold choke on - from hot no choke Lean bike against appropriate item (tree, truck, garage, etc) OR have bike supported by skidplate (on stand, on a log, on the neighbors annoying bratty kid......) Stand on the footpegs Bring kickstarter down gently until you feel resistance From that location kick through with a forceful fluid motion - gotta get it to spin up quickly, but don't "stab" at it NO throttle Mine starts 1 or 2 kicks 99.9% of the time

In the video he says the "off road" bikes will be based on the KTM platform. I understood this to be Enduro and Motocross. Whenever Trials is mentioned it is specifically called out as Trials.

No new class, The best are the best and should be celebrated as such. World Trials is entertaining and amazing and does very little to nothing to bring more riders to the sport. (as far as I have seen) To even the playing field: Keep the dreaded minimum weight rule (make it realistic so that a standard production bike meets it) Bikes used in World Trials Competition MUST be a production bike - only "tweaks" available are existing aftermarket bits that are available to the public. and if those two don't cut it maybe cap the number of tweaks allowed, so the rider will have to choose between greatest suspension and maximum horsepower or some such. Just thoughts, I am not exactly adamant they will work, my mind can be changed. Discuss

spray carb cleaner around the base gasket to see if it is sucking in air.

good excuse for the 10 pound sledge................................. yes, I have done so for the Old BAGG

check your ground, I helped a guy get his Sherco running the day after he washed it. He rode it for practice, washed it, and the next day at the event it wouldn't run. Cleaned the ground attachment at the frame and all was right again.

those I ride with keep trying beer and liquor............. not sure how effective it is. We shall continue further testing

within MOTA (Michigan Ontario Trials Association) we have 6 Clubs, each club hosts 2 events per season. For a rider to be awarded season championship points they must work 2 events per season. This is how we get the majority of our observers, the members of the club will set up, run, observe their 2 events for the season. and then you ride the other 10. Season championship standings are determined by your best 8 rides. It seems to work pretty good. But you do not have to be a member of one of the clubs to ride the events. You will get a trophy that day (provided you finish in the top 3) but you will not be awarded season championship points for the year end awards.

I use a tree, rock or a log.......... if none of those are available, I have leaned it against a buddy's bike. Or just lay it on the ground, that's her happy place anyway. Spends enough time there

Reed valve is located between the engine and the carb. the valve portion is inserted into the engine. While the Keihin carb in my opinion is better than the Dellorto PHBL, the Dellorto is NOT a bad carb. as with any carb, keep it clean so it can do its job properly
