My son goes for a quick ride in the front yard, endos over the bars, throws the chain and breaks the bike! All this evening and we have a two day event coming up next weekend. The chain wrapped twice around the front sprocket. Removed the shifter and sprocket and all is good? Not. Now a knock from the motor. Ten minutes later, I`m looking at the top hat and all is good which means I have to split the cases in the morning, so much for the 5 other bikes I planned of working on!  I`m hoping it`s just the shift shaft or next weekend will be our first missed event this year.       Till tomorrow.

Rats! Probably would have never happened on the old TY350. It's too hard to get the rear end off the ground to endo in most front yards.

What do you mean "knock from the motor"? It is a gasser, they all knock!

Just ride it till it blows up. Everyone else does!

Had on shifter shaft broken from a chain brake, but that was obviously seeable damage from the outside. Let us know what you find

That's cold man, real cold

Does the knock go away with the clutch pulled in?You hopefully haven't damaged the gearbox but you may have chipped the kickstart gear when you started it and a piece is stuck to a gear somewhere in the clutch case.,which makes a knock out of proportion to its size .Worth a look before you go any further,you're going to have that case off anyway

 Thanks, but this is far from the first Pro motor that I`ve been into. It started from this.

 

 So I got going early this morning and pulled the motor with my son`s help.

 2nd gear is the only damage, put`s me in a bind for  our two day event next weekend. Hopefully have the parts Wednesday night.

Cope is right... Just think! You could be riding a sherco... Regardless it could always be sher... I mean worse.

 Normally I might blame the Pro motor, but a double wrap around the countershaft sprocket, binding both the main shaft and the shift shaft could break any brand of  bike.  For some unknown reason my son  has caused more damage in our yard than anywhere else. Plan to two day the parts in the morning, which gives me Wednesday night and Thursday night to make it a runner again for next weekend. 

Amazing how much force is applied when things come to a screeching halt!

 

You are lucky you know. I have seen much worse damage done.  .

Parts ordered and will be here Wednesday. Gotta love the American importer as he has always had everything in stock unless the factory was behind. By the way he will be the new TRS importer. Now if everything goes smooth, the bike will run like nothing happened. Ended up with a five day weekend to get my boy to the event. Helps that I work with five other trials riders!

I dont think parts will be a issue the coming years. (Im sure actually)

 

I have a spare engine myself, In case of big last minute emergency (remember now still got to prepare it, lol)

 The correct gears showed up right on time. This time tomorrow I should have a running bike again, unless I missed something..

It RUNS! All gears, and no unusual noise.
