I had never seen balance training like this. I think it would be beneficial for trials.

I've checked the coolant level and it's to the top of the radiator. Is there an easy way to check the impeller ? How can I check the impeller is working properly ?

Well, I changed the thermostat and the fan still runs as much as it did before. I would estimate it runs 60-70% of the time. It might be normal for it to run that much. I'll keep riding the bike for now.

These two videos cover the questions you ask and many other scoring rules:

I recently noticed that the fan on my 2007 TXTPro 300 is running almost continuously. It shuts off on occasion, but is running more than it used to. The bike doesn't overheat though. What do you guys think the problem might be ? Thermostat or water pump ?

I'd like to know how long it takes as an average to master balancing. I've been riding trials for two years and finally decided to work on my balance. I've been practicing pretty much everyday for a month, but I'm going nowhere fast. Will it take me months/years to get it ?

Wow, that was cool. Thanks for sharing.

I finally took the engine out of the frame and had the transmission serviced. However, I can't install the engine mounting bolts. The swing arm bolt and the front bolt go in without problems, but the bolt under the engine is misaligned by about 1mm and won't get through. I'm thinking to enlarge the tab holes by that much to fit the bolt through.What do you guys think, should I do this ? Thanks.

That was a great video. Thanks for posting.

OK, I got it out. I used a somewhat different approach. I cut the head of the longest bolt I could find with the same threads and used that to punch out the swing arm bolt. Thanks for the tips.

I'm trying to remove the engine from the bike and to do so I need to remove the swing arm bolt. I've loosened the 2 little allen bolts, but the swing arm bolt is in there solid. Is there a trick to remove that bolt ? I'm afraid to punch it out from the other end and ruin the threads.

I got it. It's easy once you figure out where the lock is and how to insert the screw driver. Thanks for your help.

Hi Jon, What about the hose clamps. How are they removed ? I tried to use a set of pliers, but I was not sure I was doing the right thing. Thanks.

What do you guys use to remove the brass bolt to drain the coolant on the gasgas TXTPro ? Thanks,

One more things. Does anyone know the torque specifications for the cylinder bolts and head bolts ? I can't find anywhere how tight they should be. I'm using 10 lbs/in for now.

Well... after strategically loosening a bolt here and there I was able to make it work. All is good now.

Is there a trick to install the engine mounting bolts ? After replacing the piston, rings, and installing the cylinder the engine mounting points are not aligned. I can't even bolt on the frame down tubes. It seems to me the only way to do it is to use some sort of a press. I really think it's humanly impossible to force the mounting points to align. I hate taking the bike to the shop to get that done. Any ideas on how to do it ?

Yes, that's exactly what I did. It took several kicks but it finally came off.

I can't remove the cylinder off my 315r no matter how hard I try. The cylinder head came off without any problem, but the cylinder doesn't budge. I've hit it with a rubber mallet from every possible angle and it hardly moves. I removed the 4 nuts that hold it down. Is there a trick to removing the cylinder or should I keep hitting it with the mallet ?

That's the wrong size. You need 39x52x11. Look at part number 10: http://www.apexmotosports.com/montesa%20parts%20book/f-6.htm I've also seen people run 38x52x11.

Is there a trick for removing that tophat part off ? It seems to be stucked in there pretty good.

I can shift some gears normally, others take a lot of rocking back and forth. When this happens the shift lever doesn't reach the end of its range of motion. It's like something is preventing from going all the way up (when up shifting) or all the way down (when down shifting). However, I'm always able to shift gears... eventually. The shifter always springs back to the neutral position. It's the other direction that has problems. It can't reach the end of its range of motion.

It looks like I'm out of luck and will have to split the cases. I'll decide if I want to do the job myself after watching the engine stripdown video. I'm a little worried since I've never done this before and I'm not sure I'll be able to correctly identify the parts that need replacing.

My 2007 300Pro has developed some difficulty to change gears that has progressively gotten worse. At first it was just difficult to up shift from 2nd to 3rd, but now it's difficult to up shift and down shift to several gears. I tried adjusting the shift lever return mechanism by turning the oblong piece behind the clutch basket to no avail. Some gears work fine, but then other gears won't engage no matter the position of the oblong piece. Is there anything I can check before I split the cases ? I read that there's a piece that can break and be replaced by just removing the clutch basket, but I can't see what that would be. Everything looks good as far as I can tell. Any ideas ?
