125-200cc 275 hours on a 125 report...

Just hit 275 hours on my 2009 CR125, bottom end is still stock, clutch is still stock, latest piston/ring has 95 hours on it...

I decided to do a compression check since I was slacking on the ring replacement...

at 179.8 hours the compression looked like this. 175 lbs. Pretty good.

Here it is at 274.7, down 5psi in almost 100 hours. That is pretty awesome if you ask me, I think the lectrons clean running has a big effect on this. Also the Amsoil Interceptor works pretty good too.

For reference this what is was at 124.8 hours when I was having all sorts of plug fouling issues. 155 psi... I was running the stock carb and Klotz R50 at the time, this piston/ring had 88.7 hours of run time.


Here is a little video from this weekend, this poor bike just keeps on running. Such a great bike!



Later,

Awesome video,reminds me of Idaho.
What chainsaw do you have,how do you mount it and how does it change the way the bike feels while riding?

That is the MS170, it has one of the forkrack.com mounts with an extra strap welded on that I pin the bar of the saw to in two places and a bungee over the top to keep it from rattling.

Yes it affects the handling but you get used to it. My primary saw bike is my old faithful 2003 WR250f, I have been on it for almost 10 years. On that bike I have a MS280 and a different mount that bolts to the front fender mount and straps to the bike with nylon straps and a bungee. I need to redo that mount setup, it is not quick enough to get on and off like the small saw setup.

I spend most of June and July on the WR with the big saw so the 125 and small saw is like riding a MT bike.
Here you can kind of see the saw mount on the WR, another rider made a bunch of these.


Here is video from a couple rides back on the WR, with my friend Sonny from Denmark riding my 144. He went home and bought a TE250.



Later,

Love the vid like the saw set up youve got nice bike control even with it mounted hat goes off to ya.
Where is your camera mounted as thats a really good view of bars and track?

Nice work Jake!
140hrs on my 09 165 and I still dont even know what the clutch plates look like. Tough little bikes.

Thank you, that was my 8th ride this summer with the chainsaw after a while it just becomes normal. I was riding my WR one day last year with the big saw, cut out the one big tree I needed the saw for and ditched the saw in the trees. I made it 100 yards without the saw and crashed. :-)

My camera is mounted to the front chin bar of the helmet, it is by far the closest you can get to feeling like you are riding the bike.

Let me dig up a few pictures...







Here is a closeup...

Here is another one that doesn't show the camera much, but it is a cool shot other than the lazy leg...
