What did you do to your Gas Gas today?

Nice 750. Never ridden one. Closest I got was being lent a XJ750 to go pick up a part back home. Begged to ride his GT next in the garage, but no dice. Can't even remember the XJ.
 
winter jetting

got the studded tires put on winter fun! I hadn't messed with the jetting as much as I would have liked so I took some time today to make another adjustment.

AS: 3/4
pilot: 40
needle: NECW 3rd clip
Main: 180
temp: 30F or -1C
alt: 650ft or 200m
premix: 50:1

I was at the 4th clip prior to today and noticed it was taking a long time to warm up and run good, moved to the 3rd clip and wow! I can not believe the difference, warmed right up and sang in about 5 min. just a touch of spooge on the pipe.

I may try the NEDW 3rd clip as it may be running too good (id rather be a bit rich to stay on the safe side). it will be interesting to see how much I need to change it this summer once temps get back up in the 50 to 80F range (10 to 25C).

Today organised trail ride. Nice weather until it then dropped some rain, grass downhill got slippery and I had to park the bike.

Several ribs later, groan. Will miss the next ride which is a bugger. Pity was going great.


Seems a shame when we are free to ride and its summer.
 
Sorry to hear about the ribs. I hear applying beer to them from the inside helps the healing process.
 
Glad the wife bought a lazyboy recliner just before we got together. Problem is the cat thinks its hers.
 
Over the last couple of weeks:
- Put on AS3 kickstart lever to replace OEM that was getting dangerous as it had worn that badly that the lever was sloping down when trying to kick it. New lever works great, more confident now to kick it over with sandals on when working on it in shed.:)
- Had leak in radiator fixed by radiator repairer. The leak was coming from the LHS upper hose nozzle that had been bent in due to contact between the tank & the hose clamp screw. Rotated the hose clamp on reinstalling to give more clearance (I think Doc Brown made a comment earlier on this but I couldn't see which radiator nozzle was the problem - now I know:rolleyes:)
- Put in new oversize Vertex "C" piston at 150 hrs, now on third piston.
- Changed jetting for hotter summer temps, going a bit leaner from NECG 3rd clip to NEDG on 2nd top clip. For some reason it was running leaner at WOT with new piston so I have increased main from 175 to 178.
 
Rejet and a Bath

2011 EC 300. I've had her about 2 years now. Unfortunately, for over a year of that I was fighting through figuring out why she wouldn't run right. Turns out it was the reeds, but I created a few problems for myself in trying to solve that one, and it took a long time to get things straightened out.

BUT, she's ripping once again. I always felt like she was super smoky, and not knowing much about two strokes I wasn't sure if that was just part of the issue or what. I was running a 175 main with a NE3H needle in the third (middle) position, and a 40 pilot. Today (actually yesterday, don't hold it against me), I moved the needle down one notch (leaner). Mid and top felt pretty good, but I could tell idle wasn't great. No matter how I adjusted the air screw and idle, I couldn't bring the idle down. Again, not having too much two stroke experience, I didn't want to do any harm, but I noticed that if I 'half choked' the carb, it idled a little better.

So taking that into consideration, along with the fact that I leaned out the needle, I decided to go up one size on the pilot. I figured that makes sense since its cooler these days anyway.

Let me just say...
Damn.

Its like a whole new bike. Very responsive, wasn't smoking all the time, wasn't constantly loading up. I haven't checked the plug yet, but I suppose that would be a good idea.

Anyways, after a few hours of interspersed tweaking and ripping, it was bath time.

Now that I have that sorted, I think its time to fool with the ignitech cdi and try out some different maps. Anyone have any recommendations or custom maps they want to share?

Ribs still broken. Still sleeping in a chair.

Booger!
 
Gas gas Txt 28 pro saga

Not today but over the last couple of weeks I bought myself a Txt 280 pro off a mate.
Said to be in good condition but needed a shit tonne of work unfortunately so I?ve spent the last couple of weeks getting it sorted.

First ride out on it before I bought it I noticed the air boot wasn?t sitting on correctly so I fixed that trail side. Also found the rear shock felt harsh as hell and noticed the bump stop rubber missing. Everything else was set up wonky as with to much play and the rubbers generally required replacing.

The clutch was also set up a tad on the large side and cause of my nerve pain in my left arm I needed a softer set up.

Pulled it all down replaced a clutch plate with a thinner one - perfect now. Shifter and kickstart gears all looked mint.

Motor sounded nice and tight and has minimal blow by on the rings. Found the muffler had rubbed through so a little tig action fixed that and a couple of cracks too. Muffler packing long gone so that was replaced too.

Carby cleaned and set up correctly, front brake master cylinder kit replaced due to piston sticking. Front sprocket replaced due to hooked teeth, rear and chain on the way.

Wrapped the header pipe to stop the flesh sticking to it so easily! Much better.

Upon pulling the shock I have found it is a unserviceable Sachs so I took to it with the drill press and converted it over to a needle valve style so it can be re gassed and serviced easily. I have a stiffer spring on the way also. Bottoms way to easily.

Linkages were shot as well and when they were pulled I found there was something jammed in between the dog bog and frame and the frames tab had worn down to the bolt head. More tig action to build that back up.

Spun it round and got started on the front end, greased the steering head bearings, serviced the forks to find red powder coat all through the shims and valving. Real smart Marzocchi... Also repaired the broken check valve spring and trashed wheel bearings.

Seriously pissed off with the bike and purchase at this point I finally button it all back together to go for a proper ride and find out the front rim has corroded through and needs replacing. Yay!

Took it for a ride regardless and had a ball although it is very different from enduro and takes a lot of getting used to. The bike is so capable though and will climb anything with a tiny bit of throttle.

Front rim and spokes on their way.

I started trial riding about a year ago, wasn't enjoying the enduro so much after the move to NZ.

Trials feeds the addiction and is good fun. You should enter some events or you may find it will get a bit boring and you will move back to the enduro, that is what i found with the trials bike i had back in 2012. (most club events are far from the raga and toni bau level that scares most people away - lowest grade i could easily do on my enduro bike)

Also a lot more social as you get to meet and chat to people while you are waiting at the sections (I think this is the true reason for the open face helmets - easier conversation!!)
 
Yeah sweet I?ll get the thing sorted and look into it. There is a fair few of us in the group that have them so it is quite social at the moment.
Most of the time riding it I would be way more comfortable on the enduro but I?ve only been out on it a few times.
 
I had a TXT200 for several years, but after kids just couldn't find time to ride 4 disciplines and needed some money for roadracing. But find the right area and they are fun just trying stuff. Pretty crap if you have to ride them at any speed but that's not what they are about.
