What did you do to your Gas Gas today?

[Selvagem]

Saturday installed two new tires:

In front of one Pirelli Scorpion XC Mid-Soft

Rear a Pirelli Mt 16 4.50-18.

Wow, how good to have new tires ....

Sunday was for fun:

looks fine but needs some stickers on it - maybe something to compliment the bikes sticker kit

Yep we all know they run better with lots of stickers on them.

New grips and a Motion Pro T3 throttle cable

Today I removed my S3 23oz flywheel weight in my EC250. I purchased it before I installed the rekluse clutch and it really smoothed out the power and would lug quite low without stalling. I loved it.

However, after installing the rekluse, I couldn't lift the front wheel with throttle alone since the RPMs wouldn't come up quick enough. I was having to muscle it up and got only marginal results.

Removing the FWW brought back the snappy response! It was wheelie time tonight...

I mounted up (no miles yet) my new Pirelli Garacross MT16 120/100-18. I went this route due to the favorable reviews I've read on it coming from the N.E. The rocks and roots are what we encounter here in bluff country and this tire still has good wrap around tread for aggressive corners. It's old school looking but I'm anxious to try it out!

I bought one.....

Removed the Rekluse Z-start from the '06 200. The plan is to install it in the '15 200 during the weekend if time allows. We expect a visitor this weekend; our 18 months old granddaughter is staying with us. That may limit available workshop time somewhat

I'm sure you'll like this tire! It is my favorite.

Out of curiosity, how much you paid for it? I wonder why this tire is produced at the factory of Pirelli which is 200 km from my house.

You probably paid less than I here ....

The 120 can be had on Ebay for $83.90 free freight. I got mine local for that plus tax to support my local parts guy.

Making a currency conversion I paid U$ 80.00. However, they have 23% discount due to an agreement with the store.

Have made a new bar end on a mini lathe

01 xc200

Last fall, I bought a '01 XC 200. I found myself wanting a light weight, easy to ride 2 stroke after having ridden a tough dual sport on my 450 4 stroke, that kicked my butt.

My first goal was to fix whatever was worn out or broken and having done that, I decided to do some other upgrade/repairs that weren't absolutely necessary, but I'm glad I did.

The pipe, a FMF Gnarly, was looking pretty bad. Also, if it had to come off, as in when I did the top end, it was tweaked just enough that it was a bear to get back on.

The old pipe.

Found this on Fleabay, NIB, $201.00 US, freight included.

The new pipe went on super easy compared to how I had to fight the old pipe to get it back on.

Next, was the clutch. It works well, but just had a little drag. Not a problem in most cases, but a PIA if you needed to restart in gear after stalling in an awkward spot on the trail.

Laid the bike up against the workbench and pulled the clutch cover and pulled the clutch assembly, including the basket & hub.

Found these notches worn in the clutch hub.

Found this oem clutch hub online, 94.00 US, freight included.

The basket had notches worn in it as well, but not too bad. I took the advice I read on this forum and files them smooth, being careful to remove no more than needed.

All other clutch parts looked good, so I took a chance on them.

Clutch re-assembled, minus the pressure plate and clutch cover

Clutch works well now. Starts in gear and can find neutral easily. Have only test ridden on the County road, a better test ride will have to wait till the local trails dry out some.

All in all, I think it was $300 bucks well spent.

Great job! It makes the time and money spent on a project more than worthwhile when everything works so good on your next ride.

I'm curious about what you are going to do with your old pipe. It's beat up and dented pretty badly, but it's not mangled or smashed flat.

Thanks Jim. I've read a lot of your posts, or guys who quoted you. Very informative.

I've done a lot of fabricating and welding in my former life as a truck & equpment mechanic & owner. I've made up the plugs for the pipe already and I've got a cutting torch, so I'll give heating and pressurizing it a try, one of these days. A good rainy day project.

Thank you for the kind words.
It sounds like you are ready. What did you use for plugs?

It took me twenty years to refine my set-up. During my initial experiments with my first version set-up, I shot a plug out of a Husky 430 pipe that went through my building's tin roof.
Some years later, while using a later generation homemade setup at the motorcycle shop, I shot a freeze plug all the way from my work area to the front display window, 100 feet away, when a bailing wire retainer broke.
(If it hadn't hit the ceiling on the way, I think the freeze plug would have broken that picture window. )

Here's my latest generation set-up. It's worked well for me for the last 15 years.
I took a 2" line pipe coupling (to slip over the header of the pipe) and near one end, drilled and threaded three 6mm equidistant holes to use the bolts for retainers, to catch behind the larger, flange part.
I use an expandable rubber freeze plug for the header end stopper, and a 2" threaded flat plug to screw into the pipe coupling to hold the freeze plug tightly against the header.
On the stinger end, I use a metal plumber's compression fitting that is sized to fit over and seal against the "stinger" of the pipe.
I fitted a threaded schrader valve to a bushing, to a bell reducer, to a pipe nipple, and put it into the other end of the compression fitting. (tighten the compression fitting.

For a thin wall pipe (Messico), I start with only 18 psi. For a heavy pipe like the FMF Gnarly, I start with between 35 & 40 psi.

Wearing gloves and safety glasses, with the pipe in a vise and aired up, I use a rosebud tip to circle the dents and work toward the middle.
I don't generally relieve any pressure on the pipe until I am finished, so the hotter the pipe gets and the longer I work, the quicker things happen. (I adjust what I'm doing accordingly.)
Don't get carried away and take out the small factory dent that helps clearance with the right radiator.

When I'm finished, I (now) always let off pressure at the Schrader valve before I start removing the compression fitting or the freeze plug.
I never take off my safety glasses until I finish.

I usually burn the spooge out the pipe before I start. It's amazing how much spooge can remain in a bike's pipe.

Good Riding and Wrenching to You!

Thanks for the write up, Jim. My set up for plugging the pipe is not as elaborate as yours. I'll revisit it when I get ready to work on it.

I used a expandable rubber plug for the small end and a 2" rubber plug for the big end with the bolt removed and in it's place I used a threaded brass truck Schrader valve. I then use the nut on the threaded Schrader valve to tighten down and expand the plug.

For safety, I've got plumbers strap fitted with the bolt(s) of the expansion plugs going thru the plumbers strap and folded back on the pipe and hose clamps holding the strap to the pipe.

I've not put my set up to the test yet. I'll revisit it when I get enough ambition to actually do the work. For now, I'm good to go with my new pipe.

Thanks again for stressing the safety issue.

How about some pics of your pipe repair setups. It may save a life!

Any using water pumps to repair pipes?
