If you want any of these parts you can have them for free. Just for the cause...... Pay shipping. These parts are off of a 97 M900, the one in the picture on page 7 of your thread here. I believe the belt tensioners would work but I really am not sure so you'll have to do the research yourself but for the price of shipping it's not a bad deal. Just PM me

rear pump, line and disc.





Rear axle, 38mm intake valves 44mm exhaust valves opening and closing rockers



cheers, Thirsty

Thanks for the offer, but after a little investigation I don't think I can make any of it work. The tensioners are pretty different looking from what I've got. I'd love the later style rockers with the clips, but from what I hear they need some modification to work in pantah engines, probably due to the vertical cylinder having the intake and exhaust on opposite sides as the later models. I really appreciate the offer though.

On other news, the tank and tail piece arrived from the UK (well, they're up in seattle, not here) and look to be just the ticket. I didn't realize they'd leave a window in the gel coat. Kinda cool.

I don't have anything to add, but just wanted to say I'm loving this thread. I can't wait to see what the finished bike looks like. Someday maybe I'll have the time/money and a great starter bike to do something like this, for now I'll live vicariously. Keep up the great posts!

I'm not sure what you're asking here... I've never seen a 907 converted to carbs FWIW, but of course that doesn't mean it never happened. It's certainly not commonly done though. I do know mine's still injected.

I finally broke down and ordered a cheapo soda blaster. I'm going to throw the engine back together minus pistons and valves, make sure it's well sealed up and give it a good once over with the blaster. I'll recycle the old gaskets along with some liberally applied silicone just to be sure I don't get any soda inside. Then I'll take it apart again to finish my rebuild. I want to get the cases cleaner, but I don't want to take the whole bottom end apart to blast the pieces individually. Any helpful words of wisdom or warning before I coat myself and my yard in baking soda?

One thing I learned doing a head and cylinder off my R80 is that even though the soda is water soluble it takes a lot, a LOT of washing to get it all off the metal. I found some white discolored spots on the Nikasil lining after I was sure I had washed it thoroughly enough and dried it.

Hopefully I won't get any inside. I have a big collection of rubber plugs to cap off as much as possible and I'll mask what seals I can with electrical tape. I'm just hoping it'll be enough to take off most of the flaky chrome on my covers.

They guaranteed it against damage from gasoline, ethanol, etc. Fiberglass tanks can be made gas proof if the right resin is used. Also, here in Mexico we don't have ethanol in our gas. That said, I still probably won't keep gas in it for more than a couple days at a time.

OK, I have the soda blasting equation worked out. As usual, things are just a little more complicated down in mexico. The first obstacle was finding a big enough air compressor as I don't have one down here and tool rental shops just don't exist here unless you want to drive a couple of hours. I ended up renting one from a construction company I've been working with. It's powered by a 150cc honda single so that means I can drag it out to a far corner of the yard to keep my mess away from the house. The next obstacle was finding soda to use. Actual soda blasting media (armex, etc) just isn't available here and the grocery stores only sell tiny boxes of baking soda for $3 each. Not an option. First my girlfriend found a giant food wholesaler that sold baking soda by the kilo out of their 50lb sac, so she bought them out of their remaining stock of 6 kilos. Unfortunately, this stuff didn't work too well due to the high humidity here. Even with a moisture trap between the compressor and the media tank, it still just caked up and refused to feed. I then checked out a safety supply store that refills fire extinguishers. They ordered me a 22 kilo sac of sodium bicarbonate fill for dry chemical fire extinguishers which as it turns out is a much finer powder and is treated with something to resist moisture to prevent it from caking up in a fire extinguisher and some sort of flow aid which keeps it from arching. Perfect. It flows well and never clogs up. I've blasted with sand and glass bead before, but never with soda. I was pretty amazed at how effective it is for removing paint, yet it still will not mark aluminum no matter how long you hover over stubborn spots. It did a nice job removing grease, dirt and road grime from the block, but it's not agressive enough to remove oxide and get down to white metal, but then again I don't want it to be that clean as there's no way I'd ever be able to keep it that clean living across the street from the ocean. The carbs came out especially nice. Enough talk, here be the pics.

One sorta 70% done, the other as found:



The second one taking a bath:



Top triple mostly stripped, bottom triple as found. I'm starting to think that maybe I should polish the triples rather than repaint them. Hmmmm.



The engine got reassembled with temporary red silicone to keep the soda out and tossed out in the yard to get the business.



Before:



After:



Before (don't knock my red silicone glob job, it's only temporary to keep the soda out):



After:



Before:



After:



Now that the block is done, I've pulled the heads and cylinders and will blast them separately once I get the damn tool to pull the cam pullies. I tried to do the wheels, but whatever paint was used on there is way too hard and though it came off eventually, it was far too slow going. I'll need to use sand or something else a bit more aggressive to strip the wheels and the frame.

Scratch that. Too many deep pits in the castings to sand out. Thanks, Italy. Fresh coat of satin black. Done.



Fork sliders stripped, threads masked, ready for paint.



...and painted



The bottom triple is ready for paint too, but unfortunately the fork sliders used the rest of it up.

Only on other people's bikes. I just do "good enough" work on my own.
