Started Looking at My Paso Project Bike

[paso750]

ok, the engine is back in the frame.
Tomorrow is time to check the swingarm. Now a stupid question. Today I was at a hardware store as I`m replacing about every single bolt and screw with new steel or stainless steel parts.
With dozenes of screws in one sack I was able to put them all back to their place, but I have 2 left. These are 2 very short allen bolts. They are even shorter than the ones in the swingarm at the bearing (although they`re same size). Anyone have any idea where they belong to ? I looked through the parts cataloguie very closely but couldn`t find them.

... :laugh: :laugh: :laugh: ... sorry, but that happens to quite many persons, if DONT make "notes"(to paper), when "open places"... Gerhard, this was ONLY little funny thing, i really didnt mean anything bad, as U know.... I was only joking now!.... :laugh: Let us know EXACT, what is thread, length, etc, so maybe then someone can remember, where those belong.... Remembering, that there are some locking screws(allen) in swingarm connection to engine/frame(for bearings), but cant remember lenght... Btw, there are NOT "stupid questions" !!!!!! (at least from You...)

[paso750]

you`re definetely right, Writing everything down is for sure the best. However I solved my little mistery. 2x M8 allenbolts 12mm (thread length) are for the swingarm bearing and the 2x M8 16mm allen bolts hold the headlight frame to the main frame.
No bolts left

Desmo,
have you already put hands on your swingarm ?
I removed everything I could but the bearings are stuck in place.

As first info:
the seals at the front say: INA 62 G 25-32-4
These have a metal ring like the steering seals
Not sure what the G stands for but the size 25-32-4 is used i.e. on 2001-2003 Honda CR250, 1997 CR500.
(according to what I`ve read "B1" would mean "with single sided metal housing, but it says G...)

the seals where the linkage mounts say: BAOF 20-26-4 Cortego C18
(BA = rubber shrouded, OF = without spring)
This size I could find on 1992 HUSQVARNA CR250, 1997-2000 HUSQVARNA TE610/570 swingarm

Pls note that the info on other bikes using the same size seals doesn`t grant that these are also the same type of seals (i.e. BAOF) one would need to check.

Desmo,

I was planning on removing the swingarm this weekend, but never got around to it. I was busy trying to clean and reorganize that room so I could get the rolling chassis in the house and out of the weather (it's on the back deck). I'm hoping to find the time to remove the swingarm this week.....

I've looked over the parts manual a few times to try to get a feel for what I'm workign with. I may remove the swingarm from the rolling chassis, first, then take the one off of the Paso Project. I'm hoping to not need much for it, so I can take it off, clean it, and put it back on in a day or two....then, time for another update.....I hope.


Edit - I pulled it off the bike when I got home from work, but I haven't inspected it, yet.

You should put this post as a new thread for swingarm seal/bearing info.....


I started looking at the bearings and seals on my swingarm, last night. I left the seals and needle bearings on the chain side of the swingarm installed, as they looked and felt good. I cleaned the spacers and repacked the needle bearings. The brake side was a different situation. The sealed bearings were locked solid. I couldn't get them to turn at all, so.....I removed the whole assembly of bearings and spacers. It ends up that these two sealed bearings are the same size that are used in the wheels....

From the old bearing....
SKF #63002-2R/S......If I read it correctly
20mm id x 42mm od x 16mm wide

The new SKF bearing would be #63004-2RS1

After replacing these bearings, I still need to check the three other sets of needle bearings and seals for the shock linkage, then......I get to reassemble it.



As also given in a thread about wheel bearings, here is the link to the USA SKF site for the wheel bearing specs...

man, what happened to your bike ?!

How did you get the bearings out ?
I got new seals yesterday. The bearings feel good so I`m currently not removing them, but I will have to later on as I have a brandnew swingarm and I`ll be in need of the inner spacers.
Also I`m not sure if I`ll go with the original or the 907ie swingarm as I didn`t have the chance yet to see how larger the 180/60-16 tire really is.

Monkeys with wrenches got to it! LOL :laugh:

thanks for the new thread. that ones comes extremely handy to me.
Currently I`m busy adjusting valves and changing the belt of my Gilera. I can say that working on a 1 cylinder bike is a pain in the a**. You need the small hands of a 10year old and lots of patience (20 screw only to remove the front and front side fairings - twenty !!!)

...and I was thinking that the Pasos had too much screws to get the engine...

My workfriend had Gilera RC 600 and he say, that driving with it was REAL BIG PAIN TO ASS !!!!!!!!!! Saddle was very uncomfortable and have to make pause every 100kms.... :funny: :funny: :funny:

Frankie, Pasos are VERY simple compared to ST4S..... :laugh: :laugh: :laugh:

I just wanted to let everyone know that I haven't forgotten about my Paso! I was waiting for some bearings for the swingarm and have been busy with house projects, the family, riding the other bikes when possible, and even did a SaddleSore 1000 (1000 miles in 24 hours) two Saturdays ago. It was actually 1102 miles according to my odometer and 19 hours and 43 minutes with my ST2 (and my wife on her Yamaha R1).

I finished inspecting all the bearings and seals in the swingarm and replaced two that were seized, last night. It's looking like the rear shock linkage is missing a couple of spacers/washers, but I can probably get those from my rolling chassis. I also broke down and decided to use standard 16mm bearings in the rear wheel to avoid having to use spacers with the thinner, 12mm wide, bearings that I had installed. To make matters worse, I discovered that I had unplugged the Battery Tender and the clock ran the battery down low enough that it will not recharge, so.....I'll need to buy another battery. If I'd known this project was going to take so long, I'd have just removed the battery and stored it with the tender on it.

I'm going to try to, at least, install the swingarm back on the bike and add an update to my website. My 748 hit 12k on it, so I'm getting ready to tear that apart for a valve adjustment, but I want to get the swingarm back on the Paso before I get too deep into the 748, so....

Hopefully I'll be getting an update on the Paso, soon! It's almost been a year since I bought it, and I'm getting closer to getting it back on the road!

Don't tell me about house and family problems...


I also lost my battery for the same reason.

Ok....I finally did an update on my Paso.....

[Desmo_Demon]

I FINALLY got around to running the rest of the fuel line and making some gross adjustments to the carbs to get it ready to (cross my fingers) start the bike. I put about a gallon of fuel in the tank......turned on the in-line fuel valve that I added........turned the ignition "on".....listened to the pump prime and start recycling back into the tank........I didn't see any fuel leaks and nothing coming from the carbs, so.......I hit the starter button.........it turned over about 6 times......and fired right up and started purring at 3000 rpm (I need to adjust that down)..........

I wrapped the throttle and it was VERY responsive!!!.........but after about 30 seconds, white smoke started pouring out of the exhaust.

There was a strong smell of burnt oil, so I figured it was either bad valve guides or the rings are bad. I guess my next step is to do a compression check and probably end up doing a top-end on the engine (new rings and a valve job).

The bike does sound VERY NICE. It purrs and has a really sweet tone to the exhaust with the Cobra F1s slip-ons on the bike. I really hate that the bike is smoking, but....on the bright side, the bike is back running after at least five years of sitting!

I made a short video of the second time I fired it up. I think this is the correct way to view it...

http://www.desmodemon.com/paso_started.mov


So.....everyone else agree that it may be the rings or valve guides? If I'm lucky, one of the valve guide seals that I replaced popped off of the valve guide.....maybe that will be the first thing that I do. That'll be easy. I just have to remove each valve cover and inspect the guide seals........This is kind of depressing. I was hoping I'd be able to enjoy the bike from this point on.


Edit - After discussing this with my father and a buddy of mine, I'll check the spark plugs, tops of the pistons, and do a compression check to determine which cylinder is giving me problems. With the amount of oil burning, it sounds more like stuck/broken piston rings, or probably an obstruction in an oil return. I'll try to do some diagnostic checks over the next few days.

Seems sensible. Also seems anything could be expected from that bike....

Good work otherwise and interesting read!
