Thanks to all for the input.Woody,what type of shop did the machining of the linings? I have a new set that are to big to fit the drum,but wasn,t sure who to ask about turning them down or if that was even an option. I will have to look at what brand they are when I go back out,but I do like the idea of having them re-lined with a better material and then machined to fit. Lineaway,I still have the old pads as the new ones didn,t fit,a new cable and new amal levers.The backing plate was disassembled,cleaned and lubed-so I think I,m on the right track.I should add that this isn,t a MAR,but the older Plonker that came before it,but it looks to be the same front wheel.The carb is jetted pretty good and she will run right down to a stall and pick back up cleanly.The problem in my area is there are no true vintage trials.They just have a class for it in my district (17) and we ride the modern intermediate line. feetupfun,thats a good call.I always try to put it back together correctly to try and center the shoes and not bind the forks,but I never thought about that.

Is there anyway to get the front brake to work, or better yet,has anyone had any luck fitting a different front wheel? If so what was it from? It would be nice to fit a TY front wheel.

Either way you have built a very nice looking bike!

Go to Ossa world.com,then click on vintage,then click on microfilms.Then you will be able to click on MAR-suspension and see a parts break down of how it all goes back together.Hope that will help some.

1970 Ossa Plonker.Runs like a watch and will go up snotty hills like a 4T,but has REALLY bad brakes.

That looks like a great day of fun! I love those black AJS rigids in the first minute or so.They really would run right down to a wisper and pick right back up.Beautiful sounding and works of art IMO.Thanks for the video.

Thanks again for all of the input.The HFS looks pretty sweet,but I can,t justify the cost of them for how much I get to ride and compete.The way it sits,anything new would probably be a big improvement as the springs that are in it sag quite a lot just on it,s own weight.It feels like there is maybe 3" of travel when I,m riding it. I didn,t get to ride much this year due to a knee and back injury at work.A few weekends ago was the first time I rode it and my TY250A in the yard all year.I felt more confident on the TY and I think some of that is because the Bul just isn,t set up yet for me.

I have been driving a 92 chevy caprice wagon for the past couple of years.It rides nice,gets pretty good mileage and you can sleep in it in a pinch.My next vehicle will be a van though because a trailer is pain.No good way to lock the bikes up and one more thing that could break down and ruin a day of riding. The Nissan looks pretty cool,but being a vintage freak I really like that Dodge that Brewtus has.It would be impossible to find one that nice here in the midwest.A friend of mine has a sprinter van that is great.It drives pretty good,gets about 23 mpg loaded and you can stand up in it-which I really like.They just cost too much for me and aren,t cheap to service or repair.I think I like Lineaways idea of a stripped out conversion van.

I had thought about just gettig a set from Hughes(Bultaco Motorcycles).I just wondered if something other than stock or progressives would be better. Thanks for the replies.

I am in need of fork springs for my 199a.I have read that the Magical fork springs work well,but would have to do more checking to see where to get them here in the states.I have also read about longer fork springs from Inmotion.What is the reason for the longer springs over stock and are they a better or as good an option as the magicals?

Nice work,it looks great! That model is one of the best looking bikes ever built.

Most excellent job!!

OK,thanks again for all the help and advice.I really do need to order a shop manual.

Is there any trick to getting the screws out that hold the pressure plate on without buggering up the phillips head?

Thanks for all the help.I don,t have a service manual for it,so I do have one more question.Can I change the seal externally or do I have to split the cases?

I had the TY out today riding around the yard and it smokes pretty bad.The more throttle you give it the more it pours out white smoke and it will not clear out.The gas was mixed at 32:1 with a freshly cleaned and oiled filter.It,s only the second time that I,ve had it out since buying it back from a friend,but I know it didn,t smoke like this before. I,m thinking that it could be a primary side crank seal? Could it be worn rings? Too much oil on the filter or the fuel/oil mix?It does sit and idle good and I had no problems riding over logs behind the shed.On the plus side,I think that it killed off most of the mosquitos in the yard.

I came across this pic on the web.It is a pretty sanitary looking bike and I,m curious who built it.I like the way they did the rear frame mods and how the tank blends into the side panels.

Patrik.I have to apologize because I believe I have called you Paul in previous post. My book on 5-speed Bultacos calls for 90 foot pounds.I have mainly only worked on my Pursang and I tighten it to 50ft/lbs and have never had aproblem.

We have a trials next weekend and I will bring it up.The problem for me is not enough time to be real committed to starting something.I could help some,but betwwen work and kids I never now if I,ll make it to 5 a year or 1.Thanks for the input.

Man is that ow10 a great looking bike.I wish they would have put that into production! I will have to seach around to see if I can find any pics of it without the tank and body work to get a look at the frame and shock. Yes,build progress and pics would be much appreciated.

Thanks for the kind words and advice.A side pull throttle and chain guard are on the list of things to get.I can,t take credit for how it looks,my buddy that sold it to me did the work.I can,t thank him enough for offering it to me first when he decided to sell it.I did the airbox,wheel bearings,swingarm bushings,front sprocket and countershaft seal and steering head bearings. The airbox is from a M92 Sherpa that I modified.I had to shorten the fender some,but I did add a piece of rubber that extends down from where I cut it.

I finally had the 199a out for a ride around the "backyard" section so I thought I would post a few pics.I noticed a few things on it,s first ride.It likes to kick back when trying to start and when trying to skim the front wheel over a log it wanted to deflect off course more than my TY.I think that it could use some new springs because it sags quite a bit on it,s own weight or maybe a better pilot!

That looks like a good time Chuck and a good way to get the club some extra cash.When we use to have a decent VMX club here in the midwest they did a granny panty race a few times to raise money.It was fun and comical.I wish we had enough vintage trials riders in my neck of the woods to start an ITSA club.

Is the drain plug for the primary oil the bottom center bolt in the side case? My 77 Pursang was that way,but it had a larger flat head on the bolt.This is just a regular allen head. I also need to drain the gear box oil,but after reading previous post on the subject I,m a bit nervous that it will be buggered up.
