Chain adjuster change? Hmmm, maybe this thing mounts a lot differently than I’m thinking. I dont’ see any picture with one mounted.

I see in the parts catalog a Licence Plate Kit- 007.45.074.82.00 Looks like a plate holder with taillamp and indicators. Is this really available? does it come with the bikes in Europe? I’m interested in one. mark

I don’t know abut the carb in this application, but I’ve used this tool on many bikes to successfully adjust the pilot screw. https://www.motionpro.com/product/08-0119

The 4Ride sounded really intersting- pretty heavy compared to my OSSA, but has other very good points. Doesn’t reall matter since they are not available in the States- maybe never? My Explorer weighs about the same as the 4RT260- and is street legal (well, has all the street legal stuff and easy to plate in WA) But no longer made and with getting close to 400 hours, seems a good time to look for another bike to add. Like any of us need an excuse? Haha

Montesa 4RT260 vrs Beta 4T I could only find pretty old discussions. I'm considering picking up a 4 stroke for my trail riding. I already have a great bike for that (OSSA Explorer) but it does have quite a lot of hours now and with parts probably getting harder to get in the future I'm thinking of adding a bike. The Beta 4T is lighter I know, great reports and look very well made. The Montesa has FI, reported to be very reliable and well made. Anyone have a fair amount of time on both and offer comparisons? (I won't be riding trials with either of these I doubt, but super tight 'pseudo' track I like to ride so much. I'm an intermediate trials rider, quite a lot of experience in riding in general, no longer want to go fast) mark edit: Does the Montesa still come with the removeable seat? I actually have the Beta 'long range kit' so know about those.

Great bikes, but indeed- not made at this time. I've had great results with my Explorer (over 360 hours). My Factory 300 has pretty low hours.

I have a video of adjusting the shifter spring.

I saw a magnesium case for sale. I'll try to find the link.

I messaged OSSA and they sent me the link of the above e-bike. They said they are still hopeful on the Moto-OSSA again, but nothing solid.

Yes, I understand that. But if someone was in the area I could meet up and do a TPS adjustment or the like. I was told checkers cannot ride to sections either, but will be transported.

I can bring my software/interface to the Kingman World Trial if anyone needs to give their OSSA a tune. I don't know my route back up north- so a possibility I could stop by if you live on my route. Mark

A heat gun to warm the linkage up can help with taking it apart. Some penetrating oil may help also.

Two of my four current OSSAs

Is it a rich or lean flat spot? You could try changing idle mixture and see if any difference, then raising the needle (lower the circlip) and see if it gets better or worse.

No- when you read the firmware version it shows it has a dual map. It doesn't not show details about how the map actually works (rich/lean/advance etc). Software is readily available, just the cables are not currently abundant. (Especially reasonably priced ones). Both ECUs use the same cable and software, just a different end for the 4 pin vrs 6 pin.

What is the engine number? Looks like someone already changed the carb- but I had excellent results with an OKO conversion from Mid-Atlantic Trials.

I ended up getting a different bearing puller and they pop right out. But I'll keep the square drift in mind. mark

I'm not quite sure yet. It seems map 2 is milder than 1. But I also don't know if the engine needs to be restarted after a switch- or it will do it dynamically. Or perhaps on this particular map, there is not much difference between them. It doesn't say in the software description.

I can't seem to find the info, so thought I'd ask. 2014 Factory 300. There are two maps- 1 and 2. What do the two positions do? Which is 'soft' and 'hard'? I see on some other maps they list which is which (or 'hard' and 'Road' etc), but the Factory one does not. Thanks Mark

I've had very quick results ordering from Trials and Tribulations (England) https://trialstribulations.net/index.php?main_page=index&manufacturers_id=7 Lewisport in the States has quite a stock also; http://www.lewisportusa.com/

looks great! How does it ride?

Where are you located? The bushing are easier to source in Europe it seems. Assuming you are buying in bulk. Trials And Tribulations does have them one by one. I was thinking the early bikes had bushings in the rear wheel? Did they change to bearings by 2012? I have the number written down someplace, but you can get the number off the bearing also. Mark

I made a very basic block diagram for the 'Super Easy Start'. I'll take some pics on the Factory 300 and where I put the battery etc. If I could find a decent source for the connectors, I could make these up ready to plug in. Ask any questions- I'll get the battery I'm using also. I only rarely charge it, since it only has a draw when the button is held down, it lasts a very long time. OSSA super-easy start.pdf
