I dind’t really see this addressed yet. I just picked up a 2016 300 Factory 4T and I’m fitting the long range tank I got from someone. The instructions I’ve seen are all for the 2-stroke, the fuel line seems to have a bit of an off routing. Anyone here mounted one and how did you run it? thanks Mark

Mine uses a USB cable- it has some electronics inside it, I have no idea what they are. Lewisport reported issues with those- but worked perfectly for me. mark

out of curiosity, I did look up the part numbers for the 2016 and 2018. there is a change in number for the oil pump. I'm still not sure how that would help engine braking. I suspect sales staff not knowing, and perhaps the new 'twin spark' CDI making the change? Since I've been riding 2-strokes for years and like the minimal engine braking, I am interested. Mark

I see on the Beta website they say the 2018 has ‘larger oil pump for decreased engine brakeing’. hmmm- I seem to have trouble imagining how a larger oil pump descreases engine braking? Does it really work? or is the ‘twin spark control’ actually do more? Or is it all just hype.

I have a set of 40mm Marzhocchi forks on my bike (non-stock). It requires the ‘pin’ type wrench to remove the caps. Anyone know where to source one? Mark

I have a BTWICE cable and it works fine. I would have to check on the wire colour. But two go to power it, the other two interface. I don’t know of anyone that has made one, but a couple said they were going to try.

Thanks!

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.
