    Front wheel bearings for Tech Fork

    https://www.ebay.co.uk/itm/B20-157-Alternator-Bearing-Compatible-with-Mitsubishi-PFI-20x42x9mm/272382151055?epid=645265262&hash=item3f6b3dc98f:g:JbEAAOSwSYpZz41K:rk:1:pf:0 There what you need if you've done a conversion from Marzocchi to tech unless you change or machine the hub to take a 12mm wide bearing then you could use 6004

    2016 CDI

    Yes it's the map switch for dry and wet conditions, It does make a considerable difference I've found but if you really want more power swap it for the later Dual spark CDI and it really livens it up, Make sure to use Part no 6416 if you change it, not from the 18 onwards models.

    Scorpa 2018? Yay or nay?

    Cracking bike, absolutely the best machine I've ever owned and won't be changing anytime soon, On my second Factory model now, You won't be disappointed. Carburate absolute perfect out the box, No such issues like you mentioned, If any doubts give Birks a ring and he'll talk you through them.

    Beta 4t in Trial 2

    Probably because the CV carb is fine for 90% of riders, it's only the other 10 at a very high level that need the instant power that a CV carb can't deliver as the engine vacuum isn't great enough to do so, There not designed as a performance carburettor but there great for low end smoothness which is probably what Beta have aimed for a good clubman bike, There's nothing to stop them trying a Mikuni pumper and changing compression with titanium valves, CDI for higher rpm to work with the ti valves, different cam profile etc.. and get a top rider running one, It'd get the job done as there a great reliable engine, In my opinion Beta should be working on a special 4t to run in the Trial2 class. It's about time it was promoted more.

    Beta 4t in Trial 2

    Get a flatslide pumper Mikuni carb on it and it'll be right up there with the Monts

    TOM'S exhaust for 125/175 Scorpas...

    TOM's are one of the top companies in Japan for parts for the 125F, Not used one of there silencers myself but I'd be saying go for it, Or the Mitani is another good option, Best jetting I can recall is 102.5 main, 17.5 pilot, Forgot the rest of the settings.

    Tech fork on 2013 GG

    Does the 98204Y have rubber shields? I'd make sure beforehand, I had same problem on mine with a tech conversion, Used same 20x42x9, either that or change the hub! SKF produce them with rubber shields but there not cheap!

    Tech fork on 2013 GG

    If the bearings for the Marzocchi now are the 6905 you won't be able to simply swap them for 6004 as the 6905 are 9mm in width opposed to the 12mm for 6004, So you'll need a 20mm ID bearing with a 9mm width also

    Scorpa T-Ride 250F - Missing Carburetor

    The VHST 28 with the pump jet hasn't been available from Eurocarb (Dellorto UK) for a long time, You'll have a hell of a job finding one, I have two of them on my bikes, I know somebody with a brand new one if required.

    Showa Rear Shocker

    I used to run one on my Evo factory, Was very good, It would only fit with the bump stop at the bottom but it is very tight on the exhaust side, Like you say the reservoir wouldn't clear the swingarm if it was the other way up like the Monts are, They are adapted for the Beta as the Montesa is a different length, Beta is 280mm and Montesa is 265mm, Mine had different internals and the nitrogen pressure was lower than what Monts use.

    Scorpa 300 Twenty Taming

    As above I'd go for the Flywheel weight first and also the slow action throttle, I had a ride the other day on a 16 Sherco 250 & 300 & a 16 Scorpa 300, Both 300's felt far to powerful for me even compared to my 300 Evo, and I agree the revs do build up very quickly which is probably why you are struggling with grip, The flywheel weight should help this a lot, Also make sure the rear suspension is set up for your weight, This will also help with grip, Hope you get it sorted.

    Hard Starting After Big Fall?

    Is the fuel tap in the correct position? It should be facing upwards, If it's downwards it won't shut the fuel supply off when the bike is on it's side, It's an electronic tap, If the bike won't run right with it in the upwards position the tap has failed.

    He's after a 250F 4t, Not a 2 stroke.

    New Bike Rough Running

    Try a BPR5ES plug rather than standard 7, Engine runs cleaner, It may help improve it.

    Parkwood Off Road - Likely To Be Open?

    Parkwood Off Road - Likely To Be Open?

    Just sent a message to them on Facebook, Haven't got a reply yet though
  17. I suggest to put it on and see how you get on with it, Personally I prefer having a flywheel weight fitted, It only tends to be the top riders who take them off as they need the power much quicker, But having the weight on will make the bike more manageable to ride at low speed, Help stalling and not spin up as easily

    2014 Evo Flooding Keihin

    Sounds like the float needle has had it's day, I've had a few in my bike, If you need to tap the bowl and it clears, The needle will be stuck open causing it to flood.

    4Rt Rear Rims ?

    DID on most Monts, Apart from the standard 2014/15 260, Which are Morad.

    2014 Jotagas 300 Pinking?

    Pinking can be caused from a Lean condition, Causing the engine to run too hot, Check for air leaks and Try using a higher octane fuel, Shell V power is good, And also maybe some octane booster as well, And the low compression insert should help as well, See how you go on.

    Best 4Rt Exhaust?

    Termi exhaust is awesome, Very trick, Really light and sounds lovely, Not sure about Mitani, Never used one.

    2014 Factory Alternator Cover Gasket On 2013

    I don't think it will, As the old type plastic cover I think has a lip which pushes on to the engine case to seal, The gasket needs to be on two flat surfaces to seal correctly. The new 14 factory cover is completely flat.

    Tyre Pressure Trade Off

    It just depends on the exact tyre you are using, Michelin's you can run low pressure no problem, But with an IRC Rear we found you couldn't run below 5-6 PSI, Because when you hit a drop off the side of the tyre would open up and let air out, Causing it to go completely flat, Pretty poor for a trials tyre. Michelin X11 rear's you can run all day at 3psi. Stick with Michelin! Tried and tested.
