  1. Maybe the risk of conntracctinng or passing on covid is low... But if something happens and you need hospital or other medical attention due to wanting to just go for a play on your trials bike you are putting an unnecessary load on the hospitals and health services... That's one of, amongst others the ACU as well as other bodies like football and things have probably stopped training sessions.

  2. Check the rear suspension dog bone bearings for free play... If they aren't regularly cleaned and greased they get rusty and bad leading to needing new bearings and bushes.  

    Other than that... Great bikes... I love them.

  3. Personally I'd fit a lanyard... And keep the bank angle sensor.  It's hardly considered heavy and if the bike does fall over for any reason and the kill switch/lanyard doesn't come off/kill the engine it's nice to know it will stop before any oil starvation... Leading to an expensive engine rebuild. For the sake of a few grams and not having to modify with the water tight wiring system I prefer to keep it in place and stay safe.

  4. £15 for a day of motorsport...you can't get much better value than that. 

    I think most people complaining about this kind of thing have very little input into the organisation and running of events and probably fail to notice that a significant proportion of the organisers and observers are in one way or another connected to youth rider.

    from having been event secretary, I can assure you at no trial I've been involved in have adult entry fees subsidised youth riders...it is just cheaper to encourage them into our sport to keep it going long into the future.

  5. It will be the throttle position sensor in the throttle body.  basically as they get worn the throttle sensor will go past 100% and 101% doesn't compute in the ECU so it causes the fault you described.

    Easy solution is to remove the plastic cover off the side of the throttle body and put a very thin shim under the wide open throttle stop, bringing it back to with in the  0 - 100% limits...much cheaper than buying a new throttle body.

    I've had this on one of my well used 4rt's and have come across it a few times.

    Hope it helps,

    Matt.

  6. Give it one or two slow kicks with the throttle half open, then kick it again with the throttle completely shut and she should purr into life. 

    I believe they need the fist two kicks to prime the fuel system.

  7. Info is on the todo trial website,

     

    Well...just stickers and a brake pedal form the outside and the usual update to suspension tweaks and maps.

     

    Interesting that they changed the piston design and added an extra piston ring (I think this is what the translation was saying!) moving from 1 compression ring and 1 oil ring to 2 rings and an oil ring.  Have people found issues with the 2016 300rr's...do they start to rattle from the piston end sooner than the 260cc bikes?  The standard 260cc bikes have 2 rings and 1 oil ring.

  8. Trials bikes are exempt from ABS.  The new regulation is Reg 168/2013 as ammended by 134/2014 and under Annex VIII...it confirms that L3e-A1T, L3e-A2T and L3e-A3T motorcycles are exempt from the mandatory fitment of ABS...L3e-A1T, L3e-A2T and L3e-A3T all relate to trials bikes.

     

    FYI - this also applies to enduro bikes as well.

  9. I had that exact same problem on my 2009 4rt, turned out to be the throttle position sensor in the throttle body. I removed the cover and made a small shim so the throttle went to 99% only and it solved it...saved replacing the throttle body. My assumption was that the TPS sensed 101%, and ecu decided that isn't possible so gets its self I a bit of a twist. If you can borrow one maybe try someone else's throttle body.

    Hope this helps.

  10. It's not just about length, you need to know if the spring rates are different otherwise it could go coil bound and lock out before hitting the bump stops.

    I'd recommend fitting a firmer spring though. I'm the same weight as you and fitted on to my 260 repsol and it made a great improvement, I wish I'd fitted one to my previous 4rts.

  11. I had this on one of my 4rt's, the only problem I have had in 9 years of 4rt ownership.

    Turned out to be the throttle position sensor...basically it will read up to 99% but when you go to 100% the sensor will loose its signal and the engien dies.  because it looses its signal it will cut off the fuel.  when you back it off a fraction it picked up again.  You could try another throttle body...or maybe try and insert a stop inside the cover where the throttle cable goes in to stop it at 99% so it cant go to the point off the sensor where it looses it reading.

  12. I'm looking at getting an exhaust for my 4rt, just wondered what people think is the best option. I'm looking at either the mitani or termi systems.

    Which is lighter? Which gives the best performance and which sounds best?

    Cheers

    Matt.

  13. My mates had their bikes stolen last night.

    2011 gas gas 300 racing and a repost montesa.

    The montesa is quite distinctive, it's a 2008 fitted with a Mitanni front pipe and silencer, anodised gold sump guard, swing arm cups, fork yokes and wheel rims with the back one being machined out works style. It isn't the standard montesa gold, it is the lighter TRW gold colour.

    Keep your eyes out and let's keep these type of people away from our sport!

  14. I'm thinking of putting a 280cc or 300cc kit onto my 4RT, other than changing the barel and piston are there any other mods that need to be done. I think witht he 280 kit it is just change the parts but with the 300 you need to modify the crank cases, is this true?

    Also will I need to put a programable throttle body on with a different map in the ECU?

    Matt
