    One for the anoraks

    Looking through the entry list for the SSDT the breakdown of bikes entered is as follows:- Beta 83; Gas Gas 52; Montesa 41; Sherco 31; Vertigo 27; TRS 22; Scorpa 21; Honda 3 and TBA 1. I don't know how this compares with previous years, but a healthy range of manufacturers represented. Isn't it funny the things you do when 'on hold' to British Gas?;

    Vertigo 300 sprockets?

    Standard - 10:42

    Throttle dust cover

    They're free with every new throttle, or can be purchased separately from Chris Pearson at Splatshop.

    Coolant change

    It is easy. All I did with mine was fill the radiator, before lifting the front wheel as high as I could to release air trapped in the water pump and its hoses. Then with the bike level I topped up the radiator again. Do not tighten the radiator cap more than finger tight. Run the motor until the fan comes on and check the coolant level again when cool.

    Vertigo map switch 2019

    Hi Stefano The 2018 DL Replica also has a map switch and your post made me sufficiently curious to consult the various Vertigo parts lists. Your bike has a V-1323 main wiring loom, and a V-1356 front loom with no mapping switch. The 2018 DL Replica has the same main loom, but a V-1409 front loom with mapping switch. The 2019 bike has a different main loom (V-1505), but uses the V-1409 front loom with mapping switch. All three bikes use the same ECU (V-1320) so in theory you should be able to buy the V-1409 front loom with mapping switch and 'upgrade' your bike, but don't hold me to it! Is it possible your bike only has one map installed? You'd have to ask the factory that one. Cheers

    jotagas 2014 250 mapping

    Like Huski says, but there's no earthing involved; just join the two wires together for the 'sunny' setting, or leave them separated if you want 'rain'.

    The gear lever travel on a Jotagas is considerable, far more than on any other trials bike I've owned or ridden. Provided your gear lever is still spring loaded and not limp and floppy it's probably normal. Turning the back wheel by hand to help engagement (with a dead motor) can you get all the gears?

    Gas Gas factory bike detail

    I agree, all the manufacturers, except Honda, sell a bike that is virtually identical to the machines the works riders use; the TRRS Gold being the latest example. As we all know Tony Bou is a brilliant rider who has dominated the sport for a dozen years and remains a difficult man to beat; so why impose a minimum weight limit that keeps his bike competitive by stifling the development of rival brands?

    But what is the point of other manufacturer's 'making the effort'; their bikes already weigh less than the FIM weight limit. Okay, so they can select where to add steel bar or lead weights to tune the balance of the bike for a specific rider's preference, but apart from Ossa and Vertigo's more radical efforts trials bike development has been static for years now. Maybe that's a good thing?

    It’s a lead weight to keep the bike at or above the FIM minimum weight of 65 kilograms that helps the hand made, hyper exotic factory Hondas compete with their mass produced rivals.

    Jotagas jtg 2013 WATER PUMP SEALS

    Unless somebody has blocked up the weep hole in the bottom of the water pump casing water will not get into the gearbox if the water pump seals fail so are you sure this is the cause of your problem? And if you do need to change the water pump seals then just remove the water pump from the clutch case. It seems you're wanting to make things hard for yourself.

    2019 Beta. Let the speculation begin!

    That's interesting and something I didn't know. I think it will only take another trials manufacturer (or two) to use FI and the others will follow suit much as they did with the introduction of monoshock suspension and water cooling.

    2019 Beta. Let the speculation begin!

    If Beta does use fuel injection on its 2T bikes it will be interesting to see if it benefits from collaboration with KTM to use injectors that fuel direct into the transfer ports as opposed to what KTM dismisses as the 'electronic carburettor' fuel injection systems used by Ossa and Vertigo.

    Head spacer

    I remembered that I have a head spacer from a 300 GasGas so tried to do what I suggested and it's not that easy with the motor all built up in the frame. The PCD and spacing of the stud holes does appear to be the same as the Jotagas. The head spacer idea predates the later two part head design and I agree with you that it's better to machine the insert especially if you can find data on the correct shape and volume.

    Head spacer

    A GasGas head insert won't fit the Jotagas. If you can obtain a disc type head spacer it should be easy enough to lay it on top of the head to see if the bolt holes line up, but if you use a spacer and low compression head insert won't it be flat as the proverbial ................ I presume you're using 98 octane fuel. Have you tried richening the mixture/changing the jets, etc? What make of carb' are you using?
