Sorry, I should have said I don't know what pads the ossa takes but I do know recent gasser with braktech brakes have pads that don't use retaining pins.
thanks for the replies, the reason I ask is I have both my own compressor and tyre changer. I find one trial hardly marks a new x11 so I have used the same tyre for several events always turning to the best edge and then refitting practice tyres in the same manner. I was interested to hear peoples experiences of pulling tyres off and refitting.
how often can a x11 be turned before the tyre becomes stretched or won't hold air. Interested to know because they can keep a good square edge on the tire when turned regularly but wondered will this affect the tyre in any other way?
That is not true Huski. The cylinders are not the same, the cylinder heads are not the same. The base gaskets are not the same, Only some of the pistons and little end bearings are interchangeable.
The friction plates in the clutch are the same dimensions, but the steels are not. Very very few parts the same in both motors.
That's interesting information. So for the sake of conjecture if I wanted to renew the clutch on my TRS Gold I could order the Kevlar plates the new gasgas use theoretically?
Hi Handyman, the problem may not be the shaft. At the right end of the shift shaft is a selector spring that sits over a sleeved washer with a pin through one end. I think this is called the selector positioner assembly in the parts book. The pin locates into the slot in the end of the shaft. When the gear lever takes a large knock, sometimes the sleeved washer is forcibly rotated and becomes out of alignment which then does not allow you to select gears in one direction usually. The assembly does not take too much to be out of alignment and may well look ok at first glance, the pin must be exactly in alignment with the integral tab that the spring ends locate onto. This is usually the first thing to go when you take a knock on the gear lever, worth having a look first before splashing out on a shaft. You can see this unit behind the clutch basket. Bye, Peter B.
As baldilocks has said the TRS pump is designed to let the fluid exit rather than enter the gear oil when the seal fails. Coolant can react with the plates and ruin the clutch also. I've experience both things.
I would be interested in hearing from the carb technician billy as to what is the best way to eliminate that lean spot in the mid range you allude to in your original post. I know this very same scenerio afflicts bikes with keihin pwk carbs gas gas and TRS to name two.
I have had everything apart from the scorpa and montesa. I spent 7.5k on a new TRS this year after trying most everything else which clearly shows where I wanted to put my hard earned. Factory Beta a great bike too! Everyone's position is different and opinions vary, all modern bikes are good.
The Dabster, I Keep re-reading your first line and I have to disagree, it's the rider not the bike, you just cannot buy experiance.
Your quite right, I meant to write that the other way! If you look at the context of the thread you will see that's what I meant to say. it is indeed the rider.
Generally speaking its the bike not the rider, up to a point! I have a brand new 19 TRS Gold and the bike is truly sensational in every conceivable area but there is a lad from my area who has actually won the Scottish Pre 65 and I have seen him ride the pre65 bike, suffice to say his skill level is such no matter how good the modern bike most of my peer group cant hold a light to him. The equation probably alters slightly where technically the section suits the modern machine more and that aspect narrows the skill disparity but as said previously the machine matters less than the rider IMO. In relation to riding gear Gearne boots are hard to beat as well as jitsie carbon helmets and hebo or clice clothing.
Don't touch the float unless you know it has been maladjusted. I had an 18 racing, albeit a 300 and I thought the 45 pilot was good with needle in standard position ( whatever that is) and I fitted the no.3 slide as opposed to the 3.5 it comes with standard. fine tune on the mixture screw think roughly a turn of the seat if you use a 45 pilot and possibly two turns of the seat with a 48 pilot and fine tune from there. The big thing for me was the richer slide. they run well on that.
I agree with intotrials, that's the three names that will be there at the death. Dabill for me has the confidence, he had it last year if not for the mishap, can't see past him but its a long week and early number days can have a significant effect. If it stays dry I would say Dabill, Lampkin, Price.
I think I should use a Montesa 348 for races then... It works!
Okay I'll try again..... the effectiveness of the original design has not yet been superseded in terms of performance, durability, cost etc etc and any other relevant parameter you can think off!
in (clockwise) richer, out (counterclockwise) lean. 1.5 turns out is usual start point if it needs to come out much more than that pilot jet too large and conversely if it's within half turn of the seat pilot to small (lean)
I really like the fact that the Vertigo guys are costantly improving their products, while some other manufacturers out there are still using 1994 engines
I wonder why they redesigned the clutch and the radiator, didn't they put a new clutch and radiator on the 2018 Vertical already, less than 2 years ago?
They must be really an hard working crew.... YOU deserve my money!!
There's a good reason why some manufacturers are still using 1994 engines. Rolls Royce still use the same fundamental aero designed jet engines from 1964 to transport people round the world every day for the very same reasons! They work!
It also has an interchangeable cylinder head with a higher compression insert. I had a 17 GP, the motor was quite nice, I changed the slide from a 3.5 to a 3.0 which made it run slightly richer.
1: you probably didn't pay £6399, especially in July with 19's a mere couple of months away - if you did then your dealer didn't help you at all and saw you coming
2: if your dealer is only offering £3500 then as mentioned elsewhere your dealer (possibly again) saw you coming and is fleecing you
3: think all the 18's now gone so you could see your rise a bit in value
I paid full retail price in July that's a fact. He gave me a trade in of £5k for a second hand TRS RR against the retail price. Not sure if he seen me coming or not but these figures are ball park from my experience. Do you know a dealer that would be more generous? I'd be genuinely interested. It was one random dealer offered 3.5, someone one of my peers dealt with before and he thought he would put a bit of business his way, I didn't speak to this dealer directly. As you say no more new 18's left so the price will no doubt rise again
I have a 2005 Ford Fiesta which we are looking to put a Dave Cooper bike rack onto the back for a supermoto pit bike. I believe that the nose weight is just over 60kg but the bike weighs 71kg. I am worried that because it is over the weight it will affect the steering of the car? Also if anyone has any advice or experience on this it would be greatly appreciated. Thanks
Hate to ruin your plans but I think it voids your insurance if the nose weight is exceeded in the event of an accident. Don't take my word for it check yourself, best knowing now hopefully it will save you a nightmare somewhere down the line.
Gasgas is identical it allows the oil to transfer through clutch back to gearbox in the gasser never seen the inside of a beta but would imagine identical role unless I'm wrong of course! It's a pretty big coincidence I think it's meant to be there.
I know this sounds stupid but you did slacken the clamp bolts that create the circumferential pressure on the fork leg? This makes a difference. The lower bolts hold the leg but the top ones' exert significant force, enough to put strain on the cap.
Sorry to hear this, I welcomed your input recently on this forum. It's always a time for deep reflection when mortality is questioned. Not knowing the nature of your illness I would say the vast majority of people over react and lose confidence which can have as much of an impact as the physiological insult. Modern medicine is one of the benefits of living in this period and multiple conditions that were once life limiting can now be safely managed long term. Take care, you'll be back...…. trials is one of the greatest afflictions out there lol.
