chewy

There are only four nuts holding the barrel on, from memory you would have a tricky job getting a socket or torque wrench on to them, even a ring spanner, think they are 12 af nuts, Engine building first rule cleanliness is next to godliness!. May be wise to check exaust packing is good also before lowering compressions and messing with port timings. Chech out Beta forums also good luck.

A good idea only caveat to bear in mind is the (now disapearing) deep pockets of trials riders! Good luck keep us posted. He may have problems with insurance but there may be ways around this with practice day permits under "cover" of ACU club.

I remember seeing on here several times to check the earth of coi? electrics? up under the headstock area; maybe worth a look. I also wonder about fuel/Sherco it does seem to me they are the most sensitive to fuel variations and ours is certainly different to Europe. Anybody technical enough to go into bernoulies equation re the inlet system.

Wellcome to trials plenty of clubs and events around Bristol but you 're quite right not many are computerate you should google Wessex CTR ACU Twittering, there is a site run by Frank Sweeting who is moving our Centre "stuff" from a paper gazette to online, at least you will see some points of contact and what's on locally, Also for you ?beginers there is AMCA club Bath Classic Motor cycle club they run for classic bikes but will let over 40 years old on a mono ride (if that applies to you?) and thier trials are pretty easy. If you need any more local info or can't find it PM me.If you treally want to get involved the centr board meeting(you could read that as Bored) is at Warmley community Ctr. every first teusday in Month c. 7.30 for 8 and most clubs in the ctr. meet first thursday in month often in a pub!. If you find anywher good /free of hasle to practice PM me and I'll come out with you (practice land around Bristol is very tricky) all best Chewy

It's a ruddy nightmare I posed same problem day before you may be worth looking at some of the replies ther. I'm currently waiting for MCE to come back with half sensible price they had more than dounled renewal on a 1 year old Beta. Doodson wanted 260 od quid, Biggest problem is that the Association British Insurerer (ABI) have not classified evos into a number category. If you have a rev or earlier model compare the Market will turn up good price for you. Best I got for 3er PF7T (not in competitions) was

Thanks guys its all a bit confusing Janet was/is with MCE with her 200 beta she's over 50 no claims ever secureest bike store possible etc etc. They have practically doubled the premium for the renewal. Bennets and comparison people may be worth another try but it seems ther is no ABI code for EVO's thus making it more difficult to get quotes. Just keep on plugging away for time being. cheers

I just had to read this one (as a manufacturer of footrests) I was going through my bits box the other day and found some hangers which I think are for Mont 315; you can have them ( if you send a jiffy bag or pay for postage)if I can find them again. Let me know if you're interested.

Just phoned Carol nash to get quote for Beta Evo and they declined saying insurers dont like field/monkey bikes because they get stolen a lot. I thought thats why we insured them!; however has any body got best deal recently on TpF&theft insurance for EVo?

The design works if the band is fitted properly in the first place. I think that is the key phrase, since my rant and as the shops are all closed I tried putting a wind or two of PTFE tape under EVERY spoke nipple and took the opportunity to check out the trueness of the rim ; it was 6mmm out of concentricity and 4mmm out axially with as others have noted a big flat at the weld. I have a ring roller and have considered getting a decent rim profile extruded making hubs etc etc. Literally to RE invent the wheel...... progress eh.

Interesting ; Most centres have a rider grading system which basically should move you up a class when you start winning or thereabouts in you current class. However we have no national grading system and most centres have similar but different systems ( the usual problem of finding a volunteer to do it arises). I have a mate who has been a novice in our cntr. (which is not known for it's riders abilities) for 40 years, he has ridden just about every trial there is to ride in the UK and plenty abroad, but he's still officially a novice. so the distinction between beginner,novice, clubman expert etc. are just relative to ones own "bubble"/ area of activity. As we are not a big earner ( perhaps that an unfair jibe) for the ACU and the logistics of implementing any national even rational scheme seem remote. The bottom line is that it's up to your own conscience when you start winning pots as to how you "play" the game. Most folk soon recognize the big fish in a little pond and it is very easy to be a little fish in a big pond if you follow my meaning. Take your pick as to how you want to be "known"

Don't know how to or if this is correct place but have set of regs etc for new 3 day trial in France (Massiff central near Rochepaul)My link Early June have ridden in that region before is fantastic countryside.

Just for clarity I am putting this tyre onto my missus's bike and hers on mine to check it, air bubbles coming out of several spokes speak for themselves, implicit in my question was who specifies what should be fitted in order for it to work? and who ensures that the correct part is fitted properly? It certainly shouldn't be me but as I am a doctor and I've had a good look at the problem I could make a better solution with a stanly knife a sheet of rubber and a tube of superglue, when you pay good money you expect at least a reasonable product.

Following the topic on IRC tyres going down; I would like to keep folks posted with my recent experiences, /I have to qualify my observations with a bit of bulls*it I have been a qualified Mechanical engineer with a list of letters I could put after my name for 45 years about the same amount of time I have been riding trials bikes so I do have some idea of the difference between sh*t and pudding. Ok rant on; I bought a new Sherco in October and before using it fitted an IRC rear for the going around here. I have entered and ridden in 3 events since then and pottered in the garden a bit. I would say no more than six hours running time with some of that waiting in queues I am of an age where I don't thrash at anything. I have had to retire from all three events due to rear tyre deflating (but only when in useit will stay up for weeks on the stand in the garage!), I checked all spoke tensions after first outing blew tyre up and put it away. Anyway long story short.end today I got through 12 whole sections after having "unfrozen" the carb before tyre deflated and came off the rim. I have just cleaned and had it all apart refitted and checked and air is p****ng out of several spokes so I had a close look at the rim tape. It was clearly not fitted properly in the first place and of course it has now taken a set so it will need to be replaced. However my main gripe is who calculated/designed the fit of the rim tape and who fitted it; the "seat " for said tape is 26mm wide X 4mm undercut (if you have done this job you will understandthat the tape is supposed to fit into an undercut in the rim. the tape fitted from new (by Sherco) is 32 mm wide by 2.1 ( Iwould venture to say it started out at 1.25 X1/8 inch)so there was no way it could fit properly in the first place. Is it standard practice to allow the customer to fault find?

No your not alone , music makes a big difference to appreciation of subject matter problem is that it is always too loud in the mix.

If it has ever kicked back you can retard it a few degrees and soften it up as a newcomer to Sherco's it seems they are all running too advanced;; too snappy, stall easy,run lumpy on tickover, kick back. Do they set them up like this to help run a bit cooler?

I've had one go down twice in last two trials (it stays up when you don't need it to!) As my bike was brand new and I had changed from Michelin (which I keep for other riding conditions) I put it down to tyre not seating on rim very well, however second time it went down the whole lot was covered in mud & muck and I noticed bubbles at a spoke nipple, checked/ corrected spoke tensions and am now waiting for trial test; third time lucky? (I.ve had it at 4psi for a week no change) sometimes these things are sent to try us! Certainly the IRC are more prone to coming off the rim than any other and they don't last (as) long in rocky conditions but as you say they are best in mud and roots.

It must be worth a look at the flywheel key, was it prone to stalling ? did it ever kickback? did it try to rotate rear wheel backwards when it did stall?. With a flywheel puller and air wrench it's a two minute job to get flywheel off, if it was doing any of the above it may have been too advanced just rotate the stator plate with normal rotation of the engine by 3 or 4 degrees, fit new flywheel key ..it's dead easy. If the flywheel key is good (i.e the timing hasn't slipped; the only other way it could slip would be for the stator plate to come loose!) you may need to investigate ignition electrics further. As usual please let us all know the solution when you find it.

Have alook at the trickbits website (google trickbits) he does uprated springs

Its' only a theory and it's not only related to Sherco's , is it that it just wont tick over nice and smoothly, I reckon and it may be daft that the speed of the airflow crates a chill factor as it passes through the carb, when it is as cold as we have been having it blocks the jet or restricts the airway (with ICE, albeit tiny tiny tiny) thus crreating the symtoms. Last time out at the Knut there were several of us in same situation (just an observation also but guys with bikes on trailors and racks more so thanin vans for transport) having experienced this before the trick is to get the motor warm/hot and then stop it and leave it for a while for the heat in the casings to conduct back to the carb, it worked for Sherco ,Beta and Gas Gas, incidentally when I collected my bike new I was told that the revised jet size mod for UK had been done;... (I'm talking practically first batch of 250's into UK)Also for my taste and ability I retarded the timing by c.3 degrees, that transformed bottom end response immidiatly although on map 2 it's a bit flat at top end. keeo us posted on what you find.

Thanks for that; the contour was the one I've been using as a benchmark, I guesse one has to bite the bullet and buy spare battery and sd card (s) (one of our rides is for a week inm mountains of Corsica so finding power source and adaptors etc comes into play. Still the main thing is the camera and at least I know to avoid Interlace stuff. Happy Crimble see in May.

Helmet Cameras; I am planning some exceptional rides next year and would like to record them , with this in mind I have started looking at helmet cams and am as usual with gadgets overwhelmed by the choices and sales pitches. Is ther any one out there who can reccomend something good for an old git to use. Please take into account the whole use experience you have has , i.e batteries ,charging, fixing to helmet, storing, processing,editing data. etc etc. Thanks in anticipation

Santiagosa is good also there are some good trials in France I'm doing 3 days in Jume @Ardeche, Geuret 4 days in July, Aveyron 7 day in August and hopefully there will be a 3 day in Haut vsges in July (weekend after Geuret)

probably what the other guys said but also dont forget that ambient temperature makes a big difference as well cold tyres are stiff like old trials riders

Another benifit of doing that is that the lever is less prone to crash damage

Let us know when you get the answer; I do the same; I think it's to do with getting front back balance right first then working on side to side
