I originally placed this on the Sherco/Bultaco page but think it has got buried there. I am thinking of getting the electronic ignition system for my 199A 350 Sherpa does anyone know, do they fit straight on ? what effect (if any) to the bottom end power better or worse ? is it easy to time correctly ?

dabber, I have recently had a pair of fork springs made for my bulto 325 & they are really good I got them from, Paul Savage Unit 17 Enterprise Works 28 Hemming Road Washford Ind. Est. Redditch B98 0DH tel 01527-521666 work 01527-893151 evenings/weekends I think he makes all types of spring

sounds like a good idea does anyone know do they fit on without altering anything & how easy is it to time etc any difference to the bottom end power better or worse ? bike is a 350 199A

thank you HondaRS I have not as yet had the chance to try a 4rt but looking through the website many people who have bought are very pleased with them I am sure they will be a very good clubman bike the engine oil I imagine is taken from the gearbox & pumped around is how the previous models were lubricated

it might sound a silly question but then again ? in the 20 yrs since the last 4 stroke hondas were ridden by steve saunders etc, the ones with the disc brakes & monoshock suspension which seemed brilliant at the time how do they actually compare to the new model, honda would surely have used those bikes as a yardstick when developing the 4rt and I would think that ignition & fuel systems have improved since the earlier models were made

excellent pics shame about the weather but looks like he may not have to wash the bike

well done mick still the top man what was he riding this time

any one know who has won the p65 scottish

my own bike is a250 I think it is superb & just right for everything in the events I ride, the motor is very smooth & pulls brilliantly the 270 seems to take more riding than the 250 I think this is why there always seems to be more for sale than there are 250s but then again they maybe sell more new 270s I had a short ride on a 200 (1/2 a lap in a club trial) & thought it as good as the 250 with an even smoother feel to the motor & it went everywhere brilliantly look at the review of the Bete Rev 3 200 on Moto-Merlin website (link on TC home page) but all 3 bikes have the same frame etc so it is only the motor that differs why not blag a brief ride on each at a trial by the way the 200 Gas & Sherco are overbored 125s actual ccs is about 160 so are still nearer a 125 the Beta is 200cc so nearer to 250 the biggest updates came with the 03 year change & not much major has altered since so that is a good year to go for but the earlier years are fine let us know what you find

what & endure all that beautiful weather, outdoor evening meals, excellent coffee & good vino and based at florence surrounded by the umbrian hills beatiful architecture, mediteranian beaches and gorgeus girls dont go lad stay in leeds too many distractions

Thanks Jay I have been to the USA but never Oregon if however I make it to your area it would be great to have a ride on the Hodoka makes me feel somewhat better to know it is not only here where it rains & rains, still at least summer is coming along soon good luck

Jay, have had a peep at the bikes they are real lookers I would think good to ride as well being nice and light we do not have hodoka bikes here in the uk I have only seen one nicely restored example at a classic show it is the variety of bikes of all ages that makes trials so interesting good luck & good riding

it is good that you are rejoining the trials scene you have an excellent bike in the beta to my mind the best may 2nd I think (check the website) man 17 dead easy @ high edge near buxton good event turn fuel tap off after each event to avoid flooding spark plug champion n7ycc keep a spare to hand lots of web based info & john lampkin beta uk has a service schedule on his 1 radiator 50/50 distilled water & a good antifreeze gently lever out the black plastic cover to the left of the steering head screw on cap inside fill to top 2 check window for oil on left below water pump drain plug underneath thro sump plate oil must always cover window 550cc 3 2% wear when chain is clean lay out on a level surface in a straight line compress then pull from one end if overall length increases by more than 2 links in 100 then chain is due for replacement 4 2% or 50/1 silkolene comp 2 pre-mix with (if you can get it super unleaded) or regular unleaded

Went to the big Stafford Show on Sat. there were a number of interesting trialers for sale inc. a tidy looking Armstrong Hiro were they any good he was asking

Sounds good Stu so when is the typhoon season & how long does it last are any trials held in China or are they all in HK what bikes are most popular etc

Stu, Should have included this on my earlier post but it did not happen, when you fit your footrests take care so as not to over tighten the mounting bolts or you will once again compress the brackets I tighten them until the bolt can just about be partially rotated with thumb & finger, ideally the bolt should not rotate in the mounting so as not to cause any wear. If you fit Hebo rests the tube should be free to rotate on the bolt between the brackets this then evens out wear in the footrest. The nylon ring in a nyloc nut stops the nut from undoing but if the nut is removed and replaced a number of times it wears out you then must rerplace the nut. Usually metric nyloc nuts have a blue insert white is used on imperial. Most nyloc nuts used on trials bikes are T- type these are not as deep as normal if you struggle to get them plenty of places supply mail order contact me if you need further info. Nothing wrong with Beta footrests but the Hebo ones are better, I do know what you mean about retaining originality though.

Stu, I have fitted Hebo footrests to my Rev 3 they are a straight replacement and should fit without trouble. Could it be that the pivot bolts have been overtightened on your machine and have squeezed together the mountings, if so you could try this get a 8mm bolt that is much to long and two nuts (plain not nyloc) place one nut between the bracket where the footrest goes and screw the bolt into the nut then add the second nut turn the bolt until it is through both holes and then wind the nuts out until they touch the insides of each bracket now gently tighten and they will expand the bracket but will keep the holes aligned. If you need to buy/beg/borrow a longer bolt one that is threaded all the way down is called a set pin. Hope this makes sense good luck.

Did anyone get a picture of Arthur Brownings Jawa trials bike

Incidentally looking at the Vesty Bultaco I had not before realised just how low down in the frame the swing arm pivot point had been relocated much lower than any other Bulto, I remember reading that this would give far more wheel grip but the underside of the swinging arm ran so close to the chain lower run that a roller was fitted to the nose of the swing arm to push the chain down and away from the swing arm pivot as the suspension compressed. Can only think that it was not quite as good as they hoped because nothing now is made quite like it.

I too liked the Rathmell bike it seemed smaller and more compact than a production model with really neat touches like the kickstart that did not pivot but slid between the fins and out of the way. I remember being amazed and in awe of the riding skills of Vesty on that bike and remember thinking how good if they produce a similar model for sale, in contrast the Schreiber bike appeared to be virtually identical to my own and carried no obvious works touches like Malcoms bike. The presence of works machinery makes the show for me last year we had the Honda to look at and that presumably was used in competition against Vestys Bultaco. Outside and for sale there seemed a vast choice of twinshock and a few monoshock four stroke Hondas plus one or two two stroke models that were new to me.

Thank you rim is Akront on a 350 Bultaco & tyre IRC I have not used this bike for a while but am in the process of preparing it for use (hopefully later this month) I purchased some parts for it from Dave Renham at the Classic Show at Malvern last Saturday some interesting Bults there.

Do not know if this has been on here before but if so I did not see it, Is it any disadvbantage to run a tubeless type rear tyre with a tube in on a conventional rim as tube type rear tyres are not stocked by many dealers.

std Cubs have an oil tank but the Armac is oil in frame like many other 60s bikes BSA, Rickman etc, the Armac frame is purchased as three seperate parts ie main loop, rear subframe & swinging arm & each of these three items is designed to be fitted as a direct replacement part to a std cub frame. Each part would save a little weight but when finished dimensionally the bike would be similar to a std Cub. Everything else engine, forks, rear units wheels etc would be no different to any other Cub good or bad out there. As ever the finished article would only be as good as your skills allowed or funds permitted, and then of course it has to be ridden ?

What a superb piece of engineering but this could never be passed off as p65 but what a machine. British bike trials do have a problem with very competitive modified machines which offer usually less weight & much improved steering etc, this puts the genuine article at a severe disadvantage and I think is reducing entries in these events. But everyone wants their bike to start,run & ride well so I guess that we are stuck with this problem however there is an easy way out if all P65/British bike trials organisers laid out all the sections in a more traditional way the riders of these modified machines would find there advantage reduced (the harder the section the bigger the gain with a trick bike) so that once again real bikes would be able to compete on much more equal terms this could only be good for the sport. It is not a new problem in the 1930s Raymond Mays produced 12 ERA race cars to compete against the German Mercedes & Auto Union racers that were cleaning up at the time these cars are still about, all 13 are accounted for. Yes it is true read the book.

I also thought it was one of the best so far, good varied sections well laid out, do they organanise it themselves or does someone from europe run it. Predominantly young spectators too does russia have trials I wonder, they have had some very good moto-cross riders in the past. Dougies bike seemed to perform better yet it was said to be a std model? there must be days when he wishes he had the 315 2 stroke in the back of the van to blow away those big big steps.
