I replaced the gearbox oil in my 97 techno as it was starting to look a bit dark, with Silkolene light gearbox oil (which is virtually transparent), started the bike to let it warm up and noticed that after a couple of minutes running, the oil through the window had gone milky. I left it for a few hours, after doing a bit of phoning round for advice, and went back again and the oil is now clear again. Would i be right in assuming everything's fine?

Are technos susceptible to corrosion of the water pump housing by stuff in the coolent? I've heard this is a problem on the Rev 3s because of the magnesium casings? My techno is a 97 model if that makes a difference

I realise that this has been done before, its just that having read the other posts about their Techno's about this, some people mention using spacers. Where would you put them as the exhaust is mounted to the inside of the subframe, so any spacers would move the exhaust towards the wheel? Other than bending back (exhaust or subframe) I guess there's not much else that can be done? Cheers Loomesy

I was thinking of having a fiddle with the suspension settings on my 97 Techno, but I dont know what the adjusters do on the shock or forks. Theres a red spinny knob on one fork leg (not sure if theres adjustment on the other, but if there is i think its an allen key). on the shock theres preload (I know that one) and a blue knob clicky knob. (Sorry about getting all technical on you) What do these do? Are there any other adjustments that I've not noticed? What would be a rough setting for a 75kg bloke? Many thanks

They are both weak, as in stoppies are impossible even pointing downhill, and the lever is spongy. There is no loss of pressure. NOt tried the lever pumping technique, but i think a bleed is in order. It's funny I've jsut bled the rear brake expecting the worst after reading the threads on here, but it couldn't have been easier, the old fluid practically fell out as I topped up the reservior level, and now I have strong enough brakes to lock the rear easily. Win some and lose some I suppose

Ahhh ooops, wont be undoing them any time soon (I hope anyway). I've not swung on them....hmmm we'll see. Thanks for the replies. One other quick one. The front brake is quite spongy and not that powerful. Is this normal for a 97 Techno? I would rather live with it as it is than bleed the brake to find no improvement! Cheers

I have noticed that when I put the brakes on on my 97 Techno, the brake discs are not fixed solidly to the wheel hubs. There is a slight amount of movement as if the holes of the discs have 'ovalised' over the years. As a result, the brakes are not as sharp as I would like and make a noise/judder slightly. Is this normal/do i just tighten up the disc bolts/do I need to replace the discs? Thanks for the help. Loomesy

I'm new to this trials game, and was wondering are all fairly modern trials bikes pretty much the same or are there some characteristic differences between the manufacturers? So for example is there a Honda of the trials bike world which 'fits like a glove', is very usable, has excellent build quality but is possibly a bit boring, or a BMW which is quirky, excellent engineering but a bit rough round the edges so to speak. I'm pretty good at telling different road bikes apart but to my eyes, trials bikes are pretty identical....Enlighten me Cheers

Oh right, cool thanks for that. Especially the FAQ bit I'd imagine that this may explain why it doesnt feel as perky as a 260cc trials bike should. Compared to my mates 96 Techno, which I realise is a lot newer, water cooled, and more powerful, but still...my tr35 seems positively comatose by comparison. Ive found it bogs down a lot, so presumably its running far too rich, coupled with the fact that it running on 50:1 rather than 70:1 which is probably not helping things either...so much for 'running like a dream' Also whilst I'm here is there any reason why there is foamy, spongy stuff in the front brake reservior, my thought is that it prevents air getting into the hose if the bike goes upside down or something. Id imaging if you fill the reservoir to the top, there wouldnt be any need for that??? Apart from changing the fluid is there anything I can do to improve front brake performance? Ive got a braided hose on it bit its still shockingly bad, though Ive heard early disc brakes on trials bikes were pretty awful. By the way on the Beta FAQ it says engine oil (which presumably means gearbox oil rather than 2 stroke): 800 cc. Is that right?? Sorry about bringing up an old thread but thanks again for your help, Im learning stuff all the time. Its much appreciated!! Loomesy

COOOOOOL Cheers for that, running like a dream now..I think

Hello, I have a Beta tr35 with the dellorto carb, which I have recently stripped and cleaned, only to forget in the process, the number of turns out for the adjustment screws. So now I have a bike that idles too high and will rev its head off, which is mildy inconvenient, noisy and a bit scary. I realise the big one sticking out the side of the carb is idle speed adjustment, but not sure about the other one, and how they relate to each other, so would appreciate any possible advice regarding these. Also, whilst I'm here and all that, the bike has upside down forks, does anyone know the fork oil capacity. I know the tr34 which had normal way up forks has 200cc oil per leg, but would the tr35's legs have the same capacity Thanks for any help Loomesy

Hello there Ive got a Beta TR35 260 and have had a few problems of an electrical nature, it but i think generally sorted (Fingers, toes, legs,arms and anything else crossed). The only thing is it doesnt really seem that powerful, especially at lower revs where it bogs down slightly on steep uphills, though it seems to get into its stride more once it's at higher revs. Its also quite vibey and not that high revving (tho i suppose its on par in those respects to a Fantic 200, which is the only other trials bike I have experience of)... ...so I was wondering if anyone else has any experience of these TR's and could tell me if mines typical...or still broken Cheers

Hi Nick Mine also has that number on it and was sold as a 260cc, hadn't considered decilitres though... Although I don't know the answer, it seems unlikely to have the capacity measured to 1/10000 of a decilitre. All the road bikes I've owned have the capacity corect to 1cc How has progress been on yours? Ive sent my coil and stator to Spain to be fixed, hopefully thatll fix it...if it doesnt, I'm all out of ideas

Hello I was wondering if anyone knows the thread size and pitch of the flywheel for a beta tr35 to remove it, as i need to get to the stator. Thanks for your help

Hello again From what ive been reading, these TR and any other trials bikes with USD forks suffer from knackered fork seals a lot (not surprising really)...im thinking of taking off the plastic fork guards which dont really guard the forks, they just look pretty and replace them with some ally guards. Ahh ok...ill give the airbox bypass trick a go...cheers, not thought of that. Does your bike have a guard at the back to prevent mud/water/trees etc getting into the airbox, seems like there should be one. I might put a sock over it to see if that helps a bit. I took everything out of the carb (a dellorto phbh26 if that means anything to you) that i could apart from the floats, now all the jets are squeaky clean...what the bloke was running the bikes on I dont know...smelt like paint thinners...but then as someone suggested, domestos and toilet duck may well be likely. Nah to be honest i dont think itd change much, wouldnt get a discount, i shouldve been less impatient and checked the bike more thoroughly there and then....plus its given me the chance to tinker which ive not done in a while and i plan on passing the bike on as a family heirloom...if the b%st
