Beta

My adventures in mechanical imcompetence continue. I want to remove the airbox to check the rubber boot for tears and get easier access to the intake manifold to check that and take a look at the reed block. However, I can't get the airbox off! I've removed the screws in the "subframe" and loosened the boot at the carb, but it steadfastly refuses to shift. I feels like it's still attached somewhere on the right hand side where the mid pipe meets the silencer but there's nothing obvious and I wondered if there's something I'm missing. I anyone could quickly outline the procedure for airbox removal I'd really appreciate it and promise not to ask any more daft questions for…

does anybodyknow where i could get a wiring diagram for a 95 techno online? also how could i wire the fan so it turns on with a switch? i will be gratefull for any help gez

on my mates bike '98 techno ,the water in the expansion tank isn't getting hot at all, but the radiator is hot to the touch ,should it not be like a car if you unscrew it , it pushes hot water out, any ideas, also the bike seems to run on a little bit when you rev up and release cheers guys

Nice to see a Beta on the podium again!! Bravo Cabestany!

Thanks for the help with info on the 2000 model pro and cons. Decided to pass on it because I just don't like USD forks. I have found an '01 250 and wondered if anyone could tell me an characteristics or things to look for on this bike. Help me one more time and I'll quit bothering you. Any tips appreciated because I'm going to buy this one unless there is a problem I don't know about with this model. Thanks for any help, there are just no trials ridrs where I live so there is nobody to ask.

Just a quickie: Does anyone know the standard (factory) jetting for a 2002 Rev-3 270 (pilot/main)? My bike's got a 150 main when I was led to believe that 140 was standard...

Hi all... The weld on the final bracket of my end sinlencer broke yesterday. has anyone else had this. DO you think another weld/repair similar will be OK..or should I make a ring/collar to go all the way around it to support it better??

After reading all related posts on the subject on this site and having exhausted all other possibilities (carb, cooling, fuel etc.) in an attempt to cure my Rev-3's pinging problem (clarkp's posts have been particuarly helpful - thanks man!) I've finally accepted the fact that I need to investigate the timing. The problem is, this is one job that I've never attempted before and once I get the magneto cover off I'm not really sure what to do next. I guess I need to remove the flywheel to get at the stator (do I need any special tools for this?) but once that's done I'm not sure where to look for the adjuster screws etc. If anyone could point me in the direction of a site…

I got the 2001 Beta and am in the process of going through it and one thing I am working on is cleaning the exhaust system. I have the silencer cleaned and ready to repack but my question is about the mid muffler. What is the best way to clean it? I am assuming that it has packing in it also so I am not sure if I can run a solvent through it. I have it off and proped by the shed now letting the oil run out of it. I was thinking of dowsing it in degreaser and blasting it out at the car wash with high pressure hose. What is the best way to go about it?

i want to make my bike more powerful and snappy off the bottom what reeds are best and which ones shall i buy also if i get new reeds will it effect the top end power of my bike

I drowned by Rev 3 in some fairly deep water this past week. I had to flip the bike over and pump the water out of the cylindar. I also did the following: -took apart the carb -cleaned out the airbox. -removed the right side flywheel cover, dried and sprayed with WD40 -changed the gearbox oil three times, running the bike briefly after each oil change. The last change showed no signs of water. Is there anything I did wrong or something I should do and I haven't? thanks

Has anybody had problems with removing the wiring-loom from a Rev-3 (02), and replacing with a (Yamaha style) kill switch. Thanks in advance. Gaff.

Greetings All, I posted a message last December about selecting and buying an '04 Beta Rev3 270. I have put a lot of time on it since, and I thought I would post an update. I still absolutely love the bike and I am certain I made the right choice. If you did not read or remember the previous post, I started out on an '87 Beta (9 years old). Then I bought a '96 Techno (1 year old). I competed on the Techno for 4 years. In 2000 I bought a new GasGas 280 for my 14 year old son (bit of a story there). He rode the High School class at the US nationals and the US Youth Nationals on it. After that season, he lost interest in trials. I then had 2 bikes in the basement. A 5 yea…

If anyone's interested Ron Commo has been working with Moto Tassinari on a Vforce carbon fiber reed block for the Rev3. I managed to talk him out of the last prototype, haven't installed it yet, but Ron Sr. says they'll be in production any day now. pictures here http://www.newenglandtrials.org/reeds.htm Call Ron if you want some. http://www.usbeta.com Dan

My recent proclaimation on another thread that I'd solved the pinging problem with my Rev-3 seems to have been premature. Last weekend it was up to its old pinging tricks, although only under under load and when going uphill at which point the pinging is accompanied by blue smoke from the exhaust. I pulled the plug last night and it's black and wet. Combined with the blue smoke, a sure sign of worn piston/rings right? Well in my (limited) experience a bike with worn rings will reguarly foul plugs but mine starts very easily, idles fine, runs fine (most of the time) and has yet to foul a single plug. And why only when going uphill? The uphill thing might be a red herring…

Trials + Motocross web site has a test of Beta's latest offerings

I just lifted this from the 'Sherco / Bultaco' forum... interesting... Informal count of the numbers of bikes of each brand competing in the SSDT... Beta 65 Sherco 60 Gas Gas 59 Montesa 51 Scorpa 21 Yamaha 6 Aprilla 1 Fantic 1 There were 16 riders who did not state what brand bike they were riding.

My Rev-3 250 was delivered to me with an NGK BP5ES installed. I switched out to the Beta-specified Champion N7YC (couldn't find the N7YCC - Copper Core). What is everyone else running in the 250 / 270 REV-3? Is there a cross-reference to a Bosch part number?

My lads 2002 rev 3 will not rev .People tell me its the electrics,if so. will my electrics fit off my 2003 rev3 .At least i will know which to buy.Also if i do have to make a purchase,where is the best & cheapest place to buy in uk.
