At last Andy....... Your deleting the post was maybe a subliminal action Text talk was dragging down this site. Andy if a bleathre wi a wee chanter wid that be wan o thon text banters? Wit if a parla amo glesga patter, is a text talk? Yur a wee stoter o a prefect. Ta the noo

Steve Sorry you are late the bike is sold. The bike is running sweet now but is still a 4T (ask Steve D) Carb problems sorted out, amazing what can be done once the jets are in stock The jetting changes to get it running sweet are ?????????? The changes to the carb outlet boot are ?????????? PS: Did you notice that Beta offer a thinner gasket (in their race parts) for the 125cc to help boost torque just as I mentioned a while back to a reader who wanted more bottom end on a 125cc Cheers Billy 2T

Why? Do need the metal that was removed?

I agree with Ron This has to be the BEST Beta yet! Where to I send my cheque to? Ron, better order a boat load as these bikes will be in high demand. Cheers BillyT

Welcome to the board. Where abouts on the island are you? Victoria, Naniomo? Cheers

Are you refering to Phoenix AZ. Or a Pheonix as you have spelled that may be in a different place? If it is Phoenix AZ it is mostly rock and more rock. Other parts of AZ has trees, rocks, mud etc Cheers BillyT

Fire the brake cleaner thru the supplied straw. Direct it at the area suspected. Hardly enough to damage any parts or rubber. Hell, people spray cleaner over disc brakes in huge amounts, not condoning that but the small amounts need to test for carb air leaks is negligble. How water works boggles my mind You want the venturi effect to pull any liquid into the stream water will only do that if it is dripping in as it is heavy. Any flammble liqiud will cuase a sudden lean condition indicating a leak. Water will tend to settle cleaner will stay supended in the air being drawn into the carb. The only way water could possible work if it was in a VERY fine mist and stayed atomized. VERY small amounts in a controlled direction are required. Lets say there is a leak, the cleaner will burn up the water will cuase problems of its own exabirating the intial problem Cheers BillyT

WD40 You are supposed to be using contact cleaner or brake cleaner. Not saying that an air leak is your probelm, BUT if you are testing in that manner at least use the correct liquid! Cheers BillyT

What is "Currancy" are you buying currants or rasins? L149 ??? Is that Italian Lire? or GBP sterling? Oh I get it it is Currency! Stupid me! Duh, time to go back to bed

Hi Leggins My wife is from Winnipeg so I get to go back there to visit (unfourtunatly). The "Take Five" club has not exsisted for over ten years now. They got into a big fight after the Rennie world round and all went their own way. No trials what so ever there now! Gary, Francois etc are all doing other things now. Take care and let us know how you get on with the battery pack! Cheers BillyT

Peppey la pew Frenchy the scarf Your bum chum Steve's squezze I giv eup!

Mon ami Steve Arret avec fromage aux repetrois. Sorry I forgot you were well travelled in the trials circles. What about aaaaa Rockypoint, Devils den, city park, saltilo mountain range, rennie, waiprous, fallen timber. Franciose wife BillyT

copemech Looking at your avater/picture it looks like you like to have your bum in the air. Good job Steve does not know were Munster is or else he would be all over that sweet Texas puntang Copemech riding in Munster (Camelback) in September 106F on a Beta with 106 octane and the bike would go lean and vapour lock. Nothing would cure this except me installing a switch on the bars to turn on the fan at will. Installing a small battery pack let me run the fan whilst the bike was turned off. The bike would not start after sitting for ten minutes or so unless the fan was drawing the temps down. Glad you spoke up about the hot riding in Texas and how it can play havoc with some bikes. Thanks BillyT

Rev3 True statement! BUT, I am talking about keeping some air flow across the head here, not lowering the temps dramatically! The air is being sucked or blown across the rad (dependant upon bike type) if the bikes is HOT due to it being a VERY warm day then the ambient air from the fan blowing/travelling across the cylinder is also going to be very warm. If the bike is stopped then the water pump is not turning, so the coolant will still be hot, due to a lack of circulation, the only real cooling affect would be on the air across the head! At best, ambient air with not much of a delta T (pre fan air Vs after fan air). Hardly enough to drop the temparatures to loose power. Cheers BillyT

Dear Ron How does a small (very small) battery pack that is removable add much weight. The fan does not draw that much current and so it can be powered by a Duracell battery. PS Do you remember Globe Arizona when you poured a jug of cold water on an extremly warm Beta cylinder head and then wonder why the head cracked??? Talk about Duh Perhaps we should install a water cooler on our bikes so (oh and lets add ice to the water) so that when they heat up we can dump the lot on the bike. Who care if it cracks stuff due to the thermal shock. And why do you continuly shout at people on your web site (all capitials) We can keep this up all day/night if you would like?

Feetup fun That is all the more reason to have a switch for the fan. Because the bike is sitting idling does not mean that the fan is on!!!! In fact if it is sitting there idling and no movement or air passing thru the bike and no fan turning the bike will be getting hot! You may be fortunate that you can let the bike sit and idle whilst you walk a section, the terrain and space may allow you to do that. BUT what about areas that are very steep or mountains and lots of wooded area. They can not let the bike sit upright as the paths are too narrow. There may be cases were there are a large party of riders and you have to pull your bike off to the side to let others thru as you are still walking the section and watching others ride it as you are trying to watch their line. Some bike do not have their kickstand attached and have to lean the bike up against a tree for support. Some loops are realy long and you need to turn of the bike to save fuel in between sections. Some of us older riders have their idle turned down so low that the bike does not idle too well by it self. All of the above forces you to turn the bike off and park it. If you do, you need a switch and a battery pack.

Steve My bum is not as pasty as your bum. Remember that night in section 5 when we compared a Scottish bum to a Canadian bum Leggins To add the battery pack one needs to wire the switch in parrallel with the temp sensor and add a diode to stop the voltage from going back into the bikes electrical system. The switch can be activated when going slow and the bike will power the fan, when stopped the switch plus battery pack will turn the fan. Works like a charm! I have installed the same set up on other brands of bikes. Cheers BillyT

BetaRev3 I hope that is a class teaching how to set up the Mikuni carb to the specs. Strange how it works 100% of the time when it is adjusted in my presence? Just being a little cheeky here. Cheers BillyT

Leggins I do not think the bike was ORIGINALLY flooded but rather the jetting is way to lean for the hot enviornment that day. When a Beta heats up after a lot of hard riding or very hot weather the bike can go in to a lean condition and vapour lock. When the frame is to hot too touch and will not start after a hot day I can assure you that flooding was not the ORIGINAL problem. You the created the flooding scenaro by not fully understanding what the symptom was. The early Montesa's (1994's) with the big aluminium frame had the same problem in the really hot climates. You did not put the choke on before the symptom arose, you may have turned the throttle to much when it did not start, but that was not the original reason why it would not start to begin with. You exasparated the problem by continualy kicking it over, hence why the flooding and drying out of the plug helped you. When it is warm outside the bike can run rich. Needs less fuel and more air The opposite is true when it is cold it needs more fuel and less air, hence using a choke. BUT when it is REALLY HOT the air expands and the gas gets warm (aluminium frame good conductor of heat Beta, Montesa) forcing the bike to go lean. The solution I have found after riding in 100F temparatures is to go a tad rich on the pilot jet etc. All sorts of things go funky when it is really hot. It is the pilot jet that really helps during the starting procedure (in combination with the idle circut). General foke lore states that you need to be rich on the jetting in winter and lean in the summer. True in general terms. BUT that folk lore does not take into consideration that trials bikes sit stationary or hardly moving. You yourself stated that the fan was coming on. You may be in the woods or an area where air flow is non existent. Keep in mind that the temparature of the bike will climb when it is turned off, and will do so for many minutes raising the temps thru the roof. There is VERY good reason that trials bikes have fans on them on and motocrossers do not AIR MOVEMENT THRU THE RAD. The old turbo units on cars used to fry due to drivers switching off the car after a spirited run and the turbo unit would cook. The temps of the turbo after turning off went nuts as there was no flow of air across them. Ever walked away from car after turning it off and the cars fans is just kicking in? Mmmm. You come back to the bike (short period of time) it will not start, one kicks and kicks putting more and more gas into the system than needed, you pull the plug out and it is full of gas/petrol DUH I wonder why? You let the bike sit for while (the bike is actualy coolling off after initialy climbing in temperature) and drying out the plug. I would bet that when initialy it did not start and you did not kick it, and let it sit for a period of time to cool off it would have fired back up again no sweat. The length of time needed to to cool down would depend upon ambient temps, humidty, altitude, air movement around the bike etc. In really hot closed in enviornment that could be a VERY long time. What is really needed is for a fan to have a handle bar mounted switch to turn the fan on and off. Of course the factory thermostat would still kick in around 185F as they do. One would turn it on as you leave the bike stationary to walk a section keeping some air moving across the rad. Or even when your are idleling through a 1st gear section very slowly. I mounted such a switch on my Beta along with a battery pack to power the fan when the engine was not on when I lived in Texas along with riching up the pilot jet and BINGO no more heat problems. This is the voice and expierence with hot Beta's and good carb knowldge in hot (100F) enviornments. Cheers BillyT

Guys! & Beta riders. Try this when checking any potential spark plug shorting or jumping, do it late at night in a VERY dark area. You would be amazed at the shorts that appear even in a good running bike. Start the bike get close and watch for little glows of light that are jumping to the frame etc Cheers BillyT

Where the hell do you get 35BHP from? A Beta 250 stock runs around 20>21 BHP. BillyT

Are you sure it is a Mikuni carb and not something else that some one has switched out? The jets have to be taken out to read the numbers. As for the colour of the petrol I pressume that you are in the UK since you are calling it petrol and not gas? The colour may be fine if the petrol is always that colour. The oil should not be seperating if you are using a good quality pre mix oil. When I say a 1/16 movement I am stating that one should not be able to move the tang more than a 1/16 when lifting and dropping it. You are tying your self in knots here for no reason. Tell us the sizes of jets you have in the carb first and we can help. Keep in mind that the air fuel ratio gets leaner when the bike climbs in rpm's so it can pop a plug if the jets are to lean. Because a plug is black and sooty it does not mean that the bike is too rich. The bike can be running rich at the bottom rpm's placing excess oil on the plug but at higher rpm's in may be way to lean causing the insulation to go. You pull out the plug look at it and beacuse there is oil on it one assumes that it was fouled but in actual fact the oil from the rich condtion has nothing to do with the lean at the higher rpm's, very missleading to a novice weekend mechanic. BillyT

Movingtarget You are not fouling the plugs but Poping them. Basically the plug is getting to hot breaking down its insulation causing it to lose spark power. Nothing to do with oil ratios or filter. The bike is too lean in the carburation. What pilot and main jet are you running? Have you set up the carb per my specs? As you may be going in to a lean condition due to low fuel levels at higher RPM's..... Trust me on this as I have seen it many times that people do not understand the difference between a "fouled plug" and a "Popped plug". Fouled is due to rich carburation or too more filter oil. A popped plug is mainly due to the carb jets beeing to lean or fuel levels dropping at higher RPM's or even to much oil in the gas which can believe it or not cause a lean condition. Let me know how you get on. BillyT
