I was thinking he same thing ! I think this nice gentlemanshould not call gas-gas brand trash. They have a new factory. with ktm-s help they will be around long time i hope. TimDH should just go and buy a 3 wheeled tricycle. one with handle bar grips that have baby doll heads on the ends of the grips-- custom !! He did say in his 1st post that $$$ was no issue after all ---

My advice to you is to not have such a smart mouth when a member is joking & suggesting to learn how to repair a simple brake issue--

these 2 upper hose fittings are vents. as fuel in bowl is used these admit air into the carb. if the ends of these 2 hoses are under the bike- if you cross deep H2O and give a big handfull of throttle these hoses can pull H2O into the carbs throttle slide area, go into the engine. this fact also applies to fine trail dust also. The filters on ends of hoses are to keep some of the dust out if you are riding in a total cloud of dust, and they will help keep H2O out if you use a pressure washer on bike.

Carbs are o.k. by me. Its a good idea to use a slintered bronze inline fuel filter between petcock & carb inlet. Also, the 2 upper vent hoses on carbs are just that. Vent hoses. Its a good idea to not have these 2 upper hoses hanging below the engine. Yes, when you tip over they will spill gasoline. but its better to have these hoses above carb. End of hoses turned downwards. 2 small fuel filters used for large gasoline r-c race cars on ends of these 2 vent hoses helps greatly.

I ran 927 in a 5th scale HPI 5 b ss. approx 2 tanks of fuel. had to remove the expansion chamber and hot tank it 2 times to rempve the nasty build up in it. 30.5 cc long rod 4 bolt - 18-1 compression ratio. running the buggy wfo in sand dunes. nice smell though-- lol.

If it has wheels or a skirt, There will be troubles. Its best to learn to work on your own motorcycle. brakes are very easy to maintain & repair. just saying----

Thats a pisser hoseclamp !! Your forks could be bent also. Try this-- Trials super store. Inland north west trials. There are many other smaller trials shops all over north america and canada. search them out - forget google, its junk. use start page instead to search.

I have a showroom condition 1992 Wr 200 Yamaha. These were only imported to usa for one year.. 95 octane engine, has a counterbalance in engine !! powder coated frame- sprung & valved for my height- the list goes on & on. The bike came with a Mikuni TM 30mm ss power jet carb. Rare indeed. The slides coating was worn in several areas. Not able to find an oem slide. So- surfed E-Bay. Found a lawn mower dealer back east in usa. He had this China copy. $50.00 usd. Bought it. parcel arrived. The carb body castings were top shelf quality. The supplied fuel & vent hoses were not so good. The slide was PERFECT !! measured it. The slides cut away was same as factory ! I am one lucky dog ! This bike is worth 3-to 3.5 k.in usa. I only used the slide, installed it on the oem carb. This is one sweet mount for putt & explore mode riding. Yamaha should sell them agan. This 200 will walk the dog on a kdx 200-220. And hang dead even with a 2021 beta 200 in a drag race. bit of trivia-- yamaha invented the power valve. this wr was a first.

I am 62-- going on 18 !!! Birthday? I was a spring baby. I saved all my old dirt bike gear, All the chips on the bell moto 4 helmet have a story to tell. same with the dents on the pairs of hi point pro gp -- also known as mad max boots. stainless steel part dents- and the dents on my lower legs shins. -- The trials gear looks pretty darned good.-- mostly just sudden gusts of gravity on gnarly switch back trails. or from what i call floundering out in the over grown off the map trails-.

same plastic on my 20 scorpa. my time is coming too. Find a dirt bike shop show them the carb replace the screw with a metal one, unshure where you are in canada-- if you have time to look on the www, go here www.pjmotorsports.com they are in oregon. bought from them many times over the years.

There are 2 types of fuel filters that I know about. The screened type. The sintered bronze type- sintered could be spelled incorrectly. I prefer the sintered bronze type, It can filter smaller junk out better. in my humble opinion--

yea and gasoline that has doubled in price, plus a shopping cart full of real food thats 200 bucks + -- even finding real food is getting harder each time i shop @ 5am to avoid people . there is my rant & whine-- lol.

Wow. thats odd indeed. i see no hits from rocks on the knuckle, my uneducated guess ? bad metal. or-perhaps the bolts were over tightened ?

might as well give it a try !! For Motocross & Enduro bikes I wonder about having a button some where near the handlebar grip that would allow a rider to shift gears. Thats what formula 1 race cars have, on the steering wheel.

here is a good site about the weights & viscosity indexes of assorted brands of suspension fluids. www.peterverdone.com.. myself, in forks its motorex. in showa shocks, its Silkoline Pro RSF 2.5 wt. I change these fluids often.

that plug color - if that color was at lower rpms, its too lean. pull the carb, remove the pilot jet and blow it out - do not run wire tru it to clean it. I have no background about your bike.- so- this is a wild guess from me. Trials bikes are most times are running low rpms. bigger hand fulls of throttle every now and then. The muffler- the bigger part of it close to the header connector could have been loaded up with wet black exhaust goop. as lean as that plug looked, if you were hill climbing or just running the bike hard, the smoke perhaps is the mentioned exhaust goop burning off. -- this happend to me on low hour 2020 scorpa factory 300. I cleaned carb- air filter- checked plug color on the ally behind house- paper bag color,-- took it for its 1st trail ride - rode 1st- usually 2nd on ocassion. for approx 3 hours- taking breaks - cutting trail with saw & loppers.- came back to truck- ate food- gassed bike up- hit the good stuff- at least 45 degree hill climb on a old trials bike hill climb. it was epic ! about 2,800 feet constant- no break- the scorpa was smoking badly - real badly- i have tempeture stickers on raditor & engine jug. 159 degrees. perfect--- I simply cooked all the wet goop out of the lower exhaust area-- the packing was brand new- cleaned -replaced before the ride-- That bike sucks the gas compaired to the beta techno 250. the scorpa hit reserve about 1/2 mile from the truck on the way back-- i was not reving the bike either-- about 1/4 throttle in 2nd & 3rd. on the hill climb.-- It does not smoke any more after its 1st good pull for about 3/4 hour.--- i bet your bike is the same way- needs the same treatment that my bike needed. pardon my spelling--- db. my spelling-- god o mighty-- lol,

I always have goggles and use a quick strap device. I can take them on and off with a flick of my left hand while in motion. This is of paramount importance for me.

me agan-- There is one type of Alcohol that absorbs H2O, isopropyl alcohol. and not seperate. in america, there is a brand used in cars for water in gasoline, its called heet. there is a yellow colored bottle- never use this. only use heet in the red bottle. its 100% isopropyl alcohol. pardon the spelling mistakes.

Ethanol all form of achalol -pardon spelling are hydroscopic. this means it absorbs moisture. it absorbs moisture right out of the air. In america, fuels move tru pipe lines all over the country. the same pipe lines transport gasoline, jet fuel, deseil crude oil and other fuels & chemicals. this is done by having a liquid buffer that seperates these assorted fuels. alchaol can not be transported tru these lines, rusts the pipes, dissolves the buffer that seperates the fuels. it has to be transported by truck. and- the ethanol is made from plants- this is a crock of **** because - well just look at the price of food. - more money every time i go to the store-- meats - beef prices have skyrocketed here because of the weather- no rain, extreme heat. the food should not be used to make this ethanol. period. -- oh-- break fluid dot 3-4 - 5.1 is hydroscopic also. it absorbs H2O right tru the rubber brake lines.- seals. - off topic here-- loggers shoot every porky pine they see at logging sites-- why ? because the like the smell &taste of brake fluid. at night they chew holes in brake lines. Brakes are a good thing to have on steep mountian roads !! as for ethanol wrecking seals-- it depends what type of seals-- buna rubber- viton- there are many many types made. hope you all can read this with my lousy spelling-----

Here in the states, there was talk about having E15. The companies that build cars said if you run this stuff your new car warranty is null & void. This speaks volumes about ethanol.

Here in usa, a person can go to a marina and buy petrol- gasoline that is non ethanol. It could be the same in your folks part of the world ?

In wet weather try this idea. Bolt a wide copper strap to bare metal on bike frame, long enough for it to drag on the ground as you ride it. Its volts that jolts - Its current that kills--- . I was riding my techno - rode underneath High voltage power lines - 4" cables on the towers-- big time power lines that come from grand coulee dam and feed seattle, wa. As i went under this tower, my gloved hand with 2 fingers on clutch lever had a shock. Frightful. Volts that jolt, current that kills-- This is why living things can take a direct lightning hit and live. Millions of volts, but very little current. Same with sliding your feet across carpeted floor and grabbing a door knob. approx 40k volts but very little current.

I think gasoline has been spendy in europe for long time. Its become spendy in usa this year. All carbys - aftermarket - holly-barry grant- ect- have a fuel enrichment divice. its called a power valve. its located between the main jets. At light throttle settings, engines have high vacume.-- as the load on an engine increases, it loses vacume.example- a 6.5 hg power valve- when engine vacume drops below 6.5 hg, the valve opens. A standard flow power valve is main jets X 8. this quenches -cools combustion chamber temp -slows down spark knock and adds engine horse power and drains the gas tank & money quickly. The Weber on my little truck does not have a power valve. This helps to go long time between gas fill ups. There are carbs for motorcycles that do not have pilot & main jets. The fuel is metered tru the needle valve. Its called a Lectron carb. A advanced version of a lectron is called a Smart carb.-- VERY spendy. I put a standard 38 mm Lectron on a rm 144 suzuki. - It would run like a scalded dog on top end, but it had a rich hitch off idle i could never stop. several types of needle valves slides later i put it back in its proper place- the cardboard box it came in. Bought a Kehin 36mm pwk air striker short body carb with jd jetting kit- Thunder products quad flow torque wing. -- runs really good. Thunder products torque wings only go down to fit 36 mm carbs. I would like to have one of these for 28mm Kehin pwk series carbs. Put one on my Scorpa 300 !! They make a HUGE increase in power right off idle -- with proper re tuning-- torque wings cause a engine to become richer off idle - into lower midrange. As usual. paedon my spelling mistakes-- I have a decent command of english--- but my spelling----- lol.

I am in usa. I have a 97 techno. I have found a seller in u.k. found some hard to get parts there. Its called Trials & Tribulations. He is a good seller that ships quickly royal mail to western usa in 10 days !

Oregon? what part ? 2nd house i flipped was south of Pendleton. Pilot Rock, Or. totally safe there. Never took the keys out of the cars-trucks- never locked the house-basement- gone for days dirt biking- kayaking, Told the neibors, you guys are welcome to the tool boxes in basement- but clean the wrenches up before you put them back in the roll aways, and- The 1/2 inch torque werench is NOT a breaker bar !! leave in the box. !! Pilot Rock is a sawmill town-- good jobs there too- but i moved to central wa. Ephrata, wa. big house- 5 br, jacuzzi, showers soaking tubs--- bout 3 k sq ft-- life is good-- lol. kinda miss oregon though-- dave.
