    The triple clamp final answer

    Hmmm this is not good. If the dealers are only inspecting the clamps by eye, then it is likely they will only detect the obvious cracks above a certain size. Even then, how are they examining the clamps? By the unaided eye or using an optical microscope or other NDI methods?? I have seen few cracks in my time (no comments please) and and it is generally only after failure or when the crack has reached a significant size that cracks can be visually observed. It seems logical that the clamp cracks found initially have developed between the date of assembly and the inspection period. What about the cracks that will develop after the initial "inspection"? A small undetected crack in the triple clamp can grow into a large crack under the dynamic loading conditions a bike may experience. Once the crack tip reaches a stress intensity beyond the limits of the material (or KIC) of the material...boom you get unstable crack growth and then failure. If the clamps are not going to be recalled then hopefully KTM are smart enough to use an NDI specialist capable of detecting these flaws. I saw this post and thought to add comment. Cheers. Grum.

    Relay Arm linkage bearing No?

    Kevin - Thanks for those details. Hopefully I'll be able to find a supplier for the linkage bearings or else it is OEM/Pivot Works for me . Cheers. Grum.

    Relay Arm linkage bearing No?

    Thanks Hick. I should have grabbed the bearing number when the linkage was apart. Oh well, more practise at disassmbling my bike..... I was thinking that the moderators could possibly setup a section for parts info on the WRF's. ie: Description/part no. and associated aftermarket supply code. Kind of like the parts fische but a bearing fische for our bikes. Thoughts? I am sure there is more than a few members who have thought to themselves "Now what is that rear wheel bearing number?"

    Relay Arm linkage bearing No?

    G'day T'Talkers, Over the weekend I serviced the suspension on my 99WRF. All bearings are fine except for the two needle bearings within the relay arm. One of which is siezed and the other is knackered. The yamaha part number for the bearing is: 93315-32056-00. Q. Is this OEM code related to the bearing number required for reordering from a bearing supply? OR. Does anyone know the bearing number so that I may re-order through a bearing supply. The OEM bearing prices are steeep . I realise that PIVOT WORKS sell a kit but they must source theirs from a major supplier. Numbers would be great, cheers guys. Grum.
  5. G'day, For all Aussie dirtbikers (and concerned international riders ), the motorcycle riders in Victoria Australia are about to be slugged with a $50 tax on every bike they own. It is a plan by the government to tax a minority group. Help fight this ludicrous tax by signing an online petition. Thanks, Simon.

    What oil in Australia

    Hi Pete, I use shell VSX4 in my 99WRF. It is a fully synthetic oil and at $45/4L is kind of dear. Because it is synthetic, only use it if your bike is properly run in. Sidetrack ran their West Coast to East Coast WRF on VSX4. Everything bar 4th gear was in spec after 10,000 k's. Don't be miserly on oil quality. What is a few buck's when you are protecting the internals of a $10500 dirtbike? Cheers. Grum.

    I need a GPS, please advise

    G'day Ben, I use a GPS on most of my rides. It is the base model (yellow body) ETREX and is probably the cheapest unit on the market. If wanting to know exactly where you are is all that you require, then this model will probably suit your needs. I bought this unit over other brands because of its small size and robust case. It can download AND upload navigational data from your PC. A data cable (search WWW for PFRANC) and a software package such as Oziexplorer compliment the unit nicely. Its software (firmware) is also upgradable. I think they are up to V11.0. I often scan a relevant topo map and upload my ride route onto the topo map at home. You can also plan a ride this way by selecting wapoints and download the points from the map into your GPS. I am impressed with this gadget. Then again...if tech toys are your flavour, GARMIN make other ETREX units (legend, vista) that have advanced mapping functions. Cheers man and I hope this helps. Simon.

    Primary Drive Shaft Oil Seal Leaking

    Hi Nige, I have just responded to the same problem with Jaffie please see this post. Grum.

    Oil seal

    Jaffie, It is an easy fix. The part sells for cheap through Yamaha but if you can get the seal code I'm sure you could order it for half that through a bearing supply. 1. Remove 32mm sprocket nut, sprocket and washer. 2. Remove small metal cover over output shaft. 3. Using a fish hook, needle nose plies etc. dig that sucker out of the case. 4. Remove all grit from seal space within the case. 5. Using a similarly sized socket matched to the OD of the seal, carefully drive the new seal in place. Hope that helps it is a simple job. Regards, Grum.
  11. G'day all TTalkers, Just a quick update on last weekends ride through the sand and bulldust of Sunset Country - Outback Victoria. Myself and a fellow Amtra member drove for 5 long hours to arrive late on Friday night at the Ouyen Pub. There we met 3 other riders and a 4WD backup driver. In total - 2 XR600's, 1xKTM300, 1xDRZ400 and the WRF. Saturday morning we geared up and were ready to ride by 8:00AM. Try as I might, the WRF just would not start up. It would cough, pop and fart and then nothing. Right, a tow down the main street will fix it. Nope - just alot of backfiring. Ripped the seat and tank off the bike and changed the plug. It was fouled!?!? First time ever. Anyhow, new plug and she fired right up after the second kick. A 30km transport section and we were into the sandy desert terrain. I must admit, I was intimidated at first at how the bike drifted at speed along the sandy tracks. However, km after kn my confidence grew. I just gripped with my knees and let the bike choose its own path through the soft stuff. Yamakaze - I nailed a rider as well! My new rear M12 spat out a rock the size of my fist to strike the guy behind me on his XR6. Luckily it hit his leg but left him limping until the next day! Basically - we rode flat out all day for 360km's. Ron, the recovery driver, met us halfway to fuel feed and water the dirtriders. The bike was able to achieve about 180km without hitting reserve which is great economy even in the power hungry sand. NO BK mod, stock jetting and a pipe on a '99WRF. There are numerous salt lakes out in Sunset Country. To ride them is awsome. Both wheels drifting tapped out at in 5th on the salt is like iceskating. Bloody awsome. The second day we rode 180 km's up and around the Murray River. Beautiful territory and wildlife - except for those crazy packs of emus. Those things are damned unpredictable! Picture this. Two sandy tracks either side of 50km STRAIGHT section of trainline. I was on one side and a dude on his DRZ was riding the other. He had about 3 minutes head start on me but I was determined to catch his dust trail. Caught him, passed him and his comment at the end of the rail line was "Man I heard you before I saw you and when you passed you were bloody flying.". Lessons learnt on the 2 day 540km adventure. Bring 2 airfilters. Ride the sand at 80-100kph+. Tyre selection is not critical until it rains. Ride with my tools in a bumbag not in my backpack. Pack extra water and fuel in the space previously occupied by the tools. Stay out of the dust as it is bad on the lungs, eyes and airfilter. Sand is more forgiving and line selection not as critical as bush riding. Cheers everybody and hope you enjoyed reading about my desert experience as much as I enjoyed riding it. Grum..

    Desert Rider Virgin

    FastGregg, GlennT, Dan and Mat, Thanks for the replies guys. Yes I will certainly be on the lookout for some naked chicks in the desert. Prepped the bike over the weekend. Reoiled the airfilter, regreased stearing head bearings and tightened every nut and bolt on the bike. Oil was changed 50k's previous. That was good advice on the rocks, roots and washouts. I will remember your words of wisdom. Evil Simon - C'mon you hold it wide open. Good Simon -Not so fast - watch for those damned hidden rocks. I always ride with a camelbac but will probably take 4L instead of 2. In regards to armour - I purchased myself some Dainese "Ninja Turtle" armour for christmas. It gets bloody hot whilst riding with it on. The safety features such as spine protection, shoulder, elbow, kidney and chest plate make it all worthwhile. My neighbour was riding last year and had a minor getoff at 20-25 kph. As he threw the bike and on impact with the ground he landed on that 1 in 10 million spot on his back. Four hours later he was in ICU complete paraplegic. He now rides a 3 seat, VW powered trike . Anyhow thanks for the info and keep it on the back wheel. Grum.

    Desert Rider Virgin

    G'day All TTalkers, I was hoping that you guys could fill me in with some hints for desert riding and bike setup. I am desert riding virgin and my only experience is on tight single track trails, mud riding etc. I am heading for a 500k desert ride next weekend and am prepping my bike as follows: Metzler Heavy Duty tubes front and rear Michelin M12 rear Metzler MC5 front Filter skins (oiled pantyhose) 15 psi front and rear (?) Obviously spare L+R levers, spare tube, plug, joining link, bike pump, spanners etc. etc. I'm currently running 14:50 gearing but will it be OK to up the CS sprocket to 15 teeth to cope with higher speeds? What gearing do you run for the high speed rides? What about my suspension? Should I increase the compression to stiffen up the forks and shock for the soft sand? Rebound as well? Anything else other than holding it WIDE OPEN? Your thoughts and experience on riding this type of terrain will be appreciated. Cheerfully the desert virgin, Grum.
