The Yamaha 600 SRX
	Not that I no longer enjoy enduro but I just wanted a fun bike to take me around during week days. An R1 would have been sweet, I could have settled for a VTR 1000 too but my current budget just wouldn't let me. So I looked for something else to have fun with, something that doesn't not make insurance companies or tires resellers smile when they see you walk through their doors. That is when I remembered Patrick, an old buddy of mine who used to race with us. We were all riding sportsbikes, 900 CBR, 750 ZXR or GSXR's and his bike always was the ugly little duck of the bunch. Naturally we always teased him about it and that despite the fact he often managed to pass us in those tight corners. His bike was a Yamaha 600 SRX.  Feel free to share your views on this page or its contents here

	Shopping Resources You find that OEM parts are too expensive? Can't put your hands on that special part? Here are a few good adresses to help you in your quest. Miscellaneous Parts: Mark Apeland offers a wide selection of selected after market parts for your SRX. Very friendly service. Thumper Stuff   Regulator: Electrex USA manufactures quality replacement and OEM electrical parts for the motorcycle industry. The regulator rectifier reference RR8 and NOT RR7 as indicated on the electrex site, works perfectly on the 600 SRX provided that it is grounded. In order to do so just pull a wire between one of the screws that holds the regulator to its aluminium support and the frame. For European customers the RR8 can be bought from BB BikeShop U.K. - Yamaha Regulators for around 65 Euros instead of 110 Euros for OEM   Alternator: Similarly the alternator reference G45 fits the SRX. European customers can also find it at BB Bike Shop U.K. - Yamaha Alternators for around 85 Euros instead of 440 Euors for OEM

	Tips & Tricks Three versions of the SRX were released. The first two ones are only slightly different and were sold in Europe between 1986 and 1990. While the third version is based on the same engine, it is a radically different model with a redesigned frame and body. It was only sold in Japan. For more info on the different models of SRX, check Ander Nilson's site Eliminating the battery Besides allowing you to have lights when the engine is not running, the SRX battery also acts as a buffer that "flattens" the electricity ouput by the regulator. Therefore removing the battery and shortcutin the SRX's electrical system will fry all the bike's lightbulbs. To circumvene the problem, the battery can be replaced by a big condensator, often called a battery eliminator. The following 3 suppliers sell such part. Alternatively a fellow srx rider pointed out that any electrochemical condensator with the following specs: 4700 microfarads / 25 volts would do the trick. Kedo in germany sells a "batterie eliminator" ref:33070 for 22,90 Euros on the page 284 of their catalog. The Bat-Pac is another product. It sells for $50 on ebay or on their site. Finally some Yamaha models like kickstart WR or TT use a battery eliminator. My local dealer had a whole bunch of them from enduro riders who did not care for headlights and sold me a brand new one for 20 Euros. Works perfectly on my SRX. warning:Do not run your SRX with a discharged or dead battery! The regulator will fry itself trying to recharge it. Mounting straight handlebars Some SRX owners have mounted a straight handlebar (drag style) to replace the stock bars. This requires modifying the top triple tree to mount the appopriate clamps. An easier solution maybe to replace the SRX top triple tree with one from a 600 Radian (YX). The Radian and the SRX share the same front end and fork parts should be exchangeable. I haven't tried the mod myself so any feedback would be welcome.   Changing the 5th gear One of my fine fellow compatriot had the good idea of creating an excellent step by step guide including pictures on how to change the 5th gear. well worth a look [go]   Mounting an oil cooler Parallel - Those of you who have taken a close look at the clutch cover or their SRX have probably noticed strange protuberances close to oil filter cover. Those are meant to derivate the lubrification circuit through an oil cooler. The following page shows you how. [go] Serial - An oil cooler can also be mounted "serial" between the engine and the oil tank. You will find exlplanations as to how to do that along with other usefull tips & mods on Modifs SRX-6(french only)   Going electric Kick start is not for everybody and some of us with weaker calves have decided to go electric by adaptating an XT-E engine on our SRXs. Nicolas was kind enough to describe this modification.
