    Srx clutching question

    Lester, got your message. You have a 35/118 spring in there now with that aluminum spring shim, it raises not only the engagement speed but your shift rpm as well. If you like the 4000 rpm engagement speed the answer to your problem is to replace the yellow/silver/yellow spring with a...

    2002 yamaha sx viper 700 burble

    ya..wow, if you used half a tank of oil in 130 miles, your full on rich! which makes the sled run leaner on air/fuel ratio. I would definitly look into the pump replacement if your sure the cable is adjusted correctly and the cable is fit back into sleeve. At least theres less mosquitos...

    Headlight issue.

    i would simply unplug both of the relays, take them in the house and set them on the heat source(register) of your house over night, alot of times the relays get moisture in them and freeze up. the heat will dry them out and they work again, easy enough to try first. I seen your up in canada and...

    check how much oil it uses on a ride. mark the bottle with a sharpie marker and recored how many miles you go. then using a ratio rite cup or other unit of measure record how much oil you put back in to bring up to sharpie mark on bottle. When the pumps go bad they do go full rich but I have...

    Srx clutching question

    the over rev is likely the high secondary spring tension from the sec. clutch. just add some weight to the tips. if your worried about buying rivets just put a small dab of mig weld on the steel rivet end and grind the weld to all 3 weights the same. add about .75 to 1 gram on the tip rivet.

    Srx clutching question

    you will find that 98-99 srx make peak hp 137hp at 8350 rpm, not 8500rpm. 2000-02 srx make peak 140hp at 8500rpm. Going to 8700rpm and you begin retarding the timing from cdi box, so no, 8700 is not good. You want the initial hit to be 8100rpm(peak torq.) out of the gate and climb to 8500rpm.

    03 Viper clutching

    adjust them, they cant be operating correctly, thats the exact rpm it will only pull if the valves dont work. usually they are pulled thru the ends from not being removed and cleaned.

    first thing to do is get the manifold off and weld it top and bottom or your going to burn the engine down, it will be cracked both top and bottom!

    Srx clutching question

    what helix are you using with that? you want 8500, no more. if you add a washer to the tip of each rivet it would bring the rpm down. If your helix is low finish thats why its over revving on top, thats why i asked.

    wire harness chaff repair

    always lots of questions on electrical glitches and strange things on the pro action chassis sleds. The most common issue that arises is the wire harness chaffs and rubs thru the wire insulation. This allows the wires arc to the sleds chassis, shorting out and cross powering circuits, some of...

    check out this crankseal!

    worst crank seal I have ever seen. This came out of a 83 vmax540 that came into shop for running problems. I pissed with cleaning carbs, syncing them,etc. and it would not run nice and clean. Looked at the dipstick and it was empty on the gear case. Filled up with some oil and then the sled ran...

    track dyno results for oem yamaha weights

    As you can see on the dyno graph there are certain weights which outperform other weights, even against the opinion of others who claim the opposite. A 8bu-10 weight is only marginally better then the stock 8dn20, and the 8dn 20 actually will out accelaerate it on the way up to peak then the...

    My 15yr old daughter put the smackdown on a nice 10 point today for youth gun season. We had a awesome day seeing 10 deer, with 5 of them being as close as 5 yards away from our tree stand. It was cold and raining but we stayed in the tree and she scored in the afternoon on this 10 point, she...

    srx owners,prevent break downs and engine damage

    As the srx600 and 700 sleds grow older so does the antifreeze which is often NEVER changed during the sleds life. The sleds becoming older also increase the chances for the o-rings on the heads to become fuzzy/white with corrosion build up.The antifreeze does not have the corrosion resistance it...
