    Anyone ride their XS off road?

    Did you get those from me? Check your local hardware store nuts and bolts section for shims. Just bring the shock in with you to test fit the bushing end, and use a caliper to measure the ID or a generic bolt that fits. I honesty don't recall having a bushing issue on my 1978 standard with...

    Anyone ride their XS off road?

    Sheet iron is next weekend but I'm out this year. Wife just had our newest baby yesterday. That said, I have been having fun up till now. Each episode is approximately 30 minutes each, shot by a good friend and my trail guide here in Northern California Sierra Nevadas. Ride to Washington Town...

    Ninja EX500 carbs on an XS650?

    My 1978 standard is running a single fuel valve type petcock, aftermarket type from Mikes. The right side I simply blanked off with flat plate steel and a homemade gasket. Been working great for over a year now.

    Read back aways, I chased that leaky carb issue straight to the "T" myself. What an ordeal!

    Is float level too low? As I recall proper level is slightly ABOVE the seam. Not sure if that's a factor here.

    Ninja EX500 carbs on an XS650?

    Xs650 has significant driveline lash at low speed. That's a fact. Could be dirty/clogged fuel passages or incorrect float height setting. That said, I too get a stumble every once in awhile right off idle but only on the street. Never on trails where I run little to zero throttle for long...

    Sorry I ne'er read what needles and all you've got setup. If it's like his, make it ALL like his!

    The old Amal bores wear because they made the slides out if the same pot metal material. New Amal Premiers have hard anodized aluminum slides that do not wear. For the record. ; )

    I want to say its within the first 15 pages of this thread. I believe try do run better than the bs138 I had. Note that if you have the carb holders for 38s you will need to get ones made fr the bs34. The intake diameters on the cvk are 34mm. I recommend JBM. They are pricey, but very high...

    As I recall needles are around $6 each ad jets similar. Look back in the thread for links to sites for purchase. I bought mine from jets r us and my biggest gripe was shipping was a flat $7. They came in a prepaid envelope with a shipping label cost of just over $3. But they were swift to...

    Also check to make sure both needles engage at the same level. A little air pressure check (mouth over air vent junction while blowing gently) while moving the floats up and down to determine actual needle seat height and proper seal is an easy way to check.

    I use a dab of toothpaste on the end of a q tip. The little brass hole where the needle sets should be free of build up, burrs, discoloration, etc. a little spin action with the paste or simicrome polish will make that surface shine. That allows the rubber needle tip a fresh seat. Also use the...

    Have you checked the condition of the float needles and the dressed the seats?

    Also, these floats are very height sensitive. That said, once they're set they stay. So measure them, set them, forget them.

    Ninja EX500 carbs on an XS650?

    I've got about 1000 miles on my setup now (38/138 GJH on richest clip setting, Uni foams). Runs great. I hold the choke open while starting when cold (on center stand) with no complaints. As soon as it fires let it go and give it a bit of throttle. Settles into nice idle at 1100-1200 after a...

    2015 Yamaha kick-only EFI equipped SR400 in the USA?

    What people aren't factoring is the huge aftermarket potential of the sr platform. It's a simple, basic motorcycle and the old sr has some pretty substantial motor hop ups. It could also go on a diet without much trouble.

    Ninja EX500 carbs on an XS650?

    I may be running a bit rich myself. GJH needles on the bottom (richest) clip setting. Jets at 138/38. I got right around 40mpg on the last tank I measured. That sounds quite a bit lower than most around here. That was some pretty aggressive riding, speeds 65-75mph. Thoughts?
