High idle.

Post by gurunik » Sun Jun 07, 2020 2:44 am

A month into TRX land, and have found my 1995 one is idling at 2000rpm when warm, fine at 1000rpm or so when cold. idle adjustment screw backed off all the way. Suspect vacum leak perhaps, carb to head rubbers on the way anyway. 36000km on it. perished rubber bits, or in the guts of the carbs? Goes fine in all other respects....

Try to do one thing at a time, replace the carb rubbers and run it. The carb boots can be replaced easily with just the choke cable and the TPS plug removed, there is no real need to disconnect anything else...initially :D

The carbs may need the emulsion tubes and the main metering needle replaced, but first run the bike and see what the change has made.

You will find if your bike (1995) is still fitted with the original style carb rubbers, the new carb rubbers are different and the original clamps are difficult to access and the top clamp is a pain to tighten.

The original rubbers are in some cases 25plus years old and crack this will cause the high idle, slow to start and high rpm misfire.

Replace them with genuine Yamaha rubbers as the aftermarket rubbers are hit and miss with the quality, the original are $25 each from Yamaha. The aftermarket ones advertised on the Bay are similar price including postage..

The 1995 bikes are a little different in many aspects and have some parts that are no longer available in their original form, Yamaha has updated them to a subsequent evolution which can cause problems, these boots are one such issue.

Original boots V the new evolution, note the 3LD, 3LD01.

Original boots with the clamps on the top side facing slightly towards the back of the bike and are easy to remove etc (left side is reversed).

The replacement boots with one clamp easily accessed on the bottom with the other top clamp now facing up is fairly hard to get to as the frame gets in the road!

The new nickel plated (90450-57016), the old passivated black clamp (90450-57034).

The only real visible difference is the screw, which is now an Allen Key style, so the use of a ball end key will make it easier to fit.

If it's not made in China, it's a fake!

Thanks Rod.S, very quick reply! I''m just getting to know her now, and very interested in the differences that the 1995 JDM has vs the aussie models. Still goes like a shower of shit though! After 20 years of honda 4s, this is the bees knees... Love your work.

And can you give a heads up on a good parts supplier ( in Australia hopefully) for this model specific stuff? I'm new to Yammies..

Well..... had the later rubbers on as well, 01 suffix. put them on, not to bad to do, and now idles like a dream, even when fan kicks in.
I am suspecting this has had some work done, has bare heads, not painted like rest of motor. history is vague, imported in 2005. But geez we are bonding..... ;)

Well Yamaha has all the bits you will need and some at quite reasonable prices. I also use Wemoto and the Bay. For second hand parts try the forum or Facebook :roll:

Still trying to find a seal kit for jdm bremos in Australia. Fricking hard work. Any ideas?
