    Any Gold Coast/ South Brisbane Riders

    Thanks for all your help guys. I went to Mt Mee last week and had a ball. I'll check out all the sites/info youve given me. 5th gear back wheel XR600
  2. I have recently moved from Sydney to the Gold Coast. Does anyone have info on enduro riding in th Gold Coast Area (within 100km radius???) Im riding a registered XR600 and am finding it hard to find out where to ride. If anyone is into this type of riding, it'd be great to go riding with you I'm 35 yrs old........not really the Crusty Demon type of rider, but can handle a bike.... Any info would be great

  5. I have recently had some top end power problems with my 98 XR600. Whilst removing the carburettor to check main/pit/clean etc, I have noticed that the inlet manifold has had the restriction taken out (which is good). On closer inspection I have noticed that the inlet manifold has in fact been filed out internaly... so much so in one spot there is only a wafer thin gap between the sealing o-ring and the plastic/bakerlite inlet manifold. This filed out manifold means that there is a 3-4mm overlap when the manifold is bolted to the engine. I think that this may create turbulance in the manifold at higher revs, thus creating my top end power problem What do you think.

    98 XR600R lacking top end power

    Thanks for all your help guys. I'm off to take the carb off and to replace and check and clean carb jets float internals etc. Just one other question also Do these bikes have a small amount of puff through the crankcase breather hose as mine does. Not a lot, however a small amount. Also if I get the kick starter to top dead centre (compression stroke), if I push real real hard, I can push through the compression stroke without the decompression lever. I heard they have a automatic decompressor also??? Can you enlighten me??

    98 XR600R lacking top end power

    The power drops off sharply in the high midrange. It doesnt misfire at all. I havnt yet checked the plug colour, however at my next opportunity I have it planned to plug chop and alter jetting accordingly. I am a novice at this, although am very mechanically minded.
  8. I have recently purchased a 98 model XR600R and it appears to be lacking top end power. I have had a friend who has had a number of these bikes who says that it is running like his de-restricted XR400. In addition I have taken this bike to the local Honda shop here on the Gold Coast, to be told that there could be a myriad of problems causing this lack of power. This bike has an original 5000km on the clock, which is confirmed by the lack of wear on all of the external components. I bought this bike off the original owner who rode it mainly on the road, and changed the oil/filter at 500km intervals. He said he used Fully synthetic oil since new. The checks I have performed have confirmed the following. Exhaust and Header have been removed and inspected to confirm that any factory restrictions have been removed, including rear spark arrestor. Carburettor has been removed to confirm that inlet manifold rubber restriction has been removed. Rocker cover has been removed to confirm valve timing is stock and hasn't jumped. Spark plug has been removed and gap set. Valve clearances have been checked 0.004 inlet and 0.005 exhaust. Aftermarket air cleaner has been cleaned and oiled and airbox has been checked for restriictors (none found) Main jet in carburettor has been checked to find it is a 165 main jet. All of my riding will be vitually at sea level. This problem is s__tting me to tears. I suspect a jetting problem. Can anyone help??
