Twosmokerfan:
Sounds like a great idea, as mine is not the fire breather that I want and it uses a shed load of fuel. That said, everyone here I asked seemed to think that 7 litres to do 40 km sounds about right. I am flat out pulling a wheel stand under power in 3rd, so work is definitely needed.
Where are you locate in AUSTRALIA? PM me you phone number.

7 litres to 40klms with DISMAL performance like this?????Sorry guys I'm not sold on this engine just yet....If I'm sacrificing fuel,I want to be making more power!I don't have experience with this engine in particular,nor have I really ridden any as new kx500's but I can't help feeling there's something lacking here....The engine is healthy but I'm no way near intimidated of this engine....I ride the Honda quite hard (although I'm no world class racer) it just seems I've always got enough power to loft the front in any gear,including top...I get off it never asking it for more than it can give me...The only complaint I have with it is I can just about feel every power cycle from the engine and it does vibrate more than the kx....I have a 2000 kx500 that I haven't ridden stashed away maybe I need to get it out and run it and see how that runs????Maybe it is my pipe and the service Honda pipe is also a pile aswell????Im not ready to give up just yet but i reckon my old 89 cr250 was just as fast!!

did you measure your squish?I havent rebuilt my engine but it seems to be really low hours....i stuck a piston and rings in it the other day...thats about all.....I been thinking and thinking about this....I was thinking A)Its getting too much fuel. B)its not getting enough air......C) It just cant burn the mix properly for some reason so i pulled the head off and measured the squish.....Well....ITS 3MM!!!!!!Im going to machine it then report back .....
Twosmokerfan:
I didn't measure the squish, but I did note the piston did only just sit below the top of the barrel.
I might give you a call tomorrow.

ride report.....The CR smokes it so far......but im not done yet....Im working on junking the electrical system as i believe this may be where most of the problem is.....ive run a strobe light on both bikes....the cr is rock solid (the black mark i put on the flywheel is steady and dark in colour) and advances/retards...The kx system however is not correct,It is faint then solid every now and then....after a big blip of the throttle the mark disappears all together and it appears to flash 180 away!(near bdc) Ive tried diffrent CDI units and stators.....same thing... my mate just bought a 98 kx500 and same thing on his.The CR feels so much lighter/willing to pick up the front wheel due to its far superior response/acceleration.The klx/kx hybrid feels like a powerful KDX250....i did a few ripping high gear wheelies on it but still no way near the honda....the honda feels like a motorcross bike and the kawasaki feels like a trail bike.....In short honda ripping bottom end,fat power all the way through to the top where the things pulling like a freight train right through all gears.....kawasaki not too bad bottom end,very very smooth power signing off way too early....not right....still something wrong....I have a decomp pusher valve on the cr,the kx has the victa mower valve which is far superior........i will be putting the auto decomp on the cr right after i sort the kx out.
I have a pretty cool idea for the kawasaki thats going to blow your mind....doing cad work for it this weekend and will be firing up the machine centre next week....stay tuned....its ground breaking :)
