Here is that Aux fuel bottle, and it's only 300ml's. I remember having to refill it a few time's when i was tuning my FZR https://www.ebay.com.au/itm/Auxilia...778266?hash=item23a7c8509a:g:jN4AAOSw9mFbFW9b
This is one i made, i used red coloured water in it but it was a bit thin, i needed to drill some hole's so the water wasn't sucked up through the tube's (see second pic), i reckon 75wt gear oil would be better It was ok for getting them close, especially after trying to sync the carb's with a bit of wire, but i bought a Carbtune Pro balancer set pretty cheap secondhand, was only used once before i bought it.
do you guys think some of my problems with my carbs could be due to lack of compression? Mechanic did say it was down?
compression is the foundation of a good running engine...If its under the lowest spec then it needs to be addressed before spending money anywhere....
does anybody know what the specs are? the mechanics said the compression was 100 99 90 89psi. Can you just test it with a standard car compression tester?
You can, but it may not be accurate. With these bikes, compression tests must be done with the throttle wide open and the slides fully lifted (or just remove the carbs). Those numbers, if accurate, are very low. Step one is measure the valve clearances.
ohk I did do all the valve clearances before that test. Sombody told me the shim i was putting in was big. maybe Ive mis-measured somewhere.
When you measure clearances and they are tight, you need thinner shims to get the correct clearance. If you put thicker shims in, you are decreasing clearance which will affect compression in a negative way.
dont like O ring chains...I buy the standard heavy duty chains, service them regularly (which I enjoy) and they are cheaper as well
I've run a DID H/Duty chain for the last 3000km's, it cost me $32 from the local bike shop, and i've only needed to adjust it once in that time, but oiled it a lot I will be giving my bike a few run's at the drag's soon and i'll change it over to an O'ring chain as they're a bit stronger DID gold o'ring chain, 428 pitch, 136 link's https://www.ebay.com.au/itm/DID-Gol...793323?hash=item1a5c3f2aeb:g:jJcAAOSw2iFbfhx6 I bought this one off ebay for around the same price
Chains need maintenance, that means keeping them clean. Most people just saturate the things in lube and ride away.
How do you know the O ring chain is stronger? I will not run an O ring on my drag bike for the simple fact of the extra HP required to turn the heavier/stiffer chain.
It say's so on the spec sheet from RK RK O 'ring is 5500 lB'S /Foot v's 4230Lb's/Foot on the DID H/D I thought my FZR felt like it went better with the non o'ring chain but without comparing it on a dyno it may have just been wishfull thinking
So my compression tester arrived today. From what I can interpret from the manual the compression should be around 142 PSI. How low would be acceptable. I will hopefully get around to testing this weekend.
Same kit I have be careful of the screw in adapters they dont always seal well...I use the push down rubber bung ones, but that means you need to remove the carbs or get a 3rd hand from somewhere warm the bike up remove carbs and all plugs..attach gauge, turn it over till the gauge stops climbing or 4 to 6 strokes if you cant see gauge face....
