  Not alot of heat right there. I think the blue and the black are pretty safe.

"THE BAT" MAN!!

[wordslinger]

...Indeed it is!!..annd Here's Another!!


..thiis is a pic of a ported intake...i want that...lol   

[thebatman]

had to have an air leak on the reed cage gasket..could actually see a SMALL piece almost in front of cyl. thats gone, sooo a new cage gasket has to be gotten, as soon as i can get one(if in stock out there at dal kawa)..... hope the blue will be a good temp fix

[thebatman]

wordslinger, what up man??? thanks dude........IS THAT NOT A CRAZY ASS DIFFERENCE COMPARED TO MY OEM INTAKE???  SEE HOW SMALL MINE IS?

[wordslinger]

...wow....that IS a big difference........

[sidthesloth]

Mate, cut a gasket, take about 5 minutes. Is the blue one a silicon one? Maybe ultra blue?

[thebatman]

yeah, its permetex blue rtv silicone gasket maker, not ultra...

[art]

 No doubt buy some gasket makeing material,can't recomend a beer can here though    Get a raw sheet of something you'll be making more at this rate 

[thebatman]

that does sound like a good idea....... probably cheaper in the long run...

[art]

Yep 

[sidthesloth]

Definately, I bought a sheet from Repco 250mm square, 0.8mm thick was $10, then at our local bearing place I found he had rolls 250mmx900mmx0.4mm for $4. I got two. This was how I adjusted the cylinder height after I made the spacer.

what up fellas??....anyway, she didnt die out yesterday and i had tried to jet carb...i have went up, BUT since the temp dropped about 10-15 degrees this weekend, alot cooler here high like 75....is this where a smaller jet works???..dont really know why...thought more gas=more power..smaller jet, scoot will be slower??   could that be why she stil showing a lean plug..i keep going bigger?  the plug even had traces of what looked like dried oil around the perimiter

[art]

  Running thats good  You may not notice a difference in performance between lean and proper jetting,your trying not to burn your motor up!
  Cold and humidity = less oxigen in the air= a ritcher fuel mix. Hot and dry = more oxigen in the air = a leaner fuel mix. You want to be somewhere in the middle and a little ritch if not perfect.
  You have made changes to the intake and porting. I like to go bigger on the jets till it sputters then start stepping down.
