what sort of polini kit is it ?is there a funny looking stamp just inside the export port where the exhaust bolts up?

Great score! Flash 1 had that kit. Newb tuner I was at the time, and didn't break it in at all. Ran great nonetheless and sold the engine outright in 2009. As far as I know, it's running still.

Also is this for your af05? If so measure the piston. I'm pretty sure it will be a ~65cc kit if its for the 05.

[crimespree]

I measured the cyl. It is 47mm. Does that make the piston 45mm=65cc? Or does the measurement come from the bore? Paul there is no stamp. Jet is 90. I'm going run a uni pod so I think I should probably upjet. Any of you guys have a similar setup to get me pointed in the right direction as far as jet sizing goes

[Wheelman-111]

Greetings:

47mm bore multiplied by the shorter-stroke SE05 crank defines a fat but short cylinder whose volume is 65cc. SA16 cylinder is 41.4 mm tall, thus holds more. Volume is determined by the size of the box, or cylinder, in 3 dimensions.

[crimespree]

Cool thanks for the info. 65cc it is then. Oh well, better than 50 I suppose

[Kevinstonge]

My setup is similar on my nb50, but I'm still breaking it in so I'm currently running the 90 main with oem carb and exhaust. I'm not sure if you plan to add a 21mm carb and sp3 pipe, but I DO! So if anyone wants to chime in on jetting for that setup as well.........Please Share!!

Greetings:

The performance advantage goes well beyond the 40% displacement bump. Polini port timing and higher RPM just about doubles the horsepower, if you add the LV pipe. Speeds above 50 if you can gear it up a little, with the same or better take-off as stock. Speeds approach 60 with RedEft's 7.83:1 gears, albeit with painfully slow 0-10 take-off.

ps
heres my set up
ruckus variator , 3.5 tire , 1500 drive face spring , a 64 bbk ,
8 gram rollers, stock carb , after market air filter and 105 jet

[crimespree]

no tach, but i got it running today! yay super excited, it wheelies a little, super fun but im trying to go easy and break it in. keep an eye out in the build section. when im not lazy and had time ill make a post. the 90 main seems to do ok plug is reddish brown even soot coverage. so maybe a little rich.

what kind of speeds are you seeing? i didnt think the 3.5 fit on the af05 case. my 90/90 barely fits.

[crimespree]

I have a koso vari with dr p sliders. Graphite what is the better option that or ruck?

[swimmingfree]
