Well here is my current set up. I've got the WB slip on pipe with the K&N clamp on filter. 170 main jet, needle raised up one notch. I love the way it runs (quick as hell) but am still annoyed by the top end popping I get. I've been reading posts about the new Vortex CDI box. I'm considering buying it because it seems like when it pops it's hitting the rev limiter, just in a sloppy way. What do you guys think?? Might this solve my problem?? I don't want to dump 400 bucks into this thing and still not be able to revv past the popping.

THanks a ton,
Sean

I think the Vortex will be awesome for tapping out, Im getting one real soon, I think alot of people forget to make adjustments to the float bowl when jetting. I had no clue about this until I had a guy do it to mine, He said that this gets overlooked alot, mine dont pop I just Rev out.......

Every carb has a float level spec, you really should invest in the shop manual. The adjustment is done by bending the float tang that contacts the needle, with the float just contacting but not compressing the spring loaded needle pin you bend the float tang to obtain 13mm from the bowl flange to the float bottom...

Mine popped a-lot when it hit the limiter, with the jetting perfect. With the vortex cdi in posistion #9, all the popping is gone and you can shift when you should, not early to avoid the limiter.

What about in other positions?? Does it still pop in 1-8 and 10?

And one more question, If I were to adjust the float level in my carb would I adjust for more or less gas meaning raise the level or lower the level? And how do I know if I'm raising or lowering?

I have not yet tried all the different posistions, out of the ones That I have tried, the rev limiter is bumped up enough to where I don't hit it and get the popping. I will try out some different posistions this weekend as I will be at silver lake thursday through sunday.

Ya that would be great if you could give me that number..... also I haven't yet tried to go up to a 50 pilot jet, not too sure if I need to or not, seems to run great except for that **** top end popping.

Thanks
Sean

13-14 is for stock setting - i suppose with mods to carb and airbox you would need to raise the float - maybe 11-12 mm?

If you raise it much above 12mm you will have a steady stream of gas coming from the carb overflow tube. With the fuel pump functioning properly on the machine it should not need to be above spec...
