Not sure what to change?

[dantheman7502]

OK Finished rebuilding over the winter new motor, .20 over, super stock pistons, shaved head, all new seals and new crank stock stroke, stock carbs, fatty pipes, k&n filter, open air box. 32:1 fuel ratio. jetting as of now is 290 mains 27.5 pilots, and needle in middle clip. Run the bike on flat pavement or dirt road and it runs well, but in sand it bogs like hell, even with paddles on, could barily make it up bull gap in MI this weekend, even when i drop the clutch in 1st it bogs in the send unless i have the throttle pretty much pinned. i was messing with the needles and that didnt seem to help. when i do get on the pipe it runs ok. the plugs are a little dark but i havent fouled any. any help would be appreciated.

Where were you riding on pavement, dirt, etc? Where was the sand dunes you were riding at...was their an altitude and air temperature change? And to be honest, it's sand. You will notice your engine is bogging, etc if you are used to running on pavement because sand is heavy, harder to move...

You need to do a plug chop.

[dantheman7502]

well i was riding on both. but in sand it was horrable i know it will bog some but i couldent even shift into 2nd i continuously got stuck bc i would bogg so bad. This was at bull gap in mio, MI alt is about 1000ft or so and temp was 50's. I'v never done a true plug chop before, no where around i can do it safely. but when you cut the plugs do you use a hack saw or a pipe cutter or what whats a good way to go about it.

Hacksaw or whatever you have, I use a cordless sawzall.
