kingkong Posted October 11, 2008 Report Posted October 11, 2008 i have a 421 cheater wit no timing advance plate. my question is what is your initial timing without a timing advance plate. mine runs jus fine and has plenty torque. really dont see what i could gain bumping up the timing. i know u gain alot on a racecar bumping up the timing but i really dont see how it will help this banshee. anyway what is the initial timing?

KaosBanshee44 Posted October 12, 2008 Report Posted October 12, 2008 Supposively it gives you a 2-3 horsepower range and better throttle response. It's just a easy plate to work with cause once it's installed you never have to take the flywheel off to make adjustments since you unscrew the screws around the flywheel to adjust it. Quote
sinisterboo Posted October 12, 2008 Report Posted October 12, 2008 Its 35 bucks well spent! as far as the initial timing, I dont believe there is an exact answer for that, because there are a lot of variables... Quote
quadgod211 Posted October 12, 2008 Report Posted October 12, 2008 yea its a diference.....my cub was at +4 and i took it to +10 and the diference was i was launching in 2nd on the vurge of bogging and at 10 it blew 2nd gear off.... but if you trail ride i would run it at around +4 or 5 depends on comp and fuel.....

POORBOY350 Posted October 16, 2008 Report Posted October 16, 2008 Im not real sure about timing either. i have a 421 cub (4mil 68mm wiseco pro lite pistons) with 20cc domes and my timing is at +4. and i was wondering what would the advantages/disadvantages be to bumping it up. or what could you even go to? not trying to jack thread...

J-Madd Posted October 16, 2008 Report Posted October 16, 2008 Here is the timing curve of the stock CDI. As you can see, the timing is never at zero (TDC), like we think, ....at least I used to think that. Quote
quadgod211 Posted October 17, 2008 Report Posted October 17, 2008 nice chart...i would really like to see the dynateks 4 diferent curves on a chart like that 1...... i think a dyna would be the way to go if you buy program software and all.... Quote

I've got them, but don't have a scanner, and the file won't post here. For those that have a dyna, know that the "stock" curve on the dyna is NOT the stock CDI curve. Quote
bigboybanshee Posted October 18, 2008 Report Posted October 18, 2008 Here's the dyna curve chart :thumbsup: Quote
dajogejr Posted October 19, 2008 Report Posted October 19, 2008 With the two cub motors I've built...I can tell you this. They love timing, they love compression, and they love fuel...period. Quote

505chevelle Posted October 31, 2008 Report Posted October 31, 2008 couldnt agree more!!!!! X's 2 I belive the same on drag ported stock cylinders as well. I just recently went from about +3 to +7, and wow! So now its at +9 :biggrin: LOL. Just check the heat on the strap of the plug and let it rip! Quote
POORBOY350 Posted December 4, 2008 Report Posted December 4, 2008 With the two cub motors I've built...I can tell you this.
