I went from 1.6s to 1.4s using the info in this thread. I was using 2.68 and tried everything i could to slow the arms down and couldn't get it done. Now I am using 2.86 and i think its alot easier to tune than 2.68 by far. I went from a 2.23 with 2.68 prim to 2.11 with the 2.86 and pulled that gear easy by tuning the clutch. Track time/seat and your time slips will tell you what direction you're going.

Hey bryan what is angel running against? Everything looks equal to 1000ft in the last 300ft there's a big difference in the mph... bike?

That's really fast for some stock cylinders! !!

nice!

80 lbs of spring psi with 4 springs?! Do you mean 80 lbs per spring? How are you getting that #??

Post some pics of the carbs..

This is what i use. http://www.everything2stroke.com/content/40-Gearing-Calculator-Banshee

If you are going to keep on gas 19x8x10 a.r sd23 would work well also.

The 18" tires is killing your top end...

I don't think your running out of gear with 18/38,that gearing is gd for 100+ in the 1/8.Something else is going on with your motor setup. A 19 sprocket would be a lot for 421 cub on gas..

Tim@Titan...

WTF!!! Just when i was starting to get this down! Bryan thanks for starting the thread and sharing. Your info was helpful to all us beginners in the clutch tuning world.

got one.

My bad.. jj@a Honda sprocket hub..

Pm me if u have one. Thx.

I'll throw my 2 cents out there about spring pressure and what worked for me. After I got back from the track I took out the springs that were in it and used those springs for my baseline. For example say that all 6 came out to 280 lbs. then I took the box of springs and kept taking 10% off the 280lbs to about 260lbs to 240lbs etc. Eventually my 60' started to improve and I knew exactly what my spring pressure was. I've seen 2 springs that look identical but they are 5lbs off now if you multiply that by the number of springs you are using its a huge difference.

I am looking for a stock/billet clutch basket that is in gd shape and doesn't have a lot of play.. send me a PM and let me know what you got

i have a +10 swing arm pc black that i would trade for stock crank in GOOD condition with gd bearing and no play..
