Thanx for the assistance, It seems a set of 128MJ's and actually routing the air-solenoid pipe's has solved the most of my problem's. Especially thank you for the tip on the clear 3-way.

If I do have the 21's fly-wheel and all the other electric's are 18, how would this affect the system? I have the stock airbox in place and the reeds are old but seem pretty decent.

Would removing the airbox, (It is a track toy), affect the bottom-end significantly? I'm pretty adventurous and if it goes BOOM, I have an excuse to rebuild it anyway. What would you start with as a base for mains & other settings with a stock bike with only the airbox removed, bell-mouths in place with stock tied over. Environment would be sea-level and average temp of 25 Deg Celcius.

Finally, sorry for all the questions, would a 15wt Oil be overkill for an 85 kilo framed Lard-arse. The springs are stock and no one in South Africa has a replacement for me. I was contemplating machining a pre-load spacer but don't know if it would be worth the 20min of my life to turn them.

Many, many Thanx
Garth
