Jetting help needed. Need a starting point

[Dave_Vmax600]

Ok so im building drag/lake race sled. out of a vmax 600. Right now the engine is getting the full rebuild.


what the engine will have is the following.... the big bore 700, thin head gasket, heavy porting, twin pipes, cone filters and possibly over bored carbs 39-40mm

anyway i would like some input on a base jetting point where i can start from .....with the carb over bore and without.

mains, pilots fuel screw adjustment etc....

any input will be appreciated.


Thanks, Dave

If I didn't like my 600 - 700 so much I would sell it to ya !!! This is what I'am running...Carbs;bored to 39.5,Q-8 nozzles (8AY's out 1993 Exciter SX) 62.5 pilots,a/s atleast 3 turns out,165 mains..I have Carbon Tech reeds,1 layer head gasket and I run the thing on VP RED race fuel..NO PUMP GAS !!!! The video shows how my sled works and that pic of me comming off the line at Loon Lake with Yammiegod,And he has a SRX !!!

This link is one we did for another carb - it is very close to a cross between a VM and TM Mikuni. It has two pilot jets - but there is some theory you can use. Look at Bob Hogg's tips

You may find this interesting as its not just a copy from a book
