Thanks @speedysprocket See you in a week. Can I send some flywheels back with you to get lightened?

I bought a used 4270 brain. It is supposed to have tags on each plug to show which module to use. Any way they are all gone. And I was wandering if any one could tell me which are which. Hears a pic of the colors. Grey blue and brown. Thanks guys.

I would bid but... I really want total loss.

What is KatieX?????

I have no regrets with my 760 build everyone that rides it likes it. I started with a chewed up 9/15 hooker and this season I put in a new 10/16. I will say I prefer the 10/16 over the 9 but since it wasn't new the comparison may not be apples to apples. I will say to only mod that I haven't...

Of course I'm in.

So I got to put a little time on the ski today. Specs are 115 low 125 high. Seemed like it was spot on at 3/16 turn out on the high screw. I'm going to play with the jetting more just to see what happens. But I might be done.

May need to double up on your anti siphon check valve. Would you say its dribbling at idle.

Thanks Guys. @Matt Jones me and Brian are coming down Saturday if yall ride around lunch. I think I have some jets for you and @jo5hi3. Brian has to be back in Statesville around 3pm so lets ride early.

Please explain. I do not know what you are referring to how do I check?

I think they are stock. they came on a raider I bought. They are black, have had the chokes removed and primers installed. not really very modded but it does require a little lower popoff.

Thats not what the mikuni manual says. Page 14. Not wanting to argue, just educate. Maybe I am wrong or don't understand. http://www.mikuni.com/pdf/sbn_manual.pdf

Yea. @jo5hi3 save those mains I might give them a try. @Dartman I have tried reverse jetting never really got the results I was looking for but I never went that lower I think it was 110h and 125 lows. Defiantly a softer hit than with 115 l and 132h. I think my total jetting is to high.

Ok. I thought I had some 125s in my box but couldn't find them. Went down to 115 l and 130h. We will see how that works I will report back.

Yea @Quinc I saw you were working on a blaster with a very similar set up to me. Where did you end up with jetting?

I have been working in from 1.5 turns out. Ski is progressively running better but what I'm trying to figure out is the 3/4 throttle thing. And fouling plugs.

So I just put a set of modded dual 44 carbs in my motor. Im running a r&d manifold, vf3 reeds, ported and decked 760. Ski runs pretty well but I fouled 2 sets of plugs yesterday. Not a lot of full throttle runs. pop off is 20 low jet is 115 high is 132.5. Off idle response is good, 1/2...

Best guy to deal with.

Doesn't Pump efficiency degrade the higher you get in rpm's?
