Boggs and wonte idle

[dkomarek]

Hey everyone, I need help!!!!

My blaster boggs down when I put a load on it, and it refuses to idle when I start it. I think it might be in the carb tunning or lack there of. Also some times when I kick it, it back fires on me, which is why I think it might be in the carb, or the timing. I was hopping that someone could give me some tips to help wake it up. Here is a list of some of the mods I have done. Any help would be appreciated.I:I

Vitos 240 +.10
Vitos +3mm stroker
Mikuni 35mm tmx carb (I know, an Air Striker would be better, but this is what I have to work with)
ricky stator adj timing 75W stator
Old Factory 7 style head pipe (not really sure of exact brand)
FMF power core 2 silencer
V Force Reeds
Boost bottle

That's about it that I can think of, please help me!!!!

When was the last time it ran right?

 

[dkomarek]

Before I locked the crank up, and had to do a rebuild. We bored it out, most of the stuff listed above are new mods, other than the fact that it was a 240 before it blew.

I also failed to mention that I added an aftermarket air box.

So this is the first time you ran it with the carb...
What's your timing set at.

 

[dkomarek]

If I remember correctly, we advanced it 5 degrees.

Did you get it ported to match the new crank? I hope so!

Is it detonating..Make sure it's not

Check your jetting

 

[dkomarek]

It's not a professional port job, but yeah we did our own porting and polishing.

And we have tried putting some different main jets in, but it hasn't made a diff, I was hoping that someone could give me some specifics on what exactly I should try, or combo of things, as far as the carb goes, I.E. size of jets; main, pilot, ect, needle position, air/fuel mix screw position, that sort of thing.

Yeah but did you change the port timing? (Like move the port ceilings and floors any)

I'd try doing a plug check unless it won't accelerate at all? and go from there..

Wish I could help you more Matbe try talking to the technical support people at Vito's if they have any...

bump!

 

[dkomarek]

Come on, anyone else have anything for me?

Could be a bunch of things. Start with jetting.
