Will it run? Taking bets!

After a few hours in the garage I have just a couple little things to button up. Then I will hit the starter and see if I screwed it all up or made it better.

Place your bets!

It's an '08 Scrambler, the US version with carbs. The bike now has stock pipes with the baffles yanked. Opened up the airbox this evening and pulled the baffle and snorkle and opened up the air filter retainer. AI came out last week.



Jets are now 130 mains, stock pilots, 1 shim under the needles and pilot screws out 2-1/2 turns. I'm at sea level.

I'm guessing the mains are good but it's going to be rich on the pilot screw and needles. I'll have to wait till tomorrow to ride it and see.

I don't see why you'll be rich on the pilot screws or the needle.

I'm running a similar setup to yours on my Bonnie but:
-NH Togas installed
-Baffled not removed yet

I'm running the 42 size pilot jets with the screws turned 2 turns out.

I have a vacuum leak on my bike right now so I can't comment on the performance but I don't think you'll be rich on your pilots or your needle.

Just my opinion though. And I'm sure it'll start just fine.

Took it out for about 50 miles of mostly freeway driving today. It runs very nicely. If it is a little rich it doesn't feel like it. It has great throttle response and pulls strong with no bog or hesitation that I found. With traffic I didn't get an opportunity for a good pull on the main jets but the mid range is great.

Since we're just playing and you're taking bets, my guess is you're a little lean on the mixture screw and rich on the needles. Even with wide open exhausts, the stock cvk's usually don't need a shim (assuming you're using the stock needles? I think the factory started using Thrux needles around '06, but I'm not sure). And the stock setup uses 2 1/2 turns, which is already running lean from the factory. So that's my bet.

Well, it's been hard to find good data for people using stock, or modified stock, exhaust with airbox mods. I found the link below from Ventura's thread when he was doing the A/F meter thing. He was using a Zard exhaust. With these aibox mods, he was using 130 mains, no shim and 1.75 turns.

If all else is equal, I should be able to lean things out a bit. I do wonder about the effects of our 10% ethanol gas here. It does lean things out so maybe I'm closer after all...
