jetting

I just bought a 1998 VMAX with Marks 4 into 2 pipes spark plugs seem a little rich does anyone know what the jetting should be? I'm at sea level maybe a 100-200 above it in California. I'm only getting 22MPG that seems a lot low to me for a bike and the last cruise I did I made sure I kept it...

Hey guys, I've been enjoying my Vmax for the past 5 months until the gearbox broke down and I had to park it for a while until I got it fixed. Now my problem is, and this has been going on since I bought it, it runs a very low mile per gallon, and by low I mean from full tank to fuel light...

Hey guys, I picked my bike up from the shop that jetted my bike they tuned it by ear.... It didn't seen to bad going around the block... When I got on the highway I noticed it was really rich and was loading up at crusing speed. Under wide open throttle it seems very rich as well... I have a...

i get 31mpg and i'm thinking of putting supetraps on. sean thinks i should jet the bike. How hard is it to do? I've never played around with carbs before and honestly a little worried. I see different kits, pills, etc. If all i'm doing is putting on some slip-ons what else do i need to do...

The bike is a 1985, with 46,000 miles, 2nd gear and valves just adjusted it has the k and n drop in air filter in the stock airbox. It also has the super trap slip on mufflers with the removable disks, the question I have is there any change to jetting after installation. I bought the bike...

Ok the long story short is when I got my bike I had the carbs cleaned in a "back yard" shop and the dude "ran a tiny drill bit" through my jets to make up for the low quality of gas since 85 he said... It has run super rich since then and now that the whole motor is torn down I think it's time...

Hi, folks, I've read the numerous posts about individual owners' settings and the overall jetting questions in general but I want to get a general "consensus" about my setup. I have to split the rack,.....again... because I have peashot, shotgunned, and Sea Foamed myself to the brink of insanity...

Finally getting somewhere. Few more fixes and this bike will be GTG... Below's a picture of where my current settings are running as far as an average, plug reading. I currently have 147.5 mains, stock needles shimmed 0.034. Air / Fuel 3 turns out.. Everything else in the carbs is stock. K&N...

Ok, Normally I'd just play with this thing and eventrtually get it right. But I think time is going to be an issue for me once I get this bike re-assembled right before a Vmoa run to the texas Hill Country in Bandera. My skins, swingarm and pumpkin are still at the paint shop so I can't...

I bought a stage1 dynojet kit and was wondering if anyone knew what i should run for a main jet. I have a k&n air filter and holeshot slip-ons. The kit says to use dj170, just think those are a little big. Dont know if i should keep the stock 152.5. Also needle height, i set them at 3 from...

well that damn mod monkey keeps making me spend more and more money. so, i no longer want to ride with my stock exhaust anymore and am hoping to go with a 4 into 1 exhaust sooner or later. heres my question. i live at 2700 feet above sea level. if i go with a 4 into 1 exhaust, will i need to...

I've heard all the bad things about the Dynojet Stage 1. Let's get past that for a minute. CaptainKyle's working on getting me the parts to go back to stock. Saml01 has offered to sell me the parts, Stock Main Jets and Needles if Kyle can't get them. I have over a week before Kyle is ready to...

Hey guys, Lets start off with jetting recommendations: I'm putting in a set of carbs with a morley muscle jet kit and DJ Stg7 needles. I'm looking for a recommendation on jets and needle clip positons and shims (if req'd) to get in the ballpark. My elevation is 1200-2000'. Planning to...

Ordered the 4-2 Marks today. Anyone on here have a good starting point on jetting , needle pos., mixture @ sea level, etc......with the exhaust? I also drilled my slides, so anyone with similar setup I'd appriciate your input.

Just installed a holeshot 4-2 exhaust, i also have the stage one kit, and was wondering what configurations you guys came up with for tuning? For a baseline its recommended to put in 155 mains and one shim under the needles to get started! Also has anyone taken off the Y on their air box with...

Ok, I know most of you that run the Kerker 4-2-1 have removed your baffle from a time or two.. There is no sound such as this:eusa_dance: The question is... Have any of you compared the A/F ration on a dyno with the baffle and without the baffle? If so was it leaner, richer, or not much of a...

Hello everyone my name is Ted and I'm from Spokane Wa. This is my first post and I'm just wondering if I should install the stage one kit that I have with my new Kerker that has a medium comp baffle in it? Will it work well or should I go with something els? I have a 2006 vmax with 2,400 miles...

Hello all, i have a Kerker 4-1 and want to put 4 single air filters directly on the carbs (removing the airbox). Is there a simple answer to the question which jetting would be the best for this combination????

I have a '94 "smogger" bike and have ALWAYS had ****** results whenever I tried to do any mods to the carbs. I have clocked barely more than 16K miles on it since I bought it new. I have always felt this is a pretty anemic bike compared to all of the other rave stories I read:confused2: This is...

i'm a software writer, not much of a wrench turner, how hard is it to change jetting, hp gain, do i need a real service tech?:ummm:
