Here are the camshaft specifications for 1986 - 2005 lift is .325 int .325 exh / duration at .050 is 236° duration at .040 is 240° make sure if you are using this for a comparison you check what they are measuring the duration at it seams no one uses the same thing.

No when my friend ported my heads we took the vboost off. It was real lean on the lower end so I swapped in 42 primarys which helped my bottom end. The dyno guy suggest 160 mikuni jets by the graph but he is a Harley guy and has not messed with a vmax so he figured drop the needles a notch or...

Anyone got any pointers to get this air fuel curve straightened out. The bike has a stage 7 kit.

This is my old max first time on a dyno. I have done all the work in my one car garage and this is just my baseline for tuning.

For everyone the replied thanks for the info. I ended up putting 42 idle circuit jets in from the 37.5 stock and I was able to get the idle circuit screws adjusted down to around 2 turns out from the 4 and 3/4 turns I had to have them at before. The stock jets were just not enough with the...

I moved the fuel vent hoses and that helped but did not solve the issue thanks for the advice. I love this old bike so my time spent working on it is not an issue, lol This bike was on an dyno about 6 years ago, i have done work since then, i will get it back on one soon.

I had the same problem with the idle screws on my bike the two carbs on the right as you sit on it. From what I have been told water likes to go into those to and sit in there and screw things up good. So what I had to do was get a reverse drill bit the size of the carb body hole and drill down...

I have them all ran down to the bottom of the engine currently. So they are supposed to be under pressure then? Everything eles I have ever had was ran down to the bottom the way I have it. Guess I can give that a shot though. Sent from my SAMSUNG-SM-G891A using Tapatalk

No there is no air box.

So I have a very modified 2001 Vmax and I am trying to get my carbs right. First when I say modified I mean it has the web cams 80-321's in it, a set of extremely ported and milled heads, vboost is eliminated, a set of Dale Walker 4 into 2 pipes with 6in cans, and individual k&n air filters. Now...

I have had my DW mufflers apart twice. Not to hard just drill out the rivets and get to work. I cut my mufflers in half last time. made it sound quiet a bit better in my opinion but it is loud just to warn you. The trick was getting the inserts to the right length. Oh yeah and you will need to...
