Make sure you can pick up a DJ180 ... you may need it.

I'm not familiar with the V&H jet kit so I don't know what they include in it. But if it has all the pieces needed then it's a good price for a kit. Before you start make sure that you know there is a difference in the numbering between Mikuni jets and Dyna jets and know which are in the kit.
But the best advice... read ALL the carb and jetting articles in the tech articles.

This is what it's included on the kit : MAIN JET SIZES 160, 165, 170, 175 QTY 1 ea.
1 fuel needle DN0977, E-CLIP DE0001, adjusting washer DW0001, needle spring DSP77, plug drill DD #5/32, screw DS0001 (STAGE 1 KIT)

It's that all I need ?? am I missing something ?? should I have bought something else ?? is it the Vance and Hines the cheapest therefore not the most complete kit ??

The jet sizes given on the website indicate that it's a Dynojet jet kit.

Most of those sizes are too small. We normally recommend about a DJ180 so make sure you can get you hands on one if needed. The 175 may be OK but you won't need the smaller ones.

Re:How often do you have to rejet ?? 2 Years, 10 Months ago  
Question for everyone on Loko's setup.

By opening up the airflow, is it sucking more gas straight through the carb? Thus dropping the gas mileage?

I drilled out my stock airbox (without rejetting yet) and I dropped from around 40mpg to around 25mpg. Same problem as Loko.

Is there a benefit to opening up the airflow, or does it just create the need to rejet? I'm thinking about putting my stock airbox (have 2 of them) without the holes back on to avoid rejetting.

What are your thoughts on this?

Thanks all.....greeny

People open up the intake and exhaust to increase the bike's preformance .... the stock bike is heavily choked.

However, to get maximum mileage with this new setup you need to rejet.

I know it depends on your setup , but what size of mainjet do you have on your bike ?? so I should definitely go with the 175 right ?? where can I get this DJ180 (does the DJ stands for Dynojet??) I bought that kit because of its price and did not think about anything else , being the moron that I am , did I make a mistake ?? should I skip putting this on my bike ?? what is the most recommended jetkit and why ??

So many questions I'm gonna have to start charging you.

Start with the 175 and try the WOT test. That should tell you if it's OK. If anything you many need to go to a 180, I doubt that you would go leaner (165).

Jetting kits are based on Mikuni and Dynojet (DJ) jets. I prefer the Mikuni but both work OK so no need to worry.
