True Jet kit for 2nd Gen Ventures

[NebularMan]

I have been a Venture fan for years and finally I recently purchased a used 2000 back in september. The carbs needed to be set up right but I did not want to do the spacer trick to them. My mechanic is designer for many tweaks and jet kits for various bikes so I went to him to talk about what to do. Since there is no true jet kit for the second gen Ventures he took my bike in on his dyno for a little R&D for a true jet kit. After numerous spins on the dyno and different needles he had a needle custom cut with 5 angles. It took the weakness out of the original lean stock set up. So after picking it up I went for a short ride today between raindrops. Road was wet and I am spinning the rear tire like crazy if I twist too much. Granted I have no trunk or bags on but whoa the rear tire let loose easy in lower gears. When I first got the bike back in september the clutch would slip at just a touch of the lever but never under power. Now it slipped with the added power till it warmed up some. Clutch needed replacement anyway and is on the winter to do list. Great pull power in every gear except I could not tell in overdrive only because I was not going fast enough. Need to get it on the highway to properly test that. Patrtial throttle response was greatly improved with instant response at a touch of the throttle. It felt like it pulled almost as hard as my Honda Magnas (12.5 sec 1/4 mile on the Magna) but I will update that when I can run my friend with his Magna. Cold start was pull choke out it starts right up, one minute later push choke in and it runs normally. That was a huge improvement over stock set up as it took a while to run normally before the jet kit. So overall this is a needed improvement for all Venure/Royal Star owners. Stock set up was way too lean. Once I can get some long runs in I will be able to determine gas mileage. I bet it is the same if not better than stock as you don't have to twist the throttle much to get it rolling more. I am also running K&N air filters and NGK Iridium plugs. Ivan knows what he is doing on these as he has many kits for older bikes that work perfect. You should see his cherry collection of 60s-80s 2cycle bikes in his shop. Best 140 bucks you can spend on your Yamaha! http://www.ivansperformanceproducts.com/xvz1300.htm

Has he done anything with a 1st gen Vmax or a 1300 1st Gen Venture?

 

I would be interested if he has.

Oh darn...

 

Now I have something else to addon to the bike. It also is another reason to take the carbs out & do the float adjustments.

I had Denden do a "Jet Kit" on my '99 before we went down to Texas in '07. He swapped around the jets in the carbs, there are 3 different sizes, so I only had to buy 2 jets to do the swap.

 

I dont remember all the sizes, and which ones went to which carbs, but the result was impressive. I remember being 2 up loaded doing about 80 mph heading into Beaumont and still got 38 mpg...I was very happy to say the least.

Silly me. I was thinking you really DID have a 'true' jet kit...and guaranteed to go 250 mph or you get your money back:
