Bullet Machismo 500 AVL LB-Goldie Silencer and 32mm Carb needed for performance?

[thangoorboy]

Hi Folks !

           I have a Bullet machismo 500 AVL LB, purchased here in  
Bangalore,India. Couple of my friends adviced that its better that I
have a goldie silencer fitted instead of the present long one,
originally fitted by the RE Company and also that for my 500 AVL
bullet, its better that the carburettor is changed to a 32mm one.
Incidentally the bike has done only 4000 kms. I had religiously stuck
to the recommended gear change speeds during the run in period. But
the maximum speed that I can reach is only 115 kmph and by then the
wind drag becomes very forceful.

Being a newbie, I would appreciate it if the seniors/professional
bikers in here could advice on the pros and cons of going in for these
changes and folks from India please guide me as to where 32 mm carbs
are available for sale in India? Goldie silencer is readily available
in Bangalore and that should not pose an issue at all.

Thanks in advance

Regards

Ajayan

Hi Ajayan,

I have a 2002 Machismo A350 and just recently have been wondering if
the exhaust system is different that the export models normally sent
to the U.S. and Europe,   It seems very loud and the engine doesn't
seem restricted in any way.  In fact, it runs so rich, I'm having a
bit of problem getting it leaned down.

It has the Dell'orto carburetor, and my feeling is that it is very
rich running.  Today I'm going to experiment with taking off the air
filter (stock) to see if that will lean it down some.  If it does,
I'll go to a K&N type filter.  I believe there are a lot of these
Dell'ortos still available there in India and suggest you may want to
try one.  It is the older slide type and is very well made.  I have a
new one coming out from a New Delhi supplier that is costing me $30
U.S. which is very reasonable indeed.  It seems a very responsive,
wide open carb., possibly too much fuel supply for my A350

So, I'm wondering if 1) you really need a Goldie type of exhaust, and
2) if maybe it might be worth trying a Dell'orto (but talk with your
mechanics there and see what they say), and 3) maybe going with a
freer air filter might be better.

Just some suggestions from someone not really an expert but feeling
his way along the bumpy road of R E!!!

Regards,

Lawrence

Ajayan,
And I think your friends are suggesting too much of a good thing.  
Better breathing is a good thing with these bikes, but I'd say that the
Goldie is louder than necessary, and the 32mm carb is bigger than
necessary. You can vastly improve performance, maintain good fuel
economy, and still have a bike that won't destroy the neighbors ... by
upjetting the stock carb, changing out the air filter to a less
restrictive one, and updating the pipe to something more open than the
stock pipe yet not so open as the goldie.

Thanks Lawrence for your reply. I guess for an RE owner, it¢s the journey along the bumpy road that adds to the pleasure . I will check with my mechanic whether a Dell¢orto carburetor and a freer air filter would do the trick. The 32 mm carb, I was told would cost around Rs.10,000/-, that is roughly 235$,  as it is not available in India and has to be brought in by someone coming from USA,
 
Thank you too Dave, for your suggestion on upjetting the carb. Will check out with my mechanic  too whether I really require a goldie or not. Anyways I thought I would take benefit of the advice too usually being given by the good folks out here.
 
I was worried about the drag, but  then I guess it is my riding posture ( sitting erect), that might be adding to it. Here for the 500 AVL machismo, they are offering a windshield, albeit, a very large one ( like the one that you see on cop bikes). Wondering whether to get one installed if it would reduce the drag. I am still puzzled why I am not able to push the bike beyond 115 kmph though.
 
Anymore thoughts on this?
 
Regards
 
Ajayan

For the best of both worlds, i.e., for Normal Street riding, and
occasional highway blasts it's recommended that you don't go beyond a
30mm carb (normal slide type). The engine would become overcarbed with
a 32mm and it will affect badly affect your city & town riding.

The Dellorto as suggested by others is a good choice for slighlty
better performance. Install a freer flowing air filter.

I was out today doing plug chops trying to tune the Dell'orto.  Mine
is a rich running carburetor, very responsive and well put together. I
have the Mik-CV on the Thunderbird and it isn't nearly a quick acting.
 Problem I was having is that my plug was sooting up and, in one
instance, actually fouled.  Too rich.  But I got in a dozen spark
plugs and started to do the chops and found that it was about right
for mid range throttle, but standing there idling, it was putting out
black smoke.  Then I took out the OEM air filter and just ran it
without one.  Amazing difference - no more black smoke and now it seem
a little too lean at half throttle, even though I lowered the pilot
jet pin by a notch (it had been at the top notch=maximum leanness).  
 If mine is any example (it is new) then the stock Dell'orto runs
quite rich, which I assume is what you are looking for.  Many of the
Indians got rid of their Dell'ortos, probably because they are more
fiddly to get right, or possibly they aren't as economical on gas. So
there should be some around.  At about 30 U.S. in India, it seems a
bargain.

I will still have to work on getting mine tuned just right.  This
includes doing something about the air filter, but the air is so clean
here, I can leave it out until I can order something in. What have I
learned?  Plug chops are a great way to tune carbs and OEM air filters
are very restrictive. I don't think my stock muffler, which is the
Indian and not the export one, is at all restrictive.

There was mention on this thread of up-jetting the standard carb.  What
sizes have people used? Also, and perhaps more importantly, is that
just the main jet or do folk adjust the rest of the jetting , needle
and slide height etc?  It is so hard to get this sort of information
isn't it?
I am thinking of replacing the factory airbox with the Hitchcock's
retro conversion/original filter and box mod.  Is that freer running?
Hoping for some good old fashioned prescriptive advice ;)
Thanks, Shiner, Orkney.

I found the following set up works quite well with an unrestricted
exhaust on the 500 lean burn.

 Fit a K&N DU-0100 as a direct replacement for the original item.
If you intend to run an unrestrictive exhaust then a 120 main jet  
in the standard CV carb will be fine and you'll need to richen the
needle settings by moving the needle clip to the lowest of the three
avaialable positions.
If you suffer spitback on opening the throttle after adjusting the
pilot jet as best you can then you need to remove 0.8mm off the
bottom of the slide, this will help richen the transitional setting.

If you run a 32mm Dellorto then you'll need a 130 main and lower the
needle clip to 4th notch (of five).

Until you reach full throttle, a carburetor larger than the one you
have will make no
difference.  If you fit a larger one, it will work less well at lower
openings.  Otherwise,
they would have put a larger one on to begin with.

The CV carb on the AVLs is a big improvement, and you'll have a lot
of bother finding
a larger CV.  Look for one off a Volvo if you're really hot for it.
They use them on Harleys.

Hi Pete, do you know of anyone who tried to put one of the side-draught SUs on a Bullet?  I've seen them on Triumphs and Nortons, and I fancy trying it on 500 and wondered if you've come across anything like this.
