Performance mods for Bullet

[panky12345]

Hi, can somebody suggest me some performance mods for my Bullet machismo 1999 model?? like filters, exhausts etc. Basically, I dont want to compromise on FE, rather expect it to be better.

hello ! you want filter and then performance? emm and FE ???

emm IDEA! loss some weight off the bike. go for skinny tyres.

JK,In one of your silly moods..eh? Plane keri pokan nokku magaa...


99model Machismo.. is it a AVL or a CI?
Dude, get a better pod filter like a K&N/UNI/HP, the original filter is pretty restrictive. Then if it has the looong muffler replace it with a short one, the ones old bullets came with, or even better go for a goldstar silencer. But never ever fit a rocket silencer. If there's a cat con in the header pipe remove it. Upjet the carburator.

If you want FE as well do all of the above plus what JK said LOL Plus put CT100 crank,piston,bore in the bullet...

I'm not sure how much a filter would cost, but will it hamper FE in any way?

my machismo has the same engine as Std 350, no changes except the chrome. As for silencer, replacing one with std one was the first thing that i did....thump u see!!

Now what is upjet the caburretor?

[Sankar]

A K&N (model RC1060) would cost around 1500, a UNI would be a bit cheaper than that and the HP is the cheapest at 700. All three are imported, the HP doesn't have the cotton sandwich like the K&N but the filter size is almost same as the RC1060. The filtration of the HP would be bad (in turn wear out the engine faster) coz it doesn't have the cotton sandwich.

Fitting a filter shouldn't hamper the fuel efficiency, but you should upjet (meaning-putting a larger mainjet) and that could lower the fuel efficiency but only marginally. But FE depends a lot on the riding.

Your Machismo (if it has the Mikarb carburator) should be having 90 size mains, after the filter you should go for 95/97. You/your mech should decide on how bigger mains to use, the plug color should be light to medium brown after some good full throttle ride. It shouldn't be white (which indicates lean mixture) or black (rich mixture).

You can try giving it the 'boric' treatment. Put some boric powder (can get it from any grocery/hardware shop) in the engine oil. Make it 2-5% by weight (5gms, or 1 tsp per 100 ml of engine oil).

It isn't a direct performance enhancer, but it'll definitely reduce the friction and improve the FE and smoothness. If you are afraid, try 2% first, and you can always undo it by changing the engine oil. For more info, search this website with "boric powder oil" keyword.

Still want more? Try mixing some acetone in petrol/diesel.

Once upon a time i used t be die hard fan of bullet. Then my friend told me that his friend got a carb from japan which increased the power as well as mileage( 48kms). He was also telling about new spark plugs.

teh card name pls. and can you source it for me?

increased power and mileage? emm

and thers no once upon a time bullet fan

either you are still or your never was

[swathyd]

Yes you are right, it is like a volcano. can errupt at any time.
I have lost touch with that friend but i will try . another friend of mine has some info on it.

Dude, ignore my ignorance but I thin the AVL got introduced in later half of 2000- beginning of 2001. I bought my A350 in March 2001 and it was one of the first ones being solf by a BIG dealer in Delhi.

I may be wrong though. Thoughts?

Also, I am sure you are aware that the AVL engine is noisier vis-avis a normal one. Its been 6 yrs and 15,000 kms. Suggesitons to improve the sound. I have the short silencer (stock) - I think the long one came with the regular Machismo (non AVL) at that time and later got stretched further on the new model.

Will really appreciate any inputs/suggestions!

go for mikuni carbs... does wonders on ur performance.... i think it would be more than enough to start with

It sounds contradictory.

Unless the carb radically improves the burning efficieny and does some magic on the transmission losses, you cannot get more power and more fuel efficiency simulataneously.

It was done by a mechanic in nagercoil , his name i think is chokalingam.

first of all, free flow exhaust (simple remove rear part of exhaust). 2nd enrich fuel/air mixture otherwise chances are that you might end up with cease engine or blown gasket (my brother did that). no matter what you do FE will go down. otherwise changes won't be noticeable.
