Piston trouble - Enfield Bullet?

Leepower · 3rd July 2010, 20:05

Hi,
After a long, long time, I allowed a person to ride pillion (don't ask me who

) on my Bully (1978 Bullet 350). What I noticed was that the Bull was not strutting along smoothly in higher gear (3rd) after slowing down, not stopping. It was going too slowly. I felt it has less power. However, when I am riding solo, I never face such problems. My query is: IS THIS normal??? Or is there something wrong with my piston???? Help me out guys!!!!

Hi, Puneri, lets check your 1978 Bullet 350 (not the non parliamentory word) (aamhala Marathi kalat nahee ka ? Naughty boy

)
Ok apart from the joke please check the following ( of the bike )
1) check Chain tension , as the swiing arm moves under load it straightnes>thus tightening the chain , (happens with my Yezdi )
2) check for Swing arm bushes, as the bike is old
3) check brake settings > too tight
4) clutch slippage
Lastly if this dosent work you can ask following people in town
1) Pandit Jog
2) Mr. Mane near Hirabaug
Yours Sudarshan Vaidya ( Asall Puneri )

you are adding extra weight to the bike inturn reducing performance.. Ask the pillon to loose some weight!

Cheers!

Leepower · 4th July 2010, 00:25

Surdarshan, brake is not tight, I will check the chain and Swing arm brushes. The bike underwent a complete make over just 4 months back!!!
I always see a Landrover parked at Mangal Karyalay on the lane near Vaishali Restaurant. Is that yours????

And James, if pillion loses more weight, she will be too skinny!!!

Hi Lee,as far as I am conserned I prefer not to comment on the special pillion in your case (Such pilions are like 'dharle tar chavte & sodle tar palte'), so you better handle it yourself

Now for the bike following explanations
1) If the swing arm bushes are worn , the arm moves in such away that it tightens up the brake settings
2) If clutch plates are loose( inner bell nut ) or worn they slip under load
Thease are my general recomendations,not Bullet specific as I am not well versed with bullet. But I still suggest you that piston is the last thing you Open in case of power loss.
Yes the Landy is mine , see you some day
yours Sudarshan

A 60ish pillion should be nothing for and enfield with its massive torque. I've ridden with my friend as pillion totaling to a weight of 80 + 85 and it did not make a difference.

Did you also experience knocking when you felt loss of power?

I suspect the following...
1) Running lean?
2) Worn out clutch plates
3) Clogged air filter?

Leepower · 4th July 2010, 17:27

No Jingaboysr, there is no knocking... I will open the Bull up tomorrow and check out the clutch and air filter

rdna · 4th July 2010, 17:54

Did you check your tire pressure? Low pressured tires with a pillion is bound to feel sluggish.

Leepower · 4th July 2010, 20:48

Nope, it is not the air pressure. That is always optimum -- 28 in front and 35 rear that works best for me. Now, after Jingaboysr revelation I am gonna check the Carb setting too. The bike's been having hard starting since a week

Leepower
check the carburetor setting & petrol filter.(if you have it)
may be it is not supplying enough fuel .

edit: also check tappet settings.

Hi, Lee do you have engine compression gauge ? & standerd figures to check with ?
It will at least sort out the compression Question .
Yours Sudarshan.
