hi.
i have a 6 month old Standard350.
the problem i m facing is that the bike does not go beyond 60km/hr
the bike has done around 3021kms+.
Daily running is of around 36kms..
The bike has comlpleted 3 services from the A.S.S.
I told the problem to the mech at A.S.S. on the day of the 3rd service.
he said he will do the needful.
he tuned the carb but the bike still dint go beyond 60km/hr.
I took the bike to him the next day he said he will check the clutch plates, and he opened the clutch plates found nothing wrong put them bk and said he went for a test ride and the bike did arnd 80 -90km/hr.( i ws at wrk wen he was wrking on the bike)
since it was late evening and mumbai traffic did not allow me to go beyond 60km/hr.
Next day early morning i took the bike out at 6:30am. the bike accelarated really well ,gear shifting was extremely smooth but again it did nt go beyond 60km/hr.
My riding style is quite sedate i accelarate gradually and if the road is open i go upto 80-90km/hr on bikes. Can you guys please help me out .

Ok. Let's go step by step.

First check whether you are having a massive air leak by examining the intake manifold and the rubber hosing that leads to the air box. Does your STD350 choke for fuel(does it feel like hitting a brick wall at 60)? This could be the result of an extremely lean mixture.

Misfiring and choking for air will point out to an extremely rich mixture. Once upon a time, my LB500 had trouble crossing 80 when I jetted it way too rich.

Also, try riding with a new spark plug. This could be a possible solution if your previous plug is fouled.

Another issue could be a air lock in the fuel tank that could be stopping fuel at certain higher pressures.

Extremely loose pushrods(tappets) could also cause huge performance dips.

All said and done, it is very difficult to judge the issue without actually having a look at the motorcycle. I've done the best I know. I'll talk to my friend, Chinmay and get back.

Cheers,

Jay

Here you go.

This is what Chinmay Dangre had to say about the issue. There was a Bullet STD350 with the similar issue.

1. Valve clearance(push rod setting)..keep it bit loose in test ride it.

2. Check the spark plug color

3. Make sure the carb is set on 1.5 to 2 turns as applicable.

4. Since it's a C.B. Point bike, so check the timing.

5. If timing is wrong then symptoms are:-A. the bend pipe will become bluish B. Black smoke from tail end. C. Over Heating issue. D. Some times misfiring.

6. For better performance get hold of EI system instead of C.B.POINT. Much way better life and performance n ZERO issue in future.

7. Check the needle setting in carb. make sure it is on 3rd position from top. Well it's a new bike so i doubt about the change in setting but stil just to verify.

Cheers,

Jay

thank you for your replies Jay and thanx to chinmay also
1) what should be the color of the spark plug?
2)the bend pipe has indeed become blusih infact drak bluish
3)Is jerkin while the bike is running and hiss sound wen it jerks a symptom of misfiring
4)It does overheat sometime.
5) By E.I you mean Eureka's electronic ignition or OEM Enfield eletronic ignition? i'll b doing that after warranty period gets over

i'l get the rest of the tings cheked by my mech i will not go to the A.S.S.
thanks for ur help really appreciate it.

Iron,

Clearly a case of retarded timing which is automatically reducing your pick up as well as top speed. Since, you own a STD350, take it to a good mechanic in Mumbai who will set your timing correctly.

If the plug is chalk white, you are running very lean. The ideal color should be chocolate brown.

Cheers,

Jay

in my case the bottle coil was faulty and thats why it was not going above 65 on the speedo.

Since you are in Bombay, I can recommend Malik Auto, an authorised RE service center run by Malik (9892894789). All our bullets (Std 350, TB, 500LB) are serviced here, and I am sure he will be able to help you. His workshop is on the Eastern Express highway under the Kurla flyover. (Road leading from Suman Nagar towards thane.

In your case, as your bike is new, you should insist that the service center replaces the carb, plug, clutch and facing plates and set the timing correctly before considering replacing the points with EI. You could ask for and try bigger main jets on your old carb too.

Time to thank RE A.s.s for their expertise now by claiming warranty replacement for pipe asap. Burnt chrome plating rusts easy.

Good result Iron
I was confused when the machanic got 90 and despite your sedate style 65 was definitely unacceptable. If your bike is fitted with CB's there was a tendency for the igntion advance mechanism to seize not allowing the igntion to advance with increasing engine speed. Check the bob weights, pivots and springs on a regular basis.
