Hi everyone,

Recently I told my mechanic to adjust the value clearance as I felt that my bike had a very bad response.He also did a job in the clutch.he said some bush in the clutch housing must be changed with the help of Lathe works.I can identify the item but donno the exact name.2 days ago I felt that my FE has adversely reduced after the servicing.so did some tests on the FE.

Test 1(insane riding)-37kmpl
Test 2(mixed driving)-40kmpl
Test 3(sane driving-not more than 60kmph)-42kmpl

I was really shocked.

all tests were made when travelling to college.total distance 25kms(10kms city,15kms NH)

Did all these with reserve to reserve method.

Mods Done:HP high flow air filter,1st rebore,100/90 soft compound tyre

Things that I would like to add-I assure that my bike runs lean.Also I would travel from college to home(to and fro) with just a litre.thats approx 50kmpl or more.

please help me people,I am in a tight budget now so have to save some fuel

Looks like the bike could be out of shape. However it can be brought back to normalcy with little patience.
First, post the picture of the "bush" that you are talking about. Did you check back with the mechanic who did the job?

Re: Low FE of 37 kmpl in splendor plus

1. Have you checked on the Spark Plug?? when did you last change it?

2. did you check the condition of the air filter?? when did you last clean it??

3. any recent work ion Clutch plates??

4. Did you clean the carb?

5. How old is your bike?

6. Did you fill up the fuel from the same fuel station?? Are you sure the amount of fuel being filled is exactly 1ltr?? after the bike hits reserve.. get a bottle, fill up 1ltr in the bottle and try to check the next reserve point..

I can't really get the pics of the bush.it comes in between the hub part and the pulley connecting to the engine.It can be changed only by drilling out the 4 reverts present there.i think it will be 4 or 5 don't remember.

1.check the plugs.stays white.changed a month ago.

2.the HP air filter was only changed 1 month and a week ago

3.refer previous post.also changed the clutch plates some 2 or 3 months ago

4.cleaned the carb long back.some thing like 6 months or more

5. 4yrs 2 months

6.only once different petrol pumps other 2 times same pump.i feel that it was a litre.for safety i usually fill for rs.80(74.14/lt)

next time will try the bottle method.

have turned back to the stock air filter today.will tell the results tomorrow.

Also i am getting misfires rarely.what should i check for that.

Re: Low FE of 37 kmpl in splendor plus

You sure the right grade of engine oil was poured after the clutch job? Sometimes wrong grade of engine oil causes major drop in FE.

Did you check with the mechanic again? Maybe he could recollect if he missed out any. These days mechanics are so busy that they tend to overlook things.

next time will try the bottle method - get a test can if you can (125/-) and it gives accurate readings.

have turned back to the stock air filter today.will tell the results tomorrow - let us see what happens. Did you also revert the carb settings?

Also i am getting misfires rarely.what should i check for that -
1. Check if there is water in spark plug caps/well
2. Check the ignition coils with the help of good auto electrician
3. Check if there is air leak at the exhaust system or at the carb boots
4. Check for water in the fuel tank or carb. Drain the petrol from fuel tank, pet cock and carb float bowl, clean it and refill with fresh fuel.

He is talking about the damper between the clutch housing and the secondary drive gear. I am not sure whether splendor had spring dampers or rubber ones.

Revert to stock filter. Please check if your valves are ok. Splendor is a very sensitive engine. Also check if the secondary air injector is clean. If it is clogged or its pipes have a leak you would experience drop in overall engine efficiency. The tyre you are running is a tad big too. The max i would suggest for a splendor would be a 3.00x18.

Rest do as suggested. Check plug. Check if you have good current. Check if you have a clean tank, clean fuel lines and a clean carb.

Rev your engine and see if any smoke is coming.

did the mechanic mess around with the AFR screw on the Carb??

Re: Low FE of 37 kmpl in splendor plus

spent some 45 mins yesterday and reverted to the stock filter yesterday with my younger brother's help.

had a run to the college today of 50kms.from empty tank to rs.100 fuel(approx 1.11l i think).tyre got punctured and lost the tube.so was late to college.so had to push the bike to the limit to get to the college(SRM).Got the feeling of a better FE now.roamed around for some 10kms and I have some fuel left now.Really happy thanks for the support and quick replies friends.You all really helped me a lot.thanks again.
[MENTION=19778]Bibhu[/MENTION]-yes it that thing you mention.it rubber in spendor.why I changed it was the reason of getting katak katak sound from the clutch.i think the work has been done fine because i am not getting that sound now and clutch feels very good.I could easily pop wheelies now

can you say the location of the secondary air injector.haven't checked it in my life.Also my tyre has a good rounded profile that the stock ones.so isn't the tyre contact with the road would be only a little more,just wanted to know.
[MENTION=61791]Cleaner[/MENTION]-I use only shell HX7 10w-40 semi-synthetic
[MENTION=27501]rreneav1987[/MENTION]-yeah few months ago before installing the air filter.I had the same problem of FE and after adjusting the AFR only found that the petrol tap had a leak.the mechanic also say that the bike is in perfect mixture if the plugs are white.but i have read some where it denotes a lean mixture.correct me if I am wrong

I know its not my place to tell you how to ride your bike but please try not to do many wheelies on the splendor as it was not built for that.

Even if the tyre is of a rounder profile it would increase the unsprung mass and increase rolling resistance putting more load on the engine.

The secondary air injector is locate just behind the tool box fixed to the chassis i think. It has a lot of pipes going in and out of it. Hard to miss.

A white plug means you are running lean which would lead to over heating of the engine. It was to be expected as you were running a ff air filter without upjetting.

Re: Low FE of 37 kmpl in splendor plus

rreneav1987-clutch slippage no way.i personally feel that the SS is better for the splendor.
