Hello guys,

I own a. 2008 HH karizma. Till date this bike has not given me any major problem but lately. There is one peculiar problem exists that is making me 'angry'[emoji41] anyhow coming down to the description.

The bike runs pretty smooth till 60kmpl if I go beyond that then the problem creeps in. Please excuse me if I don't sound too techy like most of the folks here are.

Anyhow the problem is like.. You will feel the bike is about to stall then it picks up again after few seconds it again misses then power then miss then power.. But if I keep it under 60kmpl there is no problem.. I took it with service centre guys.. Their answer is quite professional.. They said the bike is quite 'old' and keep it under 60kmpl. I use this baby for daily commuting.. To and fro From office which is 90kms (total)

I have done the following but still problem exists:

1) cleaned petrol tank for any dirt residue
2) changed the spark plugs
3) changes engine oil
4) got chain set changed ( because one stupid mechanic told that the chain is too loose and saggy and is rubbing against the cover[emoji29])
5) got air filter changed several times.. It has now green air filter as yellow isn't available anymore.

Any idea guys how to fix this problem?

Thanks!
