I did a engine flush after 33000 KM. I felt the engine smooth and mileage which dropped to 40km/l as picked up to 45km/lit.
For my saffire also I did the same after 47000 km. need to check mileage. saffire spare is the biggest problem. I have all the parts intact as/close to original except the speedo pinion. could not find a replacement after lot of serch yet. Bajaj is also not helping with any spare.
I am using it since jun 2006. It used to give me 48-50km/ltr with out pillion. Good pickup. I did a mistake by servicing at alaguindiran coimbatore. they convinced of making the vehicle better as there was a slight knocking..it made things worse..i had to take it back twice and it is ok now..but the average is around 40-45..i need to get it tuned again...
