My bike give only 25kmpl - 2002 Hartford VR 150H

Hi,
You can track it through the manufacturer which should give you the year it was made.

Usually zmr dont have these kinds of problems.your engine bore is gone thats why your engine oil level is reducing.and the black smoke is coming out...usually these problem occur when you are travelling in higher rpm at lower gear...

The upright is a traditional looking bike and gives you the option to stand up on the pedals and really crank up the intensity of your workout. These bikes also work on many muscle areas that are not active while riding recumbent bikes.

Repainting via rattle-can is a bad idea - looks poor and will not hold up. As for forks, just google "overhaul threadless headset."

I’m happy to help further over the phone at https://www.6ya.com/expert/donald_f2ed37026a3ac881

Maybe this will help. This is a common problem that I have had with my GV250. Almost the same bike mechanically by Hyosung.

If the battery is low on charge and you are lucky enough for the bike to start. As per normal when first started it revs higher because the bike is cold, this turns the alternator fast to give you the electricity you need to keep the bikes computer working properly. Bike will warm up and revs drop down, alternater not turning as fast, not as much electricity being made. Bike will either stall or rev up and down irradically to try to produce its own electricity. This will occur when the battery charge is low and bike is at low revs, for example when you slow down for traffic or you stop.

If this is your problem. To resolve it when you are out on the road, keep the revs up, twisting your throttle gently when you are going slow or stopped. Give the bike a good long run on the open road to give the battery some charge from the alternator.

Make sure your battery is maintained. If you dont use your bike for a while it will lose charge just sitting there doing nothing. Give the battery a good deep cycle charge or take the bike for a good long open road ride.

Hello,

The chassis number(s) will not give the year of the bikes. The engine number(s) will give the year and location made of the engine only. This information would have to be obtained from the manufacturer.

The only way to determine the year of the bike(s) is to use the VIN number. The VIN number is 17 characters long and is usually located on the front of the frame.

This site, VIN Look-up, will give you all the information you need on your bikes.

Hope this helps and if you find this post useful, please vote. Thank You.

hi, the seats are a standard size if you go into any bike shop and tell them its a girls mountain bike they will then give you the correct seat, or if you want it measured all you need to do is measure how big the hole is across so look at the hole and measure it across the middle and that will be the size, but if you just ask them for a standard sized mountain bke seat they will then give you the correct one.

let me know if you need further assistance

plz rate this solution as i have a whole page of unrated posts, thanks

Go to parktool.com/repair for information on bike assembly, disassembly, repair and tuning. The assembly of any bike is more or less the exact same as any other, so this website will give adequate instruction for your bike.
