Hi guys...,

Need a little help from u guys before I buy a used Comet 250 trading in my ZMA. I am a bit familiar with the single engine stuff (like ZMA, CBZ...

) but not a Oil cooled Vtwin engine (Hmmm..., yeah Definitely Not...

). Its a June 2005 Comet with 16k on the odo n Dual discs in the front... (yes two of them...

) n one in the rear as usual. It looks 'OK' from the exterior except some small stuff happened due to parking problems but I dont know things about the interior, "Engine Part"

. Kindly let me know what are the things I need to check n issues to b verified before I buy it.

Also let me know what would be the ideal price to buy it if the engine is ok....

So, kindly help me out guys...

Here is the pic of the bike...

The most important thing about the engine is that it has twin carbs . so tuning them is VERY difficult . you need to find a good tuner to set your carbs right . else your bike wont perform . rest you should not worry about anything . but the cost of spares is very high .

also i doubt if you will be able to get the spares from the dealer or in the market. Will the dealer still be able to service it for you ?? My opinion would be to search for an other good bike other than the comet. The servicing is sure going to be an issue.

Check for the chain sprockets. If the bike has clocked 16k kms then it is the time for the comets for a change in chain sprockets set which would be around 12k for the set.
Check the brake discs if those are proper. If the owner has taken care and changed the brake pads in due time then disc surface shouldn't have much of steps (as in when you rub your fingers through the discs surface, it shouldn't be very uneven).
Check the battery, a stock one runs for 2-3 years. The new one will be around 6000/-.
Tyre condition. Since comet has an unusual profile for front and rear, you'll have to hunt a little bit more for the tyres. If the bike has really run 16k and not ripped, used sanely i guess tyres can still go for 8-9k more.

Engine wise you can't tell much by riding once or twice. But by listening to the sound of both the cylinders you can probably get the idea about of how synchronized they are.
If the synch is bad then you should feel little vibration in the tank and seat area.
If the bike has been running in bad synch then the spark plugs need to be checked otherwise it should be fine.
For now I can't think of any more thing to check. Get the service history of the bike like where has it been serviced etc....

No bro... its just dust... i checked with the service history, its clean. its been serviced all the time by a kinetic trained mechanic who used to work for kinetic service exclusively for comet service, now he has his own garage for sbks at nagpur. Deal is almost done.., just wanted to take an informed decision with help of my fellow bhpians helping me out...

JOSH5898 · 08-29-2009, 08:02 PM
