Challenges with RD07 engine on around 4500 rpm

[praatika]

Hello!

Got my bike out of garage last Friday after a winter storage here in Finland. Has been a blast, only challenges being ice on the road (not plenty), cold fingers (it's around 2 degrees) and that engine tries to stall every now and then...

When tachometer shows around 4500 rpm, engine sort of dies for a split second only to come alive again. This does not happen all of the time but every 20 seconds or so. Sometimes it is really bad and there is a series of power losses this way. This is not related to an engine temperature nor velocity for the bike (read:speed).

It is the same at least to around 5500 rpm but sometimes I can ride like 5 km without a hitch.

The question is, you guessed it, any idea why?

I have just purchased an AT, i don't know much about them but i know they have fuel pump problems, so perhaps you can check that out.

You mention it is still cold where you live could the problem be carb icing? i had this problem on previous bikes, i don't know if it a problem on AT's

You mention that the bike was in storage for winter, did you drain fuel or replensh the fuel with a new supply, as i think the old fuel unlike good wine does not age very well.

Try this link, there seem a very helpfull group of people for AT's & TA's

By the way i was in Finland last year, nice country maybe going back this year

Hope this helps

Hey pasi

I had once a similar problem, and you know what it was? both battery cables were loose... after taking a screwdriver and 5 minutes of work, it was driving as smooth as a cat again. Like the AT usually does :-)
