Drifter 1500 tugging???

[zlatko83]

Hello!

I am new here. I am from Slowenia and I drive My drifter 1500 (FI) since 2002. Before I have drifter 800. Nice bike
This summer I have problem with engine. I was made service (change oil filters, plugs,...). A month, it was work without problem.  Then start tugging. Usually, when bike stay a week, or more.
I start engine, heat the engine few minutes. It work normaly, with increase  hand throttle (like always). When I start to drive, the engine start to tugging (every few hunderd meters for secod or two, and then work normaly, and again)
It happen about 3-5 kilometers, than engine start to work normally.
It repeat about two month. Where is the problem?
Thank you and best regards from Slowenia
