250R Jetting issue, maybe!!??

[Endurance]

I'm picking up an 87' 250r tomorrow. It starts easily on the first kick, little to no smoke. It doesn't spit or sputter. It just doesn't hit like it should, it doens't open up!

When I ride it, it just doesn't open up. I hit the gas, it pulls and takes off but it doesn't really hit like a normal R.

You know how when you gas it, there sometimes is a slight pause, then pow, it takes off. Well this just takes of like a for stroke kind of!

The owner said something about it had a cold weather jet in it, so do I need to go bigger now with hot weather or what?

I'm pretty sure its a fuel issue. Can it be my reeds also, I have no clue!

This thing simply is not hitting the power band

Any help would be appreciated.

Thanks,
Bryan.....

As far as the temperature goes, richer in winter, leaner in summer.

Is the pipe damaged? Silencer clogged? Reeds? Carb clean? Could be 100 things. Just give it a good once over, it may something obvious that you have missed. Good luck, and keep us posted.

The jets are a 170 main and a 58 slow. The reeds are Boyesen carbon fibre and look great.
