Question about rpm's

[scada]

I have a 2007 speedster 200 and my rpms on one engine is idle but the other engine is keep bouncing up and down , is this a vaccum leak? and is there any adjustment i can make possibly.

It could easily be a vacuum leak. Could be an adjustment with carbs as well.

Doc Honda or someone with better specific knowledge on the carb settings will chime in (hopefully, this place gets quite once winter sets in).

the rbm on the matter is bouncing but the engine is stable .

Dr Honda is a member here that has a TON of knowledge when it comes to two strokes and in particular Mer engines and out Seadoo boats.

I assumed you have carb'ed engines.

What motors do you have?

 

[Coastiejoe]

If he engine is stable I would be looking at connection issues. Grounds especially.

But again, Doc will know better.
