99RSV Carbs

[trandeod]

I believe my carbs are about to get cleaned up using the Seafoam and technical advice from Goose and some of you other techs. At least they're running smoother but the bike still revs between shifts. Another strange thing (to me) is the difference in the temp between the cylinders. Cylinders 1, 2, &4 run about 250 deg but #3 is about 400 deg.as checked with my handi dandi IR thermo gun. What temps should they run and will it hurt #3 to run 400+?? Will appreciate your thoughts. Thanks.

Hey Tommy,

V7Goose is "Da' Man", when it comes to your 2nd Gen. scoot, but I will try to to throw a few tidbits your way. If you have not put a new set of plugs in your bike since you started the Seafoam bath, then I would try that. Carbon (soot) that is washed from the valves and intake system by the Seafoam has a way of finding itself on the end of the spark plug. As far as the reving between shifts goes, Your throttle cables most likely need a good lubing. On the right handle bar, just ahead of the throttle, is the box that holds the run/stop switch and starter button. Remove the two screws from the bottom, separate the two halves of the switch GENTLY! You will see the push and pull cables that actuate the throttle. I start out with WD40 to loosen the old lube that has dried up in the cable housings. Insert the little red straw in the cable housing, squeeze off a blast of WD40, and repeat this several times. make sure to do both cables. Roll on the throttle a few times after a few blasts of the WD40 to move the lube thru the cables. You should start to feel the cables moving MUCH better after a very short time. I then use a throttle cable lube, (or in a pinch, 3in1 oil) to oil both throttle cables. After that I use the WD40 to lube the pivot points of the Carb. linkage, followed by a dab of the 3in1 oil.

If your bike doesn't get ridden regularly, (this means almost every day) then 2 OUNCES of Seafoam to a FULL tank of gas will help keep your Carbs. Clean and help it to run more dependably. If you went a little "crazy" with the Seafoam in your quest to get your Carbs. cleaned, and you are NOT taking your bike up on the freeway to find the rev limiter then definitely have a good close look at those spark plugs. (In other words, change them) If this doesn't smooth out your bike and warm up those "cold cylinders" then the Seafoam still has some cleaning to do. Which means take that bike up on the freeway and find the rev limiter in the first three gears until you get those Carbs. cleaned out. If you baby this motor, it will run just like a baby, not like the beast it was supposed to be. It's 15F here in Pennsylvania, and snowing!

Unless it's 15 and snowing there, I would be riding this bike ofter enough to keep the Carbs. from gumming up, but that's just me.

The more often you ride, the quicker this issue will resolve itself.
