I have a 2000 M2 I bought recently it has 3500 miles on it now and today I noticed when I open the throttle all the way the bike would stutter a bit and not respond like normal, then when I got home I looked around and noticed oil seeping from the area where the rocker cover joins the head. Would this leak cause the problem? And how common is this and is it an easy repair? | ||

very common problem, but an easy fix , just make sure that you do the updates while you are up there | ||

Please elaborate, what updates. And does that sound like a common symptom to stutter like that? | ||

You have a rockerbox gasket leak. In 2002, they came out with a better gasket - you need to upgrade. Eventually, the old gaskets will go on almost every bike, so that problem is not unusual. Unfortunatly, it has nothing to do with your hesitation problem. Sounds like it might be running lean? You need to clean your carb out first of all, and check that the tank vent is not clogged up. If the bike was left sitting for a long time, your carb could have become varnished. THis happens over time as fuel left in the carburator slowly evaporates. | ||

By the age of the bike you may want to go ahead and replace the intake seals. You can check the knowledge vault for info on diagnosing the intake seals, at least check to make sure the carb is fully seated in the boot to the intake manifold... Maybe just run some carb cleaner through a tank of gas if you are not ready to pull the carb off yet. Your profile doesn't show any upgrades on the bike, if it is bone stock you have a good place to start from. A rocker box gasket leak should not cause your engine to stutter, but you'll want to fix that before it gets too messy. Might want to check with DaveS or Al Lighton for a XB rocker box upgrade kit if you are gonna be in there anyway... | ||

Even if your M2 is totally stock, it could still benefit greatly by rejetting the carb. Rocker gaskets and carb rejetting are simple projects that are outlined quite well in the archives (and shop manual). | ||

Chris, You double posted this question. To save hassle in the future, just post it on one spot. You question was throughly answered in your first post by Jack and I. Easy fix for both issues. GET THE SERVICE MANUAL!! Brad | ||

I replaced the gaskets yesterday and no more leak, but the bolts used to hold the lower rocker were distorted and I ended breaking one off and had to extract it. Thats when I pulled the other two out and noticed they were junk. I was using a torque wrench so I know they weren't over tightened. Any one else have this problem? | ||

Is that the three smaller (5/16"?) bolts down in the bottom? I had no problems with those on mine. Sounds like someone might have overtightened them in the past. I guess the threads in the top of the cylinders were okay? I guess you'll know for sure in a few hundred miles. Good luck with that! You're a fast worker and have a good parts source too, I'd say.

yeah it was the three in the bottom everything else seemed good I did the front and inspected the bolts there and all was fine. Also I drained the fuel tank while I was doing the gaskets and refilled with new fuel from another station and no more stuttering. I like those type of fixes again thanks for the help. |
