are you talking about constantly riding around half clutched all the time? If so your clutch wont last long..........at all. It would be like driving around with the brakes on all the time, as far as clutch wear.
ok thanks guys.and another question for you guys.um will it blow my engine if i have it the bike revving high alot or is that ok on a 2-stroke because are trail is alot of twisty turns and i have it revving high the whole time cause if i shift up it pretty much starts to bog down.so is it alright to have my bike revving high alot in like second?
You should know your bike enough to the point where to shift. If it feels like it has no power and your just reving the piss out of it then shift but just because your at a higher RPM dosent mean your bike will blow up.
The black stuff is "spooge" and is a sure sighn of a bike that is not jetted properly. The little CR's don' have the greatest seal system where the expansion chamber meets the cylinder so some is pretty typical but avoidable if properly jetted. Properly jetting your bike will fix your power delivery issues as well saving your clutch assy. some wear and tear. Bottom line is a fresh plug, properly jetted carb, good fuel & oil mixture and properly adjusted a lubed cables seem like they will have to riding a bike that feels vastly different. Selling this bike won't fix it when stuff starts to wear or need adjusted on the next one.
Honestly here's my $0.02 on this. It's a VERY real possibility that all you need is to adjust the air screw and maybe needle position unless your bike has some serious mods. If the bike worked fine before and now it doesn't what changed? Air temp? Modifications? Fuel type or mix? Maybe it's time for a top end or at the very least rings.
