All of the valves are exposed to combustion heat, but exhaust valves are heated twice. When the. Valves that are anything but radically out of spec will have the same immediate symptoms as not changing your oil - NONE - the bike will run perfectly fine. As valve clearances shrink (the typical result of valve wear), but not so much minimal clearance goes away, the bike will run better as valve lift is increased Removing the cable end from the valve itself is pretty easy. You can see the cable end if you look at the exhaust pipe from the left side bottom. You can just leave the bloody cable there, it'll get pulled back and it won't get in a way So, after checking several forums and sites on the net, I finally broke the bike down today and checked the valve clearances. Here's what I found: Left intake = .006 Right intake = .0010 (actually, couldn't even get it between the lobe) Left exhaust = .016 Right exhaust = .016 So, looks like just about everything is off except for the left intake

Oddometer: 452. Location: SF, CA. On the right side, just noticed it. Bike is running pretty well.

Valve shims are available in 0.025mm increments, so the shims that can be utilized will also influence the new clearances that can be achieved. Once you have the correct shims in hand, the valve train can be reassembled. Use engine oil to lubricate the valve shims and carefully install them. The lifter buckets should also be lubed before. The exhaust valve creates backpressure at low RPM to effectively move the the optimal RPM for scavenging lower in the RPM band. That's how it's supposed to work anyway. In reality the system doesn't work super great on these bikes so people pull them out to remove the slight open valve restriction. 1 - 11 of 11 Posts SSR Dirt Bike Parts Parts. $3.95.

A four-valve setup is more commonly used on modern bikes or performance motorcycles. The configuration comprises of two large intake valves and two small exhaust valves. Generally, a four valve engine requires a DOHC (Double Overhead Camshaft) or two cams setup. One works the air intake valves while the other operates the exhaust valves Bottom Line: If your 4 stroke is hard to start, pops/backfires, is low on power, then it might be time to adjust or replace the valves.

The EXUP valve is design to give the bike some low down power. An exhaust works by pressure waves bouncing down from the end back to the exhaust port, then bouncing back to suck the next lot of burnt gases from the combustion chamber Valve timing, as stated aboove, does not affect the fueling. However, if a bike is out of tune in the valve department, it certainly could lead an inexperienced person to believe that there is a carb issue, causing them to fiddle with the carbs. For example lets say the valve adjustment at some point was causing the exhaust to pop If the valves are out of spec it can cause excessive wear to the valves and the valve seats. And even possibly have valve slap on the piston if they are far enough out. Eventually a valve will break and possibly trash your whole top end. Take the time and check your valves.
