Please! Help! Know repeating common problems is annoying but need advice.

beyond the carb/petcock stuff, though a check of the petcock function and float needle seats is never a bad thing...because it's easy.
Just replacing stuff without knowing what needs fixing is expensive and is merely gambling. If you just like new stuff for future reliability, it's best to do one at a time and see if the bike develops an issue from it. Because...


-Often problems arise from the last thing you did before trouble began whatever that was.
-look for wire chafe toward the sensors and any ignition components. Connections too.
-I can't recall the differences in ignition timing for your bike? but while you're there, look for hangups at the timing centrifigal advance if you still have that
-"...valves and timing seem okay" SEEM? is this the last thing you did before trouble?
- Cam chain tensioner and check valve timing...at the cams.
-Check the spark plug leads
-Check the oil for gasoline smell (=bad petcock)

Please clarify... Did you remove the stock airbox and install pod filters?

It has the stock air box.

I agree it can be expensive. But even so, a lot of those things were probably needed anyways. I’ll work down that list again and make sure.

I’ve traced it back to the pilot fuel screws being too slightly turned in too far and too much slack in the cam chain. Anyone have luck with the ape manual cam chain adjuster?

I know it’s annoying. I’m young and learning. Not the most mechanically inclined person out there but eager to learn. Thanks again. God bless


I did valves again and did carbs over again after making sure timing was spot on. Bike runs like a raped ape above 3000rmps. Under that it’s a tad bit choppy. I can hear it, not feel it at all. Nothing to really complain about, but if possible I’d like to fix it. Giving it any throttle at all pulls it out of it. Other than that runs like a top. Is this something to do with the air screws adjustment. I messed with them for a few hours trying different combos and listening to the engine for healthiest idle. Is this a sign of Rich or lean? They are bs 34mm carbs I believe
