Hey amazing solid video man! I have 2 RPS hawk 250 enduros that probably have 300 miles on them each or less but I had no idea I had to adjust the valves before riding them. I bought all three of those things in your links and am going to adjust the valves before riding again because I fear I may be causing damage to them.

They all come tight right from the factory, from what I've seen. I'm not surprised that they would move around more either, the tolerance and quality control isn't as good.

Thanks for doing this video, sounds like you have the correct specs. I've seen some videos where they're saying adjust to as much as 004 on the intake and .005 on the exhauast. Sorry I listened to them, now I have to readjust the right specs. Tapping got real loud, and bike was even backfiring. Strange thing, my manual doesn't show valve clearance.

I'd double check the valve adjustment. If they're too tight the bike will start hard. Make sure you're using the T line not the F, and make sure you are on the compression stroke, not the intake stroke. Common mistake and it can make a big difference.

It could be the valves are a bit loose so they're ticking. Some of these engines are a bit noisy anyway and tbh my DRZ400 made a racket but was perfectly fine. I assume it's a 4 stroke, it would be worth checking your clearance and making sure it's in tolerance. Should be done periodically anyway.

So, could you tell any difference with the smaller head gasket? Was it worth the effort?

@skydcontrol

Жыл бұрын

I actually have no idea, I never even started the engine prior to doing the head gasket. In my experience with other engines it does make a difference. An increase in compression is an increase in power output. I'd do it again for sure, the cost was minimal and it's not overly difficult.

Engine sounds are super hard to diagnose without being there. Sounds like maybe just a ticking valve train. If you checked your valve lash and it's in spec then hard to say exactly but I like to start with decent oil and when you change the old check for excessive metal shavings or chunks.

Hmm, that's odd. Shouldn't really make a difference in top speed. Although if you fiddled with the carb at all while the valves were tight, it might need to be readjusted now.

Hey man, subcriber here. My question is what would happen if you were not actually on top dead center (compression stroke)? I did my valve adujstment and really took my time but I'm still paranoid I wasn't on the compression stroke/actual top dead center; checked a few off the list like making sure the valves were not moving up and down when reaching the ' T ' indication, also heard that you can wiggle the valves by hand if you're on top dead /compression stroke BUT I was only able to very very slightly; Adjusted with feeler gauges but my spark plug was in the whole time..so was just wondering how damaging is it to not be on the compression stroke then adjusting valves on exhaust stroke (before I eventually recheck my valves) by the way I noticed a sort of slight sputter sound coming from my carb (with pod filter) after valve adjusting and upping my main jet to a 115 because she wasn't starting with the stock 100main, my bike sounds way more like a dirt bike but with very steady rpm idle although I did switch to 86 fuel after using 90 for a while, may have an effect 🤔

@skydcontrol

2 жыл бұрын

It's actually a pretty common mistake for people to adjust the valves either on the exhaust stroke or not at TDC. It's usually evident right away you made the mistake as either the bike will start hard or sound like a tin can full of rocks. You can leave the spark plug in, taking it out just makes it easier to rotate the engine. Over time with the valves out of spec it could cause some excessive wear. If this was your first time adjusting them, and it's running good without excessive ticking (these engines are a bit noisy anyway) then personally I'd put some miles on it and then recheck the clearance. Just my $0.02 worth. I can't speak much on the pod filter because I'm not really a fan of pod filters and I'm not a carb guru. I can get it there but it takes me some trial and error. One thing to try would be going up a couple sizes on your slow jet and/or adjusting your air/fuel screw.

If you think you're running really lean it's best to change that jet sooner rather than later. A lean carb will hurt your engine more than a rich carb typically. If you find you have to choke it alot even on warm days - then you probably are lean. In the summer I can start my bike with no choke. Good luck, and you're welcome!

Welp when I went to go do my valves last night I got it done then today I wanted to see if it would run better I kicked it a couple times tried to bump start it and then kicked it a few more times and then I heard like the pistion or something in the engine making a loud noise so I tried to kick it again and then it’s like it’s stuck I can’t kick it nor bump start it so idk what happened

Probably going to have to pull it back apart and take a look, double check that you're at TDC on the compression stroke. There's a few different marks on the flywheel also so make sure you're using the correct one. Hopefully there's no damage, almost sounds like the piston made contact with the valves.
