火箭三R中气缸压缩为零。有人知道原因吗？

Journeyman said:

Your advice makes good sense. I see you have a Roadster, which I also did before the 3R, btw. You'd think the two would be very similar, and they are in many ways. But, I had to call on smarter folks here (credit to @Rocket Scientist) to understand why, when doing a valve check, the exhaust valves were so far out of spec. It turns out the de-compressors, which I was unfamiliar with, were to "blame."

I still don't think we have enough information to really help the OP, and given that it starts immediately and idles smoothly, I just don't think there's a compression issue, but something much more simple going on.

I'm about ready to step back until the OP provides a lot more information (and participation). I understand it's necessary to use Google translate, or something similar, but that is easy to do and doesn't limit how much information you can provide. For now....

Questions for the OP
When you did the compression test how did the plugs look?

Have you tried riding the bike? How does it perform? Is it fine at higher RPMs, for example?

Did you or the dealer do the 10k mile service? You're coming up on the 20,000 mile service interval which includes replacing fuel and air filters, spark plugs, valve check, and timing and throttle body adjustments.

Just a side question for the OP, what's the small square box you've mounted near the clutch master cylinder? I also noticed you had the 3 keys on a key ring sitting on the seat, I hope you don't use the bike with the 3 keys together as Triumph says this could cause problems.

Thanks for the feedback. I'm looking for a time to recheck for leaks. Because the engine isn't working properly, I'm afraid to try high revs. However, when I open the throttle, it stalls.

• Why, exactly, are you now considering the timing chain?
• Back to my earlier questions, starting with...
• How long have you had it?
• When you did the compression test how did the plugs look?
• Did you or the dealer do the 10k mile service? You're coming up on the 20,000 mile service interval which includes replacing fuel and air filters, spark plugs, valve check, and timing and throttle body adjustments.

You just PM me asking about tools need to "repair" the timing chain. We really, really, need more information in order to help you.

Ok, you answered the last one. It stalls when you open the throttle. That could be a lot of things TPS, fuel filter, for example. Bad gas in the tank- was it sitting up for a long time?

I personally don't think that "engine leaks" are your issue.

We really need some background information.

Send photos of what you are doing and some lengthy explanation, including answers to above questions, so we can help you.

Yeah, did you have the valves in the closed position? I'm picking you took the plugs out then introduced compressed air into the cylinder without making sure the valves were closed. If you put air in without closing the valves of course it's going to let air out, this will be why you got some out of #3 inlet - because it's in the open position.
