What to torque the head on my 99 CBR 929 Honda in
For a 1999 Honda CBR929RR, the cylinder head bolt torque specifications are essential to ensure proper engine assembly and function. When tightening the cylinder head bolts, it's crucial to follow the manufacturer's recommended torque settings to prevent damage to the engine components.
For the CBR929RR, the cylinder head bolt torque specifications are typically as follows:
1. **Initial Torque:** 29 Nm (2.9 kgf-m, 22 ft-lbs)
2. **Final Torque:** 64 Nm (6.4 kgf-m, 47 ft-lbs)
It's essential to tighten the cylinder head bolts in the specified sequence and in multiple stages, gradually increasing the torque until reaching the final specified torque. The exact tightening sequence can usually be found in the service manual specific to your motorcycle model.
When torquing the head bolts, ensure you're using a reliable torque wrench calibrated in the appropriate units (Nm or ft-lbs). Always follow the tightening sequence precisely to ensure even pressure distribution across the cylinder head gasket.
Additionally, it's advisable to use new cylinder head bolts if the old ones have been previously tightened or stretched beyond their yield point. This helps maintain proper clamping force and ensures the integrity of the engine assembly.
As always, referring to the service manual or consulting a professional mechanic experienced with motorcycle engine assembly can provide additional guidance and ensure the correct torque settings are applied during the cylinder head installation process.

Should the power valve honda nsr 250 cycle every time I turn the ignition on@
No, the power valve on a Honda NSR 250 should not cycle every time you turn the ignition. The power valve is typically actuated by engine RPM and throttle position, adjusting exhaust port timing for optimal performance. It may move during engine operation but not necessarily during every ignition cycle, depending on operating conditions. You can buy new model bikes there are many new option available but first calculate your earnings stats on check here.

. One possibility is that the spark plug or plug wire is faulty 1. Another possibility is that the carburetor needs cleaning and adjustment It could also be due to a valve adjustment issue or a bent rod.
I would recommend taking your motorcycle to a professional mechanic who can diagnose and fix the issue. If you prefer to troubleshoot it yourself, you can start by checking the spark plug and plug wire for any damage or wear and cleaning the carburetor. However, please note that working on a motorcycle engine can be dangerous and requires specialized knowledge and tools. Please take all necessary safety precautions and follow the manufacturer's instructions when working on your motorcycle.

St1300 will not run below 2000 rpm
your bike has three different fuel delivery methods...choke , low speed or pilots in the old days, and main fuel rails or mains in the carb days. your choke or idle circuit is not working. on fuel injected bikes you have a relay which you need to get checked to see if it's a possible contributor. best to take to honda dealer and they can diagnose the problem. hope that helped a little sir.
When I first start my 84 Honda V65 SABRE, after
check for a vacume leak, as its been along time since i've looked at one of these is there a vacuum pipe on the distributor, this is the advanced timing if it has one on this engine, there is a diaphragm in this that over time can leak, this leaking would make hard starting on cold start if its failing.
2007 honda shadow vt750 dies sputters on acceleration
The problem might be with the air filter, and if not there are a few other things that could be causing your Shadow engine to bog down on acceleration. This includes a dirty carburetor, carb adjustment issues, or other internal problems like damaged vacuum lines or a cracked manifold

Honda CR250R. 2000 What the biggest size piston can go in a CR250 year 2000?
Question edited for clarity (again :) Always include full 'year make model' and in that order, as first 3 words please. That is the info that needs to leap off the homepage.
Question moved to model category (again :) There are over 10,000 to choose from.
The company that does the rebore will take care of all that. They are the experts, leave it to them. They will take it, measure it, bore it, hone it, supply the piston and rings
Another alternative is that they can bore it out and insert a sleeve and put you back to the stock size.
Before doing all this, have you checked for broken piston rings?
