Need to tighten drive chain on a honda ca 125 but bike only has a side stand; does the rear wheel need to be in the air in order to adjust using the adjusting nuts?

No it doesn't need to be off the ground.

But, remember that when you are sitting on the bike and the suspension is compressed there is less slack in the chain, so don't tighten the chain too much. Tighten it until you have an inch and a half / 3-4cm of slack in the mid point of the chain between the front and rear sprockets.

I have a derbi senda sm125 and when moving if i go above 5000rpm it starts jolting from the back wheel??? Any ideas what it could be?

Sounds like your chain is stretched and not fitting the sprocket properly or is just too loose. Check your front and rear chain sprockets for wear and ensure the teeth are straight. Check to insure the chain fits snuggly on the rear sprocket. As a chain stretches over its life, it won't fit in all of the teeth on the rear sprocket. This will cause the chain to ride up on the teeth at higher RPMs and jump (causing the feeling of a jolt or **** as it grabs again). Typically, the chain should have no more than an inch or so of play when properly adjusted.

Hi ive got a 125 ghost bike it recently threw the chain off and broke the magnito fixed that now the back wheel has started to lock up every now and then sometimes when pushing it a few mtrs or when riding...

Generally when the chain comes off it is because it is too loose or has gotten something in it.
There may be something lodged by the front or rear sprocket.
Did you check the teeth on both sprockets after reinstalling the chain?
Is the chain bent sideways? (not likely but possible)
Has the chain been properly adjusted since it came off?
Is the rear wheel straight in the frame?

the chain type is 428. take chain off and count # of links.give those 2 #s to parts guy. when you replace a worn chain,the front and rear sprockets should be replaced at the same time, because worn sprockets and a new chain will cause accelerated chain wear. count # of teeth on sprockets & give those 2#s to the parts guy also. if you want a longer wearing chain, buy one w/ the highest tensile strength,once again, parts guy can help you find that.dont forget,lube & adjust chain as needed.

Hot and cold plug difference

Hot Plug - has a longer insulator nose length - less heat is absorbed by the plug and transferred to the cooling system - the plug runs at a higher temperature - the plug is more prone to pre-ignition (if greater than 850 degrees C) - NGK BP5ES is hotter than a BP7ES plug. - An overheated plug will be white with brown spots. Cold Plug - has a shorter insulator nose length - more heat is absorbed by the plug and transferred to the cooling system - the plug runs at a lower temperature - the plug is more prone to fouling (if less than 500 degrees C) - NGK BP7ES is cooler than a BP5ES plug. - A fouled plug will be black and sooty.

How to choose the right spark plug for my bike?

only a handful will work with the motorcycle engine you own. Also different brands (NGK, Bosch, DENSO, Champion, Esc) will work better on different types of engines. As a general rule of thumb, use the sparkplug your manufacturer recommends for your motorcycle (same brand and part number). Unfortunately some spark plugs are very specific to a type of engine and make only for that engine such as the NGK ME8 for $34 per sparkplug, compared to the normal price of $3 per sparkplug.
