Thinking about just new rings and piston, but an upgrade might be nice. Is the performance worth the cost of the 166cc kits?

Thanks new to my $400 08 3600 mile beater, and this group.

It depends on what kind of performance you are looking for.

Well yeah...but what are you looking for? Off line, speed, top end, street racer, mountain roads, flats, altitude, touring?

Is that the Malossi 166 kit you are thinking of. They like high revs, I would also at a minimum change the crank and beef up the clutch. Don't forget to rejet..

Just a little more oomph is all.

OK...it's tough to make any recommendations without knowing what you are looking to get. You will get all the help you need but you need to do your part too.

If you are looking for more "oomph" whick I guess means more power throughout the band I would probably suggest a DR 177 kit, higher performance pipe, upjet or go to a larger carb depending on what is in there now, and add a CHT. Timing will probably also need to be adjusted

It may be better for you to slap on a replacement stock top end and call it a day then go ride.

Here are the basics of moding

Fast
Reliable
Cheap

Pick two of the above

I did a Malossi 166 kit. It was a lot more than a bolt on. Ported, upped the carb to a 24/24, P200 tree, and custom full expansion chamber on a P motor.

That thing would smoke almost anything off the line. The pipe would really kick in at about 6,000 RPM Malossi loves the high revs!

For a reliable kit with a little extra "oomph" I would go with this

I run a CHT (minimum) on any kitted motor

190 seems reasonable. Just need to go up two main jets sizes at sea level?

Start rich then lean out. What carb is on there now? I'm not going to make any specific jetting recommendations. Add a CHT

Have you gone over the motor and retorqued the bolts. I would definitely retorque the head bolts before doing anything else.

Pretty sure its stock, and no idea what cht is.

If you don't know what a CHT is I would suggest staying stock.

just because I dont know what cht is, does not mean I cant wrench.

You can still wrench...you can also easily blow up a kitted motor. Look..I'm trying to help you out however it is now time for you to do your research, you to make your decisions, and you to assume the results.

A CHT is a cylinder head temperature gauge...it can give you an idea as to when the motor is getting close to seizing. In other words...the rear wheel totally locking up at speed.

Please play nice. And please do not instruct me on what terms I should use. That is unacceptable. Also I believe you meant to say "then say"

That is an accepted term in the two stroke motor(you will see people use 2T for these words, this is not "text talk") world. This is not "text talk" this is basic 2T motor talk.

It is obvious that you did not even read the thread I provided a link to; the thread oopsclunkthud wrote. That is the best explanation for gauges write up I have seen. As I said, it is time for you to do your own research.

I have made an honest attempt to assist you. It is time for you to assist yourself

Good Luck

Out

It is not necessary for you to send me a PM telling me to stay off your posts.

This is Modern Buddy. I have the privilege, not right, to post on any thread on this forum.

You have the privilege of beginning a thread on MB (MB stands for Modern Buddy). You do not own the thread.

I have been polite and truly tried to help you, however your attitude may be part of the reason that no one else has offered assistance.

Do not concern yourself with me posting on the threads you appear to believe you have ownership of. I was very willing to assist you. This is no longer true.
