Betty's Back

I took my now 90% complete MZ out today, after it's whole needing a new frame and speedo's thing, oh and the me breaking my leg thing, and it was pretty damn good, just pooped myself nearly the whole time, and even took a picture
Yep it still needs new indicators, the side panels nearly hanging off and the engine covers off, but ya, chronic.

 

it looks well? How do you find the power delivery with that exhaust on?

I know the mz fans really rate the standard systems for even power delivery

 

It makes it rev alot better and the power delivery is rather sudden but if the revs are kept up through the gears it goes like mad
I personally hate the standard exhaust, it's too long, looks ugly and sounds like an asthmatic

 

looks like quite a peaky pipe, guessing the power kicks in about 5k

 

Mine had that long rod thing but for the spanny I made my own bracket that bolts to the passenger footrest to the exhaust

 

Actually it likes to tick over at 5k, power tends to come in at about 6 ish, it revs to about 9 and a half k

 

was just gonna say, it shouldnt be 5k for tickover.

Is the powerband of the pipe wide enough to keep it pulling without dropping off on gear changes? Was my pet hate on my old am6 engined bike. Ratios were far too wwide between first second and third. and only a 500rpm difference between 5th and 6th. daft lol

 

I know, it's daft, been meaning to sort the tick over out for ages
And yeah the power keeps coming through gear changes, but it's only got 4 gears anyway

 

Nice looking mz..my old man had a ts 250 back in the 70s m reg I think it was.flat head and a pipe just how you describe..if he left it running for any time...it was never where he parked it.Ging Ging ging Ging Ging ging...and the kicker would wolllop his knee into the squat bars it he didn't start it right..fun days

 

Took another piccy today

Does look nice that...cafe racer seat would look well good on it.

 

Been looking for a cafe racer seat for ages, can't find bugger all

 

am6 motors are all like that, theres a big difffernce between a 50/70 and a 125cc bike, i ride a lot of 50cc am6 bikes at work.
my gt idled at roughly 3k (that was a twin with some custom porting and advanced timing). theres plenty of cafe seats on ebay, the best thing is to buy an old seat for your bike and use the pan and mounts to remould your own.
