Nine out of ten times when you hole a piston it is due to timing being off. what cylinder/ head combo did you have on there?

stock cylinder and head. 30mm phbh carb and JL pipe. the stator has been on/off several times in the last few weeks... timing make sense, considering the other issues he was having (thought to be carb related)

we're pulling the jug off now. it's already a 3rd over bore. not sure about the cylinder. needs better opinion than mine. at a minimum needs a hone.

if you think the barrel is usable i can take the acid to it. i have to do that to my dr kit and it would be easiest to do two at the same time.

might as well open up the exhaust port and check all the port timings since this tuning helps get the heat out faster

after I fixed my port timings (smallframe) last year my temps lowered too
the barrel needs to be torqued down on the case for this work
if the ports are sharp they should be chamfered

and if you didn't know.... most nice expansion pipes like yours need the exhaust degs to be over 180

where is the scoot...??

gearless24 has the skills to make that barrel "wake up."

Scoot is back up in PDX with me with a big thanks to Joe! Big thanks to Gearless for all the shit he helped me with this weekend, solved a lot of issues with my stator plate! :D But then I blew up the piston :oops:

Not sure if the cylinder is going to be good with just a hone. I can feel some vertical gashes going up and down the cylinder wall... The piston is already 3rd over and there isn't a 4th over on any sites we checked, hell there isn't even a 3rd over that is actually in stock on the well known sites.

I would like to just proceed with the "ultimate vision" I had for the motor and put the Malossi 210 kit on there. It should play well with the other parts on the bike. It's a lot of dough to smack down but would also make for some good fun. All dependent on if I can get the money together in a feasible amount of time...

Question though, can I put a cosa clutch on the bike? It is an 82 p200e and both scooterwest and sip show that the cosa isn't compatible, what gives?

you'll want a jet kit with that new top end. bearings could be ok if you need to save a few bucks but not a bad idea, 200s are fast already, might want to check with al and see if there is a good option for a few less bucks,

I have a malossi 210 on my P, it has been there for nearly twenty years. If I was to do it again I would take a serious look at some of the cast iron kits as the nicosil on the alloy cylinder, although hard , is toast if there is any missadventure with the piston or rings. The exhaust stub on the malossi is also very soft which makes it difficult to get a good seal on the exhaust pipe.

I know I am in the minority here, but I don't see the return on investment beyond super stock upgrades.

I have to say, I've been quite satisfied with my stock p200 with a sito plus pipe. 8)

I understand the tuner's mindset and the desire to tinker and push something further. I love watching what Landon and Wil have gotten up to with their builds, and I feel tempted to try that too, but just for fun. Now that my P has become more or less reliable I want to leave it alone.

I could see building up a monster for fun, if I could afford the habbit. :twisted:

Al said he has the capability to redo nicosil in his shop.

the return is the in the eye of the rider and some times that is on the side of the road watching your pals disappear down the road...

I like the idea of super stock too...
- have that barrel cleaned up, ported checked, squish checked, bore clearance checked with the right tools
- order the same piston from where ever you can find it or see if Al has a 200cc barrel & piston that is not so far bored over...
- have Hot Rod Al re-profile that stock head

all this might take a bit longer to get done but I would check all this even with a new kit since they are all "off" a bit due to different cases / crank types / casting flaws, ..ect

cheaper too = $ 175.oo I am guessing
and
power comes in at a lower rpm

call Al asap
