Airsal=Shitty Aluminum

Ok, so my white and blue magnum is done, well almost. Turns out airsal aluminum is extra crappy. I was setting the timing, thread the spark plug back in, and go to gently torque it, and boom, the plug keeps twisting. Wonderful, now the head is stripped. I then proceed to attach the exhaust and one of the bolts in on the verge of stripping out the stud. I don’t know how I keep doing it (2 polinis now), but this is annoying. Luckily tom has some sweet inserts for the head, and I’ll just get an m8/m6 stud for the exhaust, but everything else is all done and pretty, so I’m kinda bummed. Regardless, it will be running for the weekend.

We had a pretty sweet ride sunday with a total of 20 mopeds. It was us, some mopedheads, so other san jose people are creatures elliot, bella, zachlee and josh. We cruised around up into the hills and stuff and it was exciting. The last part of the ride, through the twisty sidewalk in 7-springs was by far the best followed by sparks and shots at matt’s house. I heard we are doing calaveras next week, another amazing ride.

I rode the magnum and it did ok. I was kind-of leading because I always do, but I was topping out around 55ish but was initially running super lean. I tightened up a head leak and it was better but its still screaming at high rpms. I guess its ok because it survived, but I re-gasketed and sealed the head so that should help some more.

We built a new pipe for it the day before out of an estoril, stock magnum pipe, tecno header and hebo silencer. We de-restricted the estoril, added some tapered header, shortened the original header dramatically, and welded on the shittiest silencer ever. Its actually louder with it on than nothing, fucking annoying. Performance wise, its a huge step over the simonini with a large header and all, but its still not “pulling” like it should. I am going to mess with the ignition timing next. Yesterday I replaced the silencer with the one from my zen (stubby little one) and its WAY quieter. I’ll ultimately clean the welds and paint it black.

Comparing cuperhebo, n8p, simonini:

The newport is still around, apparently no one wants to buy mopeds right now, but I guess $800 is too much. I guess I understand the mentality that a few hundred more gets you a warranty from 77, but I dunno. This bike has been so dependable for me, my brother and his roommate that I really feel its worth the price. I might sell it to my russian friend who needs a new moped to get to school since he moved and no longer has his landlord’s available. The bullet is back on (after testing the n8p which actually performed amazingly, equal low end and really rev’d it out, maybe 40).

I might try to get the cobra this weekend, still chilling in the mountains.

Derbi is progressing, today I case matched it.

I hope to have a 2nd magnum going by sunday. cleaned the ltd tank today, getting the frame ready to paint.

oh yea, I fixed the magnumX today. Benji hooked up the kickstart spring, and after forgetting how to re-assemble, I got it together-puzzle!- and now it works great. The old spring had cracked. Now I just need a choke slide for the 17 bing.
