Late night tinkering.
Due to Second and Third Jobs, all I can offer the blog right now is a couple of images of late nights sneaking around the shop alone tinkering.

Ben Krenke uses his Destroyer Gilardoni combo to blow your sidecovers off. And check the temp gauge. No where near overheating!

Finally a new post!
Hello everyone,
I know it has been a while since our last post, but I promise it was for a good reason. Well, mainly we have been working on some new exhaust pipes. We have some new designs and will be doing a whole lot of tests to get them all worked out to make the best possible product that we can. Last weekend we started initial testing, just checking for the basics in a pipe, acceleration and top speed. We got some good results that will help us narrow down our designs for the next series of tests. We decided to use my magnum for these first tests just because it was handy. I wanted to get a starting point for the tests so the first run was with my standard set up. E-50, gilardoni, 24 Keihin carb, Destroyer, geared 16×36, medium port work. Acceleration was good it took 17.88 seconds for 0 to 50mph. Top speed was 66.2mph. We then switched to 18×36 gears and top speed went up to 70.3mph. That gave us a good starting point. We did zero carburator changes between pipes and monitored head temp just to be safe, all other tests were with 16×36 gearing. Next pipe up was new pipe #1 it took 21seconds to reach 50 and topped out at 66.1mph, I could feel it fuel starving in the low range so I know it can gain some more with jetting. Next pipe was Simonini for Puch. It took 22.19 sec. to reach 50 and topped out a 68.4mph. Next was N8P, it took 28.32sec to reach 50mph then topped out at 69.6 mph. After that was another new pipe #2. It did 0-50 in 18.23 sec. Topped out at 66.9mph similar to Destroyer, with just a little more everywhere. The last new pipe tested was new pipe #3, 0-50 was 27 sec. It topped out at 70.1mph. Two of the new pipes will move on to the next step where we fine tune some more and squeeze everything that we can out of them. Our next testing will include some graphs and some pictures. We will probably be using a less ported gilardoni and a mikuni carb since that is the more common set up out there. I just wanted to fill you all in on what has been going on here at Motomatic. Expect more updates in the near future.
Thanks, Nathan.

Just what I love the most
Aaron Vizcarra send in some pics of his completed Garelli SSXL build. He chose to get the Motomatic N8P pipe to add maximum top end to a moped already blessed with great acceleration. When we get pics like this from people that make great looking bikes it makes us wanna show up to work early and bust out. Your bike looks great Aaron. Thanks so much.

To be fair, this guy was doing hard labor before his lunch break. I can’t hate too hard.

Tranny gear slipping.
I had some unexplained tuning trouble in an E50 motor a lil over a year ago and eventually just quit trying to figure it out. Puch motors are so straight forward that after only a short time of tuning they normally come to life and run trouble free. Our good pal Chris came in to the shop wondering why his motor was running so slow and after a bit of trying normal measures he decided on a rebuild. When his motor was opened up we found that his tranny gear had moved over on it’s shaft and was dragging on the case. After looking at my old case, I found the same thing had happened to me and I had not noticed. So as a fix for Chris and I, Nate welded our gears into place on the shaft. I’m sharing this on the blog hoping that you all check for this bummer on your future rebuilds. You can even check it as a last resort on a motor that is acting funny and just wont tune in. Remove your clutch bell and look inside at a good angle with a flash light. Hope this may help.
