  1. I believe so, but the top end was entirely set up by Adam so he knows the details. I'm guessing it was finding the right combo of the 62mm crank, rod length and squish clearance to give timings of about 190, 130. I just did the bottom end. The bike is really light too. I'd love to run it on the salt. 👍😉
  2. At the end of last years riding season I had what I thought was a blown seal. Bike idled fine but when put in gear and let the clutch out , the bike dies. If I feather the clutch and get the bike moving, it would run but I had to really over rev it. So I pulled the motor, had a third transfer cut in the case and cylinder and while it was all apart had the seals replaced. I learned some new info and thought I'd share. I was told that the spigot (the bottom of the cylinder that fits into the case) on rb20's is a little on the thin side and on some kits can warp and go egg shaped and pinch the piston. During the cutting of the new transfer, this problem was discovered on my cylinder. It was slight and corrected with a hone, but is an issue that can happen again. If it deforms alot, it can seize the motor. The solution to fix the issue is to resleeve the cylinder and use a smaller piston. Thanks to Adam Bower for the work and info! First, second and third picture is prior to 3rd transfer. You can see how thin the spigot is
  3. https://www.lambretta-teile.de/Engine-complete-40hp-Plug-Play-LTH-Quattrini-M200-V3$p@-on-Lambretta-smallblock A V3$p@ quattrini m200 on a Lamb case. Even on a V3$p@ it only makes 30hp (?). If it was that easy, wouldn't the tuning house that makes Quattrini kits just engineer that instead of coming up with the 210 for small blocks? Pretty cool if it puts out the 40hp they say.
  4. Hey Todd. I was studying some of your recent posted pictures and was wondering what the cable is/does on the flywheel side of the motor?
  5. In the gallery area on the site, can you make folders for your pictures or are all the members pictures mixed together? Is there a limit on how many pictures can be uploaded?
  6. A wealth of info. Far more detail than I expected! Did they ever make a serveta in ocher with the tv style panels?
  7. Yes, please post photos. I am specifically interested in tv side panel examples. So tv style panels with Li horncast and front fender would be factory correct?
  8. https://k2customs.co.uk/products/fork-spring-compressor-tool A different solution How to use it:
  9. I believe servetas had li style bodywork, some used sx style side panels , sx/ tv horncast/ headset on some models. Please correct me if I'm wrong. My question, is did any serveta model use tv/li special style bodywork such as side panels?
  10. I've never used an afr gauge but would be interested in details. What kind of number would be a good balance for air/fuel and where/how is the sensor mounted
  11. Not really sure what other people do, but I suspect since s.i.p. speedos have egt and c.h.t. gauge compatibility , that's what is most common. I have been using a westach 2 inch gauge for 15 to 20 years. I think if you have a tuned motor for touring or race, it is a must have, at least for set up. I prefer egt to cht. I can tell immediately what a change in carburation, plugs, timing, compression and weather does. Westach egt gauge is what I use. You will have to buy a thermocouple as well. I suggest the 1 1/4 inch clamp on probe. They do sell weld on sensor lugs that the thermocouple can be screwed into. They also sell a double 2 inch gauge for egt and cht. Be sure you get a gauge that works in the correct heat range. 100 to 1900 works well. How and where you mount it is up to you. I modified a second headset top, so I can switch back to a stock look. I have seen people using modified under headset mirror mount brackets www.westach.com https://www.sip-scootershop.com/en/products/exhaust+gas+temperature+sensor+_5001egtj
  12. All I can say is I've never had an issue with a rayspeed product. If I've had questions, they are very personable and helpful. Had various problems with no support with BGM and Casa performance. Go for it and let us know!
  13. Are the shouldered nylock nuts you are using designed to be used without a washer? I'd like to use a similar set up. Never saw anyone else use them and want to make sure I am using them what they where designed for.
  14. Welcome to the wonderful world of Lambretta aftermarket parts. No instructions and needs fiddled with to fit. Also only to be used on the race track
  15. Very cool. Looks great! Chain tensioner can be run with chain on top or bottom. Just depends on the chain length and sprockets.
  16. You need an A adapter type kit for non gp. That's what the engineers are for. Ha! I didnt say it would work, just a different way of thinking about it. I like the original tool.
  17. Not my idea but clever if you don't have the tool. Pictures taken from: http://blue-ashtray.blogspot.com/2011/11/blog-post.html?m=1
  18. What does it feel like riding on that surface? 4 or 5 speed gearbox's ? What stroke crank self destructed? Love the pictures! Bikes look well put together. Great job! Todd, how much does your bike weigh?
  19. Had a similar experience many years ago. I called the police just to get a report so insurance wouldn't give me a hard time. Also had a ton of receipts for parts that helped too. An initial inspection of how the bodywork fits is a good place to start. If panels, floorboards no longer fit tight or when riding the steering feels stiff or has a "gyroscopic" kind of feeling thats a problem. Good idea to take the headset top off and inspect the handlebars for cracks in the aluminum. Did he just drive away or stick around for you?
  20. Anyone familiar with the l.t.h. overrev variable ignition or s.i.p. variable ignition? I know the l.t.h. has 16 different curves to choose from and the s.i.p. has 2 depending on the cdi you choose (sport or road) . The directions for both are clear as mud. https://www.sip-scootershop.com/EN/Products/510029SD/Ignition+SIP+PERFORMANCE+by.aspx?_country=E993AB67-6807-4109-BBED-F6374EBF9F9B&gpc_origin=shopping&gpc_feed_alias=de&gpc_pid=510029SD&gclid=Cj0KCQjwhJrqBRDZARIsALhp1WTTXsFDygTukIDnxGK7v-Zgvw-R6aZRnxQNDrwYgDt4ConNQRQAOSwaAtZaEALw_wcB https://www.lambretta-teile.de/Ignition-kit-Overrev-12V-120W-with-rotor-Lambretta-GP-dl
