I've been asked multiple times in the past to write a big bore kit installation how to for Minarelli/Jog/1E40QMB two stroke scooters. It took me quite a while to get around to it, but I finally did it. I would say it's a fairly complete guide to installing a big bore kit. If you were one of the folks looking for the info, here it is... 49ccscoot.proboards.com/index.cgi?action=display&board=yamajog&thread=556&page=1 |

I was checking that out last night before it was finished. Very detailed. Wish I had it when I had no clue what I was doing.
You have great writing skills man. Nice write up. Sure it will help many new people get the job done.

Thanks. Sorry, it took me a good bit of time to do. I meant to do it when I built the retro but somehow I didn't.

Thanks for the tutorial, I'm sure it can be applied to my needs on the Morini if I decide to go with a larger bore (which I probably will). All this tuning talk is making me itchy man.

Never messed with that style of engine, but I have a feeling it should be fairly close.

Great, great tutorial, Brent, best I've seen and I'm not just saying that. This site is destined to be a classic.

I was writing a guide to oil injection removal and switching to pre-mix. I got through a page or so worth of writing and my wireless mouse decided it was going to go nuts and close the tab. Tried to go back to the page with history, but it was blank. Computers are great most of the time, but wow they can tick you off.

Every time I write something long on here, I go back everyone once in a while and copy (ctrl-c) everything just to be safe. I've lost 30 minutes of typing more than once before. I don't let it happen anymore. |

I usually just do "preview" so I can go back and it will be there. If there's a problem when I hit "post" I can just use the back button. Didn't work so hot this time. The main reason I don't do copy and paste is if I'm using links to stuff it'll replace the links I copy or vice versa. There needs to be something like some games have for groups where you can ctrl+1 through ctrl+0 to bring up different copies.

I don't let it happen anymore. Same with me. When I write up long posts, I always copy them before i hit the post button. More than once I've lost an hours worth of typing just because something screws up after I hit post. |

The write up was very helpful Brent, except you didn't put anything in it about squish clearance. I've got my bbk installed and I've got 1.57mm of squish, is that good? I just wanna make sure I'm not gonna mess anything up after all this work.

For a safe and reliable street setup, I think 1.0mm give or take a little is good for most 70s. You can go tighter than that, but you have to keep an ear out for spark knock or if there are any signs of excessive heat.
